[linux-audio-user] ams, jackd & X as root? on debian

by Eric Dantan Rzewnicki

hello, I have jack installed and working now. So, now I'm trying to get AlsaModularSynth compiled and running. Has anyone else accomplished this in debian stable (woody)? I installed libqt3-mt (along w/everything it depended upon), fftw-dev, fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to edit the top of make_ams to agree with the location of the qt3 libs, bin and include directories on my system as best as I could figure ... but I'm not sure I got it right: QT_LIB_DIR=/usr/lib/qt3/plugins/styles QT_BIN_DIR=/usr/share/qt/bin QT_INCLUDE_DIR=/usr/include/qt it seems to compile OK when I do: make -f make_ams though there are a lot of warnings about comparing signed to unsigned and other warnings that flew by. Are these benign? Anyway. I end up with an executable ams. When I run ./ams I get this: ./ams: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory I have that in /usr/local/lib/libjack.so.0 so creating this link appears to help: box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0 Is that the correct sollution? but, now: box1:/home/eric/audio_code/ams-1.5.5# ./ams ams: cannot connect to X server I assume this is because X is running as me (eric) and not as root. I'll try getting out of X and starting it as root as soon as I finish writing this message. But, is there a way to let root connect to the X server that's running as eric? I was sort of ok (well, not really, but I'm giving it a try) with the idea of running jackd and its clients as root ... but, running X as root, too? that makes me more nervous, somehow... maybe I shouldn't be nervous about that ... I'm not sure. anyway. i'll give it a shot with a root X session. I'm thinking that maybe I should patch and recompile the kernel and recompile jack to enable capabilities so I don't have to run as root. Do those of you running jackd as root also run your X session as root? Thanks for listening, Eric Rz. PS If all of this has been covered before and my questions are annoying you, feel free to send me to the archives. I try to follow jackit-devel, but most of it seemed to go over my head before I actually started to try it. So, re-reading the past couple months would probably do me some good now that I have the real thing in front of me. -edrz

by Joshua N Pritikin

i got my new Audiophile 2496 installed with Alsa 0.9.0rc5. i have an external A/D converter and the SPDIF light is lit, meaning that the card is working. alsamixer shows *lots* of controls. What do they all do? Can someone post a working /etc/asound.state? -- Victory to the Divine Mother!! after all, http://sahajayoga.org http://why-compete.org

[linux-audio-user] Planet CCRMA

by Jlawrence＠tacenergy.com

I've just downloaded the planet ccrma materials and I will be installing them over the weekend. I'm curious about the applications contained in the package: 1. Is there a way to just install everything in one swoop, or do I have to rpm -Uvh xxx.rpm every time on all packages? 2. What about packages (movie and sound players come to mind) that already exist in some form in a standard RH 8.0 install? Will installing over them confuse the situation? 3. I'm doing this on a Dell Laptop. Am I doomed to failure? Thanks, Josh Lawrence

[linux-audio-user] [ANN] swh-plugins 0.3.4

by Steve Harris

http://plugin.org.uk/releases/0.3.4/ Hods of changes, including: * Bugfixes to GSM sim (Pascal Haakmat) * Bugfixes to FM osc (Pascal Haakmat) * Bugfixes to audio divider (Nathaniel Virgo) * Added another compressor, SC4, stereo, no sidechain * Added lookahead brickwall limiter * Added L/C/R delay (requested by Marek Peteraj) * Added Giant flanger (kind of requested by Patrick Shirkey) * Added DJ Flanger (actually requested by Patrick Shirkey) * Should now compile on FreeBSD * Fixed syntax error in RDF metadata, works with Bob H's jack-rack now I've updated the AUTHORS list, but I've undoubtedly forogtten people, so if youre not in there and should be give me a shout. SC4 is more-or-less like SC3, but has no sidechain and a subtly different algorithm. The sidechain was confusing hosts. The limiter has up to two seconds of lookahead, so can be very gentle. The L/C/R delay might be a bit familiar to Korg Trinity users ;) I haven't used it much bet it seems pretty cool. The giant flanger was a mistake, but I left it in anyway. The DJ flanger hjas controls for LFO period (instead of frequency as you would have in a synth) and you can resync the LFO by clicking a toggled control*. - Steve * This reminds me, there would be a use for a MOMENTARY hint (implying or requiring TOGGLED) in LADSPA, that meant that a control port should only be held high while the UI control was held down, otherise you have to double click reset controls, which is confusing.

[linux-audio-user] using jack-rack as real time effects processor.

by jordan muscott

Greets all, I've got a nasty feeling I'm doing something stupid here, but i'm fed up of doing it on my own. sound blaster pci 128 ( ens1371 ) alsa0.9rc1 jack 0.44.0 I want to use jack-rack as a real time effects processor. The first thing i'm not entirely comfortable about is that whatever audio I send to the IN on my soundcard seems to get sent straight to the OUT ( i can record stuff ok ). Then i'm starting jack: [root@larry jordan]# jackd -R -d alsa -d hw:0 and the starting jack-rack ( as root, of course ). I've tried using the -o -i options here too. I get the following from jack_lsp: [root@larry jordan]# jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 I've tried making what seemed like the sensible connections here with jack_connect, but the sound i'm sending in either just gets echoed to the output ( as per normal ), or I get hideous feedback. Somebody, please help. Thanks, Jordan.

