[linux-audio-user] Re: hdsp pcmcia issues, again...Someone please explain this phenomenon?!!

by we are

ok, so i'm still stuck and still hanging around bothering people with this desparate issue, sorry.. just found this really really weird thing whilst fiddling with my HDSP multiface(pcmcia) and really like some kind of explaination for is so that it may help me and my hdsp issues. so i'm an avid PD user and i was having a poke around trying some things out. i am getting a horrible distortion with all sounds that output the card and i have been testing with a sine tone in PD to troulbe shoot this. i read in the rme FAQ's that it is suggested not to have the HDSP as the primary and default card in windows as the HDSP gets its sync from other devices. i assume that this is very different in linux and moreso JACK although i don't exactly know how. anyway, i tried running two intances of PD one with the IntelAC'97 (intel0x8) onboard card and the other instance of PD with the hammerfall hardware. This was done though ALSA and not JACK btw... the really weird thing was that the sine tone played perfectally through the multiface! whats up with that?!! however, i have noticed(and this is the main reason fro getting onto the HDSP) that the sine tone that the intel0x8 card plays is full of clicks and DIO errors from pd. when i get the tone out of the multiface using this technique, it is the exact same quality tone clicks and all. so what i can see is happening here is that for some reason, the sound is routing through the intel0x8 card into and out the multiface. this only happens with pd and all other applications function (or not) normally ie, with a horrible distortion out the multiface. could someone please explain to me what the **** is going on? and could this phenomenon help my situation at all. thanks tom On 3/8/06, we are <gateswideopen(a)gmail.com> wrote: > hi crew, this issue is probably getting boring now but i've hit it. > > i am trying to get my Multiface PCMCIA card to work under linux and > have tried many things but still a bit lost. i have it running on my > windows setup on the same computer(another partition) without a hitch. > for this reason i can't understnd why it would not function here in > linux. > > i am running an Asus v6800v (v6v) laptop and would really appriciate > some advice on where to move next... > > i have reached the point where alsa is set up > > ..... > > localhost tom # cat /proc/asound/cards > > 0 [DSP ]: H-DSP - Hammerfall DSP > > RME Hammerfall DSP + Multiface at 0x54000000, irq 17 > > 1 [ICH6 ]: ICH4 - Intel ICH6 > > Intel ICH6 with ALC650F at 0xdffff800, irq 17 > > ..... > > lspci | grep CardBus; lspci | grep RME > > 03:01.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev b3) > > 04:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall > DSP (rev 32) > ..... > > uname -a > > Linux localhost 2.6.14-gentoo-r5 #1 SMP PREEMPT Tue Jan 17 05:35:27 > EST 2006 i686 Intel(R) Pentium(R) M processor 1.73GHz GenuineIntel > GNU/Linux > > ..... > > i have tried using setpci latency scripts found on this thread http : > lists.infradead.org/pipermail/linux-pcmcia/2004-April/000750.html > > However, i must admit i'm a really lost when it comes to this level of > computing. so i'm stabbing in the dark and currently trying to learn > about what all this means. > > script written by Daniel Ritz > > > #!/bin/sh > > > > > > # set lateny timers for the bridges > > > CB=`lspci | grep CardBus | cut -d" " -f1` > > > for i in $CB; do > > > echo "setting latency timer for CB $i" > > > setpci -s $i 0x0d.b=0xff > /dev/null > > > setpci -s $i 0x1b.b=0xff > /dev/null > > > > > > # for EnE only, others should ignore it > > > setpci -s $i 0xc9.b=0x06 > /dev/null > > > done > > this script did something but i'm not entirely sure what?

[linux-audio-user] Debian and friends

by Lee A. Azzarello

Over the last few days I've been having quite a few problems with Debian stable and jack applications. I don't want to run sid or etch because I like to work with stable libraries and a base system. I'm comfortable doing backports and building packages myself. But lately I have been building so many packages myself I'm begining to feel like I'm making a little mini distro in my local apt repository. This got me thinking about potential alternatives to running sarge. So If you'll humor me for a minute, I'd like to take a little poll. This only concerns users/developers of real Debian and variants that pull from the official archives. 1) What Debian communities for audio software packaging are you a part of? 2) How do you install new releases to your system? 3) How often do you build your own kernel for audio systems? 4) If you're not running real Debian, what made you change? 5) If you are running real Debian, have you upgraded to etch or sid? I'll start by answering my own questions: 1) Not many. I'm looking through alioth and see some interesting projects but they have no notice of a package repo and the mailing lists are full of spam. 2) I usually don't. If I need to I'll try a backport, though this is failing with the version of jackd in sid. I don't know why. 3) I try not to as much as I can. Kernel compiling is a waste of time unless absolutely necessary for device support. I find myself compiling kernels for sound more than any thing else (video, web services). 4) I'm running sarge, eagerly awaiting etch. Thanks for your time... -lee

