Bug Description
from /var/log/syslog:
Jul 11 08:01:00 greg-desktop pulseaudio[3698]: alsa-sink.c: Unable to set switch: Operation not permitted
Jul 11 08:01:00 greg-desktop pulseaudio[3698]: bluetooth-util.c: Error from ListAdapters reply: org.freedesktop
Jul 11 08:01:51 greg-desktop pulseaudio[3698]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write!
Jul 11 08:01:51 greg-desktop pulseaudio[3698]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers.
Jul 11 08:01:51 greg-desktop pulseaudio[3698]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

Same problem here, on a Dell Latitude D830. It seems to have appeared after I've applied latest kernel 2.5.31-2 update.
Bug 397890 looks like a duplicate and mentions a work-around to re enable sound pending resolution of this problem.
