Public bug reported:
Binary package hint: pulseaudio
I've recently upgraded from Lucid to Maverick and the sound system does
not work properly anymore. After a few minutes playing sounds, the sound
output will stutter then stop, and the system will become sluggish. If
I'm fast enough in killing pulseaudio (pulseaudio -k), I recover a
working system and sound too. Otherwise, the system will hang hard; not
even SysRq magic is working.
The hardware is a motherboard chipset: 00:1b.0 Audio device: Intel
Corporation 82801JI (ICH10 Family) HD Audio Controller.
The working system was kernel 2.6.32-25 and pulseaudio
1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14.
The nonworking system is kernel 2.6.35-22 and pulseaudio
1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu21.
Unfortunately, the logs do not contain anything relevant at the time the
system breaks down. In case it helps, there is the following message at
system start though (which I didn't have in Lucid):
Oct 12 10:08:41 saline pulseaudio[1726]: alsa-util.c: snd_pcm_avail_delay()
returned strange values: delay 0 is less than avail 16.
Oct 12 10:08:41 saline pulseaudio[1726]: alsa-util.c: Most likely this is a bug
in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.
