JACK 0.92.0 has been released. Mostly minor changes: * allow `jackd' to belong to a non-root group * new ./configure option, --disable-ensure-mlock - allows JACK and its clients to run in realtime mode without having memory locking privileges. - default behavior same as before (--enable-ensure-mlock), JACK clients terminate if running -R and unable to lock memory. * option parsing bugs fixed. * correctly handle deactivate/activate sequence for: - slow-syn callback - timebase callback Jack can be downloaded at http://jackit.sf.net .

I'm not too concerned with the 2.6.0 kernel. I'm more interested in the 2.6.1 kernel after Andrew Morton has merged his patch set into the official kernel. Does anybody know what type of effect, if any, his patch set has on multimedia work? -Reuben

My experience with 2.6, and also the impression I have got from reading linux-audio-dev, is actually the opposite. The 2.6.0 kernel is worse for multimedia work, because the latency is higher than 2.4.0 with the low-latency patch. I don't know mathematical that this is correct, but it seems so. Hopefully it is possible to make a low-latency patch for the 2.6 kernel as well? --

Re: [linux-audio-user] Cooledit substitutes?

by Juhana Sadeharju

>From: r7 <r4nd0m7(a)yahoo.com> > >Apologies for interrupting with a rather basic >question. But that kind of questions reveal what we are missing. It could be better you to continue using Cooledit. I use Audacity nearly daily and would use it more if it would not miss some features. Audacity and Rosegarden have quite bad audio engines: Audacity freezes completely if one has several tracks (even if only one track is soloed), and Rosegarden skips segments and plays segments at wrong speed. I would not go to any exhibition and show Linux audio yet. Good luck for you who do that. I'm quite critical user (if pointing out malfunctions can be called "critic"), so, if anyone of you developer would like to have my feedback on your software, please let me know. I will install latest version of your software and will tell what happens and what I experience. Maybe such a feedback could lead to a better software. I cannot myself go and fix 20+ Linux audio software even I would like to do that. Regards, Juhana

[linux-audio-user] USB Audio Problems

by Mark Williams (MWP)

Hi all, Has anyone else been having USB audio device problems with the 2.6.0-test kernels? I have the ALSA USB audio driver enabled, as well as the normal USB audio device driver (in the USB section). On plugging on the device i get the output below. If i then try and use the /dev/dsp device supplied, the app trying to play to it locks up (even a kill -9 wont make it go away). The USB device is based on the texas instruments PCM2902. Here is the dmesg dump: hub 1-0:1.0: new USB device on port 1, assigned address 2 usbaudio: device 2 audiocontrol interface 0 has 1 input and 1 output AudioStreaming interfaces usbaudio: valid input sample rate 48000 usbaudio: device 2 interface 2 altsetting 1: format 0x80000010 sratelo 48000 sratehi 48000 attributes 0x00 usbaudio: valid input sample rate 48000 usbaudio: device 2 interface 2 altsetting 2: format 0x00000010 sratelo 48000 sratehi 48000 attributes 0x00 usbaudio: valid input sample rate 44100 usbaudio: device 2 interface 2 altsetting 3: format 0x80000010 sratelo 44100 sratehi 44100 attributes 0x00 usbaudio: valid input sample rate 44100 usbaudio: device 2 interface 2 altsetting 4: format 0x00000010 sratelo 44100 sratehi 44100 attributes 0x00 usbaudio: valid input sample rate 32000 usbaudio: device 2 interface 2 altsetting 5: format 0x80000010 sratelo 32000 sratehi 32000 attributes 0x00 usbaudio: valid input sample rate 32000 usbaudio: device 2 interface 2 altsetting 6: format 0x00000010 sratelo 32000 sratehi 32000 attributes 0x00 usbaudio: valid input sample rate 22050 usbaudio: device 2 interface 2 altsetting 7: format 0x80000010 sratelo 22050 sratehi 22050 attributes 0x00 usbaudio: valid input sample rate 22050 usbaudio: device 2 interface 2 altsetting 8: format 0x00000010 sratelo 22050 sratehi 22050 attributes 0x00 usbaudio: valid input sample rate 16000 usbaudio: device 2 interface 2 altsetting 9: format 0x80000010 sratelo 16000 sratehi 16000 attributes 0x00 usbaudio: valid input sample rate 16000 usbaudio: device 2 interface 2 altsetting 10: format 0x00000010 sratelo 16000 sratehi 16000 attributes 0x00 usbaudio: valid input sample rate 16000 usbaudio: device 2 interface 2 altsetting 11: format 0x80000040 sratelo 16000 sratehi 16000 attributes 0x00 usbaudio: valid input sample rate 16000 usbaudio: device 2 interface 2 altsetting 12: format 0x00000040 sratelo 16000 sratehi 16000 attributes 0x00 usbaudio: valid input sample rate 8000 usbaudio: device 2 interface 2 altsetting 13: format 0x80000040 sratelo 8000 sratehi 8000 attributes 0x00 usbaudio: valid input sample rate 8000 usbaudio: device 2 interface 2 altsetting 14: format 0x00000040 sratelo 8000 sratehi 8000 attributes 0x00 usbaudio: valid input sample rate 11025 usbaudio: device 2 interface 2 altsetting 15: format 0x80000010 sratelo 11025 sratehi 11025 attributes 0x00 usbaudio: valid input sample rate 11025 usbaudio: device 2 interface 2 altsetting 16: format 0x00000010 sratelo 11025 sratehi 11025 attributes 0x00 usbaudio: valid input sample rate 11025 usbaudio: device 2 interface 2 altsetting 17: format 0x80000040 sratelo 11025 sratehi 11025 attributes 0x00 usbaudio: valid input sample rate 11025 usbaudio: device 2 interface 2 altsetting 18: format 0x00000040 sratelo 11025 sratehi 11025 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 1: format 0x80000010 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 2: format 0x00000010 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 3: format 0x80000040 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 4: format 0x00000040 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 5: format 0x80000008 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: valid output sample rate 32000 usbaudio: valid output sample rate 48000 usbaudio: valid output sample rate 44100 usbaudio: device 2 interface 1 altsetting 6: format 0x00000008 sratelo 32000 sratehi 48000 attributes 0x00 usbaudio: registered dsp 14,3 usbaudio: constructing mixer for Terminal 2 type 0x0301 usbaudio: registered mixer 14,0 usbaudio: constructing mixer for Terminal 5 type 0x0101 usbaudio: no mixer controls found for Terminal 5 usb_audio_parsecontrol: usb_audio_state at cbfbd4e0 drivers/usb/input/hid-core.c: ctrl urb status -75 received usb 1-1: control timeout on ep0out Thanks for any help.

