Device 00:1c.3 is one of the PCIe ports of the southbridge. Device 04:00 is the ASM1083 PCIe/PCI bridge. Devices 05:xx are the chips on the PCI cards. Bus 00: is the "root complex", i.e., CPU/northbridge/southbridge. Bus 04: is the PCIe connection between the southbridge and the ASM1083. Bus 05: is the PCI bus. "[04-05]" means that both buses are reachable through this bridge. > So it sounds like you are saying that the PCIe devices are assigned > an irq to be compatible with the PCI standard, but most PCIe devices > don't use the irq having another way to get the OS attention. There are different kinds of interrupts. 0-15 are ISA-compatible interrupts; the next four or eight can be used for PCI interrupts. (The interrupt controller (IOAPIC) has only a limited number of interrupt lines.) Message-signaled interrupts (MSIs) are implemented with a different mechanism and do not need to go through the IOAPIC; you can have any number of them, and they are never shared between devices. > Looking at /proc/interrupts, I see that ahci (which from lspci seems > to be the SATA controller) shows irq 42 even though the book says it > is sharing an irq with PCI slot 1 which has an ens1370 at irq 19.

For everyone here in Karlsruhe at LAC2014, good to see you all! I was wondering if someone would be kind enough to allow me to use some medium-awesome to full-awesome recording equipment for a short recording session during the next few days. I didn't bring my gear over and have a short fit of inspiration that I would like to capture. All I need is a decent audio interface and a stereo pair of mics (I would settle for a single mic, too). Please respond off-list if you can help me out. Thanks!

I'll be running now to catch the flight to Frankfurt/Karlsruhe. Just uploaded a freshly built OM (still beta) based on recent changes in the sources. Look here: http://repmus.ircam.fr/openmusic/linux The build is available as .rpm and .tar.bz2. This one changes to portmidi for midi playback. All midi-handling (files, messages, events) is shared between all 3 supported platforms, presumably making code more general and sustainable. This also means you'll need a (32-bit) version of libportmidi.so installed (but no longer need libfluidsynth.so). Im looking very much forward to come to the LAC (1st time for me).

The music is interesting. Quite straight forward mostly, but always with a surprising twist or detail. Permit me some criticism though. Your male vocalist seems insecure sometimes. Unsure of the melody line or maybe it's out of his preferred tonal range. Pity, since the voice is smoky and smooth, almost nostagically so. The lady sounds better though I hear strain there.

Oh wait.. thats me;) I'm pretty sure about the melody line but as you said, it's the tonal range (and my smoking, which I'm reducing) thats strenuous. We have a new female singer, who tops everyone I've heard with her powerful voice, and we're in the process of changing the songs to her voice rather than mine.

We miked the drums with a set of 6 AKG mics (Kick,2xToms,snare were dynamic, 2x condenser mics for cymbals/high hat). For Need My Sleep, we fed the drums into a mixer and recorded the stereo output with an M-Audio mobile pre. For the others we used a Focusrite Saffire 26 together with a Fostex VM200 to record the drums and the rest of the band to 10 or 11 individual tracks. For the singers we used a Sure 57 and an AKG mic, I've forgotten which, since the female singer left the band (We have a WAAAYY better singer now!!). So the guitar was sent through a Line6 POD 2, simulating a Fender Blackface and the Bass went directly into the Saffire. The walls in the room are covered with diffusive material to minimize reflections. Mixing of Need My Sleep and (preliminary mixing) of Faith was done in Ardour. Out There was mixed and mastered by a friend who uses Cubase+UAD Apollo+Windows, he really managed to get more out of the recordings then I did, when I tried to mix it. He has more experience. So its not all 100% linux as I'd like it to be, but I'll keep trying!

Unlike other hotkey daemons, it runs as a persistent, systemwide service and therefore can be used even outside the context of a user or X11 session. . It can handle a wide variety of devices (keyboards, joysticks, wiimote, etc.), as long as they are presented by the kernel as generic input devices. No kernel patch is required. The daemon is a userspace program that polls the /dev/input/event? interfaces for incoming key, button and switch events. A single daemon can monitor multiple input devices and can dynamically add additional ones. Hotkey handlers can be assigned to dedicated (tagged) devices or globally. . For example, this package might be useful on a headless system to use input events generated by a remote control to control an mpd server, but can also be used to allow the adjustment of audio and network status on a notebook without relying on user specific configuration. . Key combinations are supported as well as the hotplugging of devices using a udev hotplug script; the running daemon can also be influenced by a client program, e.g. to temporarily pause the processing of events or switch to a different set of hotkey bindings.

