There was a 0.35 version that had been patched to support non-interleaved mode IIRC. Maybe you can try to use the card through the plug layer, but performance will be suboptimal. Thomas

Check with "fuser /dev/snd/pcmC0D0c" or similar. With Pd however a lot of people have problems using the RME cards directly. You may be luckier if you use Pd over Jack. Otherwise try to not use Pd's default device hw:0 when starting Pd but maybe use plughw:0 first or define a device in your ~/.asoundrc, that matches your favourite setup. Pd 0.37.1test6 now has the "-alsaadd" option to let you specify arbitrary PCM names. ciao -- Frank Barknecht _ ______footils.org__

Am I expecting too much? Do you have /tmp mounted in ram? If not, add this to /etc/fstab and reboot: none /tmp/jack tmpfs defaults 0 0 Austin I had "none /tmp ramfs defaults 0 0". It was shown this way on Thacs website I think. But an error would pop up on boot. I just added the lines you suggested without the /jack directory. Version of Jack I'm using places files in "/tmp". No "/tmp/jack" there. Will see if any improvement. thanks

I wouldn't recommend using a non-mandrake kernel on a mandrake system... we have lots of necessary patches in there. Was there a problem with the multimedia kernel from 9.2? Auston, I only assumed the packaged mandrake MM kernel was Andrew Morten's...I installed the MDK multimedia RPM kernel from Thac's RPM's for 9.2. It installed fine and boots from Lilo...as to if there's anything wrong with it...I don't know. How can I tell if it is fuctioning properly with scheduling and such? R~

[linux-audio-user] zipper noise during playback

by Dave Phillips

Greetings: I've already written to the usual lists about this problem, but as yet I've read no solution. During playback of audio in JACK apps (Snd, Ardour, SC3) the sound wil often start out fine but after a few minutes it begins to distort in a "zipping" fashion, like it's out of sync with itself. After a few minutes it returns to stability. It's starting to be a real problem for me, so I thought I'd ask here again if anyone else has experienced this problem and what did you do to fix it. Here's the system: Planet CCRMA RH 9 w. kernel 2.4.24-ll ALSA 1.0.1 JACK 0.94 SBLive Value gForce2 w. nVidia driver XFree86 4.3.0 The machine is no screamer, an 800 MHz Duron, but I haven't had this problem with it before. I have suspicions about the nVidia card and driver, and I'm also wondering about moving the SBLive to another slot. Any and all advice on this problem will be vastly appreciated. Btw, I don't have the problem during playback from XMMS or xine. Best regards, dp

[linux-audio-user] Links for 'Made with Linux' music

by Daniel James

Hello all, On the GNU/Linux Centre stand at Sounds Expo 2004 (London, 10-12 Feb) I'm planning to take along a laptop with some DJ software, and I was going to take my typical DJ set music with me. But - I thought - why not take some 'Made with Linux' music instead! Apart from our own stuff, I'd like to take along as much music made by the community as possible. So please send me links for your oggs and mp3s, offlist if you like - any genre is fine. Cheers Daniel

[linux-audio-user] Noob...Latency, Mandrake and Dell questions...

by Russell Hanaghan

Hi folks, I have been using Linux for about 2 years now. Started with MDK 8.0 and have mostly stuck with them. Using 9.2 now.I'm not a command line expert at any measure. In fact, if not for the vast improvements in the GUI I would not have the time to get anywhere with linux. I started awhile ago hunting around for audio apps spured by Austin Acton's "Mandrake 9.1 Audio workstation how to" advertised in the Mandrake emails. I figured out how to setup URPMI and found apps like Jack, Ardour (Since, like 8 releases ago) Rosegarden, Fluidsynth and a vast surprising variety of other cool audio stuff. I thank "Thac" for his efforts on the "Thac's RPMS" pages as he keeps the Mandrake packages for the audio stuff up to current release more than any other repository I've found.(I never seem to have much success at building from source). Anyway, my biggest headache is getting my laptop fine tuned to work at it's best with Linux Audio under Mandrake. I have used Win XP and Cakewalk Sonar since its release and I get fairly solid performance out of it. I use it live for it's midi playback capabilities. (Save midis to Sonar format maintaining mix, edit data easily, etc.) I would one day like to use Linux instead but "Live" is where the rubber meets the road! Cant afford to have crashes and glitches in the middle of a show. I also use Sonar for recording. As promising as Ardour is, I just dont have the time to figure out everything. Sorry if that seems non contributing but it's just the way it is. I can promise that when it is sorted, I WILL pay/contribute financially to have it, if it meets my needs. Sure would like to see the inbuilt midi capabilities in it. But I know the focus is on the general recording and editing side and thats cool. Must be a lot of work! I want to try using a spare laptop for live fx processing (Over vocals on a PA)at this point. Some of the LADSPA plugs seem very cool (Gverb for one) and I can get Jack-realtime working but dont know if it's working as good as it could. I have been messing with Ecamegapedal with Jack. So heres my stuff: Dell CPxJ 650mhz, 256megs Ram, 20 gigHD (5400RPM I think) I installed Andrew Mortens(??) Multimedia kernel RPM and it boots fine...although I dont know where the scheduling is sitting or if it is even making a difference. The Dell Latitude has a Maestro3 PCI audio accelerator chip. (Not real high end I know but works sufficiently well with Sonar XL) If I set Jack parameters in Qjackctl any lower than 1024 I get Xrun mayhem. (at 44100) I have also tried this running from consoles as root and it does not seem to make much difference. Am I expecting too much? Anyway, sorry for such a long post but I was told in the Ardour users list that this was where I should ask all this stuff... I do luv linux (it's kinda addictive) and would like to completely sever the umbilical from Bill someday. :) thanks for any help in advance.
