You're right, that's what you have to do right now.
I'll look into this.

What you're hearing is skipping because Squeak isn't able
to fill the sound output buffer in time. On Win95, setting
the sampling rate to 11250 in SoundPlayer>initialize yields
smooth sound output, at least on a P133. Another possible
problem may be that your CPU is not fast enough to support
4 voices. What kind of CPU do you have, and what's its clock
speed? Does it have an L2 cache?
The sound interface code in the Win32 Squeak VM ignores
the BufferMsecs setting, so it won't help to experiment