USB/other signal crossover to audio? Message-ID: Last night I came to at least a working resolution of a really weird problem. I'm hoping others can tell me what is really going on here, and what best to do about it. I am not an electrical engineer or electrician or anything like that, I just learned a lot from my dad and friends and trial and error. This has to do with my MIDI synth, which is a headless Linux box, often used with three Yoshimis running simultaneously. Input is just MIDI, either through USB direct from keyboards or through USB MIDI adapters. The problem is other really odd high-pitched non-static signals which are contaminating the audio, when plugged into any of three different PAs. The contamination has occurred no matter whether I use motherboard 1/8" jacks, FrontX RCA jacks wired into the motherboard, custom-built Switchcraft 1/4" TS jacks wired into the motherboard, a Prosonus USB, or a Behringer FCA202. It occurs to varying degrees, not predictably, with all of them. AC power ground lifts sometimes have helped, sometimes not, but not predictably: plugging into the same PC, one week the extra signals will be there, the next week about 75% less, et cetera. Same with different MIDI methods. Once I knocked out 90% plus by going from USB direct to MIDI through the Presonus, and then two weeks after that it went up again (still using the Presonus) to about half what it had been. I have tried AC ground lifts on amp, keyboard, and the box. Sometimes the signal goes away when there is nothing connected via USB; sometimes not. Good AC grounding has been explicitly made excellent and tested very thoroughly by at least two professional musicians at one of these locations. Perhaps the oddest thing I have noticed about the extra signal, sometimes, is when it comes. I usually connect the synth box through a Roland volume pedal to PA. If the pedal is entirely absent, it always comes. But if the pedals are there, about half of the time, the extra signal comes in most when the pedal is in the lowest/zero volume position, and least/zero when the pedal is in the highest/maximum volume position. The other half of the time, the signal is always there and always the same volume, no matter what the position of the pedal! About three days ago, reviewing for the umpteenth time the whole memory-history of this project, I remembered one thing I did a long time ago which seemed to knock out the extra signal altogether (back then, it was a 60-cycle hum): I used a Radio Shack inline-audio ground lift device, a 2" black barrel with two short double-RCA-male cables. I wore out several sets of adapters on that thing which is why I abandoned it. But it had worked more positively than anything else I tried. And I found other reports on the WWW of similar setups not necessarily involving 60-cycle in the problem signal. So I investigated the state of the art of inline audio ground lifts, found a whole lot more easily findable options than there had been then (might have been ten years ago), found that Behringer among others is making one using 1/4" TS/TRS, ordered the Behringer, tried it last night, and voila, lovely gorgeous silence until the Great Key-Pressing!!! So. I would like to rigorize this outfit a bit more; right now I have to play using the box plugged via Firewire into the FCA202, thence via TS into the ground-lift, and then to the PA via another TS. Here are a few questions. 1. I would love to be using 1/4" jacks built into the box. But clearly clear grounding is a terrible problem.

You refer first to > really odd high-pitched non-static signals which are contaminating > the audio and later to > back then, it was a 60-cycle hum My experience is with a high-pitched signal of stable frequency (actually mine was a hiss of 8000khz dropping to 6000khz for about second at the end). It seemed to appear "randomly", and was very annoying. I first checked for correlations in my apartment (does the signal appear in sync with the engine of the fridge, and this kind of things). But the problem turned out to be outside: the elevator! Although my apartment has no direct contact with its cage, everytime someone would go up or down, it would trigger that hiss. Once I found that, it became 100% reproducible. Searching in that direction I found that other people experienced similar problems, especially in recent flats with recent elevators (mine is 2 years old). The problem is linked to a kind of transformer which softens the speed variations of the elevator. The device is known to cause interferences and in theory it should be properly insulated... But those who install it sometimes skip that. Everything I tried to get rid of the hiss failed ... apart from disconnecting my loudspeakers from the soundcard. That would work, but it was not very practical. I suppose the metal coils in the speakers acted like a kind of antenna for the interference. So for a while I just notched out 8000khz and 6000khz where the hiss occurred during recordings. As it had very narrow bandwidth, I could aim the filter right at it and not loose much of the rest. Then two months ago I upgraded my speakers, and no more hiss :-) I'm not sure if I have understood your problem correctly. But if it's high-pitched and seems to appear randomly, you could check for something similar.

Input is just MIDI, either through USB direct from keyboards or through USB MIDI adapters. The problem is other really odd high-pitched non-static signals which are contaminating the audio, when plugged into any of three different PAs. To me, a high pitched sound like this suggests that something (or a combination of somethings) is marginally stable and different signal chains and earth loops can set it off unpredictably. If there is a lot of gain in the system it can even be something like speaker wires close to something not completely screened. Usually, TRS is used for balanced signals but there can sometimes be benefit in using it for unbalanced lines, in that the screening is separate from the return path - mind you, in some cases that can actually cause RF interference problems! All in all, I'd suggest going right back to first principles and connecting just the absolute minimum system (even if that means listening on headphones), ensuring you are free of the problem, then carefully adding bits. Do keep in mind that if the problem re-appears it is not necessarily the last bit you added that is at fault. It might just be completing a loop that triggers the real culprit. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

The first thing to mention, is that for this discusion, a keyboard that has USB out that looks to your computer like a midi port is not the same as midi itself. A 5 pin MIDI out and in are electrically isolated. The ground in the cable should only be connected at one end (output I think but some here may know better) and the input end is optical exactly to make sure there can be no ground problems. USB has a ground and +5 v both of which can cause signal loops. Most keyboards I have seen are not grounded... a lot of them being powered by "wall warts". My 80s DX7 does have a grounded PS, so you want to check that. Also, It will matter if you use the audio out on the keyboard or not (if you have any). > About three days ago, reviewing for the umpteenth time the whole > memory-history of this project, I remembered one thing I did a long time ago > which seemed to knock out the extra signal altogether (back then, it was a > 60-cycle hum):?

The normal way of isolating things is with an audio transformer (passively). often call a DI (direct injection) box with 1/4 inch in and xlr ballanced out. (There are active ones out there too, but I hate batteries so I won't mention them any more :) ) They come with ground lift, phase change, pads, etc. > then (might have been ten years ago), found that Behringer among others is > making one using 1/4" TS/TRS, ordered the Behringer, tried it last night, > and voila, lovely gorgeous silence until the Great Key-Pressing!!!

Sounds like I have to have the 1/4" > jacks on a non-metal plate; do you think? That would make no difference as most computer audio IF is a signal against ground. The only way to deal with it is an audio transformer to create an isolated signal to begin with in which case you want to go to XLR that can plug right into a PA mic channel. The TRS jacks in the computer are not ballanced but Stereo.... so next question: are you using Stereo out? If so you want two audio transformers to two XLR connectors. You can use adaptors to get two ballanced TRS lines (some PA line inputs will deal well with these) or a different adaptor if you really need an unballanced signal. Normally you would have a ground lift just in case it actually made less noise without the ground lifted :) a phase switch is probably of no use to you unless you also have your own amp you use for monitoring. > 2.?

Whenever I have the case > plate reengineered, should I have it done with TRS? Better to use the term ballanced or not. TRS doesn't, on it's own, mean anything... it could just mean you have stereo out. What you want is isolation... the ability to have no electrical connection from one unit to the next. This can be done optically or inductively (I guess capacitors can work too, but they can have other problems) > 3.?

