Public bug reported:
getting weird log messages in sys.log:
alsa-sink.c: ALSA woke us up to write new data to the device, but there was
actually nothing to write!
Oct 8 17:54:40 mika-laptop pulseaudio[1572]: alsa-sink.c: Most likely this is
a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.
Oct 8 17:54:40 mika-laptop pulseaudio[1572]: alsa-sink.c: We were woken up
with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another
value < min_avail.
