After I upgraded to Linux 2.6.13(-r5) and alsa-lib and alsa-tools-1.0.10, jackd gives no output any longer. jackd seems to successfully connect: jackd 0.100.7 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Note: audio device hw:0 doesn't support a 32bit sample format so JACK will try a 24bit format instead Note: audio device hw:0 doesn't support a 24bit sample format so JACK will try a 16bit format instead nperiods = 2 for capture Note: audio device hw:0 doesn't support a 32bit sample format so JACK will try a 24bit format instead Note: audio device hw:0 doesn't support a 24bit sample format so JACK will try a 16bit format instead nperiods = 2 for playback And jack clients can connect to jackd, too, but none of the clients does produce any output. With Kernel 2.6.14(-r2) the problem persists. Before upgrading, everything worked a charm. I even tried to remerge alsa-lib, alsa-utils, jack-audio-connection-kit and the related jack-clients (amSynth, fluidsynth and a few more in my case), but got no positive results.
jackd -d oss (= alsa oss emulation) still works btw...
Are you using alsa-driver or in-kernel drivers?
For I'm using a 2.6.x-kernel, I'm using the in-kernel drivers. OSS btw. is the Alsa OSS-Emulation, not native OSS.
Try to reproduce with alsa-driver instead, if that works, the problem is up to the kernel team.
Unless otherwise told, moving to kernel.
Please reproduce on the latest development kernel, currently 2.6.16-rc2
Please reopen when the latest development kernel has been tested.