Assuming you are using stereo, something like this could be mounted to whatever ground is around http://artproaudio.com/artcessories/di_boxes/product/dualzdirect/ or http://artproaudio.com/artcessories/di_boxes/product/zdirect/ The output connectors are isolated from the case. Many TSR connectors made for PCboard mounting have no connection to the case except what you connect as the barrel is plastic. But the costly part is the transformer in any case. Any music store (not electronics store or stereo store, but one that sells music instruments) will have at least one kind of DI box as they have been a part of connecting powered outputs to PA inputs forever... they were not new in the 70s when I first started playing. -- Len Ovens www.ovenwerks.net From nettings at stackingdwarves.net Thu May 8 22:44:00 2014 From: nettings at stackingdwarves.net (=?ISO-8859-1?Q?J=F6rn_Nettingsmeier?=) Date: Fri, 09 May 2014 00:44:00 +0200 Subject: [LAU] Ground lifts, TRS, etc. to PA?

Potential difference by getting the power from different main jacks or experiencing ground loops, because you don't care about a correct grounding are no excuse to give a life-endangering "hint".

JFTR if you know what you're doing a ground lift could be a temporarily solution, e.g. the power supply of the Brauner VM1 tube microphone has got a ground lift through a capacitor.

To be properly grounded, the connection to ground must have sufficiently low resistance, and be permanent in the sense that it can't be removed without removing power at the same time. Signal cables fail on both grounds (pun not intended). -- FA A world of exhaustive, reliable metadata would be an utopia.

Certainly not. Just read the text you posted. It says that some equipment may allow to separate signal ground and protective ground, and that in that case the two may remain connected via a capacitor which may improve HF shielding. It certainly doesn not say that you can disconnect protective ground, on the contrary it does say that you must not do that. -- FA A world of exhaustive, reliable metadata would be an utopia.

Hence why it is provided on every PA amplifier you can buy! BUT removing the ground from the mains input is not Ground Lift! As mentioned by others this is dangerous practice and should always be avoided as much as possible!! By that I mean you are welcome to risk your life in your own home if you really feel the need but it is never acceptable in any professional environment! EG from the well-known amplifier manufacturer, Crown: " The mixer, which drives the power amplifier, also receives its ground from the AC power cord. When the audio cable connects the mixer to the power amplifier the amplifier now sees a second ground from the mixer. If the mixer and power amplifier are both plugged into the same AC power strip then the mixer/amplifier interconnect cable shield can be cut to eliminate this problem. On most Crown amplifiers there is a "ground lift " switch on the back of the amplifier that performs this function and can be used to eliminate hum caused by ground loops" http://crownaudio.com/kb/entry/19/ As you see the Ground-Lift switch doesn't lift the ground from the input and that term should not be used it this is what you are doing. - Now what has confused me is laptops where I get a ground hum. IE 50/60Hz (plus possibly harmonics) hum even when using nothing but headphone plugged into onboard audio output, which is eliminated (or vastly reduced) by running off batteries or by using a PSU with no earth pin. Never quite understood why that happens when there is no connected piece of equipment for the signal to loop around...

Period. Although it might not relate directly to the OP's question, since the safety topic came up I would like to relate a story about one reason you should never remove power ground pins and make sure your outlets are grounded: Some relevant info: http://en.wikipedia.org/wiki/Cheater_plug Grounding is important not only for day-to-day usage, but in case of unexpected catastrophic failure. So this high-power powered PA speaker decides to SMOKE in the middle of a practice. Diagnosis, and a theory of what caused it: A component on the Switch Mode Power Supply board's +15V rail short-circuited. The short still exists, haven't tried to find the component yet, because: It appears that, at the exact moment of the short, the SPMS wanted to dump a lot of current into the chassis ground while things went haywire for a moment and the driver was still running and things shut down and caps discharged and so on. But here, the Input Board, which is fed by the +/- 15V power rails, was DESTROYED. The tops of all ten or so 8-pin op-amp ICs were completely BURNT and CHARRED open. More tellingly, in this model there's a 10-ohm surface-mount ground RESISTOR on the Input Board, connecting INPUT signal ground to CHASSIS ground. The resistor, and the circuit board area, were completely BURNT and CHARRED. (A mixer was connected to this PA, on the same AC circuit) Conclusion: I could only conclude there was no CHASSIS (AC) ground, or it was breached by a bad or loose cord. If AC ground had been intact, the catastrophic current would have been dumped into the AC ground and there would have been little or NO potential difference across the 10-ohm ground resistor to cause THAT amount of damage to it. The resulting wackiness in voltage swings could be what destroyed all those Input Board op-amp ICs. So the current wanted to flow into the AC ground but instead took the easiest path it could - through the surface-mount 10-ohm ground resistor, back through the INPUT cable and into the MIXER ground. (I checked: The mixer has no such resistor. Signal ground = chassis ground. The mixer still works. Still, I advised the owner to change his input cable.) Tim.

Proper grounding should never be taken for granted. A few years ago I inspected a set of 8 newly delivered active speakers - quite expensive ones from a very reputable brand. Three of them were not properly grounded. There was a short wire from the ground pin of the power socket to one of the screws used to fix the main PCB to the chassis. And those screws were black anodised... The scary part was that ground continuity had not even been tested at the factory. Regarding those 'cheat plugs', if I find any of those or any other tricks to defeat proper grounding on my watch, I take the same attitude as Joern - either those things get fixed *immediatetly* or the user can pack his bags.

Perhaps I assume too much thinking the proper handling of power and wiring is common knowledge. I deal with power issues on such a regular bases in my job, that I sometimes forget that all too often people are messing with power who have a very poor understanding of what they are doing. I work in large event audio-video-lighting production, so it's very common for me to be encounter power hazards that would probably give most people on this list the creeps. -Reuben From arnold at arnoldarts.de Sat May 10 21:53:32 2014 From: arnold at arnoldarts.de (Arnold Krille) Date: Sat, 10 May 2014 23:53:32 +0200 Subject: [LAU] Ground lifts, TRS, etc. to PA?