[linux-audio-user] Re: some notes regarding sync (JACK, MTC) under Linux

by David J. Kuntz

I tried to duplicate the distortion w/ Hydrogen & Ardour, and couldn't. It happened consistently at the end of the first play-through of the song. What version of Hydrogen are you using? I upgrade to 0.8.1 last night.

I'll give it a shot tonight.

[linux-audio-user] linux kernel 2.6.0

by aguerrier

Hi What sort of improvements are we(linux-audio-users) to expect upon upgrading the kernel of our DAW to 2.6.0? I am asking the question to get some knowledge and start a nice discussion. I have read 'The Wonderful World of Linux 2.6' on http://www.kniggit.net/wwol26.html There is a nice paragraph on 'audio and multimedia'; it mentions ALSA's inclusion in the kernel and improvements in USB Audio and MIDI devices and some upgrade in Video4Linux subsystem, as well. What does it all mean to our day-to-day productivity? Should I now get the M-Audio Firewire 410, because its functionality might/probably have improved? Any thoughts? Adler

[linux-audio-user] Terratec EWS88MT (envy24) problem

by Ben Cochez

Hello, I have a Terratec EWS88MT soundcard, and I want to control it via a console interface. Many users with this card use the envy24control program (which does it job) but that's no option for me since X is not available on that machine... Alsamixer lists all the channels, but has some problems outputting sound to all the eight channels. If I send some signal to all the eight channels i'm only getting sound output on two or three of them... I'm using v0.9.8 of the libraries, drivers and utilities. I've tried aumix, but that mixer doesn't show the channels I need... Any advice what to do next? Thanks! Ben

[linux-audio-user] keyboard falls asleep

by Jaakko Prattala

Hi. I'm trying to get my multiface to work with my laptop again. I've gotten to a point where I can start jackd and it seems to run ok except that ~2 seconds after it starts, my keyboard goes numb with pc_keyb: controller jammed (0x15) or pc_keyb: controller jammed (0x35) This is not the only situation where this has happened. Things got a lot better when I switched to another driver for my graphics card. I know this is not strictly audio-related but maybe someone has similar experiences and can help? -- Jaakko
