Description David Baron 2008-02-03 02:07:38 EST
Description of problem:  After running for a few days, sound pretty reliably
stops working.  I'm not sure if it's the number of suspends+resumes or something
else.  (Although I'm pretty sure it has worked after a single suspend+resume.)

Version-Release number of selected component (if applicable):

How reproducible:  Pretty much always, although it takes a few days.

Steps to Reproduce:
1. aplay /usr/share/sounds/warning.wav (after running for a few days)
Actual results:
aplay hangs after printing:

Playing WAVE '/usr/share/sounds/warning.wav' : Signed 16 bit Little Endian, Rate
44100 Hz, Mono

When I hit Ctrl-C, it prints:

Aborted by signal Interrupt...
aplay: pulsecore/mutex-posix.c:85: pa_mutex_free: Assertion
`pthread_mutex_destroy(&m->mutex) == 0' failed.
Aborted by signal Aborted...

The following pair of lines is added to ~/.xsession-errors :

ALSA lib conf.c:3949:(snd_config_expand) Unknown parameters 0
ALSA lib pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM front:0

Expected results: sound plays

Additional info:  Sound seems to fail in all applications except for the
terminal bell in gnome-terminal.

And the following gets added to /var/log/messages:

Feb  3 06:57:57 ridley pulseaudio[2743]: module-alsa-sink.c: Error opening PCM
device front:0: Invalid argument

If you do suspend - resume you are subject to a hal problem.