Its not professional encountering hazards and dealing with it accordingly that give people on this list the creeps.

It's the *only* safe way to work. Correct, and btw. the ground cable in the main sockets are always a little bit longer. However, for e.g. the Brauner VM-1 tube microphone it's similar done as described here: http://sound.westhost.com/earth-f4.gif The microphone is sold to all western nations, used by many experienced engineers. IIRC we only used a capacitor, however, we bought a capacitor that is intended for this usage. The switch to chose between a direct connection and the connection by capacitor was labeled "ground lift". You might call it hard-grounded and soft-grounded, all terms are equivocal.

Anyway, The timeout in qjackctl is (as indicated) a hint. The DE may choose a different timeout. I don't know which DE you are using, but in xfce there is a setting dialog for Notifications in with the other system settings. In my case I can change the look (theme), position, opacity and timeout. The default is 10s. Changing this would affect all of you notifications, not just qjackctl, but if that is distracting, I would guess others may be as well. If you don't want any notifications, don't start the notification app(let)... probably also a part of system settings. -- Len Ovens www.ovenwerks.net From louigi.verona at gmail.com Mon May 12 07:43:20 2014 From: louigi.verona at gmail.com (Louigi Verona) Date: Mon, 12 May 2014 11:43:20 +0400 Subject: [LAU] Help with configuring a laptop for Linux Audio work Message-ID: Hey guys! Recently I've bought a Lenovo IdeaPad B590 laptop. As it is announced as an Ubuntu-certified laptop (here), I did not think twice if buying it and thought that there would hardly be an audio problem - I've used Lenovo laptops before and audio worked very well. However, I was disappointed. Not only had I to use wired Internet, as wi-fi does not work without installation of proprietary drivers, not only had I to install a later kernel, as video card was freezing the system, but Linux Audio does not work well at all. I am using Xubuntu 12.04 with kernel 3.8 now. Here's what has already been done. 1. All real-time priorities and audio group and such standard stuff set up, checked and rechecked by myself and other people at LAC. 2. Autostatic was kind enough to help me turn off bluetooth and webcam, which did seem to help a little bit. His tutorial on this is here . However, my problems persist. There are two distinct problems. *Problem 1. Xruns.* Even if nothing is done on the computer and/or with audio, xruns are generated. For instance, since I started writing this letter, JACK was on and right now I have an indicator of xruns in qjackctl which says: 7(13). Note, no audio programs are open at all. If I do nothing, just turn on JACK and leave laptop running, xruns are also generated. *Problem 2. USB interruptions.* This problem occurs when I am using USB soundcard or USB headset. I get regular audible interruptions of audio signal. It has no bearing on xruns and occurs even outside of JACK, just when I am listening to Audacious, for example. I tried switching from PulseAudio to ALSA, same result. I though do not remember checking this with YouTube videos, for instance, and right now have no usb devices at hand to check. I would be very grateful for all the suggestions as it would be a pity if this laptop would eventually turn out to be not suitable for audio work. But I would rather find that out sooner than later, while I can still sell it and perhaps buy another model.

Did this include turning CPU Scaling off and setting _all cores_ to "performance"? In my experience this always makes a very big difference in quantity of xruns regardless of the sound card. Xubuntu doesn't have anything out of the box for that so you'll either have to use cpufrequtils or if intrested I've made a simple python-gtk front-end which sits in the tray for managing the task if you're interested... Also switching off (internal) wifi improves the situation here. > > *Problem 2. USB interruptions.* > > This problem occurs when I am using USB soundcard or USB headset.

I get the same problem with using the zoom H4 as a USB device and up to now found no solution. I recently got a zoom R8 and with that the issue doesn't seem to be present (although I haven't tested it much as USB device...) so I assume it *might* be a device problem. So.. good luck and do share relevant results, as I think some general 'laptop' info might be interesting regardless of brands. Lorenzo.

There should be a radio button on your keyboard linked to a Fn key to disable WiFi. Otherwise you could try unloading the kernel modules loaded by the WiFi interface or even unbinding them.

Tried your solution, I think it improved things a little bit, but not too much. It seemed as if there were smaller amounts of xruns, but still unreliable for recording things. However, I think I stumbled upon a viable solution. Harry advised me to turn off wifi. I did this using iwconfig eth1 txpower off. And what do you know? Not a single xrun in 20 minutes. I played around with stuff, recorded - all good. YAY! The only problem is that when I do iwconfig eth1 txpower on, XWindow crashes and I am left with no graphics and with even no ability to copy what the black screen says. So now I will attempt to turn off wifi module in kernel and then loading it back up and seeing whether this is as good for audio performance and then turn it back on and see if this crashes my system again or not. Will keep you updated and everyone huge thanks for helping me out with this. I am hoping this laptop will allow me to do lots of good tunes. L.V.

Unload the kernel module. On my laptop I had about an xrun per minute with wifi on which went to xrun per 5sec when off and vanished when I unloaded the wifi kernel module. Also, just checking: Are you using the stock xubunu kernel? There is a drop in lowlatency kernel available from the repos. With regards to ONDEMAND/ Performance, ondemand give xruns up to 10ms latency. (others I have talked to have reported similar experience) Even running my cpu locked to 800mhz does much better (with userspace) I don't have a problem here with performance, but if it makes things too hot for your machine, set userspace and set your speed a little less than full speed. Ubuntu certified means works with the desktop. nothing more. No one checks low latency audio on any of these things.

Nope, I had to install 3.8 as opposed to 3.2 which comes with Ubuntu. Looks like when you are buying a new laptop what you should do is put on the latest system available and I typically try to stick with LTS. Interestingly enough, I very rarely go lower 512 frames, which is around 46ms. And for some reason, midi is always precise even on 1024. I did test this and I remember I did work on a system where it made a difference, but not now. Louigi. -------------- next part -------------- An HTML attachment was scrubbed...

