Public bug reported:

Running an Alienware system on (I believe) the internal audio.  Chasing
after a repeated interface crash (pointer visible and moving, but no
response to input), I turned up the following in syslog:

Aug 20 06:47:53 goblin pulseaudio[15844]: alsa-sink.c: ALSA woke us up to write 
new data to the device, but there was actually nothing to write!
Aug 20 06:47:53 goblin pulseaudio[15844]: alsa-sink.c: Most likely this is a 
bug in the ALSA driver 'snd_emu10k1'. Please report this issue to the ALSA 
developers.
Aug 20 06:47:53 goblin pulseaudio[15844]: alsa-sink.c: We were woken up with 
POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value 
< min_avail.

** Affects: alsa-driver (Ubuntu)
     Importance: Undecided
