Reece:
I purged pulseaudio and checked that it had not been re-installed. I run Ubuntu 9.04 with all updates. I also use a test version of alsa-driver since my sound card is difficult to recognize but so far have had only great results -- no impact on wine at all. 
The problem I am experiencing manifests itself in the program freezing... could be the sound, could also be the buttons doing something odd. One button's on-off toggle switches suddenly with no input on my part. 
Regression test is below.