LTS is 14.04 with a 3.11 kernel, 12.04 should be good for another year anyway. There are two 3.8 kernels though, there is the generic as well as the lowlatency. The low latency kernel seems to get less xruns in anything I have thrown at it. There were a few 3.8 kernels that had USB audio problems, but I am pretty sure the fix got put in so you should have it.

I should have been clear, I have been quoting qjackctl's version of latency, so at 48k 512 would be 21ms... probably that is a calculated one way trip through jackd and of course doesn't include card delay. Certainly it should be high enough that CPU governing doesn't matter too much. I try to test before I buy if I can. Boot what you want to run from a memory stick. Ubuntustudio's (if ubuntu is your thing) ISO probably has the SW or enough of it preinstalled to make testing possible running it live. Other audio distros have live ISOs as well. I try to do the same thing with audio IFs. I walk in with my netbook and make sure it works with linux... and how well it works... can I see all the channels? can I hear them? (semi)pro audio is kind of hit and miss right now. Curious as to why you picked xubuntu over ubuntustudio. Ubuntustudio is based on xubuntu, but has audio set up out of the box and with 14.04LTS allows selection at install time of which SW not to install that is on the live ISO. Though, to be honest, I don't know what happens to packages those applications depend on if you don't install them. For example KDEnlive would have the kde libs on the ISO. If the KDE apps are not selected, do the kde libs still get installed? I'll have to ask. ubiquity does do some sort of clean up at the end of the install. -- Len Ovens www.ovenwerks.net From len at ovenwerks.net Mon May 12 21:24:34 2014 From: len at ovenwerks.net (Len Ovens) Date: Mon, 12 May 2014 14:24:34 -0700 (PDT) Subject: [LAU] Help with configuring a laptop for Linux Audio work In-Reply-To: <05e64421ee80f533394fb8a8f4b81a05@peterlutek.com> References: <53707EBA.5020208@gmail.com> <05e64421ee80f533394fb8a8f4b81a05@peterlutek.com> Message-ID: On Mon, 12 May 2014, Peter Lutek wrote: > On 2014-05-12 09:14, Len Ovens wrote: >> ...set userspace > > i'd like to do that; on debian, how do i make the userspace governor > available? i can load the kernel module (and it shows in lsmod), but > userspace doesn't show in the list of avilable governors which is returned by > cpufreq-info. Ok, I don't know. I have ubuntu-lowlatency 3.11 and I don't see any k-mod with lsmod that looks to me like it pertains to the cpugovernor. What governors do you have? BTW, the governor and speed can be set without the CPUfreq utilities. cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors should show what is available cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor will show what governor is in use on cpu* (put a number from 0 to 3 in) and writing to the same file will change it to whatever. Setting the speed is in the same directory scaling_speed maybe? There is also a file with the available speeds listed. -- Len Ovens www.ovenwerks.net From louigi.verona at gmail.com Mon May 12 22:14:09 2014 From: louigi.verona at gmail.com (Louigi Verona) Date: Tue, 13 May 2014 02:14:09 +0400 Subject: [LAU] Help with configuring a laptop for Linux Audio work In-Reply-To: References: <53707EBA.5020208@gmail.com> Message-ID: "Curious as to why you picked xubuntu over ubuntustudio."

I haven't done any audio work with it yet, but it now successfully plays videos on this i7 Haswell/Intel HD4600. That wasn't necessarily true with the Ubuntu 13 that came on it.

Hmm, do you have "boost" enabled in your bios? You may wish to turn it off as non-os control will change speeds on you if temperature gets too high. That may be why the top speed shows different. Boost is new on the intel chips, so if your system is even a year old, probably no boost.

Im going to check that, but what bugs me its that a week a go i could use jack with periods 128 or even lower and wifi turned on, didn't have to make any special change to use a lv2 plugin, but suddenly it started to Xrun on a plugin i made, naturally I though it was my plugin causing this, but as I tested it turn out that even with no connections or a jack client instantiated the xruns would happen with period 128. About the jackd command, the -P is not being fed because I set priority on default, and throughout this and last week I rebooted my notebook a bunch of times hehe, I was hopping to have some idea non related to jack priority, since I didn't change anything on jackd before it starting to xrun a lot...

Here is how I chose which person to give it to-- I got five identical coins (new(ish) U.S. quarters). I wrote the initials of each of the 5 interested persons on a separate quarter. I shook the quarters in a plastic tumbler and then dropped them from the tumbler onto a flat surface. I did this 30 times, and each time, I recorded any coins a person's initials on which were facing upward. I gave one free point to the first person who responded (MW) as a minor initial advantage for being first to respond. After 30 throws of the coins, here are the results-- FG - IIIII IIIII IIIII DS - IIIII IIIII IIIII II KC - IIIII IIIII IIIII II MW - IIIII IIIII III CM - IIIII IIIII IIIII III So, the person whose initials are "CM" gets first choice at the Delta 1010, if shipping and its cost can be arranged. Thank you everyone for your interest.

It does require more CPU usage, but you don't need to use as many plugins (EQ, compression, limiting, etc) to get a good basic mix. They do have some plugins to help tweak a mix, like the bass & vocal character plugins, mastering EQ plugin, etc., but they aren't necessary, you can get by with the Calf plugins. :-) Can't wait until MB3 comes out, it will have all of the A3 goodies :-) -- Brett W.

The front LCD display of this GeneralMusic RealPiano Expander module no longer works well, but if one can learn to use the unit almost "blind," using the front panel buttons instead of the LCD screen, this unit produces some very fine sounds from the digital samples and acoustic modeling, of piano, Fender Rhodes, Wurlitzer electric piano and several other types of keyboard or percussive (like vibraphone) sound. United States only, unless I am persuaded to try to arrange international shipping. If you are interested in the unit, please write to me directly (don't pollute the linux-audio-user email list), and please explain why you would like this MIDI tone generator, in case more than one person is interested and I need to make a decision about which person to give it to.

