[Wine] Shockware + firefox sound issues

[Randall Walls]

I have firefox installed under wine (v1.5 on 20050830) and running 
fairly well. I have installed Shockwave + flash, both of which seem to 
work as good as their native counterparts (Native Windows in the case of 
shockwave) except that sound in shockwave is jumpy and seems to be 
suffering from an underrun issue. This is the output in the terminal:

fixme:dsound:DSOUND_MixOne problem with underrun detection (mixlen=14780 
< primary_done=26856)

There appears to be one of these messages for every sound played.

Has anyone had a similar experience with shockwave under wine? Any 
suggestions? I've already tried googling this, but any search with the 
words 'shockwave linux' return 50 thousand posts from people asking if 
shockwave works on linux. Shockwave wine returns some info, but nothing 
recent and nothing mentioning sound issues.

Thanks
