Comment (by btb):

 I think I see a similar issue, but on different versions/hardware.
 On Fedora 10 on a AMD 64 x2 with pulseaudio-0.9.13-6.fc10.x86_64 I have
 choppy/jerky
 output on the plugged in board:
 {{{
 01:09.0 Multimedia audio controller: Fortemedia, Inc Xwave QS3000A [FM801]
 (rev b2)
 }}}
 (which used to work great a while ago before moving to Fedora)
 but not when I use the on-board audio:
 {{{
 00:05.0 Audio device: nVidia Corporation MCP61 High Definition Audio (rev
 a2)
 }}}

 /var/log/messages shows messages like:
 {{{
 Jan 25 19:53:51 rigel pulseaudio[17774]: module-alsa-sink.c: ALSA woke us
 up to write new data to the device, but there was actually nothing to
 write! Most likely this is an ALSA driver bug. Please report this issue to
 the PulseAudio developers.
 Jan 25 19:53:55 rigel pulseaudio[17774]: module-alsa-sink.c: Increasing
 wakeup watermark to 354.01 ms
 }}}

 I'm very very new to pulseaudio so I have no clue yet what kind of
 information you'd like to
 see that would help to track this. In fact it took me half a day to figure
 out how to get
 mplayer to send stuff to this fm801 board, which I find rather long with
 15 years of
 linux experience.