Now feeling lazy and wondering if someone's already done it. Hello Ken, I have built RT kernels for Raspbian. No debs though :( I could upload a tarball with the kernel and modules if you'd like. For what it's worth, I have better results with the standard PREEMPT Raspbian kernel so I actually never use RT kernels on the RPi besides doing some testing.

I have a couple of linuxes on my box: /dev/sda6 (LABEL=DebOld) is 32 bit debian /dev/sda7 (LABEL=Deb64) is a recently installed 64 bit debian Both these work ok. Both use xfce. Now I want to share the home and I am having issues... On DebOld home is separately mounted from /dev/sda3 On Deb64 home is part of the root fs and I want to move to using the old separately mounted home where all my stuff is The problem is that the numerical id of the (my) username is different in the two systems. In DebOld the id is 1001 in Deb64 it is 1000. So I did: In new (Deb64) change 1000 to 1001 in /etc/passwd and /etc/group against my username. Knock off the password in /etc/shadow and regenerate. To some extent this has worked. However now I am beginning to see problems suggesting this was not such a neat hack! So parole - the xfce media player - is refusing to play sound files from the old (and renamed) home but is playing it from the new. I am guessing this is a user perms and not really a parole issue since parole plays ok if started as root So I have basically one specific and one general question: Specific: Any ideas about how to make parole (gstreamer) work? General: There may be more such issues in other (sub)systems/apps. Whats the general way to solve it? Thanks Rusi -------------- next part -------------- An HTML attachment was scrubbed...

I am pleased to announce immediate availability of a competitive 12-month iPhD research assistantship in Human-Centered Design program for the Fall 2014. Virginia Tech's new individualized Human-Centered Design (HCD) iPhD transdisciplinary degree is closely aligned with the newfound Institute for Creativity, Arts, and Technology (ICAT). iPhD is a degree designed primarily to support individually tailored PhD experiences, allowing students to actively participate in shaping their plan of study. The GAship in question seeks candidates with a solid research background, and a strong sense of independence and self-sufficiency. We are particularly seeking students interested in sonification, sound spatialization, and interactive technologies (e.g. mind-body technologies, laptop/mobile orchestras, hyperinstruments, installations, mobile/wearable computing, etc.). Candidates must possess a strong knowledge of Max and Pd/Pd-L2Ork programming environments. C/C++ programming (or equivalent) is also preferred, as well as skills in other domains (e.g. interactive multimedia, K-12 education, 3D animation, etc.). This is a 12-month renewable assistantship with a full tuition waiver and one of the highest paying stipends at Virginia Tech. To be eligible candidates need to apply, be accepted, and enroll in the new HCD iPhD program with primary focus in the computer music domain focusing on one or more of the aforesaid areas of interest. The successful candidate will be given an opportunity to participate in shaping the cutting edge 130+ speaker system and consequently its innovative spatialization, sonification, and immersion approaches in the new $100M Moss Arts Center and more specifically Institute for Creativity, Arts, and Technology's three-story Cube space and its smaller counterpart, the immersive Perform Studio. They will also work closely with ICAT faculty and students on a number of collaborative projects, including Tech or Treat, MAKEr camps, as well as ICAT IMPACT studio initiatives.

Hey hey, this is beautiful music Gabriel, thank you for sharing it freely. 'Time will tell' actually gave me goose bumps. I'd love to have a voice like Megan, so compliments to her as well! I will also have to look up Glen MacArthur again, a cunning impression of Freddy Mercury, is what he gives me. :) The production is very impressive! I look forward to the continuation of your articles and hope to glimpse a few secrets! If only the drums in the first two tracks hadn't been that loud... It was distracting. The kit sounded cheap, since it puts me in mind of my first synths, where I'd used to pitch sounds down more than I should have to achieve a sound I didn't have.

Also, I can offer my meagre skills of live poetry reading mixed with live electronics, if there are any venues for that sort of thing that are interested in attracting amateur performances.

I recently moved to a new flat, and I've just got my studio properly setup in one of the rooms. Problem is, the room is rather horrible acoustically. As this is the room I've got to play with, I'm going to have to make the best of it acoustically. So, my question is about DIY acoustic absorbers. I'm most likely looking to build absorbers both for mid/hi-end (I'm thinking the classical rock wool ones you place spaced out a bit form the walls) and for the lower end, but I am very much open for suggestions. Here's some specs of my setup: - The room is roughly 3.60m wide, 3.40m long and 2.50m high. I think at least one wall is concrete. - My mixing position/monitors is in the middle of the front wall. I sit about 1.20m out from the wall. - My monitors are small, a set of Adam A3X (so 3" elements I guess). It basically gives very low bass response, so I can hear fairly OK down to about 80hz, rapidly declining down to 60hz where there's nothing left. - I am not terribly dependent on mixing at high volumes, if that matters. What I currently have is: - Two large bookshelves along the wall right behind my mixing position acting as diffusors. These go almost all the way up to the ceiling, and has stuff unevenly stacked at different heights/positions in the bookshelf. They cover 1.60m in the middle of the back wall. - I also have a fairly large carpet on the floor in the middle of the room. It probably doesn't do that much, but maybe it does a little. My question then is; are there any effective ways of acoustically treating this room? Of course, given the topic of the e-mail, I'm very much willing to do my own DIY solutions, if that's a viable option. What I have been thinking is doing what I mention above; classical absorber "panels", and bass traps. But, before I start anything, I'd very much like input from people who actually know what they're talking about (I'm looking at you on this list ;) ). So, does anyone have thoughts/suggestions for me? Any recommended way of doing this? Thank you very much for any help and any replies! -------------- next part -------------- An HTML attachment was scrubbed...

