I have been subscribed to the pulseaudio mailing list since I started
investigating this issue in Wine. Of interest is
https://tango.0pointer.de/pipermail/pulseaudio-discuss/2009-February/003150.html.

Essentially, for the Linux distributions that do not have sound glitches (e.g.
Fedora), they have very low scheduling latencies (around 5ms) whereas the ones
that have glitches (e.g. Ubuntu) show a latency of around 210ms. It is this
high latency that causes the ALSA audio buffer to run out before data is
fetched again, and thus cause sound glitches.

This is no longer a Wine issue. It is an issue with pulseaudio and the Linux
kernel configuration. If anybody is experiencing any further pulseaudio issues
they should file a bug report with their distribution and point them to the
link above.
