Hello,
sometimes it occure that my speakers do not play sound although the speakers should play music with VLC. Then i took a look at /var/log/messages and found this:
Jan 13 17:01:39 riker pulseaudio[3335]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Jan 13 17:01:39 riker pulseaudio[3335]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. Jan 13 17:01:39 riker pulseaudio[3335]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.
The output of utils_alsa-info.sh is there: http://www.alsa-project.org/db/?f=1767e9bc745724a67c908549d20c137375d0605e
I didn't know wether this is a bug or a misconfiguration of my openSUSE 11.2