I have speakers in my music room and a second pair of speakers in my kitchen and walk around between both rooms, that are in a different way "horrible acoustically". Once I sit in a French studio lorry, it's possible to make unsuitable rooms very good control rooms. The first thing to make an unsuitable room a very good control room is to play the lottery. At least this French studio lorry was obscene expensive. IMO the best bet is to learn to accept that a home-studio in a flat has got a bad acoustic. Good luck!

Instead of an elCheapo near-filed monitor I use B 3010 HIFI consumer shelf speakers from former East Germany. They are often used as near-field monitors in Western Germany home-studios, small radio studios etc.. I got my for 50,-? at Ebay. They sound disgusting, but usually better than elCheapo near-field speakers in the price range of the Adam A3X. JFTR I don't know the Adam speakers, they might be good, anyway, Eastern Germany speakers are good HIFI speakers and they were made for small flats.

In-Reply-To: References: Message-ID: Gabriel, Check out the DIY page at ATS acoustics. For $72 I bought:Roxul Rockboard 80, Mineral Wool Board, 2 Inch (6PK) I built my own frames and covered with fabric from Spoonflower that I had custom printed with images of favorite musicians, so the 2x4 panels look like art. They are spaced 2" from the wall. The general rule of thumb is to stagger the panels and cover 50% of the space with absorbers. Sounds like you are almost there with the bookcase and carpet. I'd add a 6 pack of panels to the other walls and ceiling and go from there. Maybe add a good subwoofer. In my case I had a drum set against a live wall that I wanted to tame before going deaf! These did the trick. I have one drummer that plays really loud --- I' thinking of adding a few panels on the ceiling. Cheers!

Many years ago, we needed a sound booth at the tv station, so we put doors on both ends of a short 8' hallway between video production and the newsroom. Then we covered everything but the floor & gear shelves with Sonotex. It looks like egg cartons, but molded from a memory compounded acoustic foam. Fairly expensive for a wall covering, but gave us an instant acoustically dead room. And it lowered the background noise level in the room from the air conditioning etc, at least 20db. It glues on to install, and would be hard to get rid of the glue when you leave, probably requiring new drywall to clean up right. Landlords might not be the least bit impressed, so clear it with them first. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Here's some specs of my setup: I built some DIY floating panels suspended from the ceiling of my living room (to improve the acoustic environment in the TV/music/couch area). That part of the room is about 3.60m wide, 4.60m long and 2.60m high, so the dimensions are not too far off from yours. Maybe you'll find some of this useful/inspirational: I ended up building two big panels. each 3.00m x 1.20m. Each big panel is made from 5 smaller Troldtekt (http://www.troldtekt.com/) 1.2x0.6m acoustic panels. I went for the "Troldtekt Plus 75mm" variety, which consists of a 35mm thick layer of "wood wool" backed by a 40mm layer of mineral wool. The big panels are suspended ~0.25m from the (concrete) ceiling, by screw-in hooks and metal wires. Leaving some room behind the panels (as opposed to mounting them flush against the ceiling) improves absorption towards lower frequencies, and I still have ample height (~2.30m) below the panels. Also: suspending with wires means that I have the option of (re)moving the panels, leaving only 2 x 4 small holes to be spackled+painted. Some old, crappy pics from my phone here: https://www.dropbox.com/sh/xt2r8idaiqvhlld/AAD41vpxFRbDif_88uWk62Uva#/ Your usage (home studio as opposed to living room) means you'll likely need much more acoustic treatment than me.However, tackling the ceiling first, allows you to improve things a lot without giving up any "horizontal" space... ...Johan -- Johan Herland, www.herland.net From jeremy at autostatic.com Sun May 25 17:20:53 2014 From: jeremy at autostatic.com (Jeremy Jongepier) Date: Sun, 25 May 2014 19:20:53 +0200 Subject: [LAU] DIY acoustic absorbers?

Hello Gabriel, I recently borrowed a couple of A5X's and what struck me in the manual was that it only mentioned that you need a proper stereo placement and that the tweeters should roughly be at the height of your ears and that was about it. The chapter about placing the Yamaha HS50's I own myself is quite a bit longer, it mentions the minumim distance to the wall, that they shouldn't be placed in corners etc. I get the idea that the Adam's are not that picky and that they are ideal for mobile use. The guy I borrowed them from uses them in a mobile setup too in a great variety of environments that he barely knows beforehand (studios, cottages, rehearsal rooms, cellars, etc.) and he has had no big issues yet getting a decent mix out of them. What I wanted to say is that it might not be really needed to put a lot of time and effort in acoustic treatment. Unless if you clap your hands in the room you already know enough ;) Jeremy -------------- next part -------------- A non-text attachment was scrubbed...

If you look at the acoustical testing done on the various panel materials, you'll see it takes much thicker and denser material to have an effect on lower frequencies. I am far from an expert, this is just from memory when I researched the panels I ended up with. -Bob On Sun, May 25, 2014 at 2:25 PM, wrote: > On 05/25/2014 06:22 AM, Rob wrote: > > So, my question is about DIY acoustic absorbers. >> > > Bob Andres responds: "I built my own frames and covered with fabric from > Spoonflower that I had custom printed with images of favorite musicians, so > the 2x4 panels look like art.

In a homestudio of a friend we filled the corners with rockwool made a wooden frame and covered them with fabric. Early reflection points can be treated with 10-15cm thick "classical absorber panels". For our live room we've done something else, we made wooden slat covered frames and filled the cavity with rockwool .

