Public bug reported:
Binary package hint: pulseaudio
The symptoms of this bug are extreme jitter in the sound coming from
Wine applications. It sounds like the sound has slowed down massively
with huge gaps between each sound.
What is happening is that the Wine application is losing the sound
connection and reconnecting dozens of times a second - which causes the
jitter. You can confirm the fault by going to the Applications tab in
the Sound Preferences applet. You will see that the page flickers
between connected and 'no application running' as dozens of disconnects
and reconnects are processed.
The jitter effect is intermittent and sometimes stops. Often though you
have to restart the Wine application and/or the pulseaudio daemon to get
the effect to clear completely.