[linux-audio-user] MDK Survey Results

by Austin Acton

First, thank you all very much for your answers. I can't believe the response... a lot of great ideas in less than 24 hours. If anyone else has ideas, please let me know, as the project is far from over. The developers' mailing list at Mandrake is buzzing with audio talk now. :-) Here are the major complaints about Mandrake 9.0 in general, with comments. Where applicable, I will forward the suggestions or problems to the appropriate developers at Mandrake. 1. Supermount problems in 9.0 This is well known. This month a few people have been patching up supermount for 9.1. As for 9.0, most people find the problems tolerable, but you can easily disable supermount on afflicted drives by editing 'supermount' out of your /etc/mtab and /etc/fstab files. 2. Desire for unpatched kernel Mandrake has always included an unpatched version of the kernel. It is called kernel-linus rather than kernel, and is not installed by default. You can install it with # urpmi kernel-linus 3. Problems with alsa sound quality on certain devices If these are alsa-specific problems (occur on other distros), please report them to alsa-project.org. If they are Mandrake specific, it would be nice if you could test the 9.1beta2 release to see if we have fixed it yet. If not, please report to http://qa.mandrakesoft.com. 4. Drakx (our installer) too simplistic With most new distros tending toward MORE simplistic installers, I have a hard time understanding this. Try expert mode first. If that's still too simple for you, you're welcome to make suggestions at mailto:cooker@mandrakesoft.com our developers' mailing list. We have added a rudimentary sound card and sound system (alsa/oss) configurator in the Mandrake Control Panel, so you can change sound system and card quite easily at any time. 5a. Drakx doesn't detect/configure USB audio Pixel, the mastermind behind our installer was very surprised by this. He says if you send him your /proc/bus/usb/devices list, he will fix the problem. The exception is the Extigy. Currently it's not detected, and they're not sure if we can include the drivers for it. 6. Drakx installs too much by default I assume this is to help new users get a semi-complete distro in one step. As you mentioned, the alternative is to select no "categories" of packages, and select packages individually. We offer both methods. 7. No low latency patch Currently we have a mini-low latency patch in our main kernel. I 'think' we are waiting for the rest to be officially incorporated into the main kernel, but I'm not sure. I'll ask. A fully patched low-latency kernel has been available on the Mandrake Club website for 8.2 and 9.0 for some time now though. Not sure if it will be default in 9.1 or not. I hope so. 8. Libraries and header files are in separate RPMs and must be installed separately We do this because the average user doesn't need header files and they take up extra space. It is not true that they must be installed separately though. If you urpmi the -devel package, the library package will be installed automatically, but not vice versa. 9. Can't run jack unless root I don't know much about this, or whether it's true or not in 9.1. I've asked some people to look into it. Could someone tell me what commands they would like to execute but can't? Now for requested applications. To my surprise, most of these we do not include. I will do my best to get most of them included in 9.1. Some others we already include, or can't include. I'll comment below. Requested that we include already: snd mplayer Requested that we can't include: cinelerra (includes mp3 encoder) lame (ditto) both may be available at plf.zarb.org, a site run by outlaws :-) realplay (proprietary, available at www.mandrakeclub.com) Requested that we don't plan to include: broadcast 2000 (obsolete, hard to maintian) Requested that I know Tobbe is working on currently: ardour qjackconnect csound cecelia rtsynth swami muse pd ceres vkeyb all are available for Mandrake 9.0 at: http://rpm.nyvalls.se/sound9.0.html but are completely unsupported They will be in 9.1 for sure. Requested that I will personally look into: kaconnect amsynth spiral* (won't compile with gcc 3.2.1, will need to ask author to fix) freqtweak jmax seq24 Finally for favorite apps. I wanted to know what apps we should focus on, as well as estimate how well we are doing at including popular apps. Favorite apps we include: 56% of votes Favorite apps we don't include (yet): 38% of votes Favorite apps we can't/won't include: 6% of votes So it looks like we're not doing too bad! Looks like 9.1 could include 94% of your favorite apps. I really want to thank you all again for your help. Mandrake 9.1 should be released in April. Until then feel free to ask questions, pose suggestions, and submit bug reports. I will be on this list indefinitely I hope, as I'm a heavy Audacity user. :-) Austin -- Austin Acton Hon.B.Sc.

[linux-audio-user] Using Audigy 2 in Linux

by Carles Barrobes

Hi all, I'd like to know whether someone has succeeded using Audigy 2 under Linux. I'm using the latest emu10k1 driver downloaded from soundforge (v0.20a) on a Mandrake 9.0 with ALSA 0.9rc2. The driver seems to be sending analog audio output to a digital out only jack that results in the audio signal coming out from there totally distorted. No sound is coming from analog outputs. I can't manage to get it to send the signal to the right analog output. I have 5.1 analog speakers. Anyone out there that has managed to make this setup work will be welcome to enlighten me. Hint: the Audigy 2 is slightly different from Audigy (1) which does seem to use the jack labelled digital out for both analog and digital output, depending on setup. Probably the driver as-is works with Audigy. I'm looking specifically for Audigy 2 users. Thanks a lot in advance, C A R L E S

[linux-audio-user] MDK audio distro survey

by Austin Acton

Hello all, I'm a major contributor and volunteer at Mandrake, and I've been working to get Mandrake up-to-date and more complete with regard to audio applications, so I thought this would be a good place to come for advice. If you have a few minutes, please answer any of the following questions you can. Doing so will help make Mandrake 9.1 the best audio distribution on the planet... 1. If Mandrake 9.0 is your primary distribution for audio, what is your #1 complaint? 2. If Mandrake 9.0 is not your primary distribution for audio, why not? What is missing or what has turned you away? 3. What audio applications are we missing (please check current list provided below, as many new apps have been added since 9.0)? 4. What thee audio applications do you consider the most valuable/important? (do not include alsa, jack, mixers, or ogg/mp3 players/encoders) Thanks very much. I appreciate your time, and please let me know personally if there is anything else I can do to make Mandrake more audio-friendly. Austin -- Austin Acton Hon.B.Sc.