I own a POD HD300, and I would like to use it as a sound card to loopback my guitar sound in the computer speakers...recording would also be nice. The POD gets appropriately recognized by the system and its device driver functions properly. In fact, I can hear sound using Pulse, of course with huge latency. I would like to use Jack for this (already properly installed and set it up for real time scheduling). I have configured Jack from QJackCtl such that the interface I am using is my POD (interface box in the Setup window - interface which is different than the one used in Pulse). Now, I cannot really go on. I guess I have two options to loop my sound back to the speakers (and please correct me if I am wrong): (1) specifying the input and output device in the Setup window appropriately; (2) specifying a proper connection in the Connections window. Option 1. The Input Device and Output Device scroll down list in the setup window are only usable if I select Duplex in the Audio scroll down list. And, in any case, they only list the audio cards of my PC, not the speakers. I guess, this is not the right way then. However I have some questions: what are the Input and Output device scroll down lists good for? And why can they only be used with duplex? Option 2. The POD appears only in the ALSA tab of the Connection window. Therefore I cannot connect it to loopback, which instead appears in the Audio tab. How can I proceed? And, in general, what is the difference between the three tabs Audio, Midi, and ALSA? Why don't I get the POD in the Audio tab as a USB sound card?

I do not really understand the logic of option 1 though. First, why are the input and output devices drop down lists shaded if I do not select duplex? In other words, if I only want to loop the sound back to the speaker, it does not seem that option 1 would work, as I cannot select the input not input device. And in any case, if I have already selected the interface I am going to use (my POD), what does it mean to select input and output device? As for the drivers. In fact I have not installed any driver myself. The POD gets recognized out of the box in pulse (doesn't it use ALSA too?). The first question is: if the problem was the driver, the device should not get recognized in the interface drop down list, right? But it is. Also, if I have a look at /proc/asound/cards, I get $ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xfcaf4000 irq 46 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfeafc000 irq 17 2 [PODHD300 ]: line6usb - POD HD300 Line6 POD HD300 at USB 8-2:1.0 As you can see, device number 2 is my POD, and strangely it says line6usb (which is the name of the device driver in sourceforge). Does this mean that the driver is there and that ALSA support the device? > Option 2. The POD appears only in the ALSA tab of the Connection > window. > > The ALSA tab in QJackCtl shows MIDI devices: the MIDI component of the > POD 300 is probably class-compliant (meaning, no special driver > required for that part).. Again, I do not understand the logic here. I am sorry, I am very new to these things. If the ALSA tab shows the MIDI devices, what does the MIDI tab show? Also, should my POD be listed in the Audio tab (if it was recognized properly)? Thanks again Cristiano -------------- next part -------------- An HTML attachment was scrubbed...

Does > this mean that the driver is there and that ALSA support the device? I'm a little surprised that you get something at all. I believe that the last working POD was the XT. I myself do have two X3s, one bean and one PRO, and they don't work on my systems. Beside that they do not work via USB in Linux, I don't consider this as a problem; I connect the X3 pro via balanced cables direct to the mixer the sound card if I want to and it's probably more noiseless than the "real thing". On the other hand: Maybe I should donate the X3 bean to someone that is willing to seriously try make the driver work again? I know that this isn't [LAD], but are someone interested? I'm not sure that I'm willing to pay to much of the shipping cost, but anyone?

However, I know there are some differences in numbering scheme for Jack depending on whether it's the SMP or non-SMP supporting version, and also there's the DBus versus daemon thing. My current Jack (before emerging) is SMP with DBus (it can be controlled with the jack_control comamnd). Should I be concerned about this?

And as such it requires a multilib-jack as dependency. The ebuilds from the pro-audio overlay have not yet been converted to multilib and this is why portage wants to downgrade your jack to the latest multilib version. In such a case I'd mask multilib version of fluidsynth.

The ebuilds from the pro-audio overlay have not yet been converted to multilib Let me correct this: The (masked) versions 1.9.9.5-r2 and 2.9999-r1 are multilib compatible. So instead of masking fluidsynth, you could unmask them.

There is a debian bug for this (Bug#681576) which includes the whole non series of stuff. It doesn't seem to have moved since 2012. Without packages it is unlikely that NSM will be "the" system. I, for one, hope someone (who knows what they are doing) will do the packaging... There is a whole group of people who will not use things till that happens. This is not meant to be fault finding (there is no fault to find), just pointing out reality. -- Len Ovens www.ovenwerks.net From len at ovenwerks.net Sat May 31 19:44:47 2014 From: len at ovenwerks.net (Len Ovens) Date: Sat, 31 May 2014 12:44:47 -0700 (PDT) Subject: [LAU] Session Management In-Reply-To: <538A3063.5090006@gmail.com> References: <20140529180215.GM13263@silverninja.net> <538A3063.5090006@gmail.com> Message-ID: On Sun, 1 Jun 2014, Ross Hamblin wrote: > On 01/06/14 03:15, Len Ovens wrote: >> On Sat, 31 May 2014, Harry van Haaren wrote: >>> >>> I would love to see NSM be used as "the session management" system, >>> and I've >> >> It would help if it managed to get packaged in debian (and other >> formats).

Yes, I am aware of the kxstudio PPAs and have in the past downloaded the non-apps from there. One of the problems I have had with doing that, is that the depends all point back to the same PPA set. This meant that almost my whole audio setup was replaced including jackd and some of the other session management tools. In fact one of them autostarted for me not when I started Jackd, but when I started one of the jack based applications. I am not sure this is a bad thing of itself for the end user, but for me this is not an option as I try to help people with UbuntuStudio set their system up and it helps if I can shadow what they are doing with the same versions of application. I also do not know what the current set of kxstudio apps are like. They may have changed and my comments may well be out of date. Generally good quality stuff anyway. -- Len Ovens www.ovenwerks.net From chris at chriscaudle.org Fri May 30 16:43:23 2014 From: chris at chriscaudle.org (Chris Caudle) Date: Fri, 30 May 2014 11:43:23 -0500 Subject: [LAU] HDMI connected small system with multi-ch outputs? Message-ID: Do any of you working with the small (typically ARM) systems that have HDMI output know of such a system which has ALSA supported multi-channel HDMI output? All I have found so far have two channel ("stereo") HDMI output only. Bare assembly or packaged in a case is OK, I'm not picky. I'm not planning on using the video for much, so closed source video is OK as long as the HDMI audio is at least 6 channels and has an ALSA driver. -- Chris Caudle