[linux-audio-user] Totally OT (was Rhythm Galaxy vol.1 drum/percussion sample library)

by Maluvia

I assume, (perhaps erroneously), the following things: 1. Everyone, unless they are independently wealthy, living on a pension, or a hobo, has a job or self-employment income by means of which they are enabled to pay their bills and purchase the goods and services they either require or simply desire. 2. All said individuals are actually being *paid* a wage, salary, or receiving some form of income for this work - else they could not pay the rent with it, so to speak. 3. All these same individuals believe they *deserve* to be paid for whatever work they do for their employer - or if self-employed - for whatever goods or services they offer for sale. This being the case, how on earth can such individuals make the case that they deserve to be paid for what they do for a living, while an artist, programmer, or individual in some line of work other than their own - does not? Just asking. I find the degree of hypocrisy underlying such a premise utterly dumbfounding - not to mention the conceit. - Maluvia

Emulation for the sake of emulation is pretty much the opposite of creativity, which is what we are trying to promote here, right?

I think it is so cool when people post a drum track and say, "Could someone add a bass track to this? I'm no good at bass..." Or maybe define a general direction and mood for the song to go into, and whoever wants to get on board is welcome. Then you would have musicians who actually _want_ to play this music helping out with the recording of a song. I think there is already a place where we can do this, though... It's called the Linux Audio Users Group. ;-) -Tim

[linux-audio-user] Blue snoball USB mic

by Lee A. Azzarello

The thread about the Griffin iMic got me thinking about the Blue Snowball. Has anyone got this mic: http://www.bluemic.com/modules.php?op=modload&name=Products&file=index&prod… working on GNU/Linux on any archetecture? I'm piecing together a wireless portable internet radio system and the mic preamp is the bottleneck. I can't find a decent battery powered mic preamp to talk to Jack. This model looks like a step in that direction. -lee

[linux-audio-user] Re: Marketing Free Music

by Juhana Sadeharju

I would these requirements: -One place (with mirrors) to download the songs. -Easy download of huge number of songs. -No limitations on the download amounts. -No registration required. -No any closed-source upload/download software. -The downloaded songs can be copied to other free songs places. -*- Many services rely on individual downloads and, worse, on registrations. These services have thousands of files which must be downloaded individually with a few button clicks each. If I wish to have a complete collection (and why wouldn't I), I certainly would break my mouse hand. Downloading 1000 songs with "wget -r" and playing the songs with "ogg123 *" saves much of the selection trouble as well. -*- If musician choose to place their songs available at their own webpages, then the license should allow us to copy the songs to the free songs places.

If the musician with the "vision" were in control of what was put into the mix, I think it could function as a sort of a CVS system, with one or two artists coordinating the efforts of many musicians! Then there could be beta releases, etc, saying "OK, here's what we are working from now."

[linux-audio-user] Free Music Factory

by Juhana Sadeharju

I have this idea: We could have an organized community where volunteer musicians make music similar to the top commercial songs. When the idea works, one may get top pop music for free. -*- Making similar music purposedly is nothing new. Many top commercial songs generate a row of similar commercial songs which then end up to the top as well. We need this kind of alternative way of making free music. For example, the recent free music CD announced here at LAU simply sucks. I don't know why. -*- As how to organize the Free Music Factory, we need volunteers: singers, lyrics authors, musicians of different styles, etc. We also need volunteers who know technical details: effects, cool synth sounds etc. The commercial songs need to be musically analysed as well.

[linux-audio-user] A proposal

by james＠dis-dot-dat.net

Hello all. I've been busy and off the lists for a while and will be for a while, but I just wanted to pass on something that could be very useful/important. Please don't stop reading when you read "Microsoft", "scheme" or "money". I'm not asking for bank details :) There is a scheme for lecturers/researchers working in computer science and its various flavours in developed countries in the EU and USA to travel to developing countries for research or teaching. Microsoft will put up the travel money if the hosting institution will cover living expenses. I think they will supply up to 1,300 pounds. It works a bit like on-line dating - people that want lecturers/researchers sign up, as do lecturers and researchers. Then you see if there's a match and take it from there. So, if you're a lecturer or researcher that feels like taking you skills into developing countries for a week or two, take a look. Also, if you're from an institution in a developing country and would like to have a visiting lecturer/researcher, sign up. You might think this is totally the wrong place (actually, I cross-posted so I should say "places"), but here are my reasons: 0. I know there are a few lecturers/researchers on the list. 1. Very few people have signed up due to poor advertising. This means the money could just not get spent when it could do some real good. It also means that any potential collaborations are very likely to get funded. 2. Microsoft is probably the least favoured company on these lists BUT think of this as a way to get some of their ill-gotten gains spent doing something good. 3. It really does look like a good deal. I can't see any reason to suspect Microsoft are doing anything evil on this one. I'm going to sign myself up - why not join me. Details: http://research.microsoft.com/ero/icd/inspire/ Feel free to ignore this mail, but I'd appreciate not getting flamed ;) James -- "I'd crawl over an acre of 'Visual This++' and 'Integrated Development That' to get to gcc, Emacs, and gdb.
