Description of problem:

After playing for a while, the audio simply stops working. A log record appears in /var/log/messages:

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

alsa-utils-1.0.20-3.fc11.i586
alsa-plugins-pulseaudio-1.0.20-2.fc11.i586
alsa-lib-1.0.20-1.fc11.i586

The bug started to appear after installing the new kernel:

kernel-2.6.29.6-217.2.16.fc11

How reproducible:

Just have an application (e.g. xine) play for a while.
The sound will disappear eventually (usually it takes 5-10 minutes).
