Well, because you said your OSS driver
treats mono as stereo, I expected this
patch won't help you. But as it definitely
fixes the distortion for me (tested with
Goblins 1 and 2), I have commited it to
HEAD regardless.

IIRC Stunts uses an FM sound in SB mode,
which is not implemented yet.
You can set Stunts to MT-32 mode, which
is implemented and is supported by midid.

Prevent and do what? Not opening at all?
You can just set $_sound=(off) for that.
To do that properly, dosemu or some
external software must convert the mono
sound stream to stereo, and preferrably
also resample it to 44100. Then your
problem as well as some other problems
will disappear.

For people with buggy drivers I wrote an
excellent test-case sound driver which can
be found here:
http://www.geocities.com/stssppnn/pcsp.html
It is intended to be 100% correct :)
Try it with dosemu and see if the patch
fixes the problem with that driver.
If yes - your driver is buggy and the ALSA
must be attempted instead. Btw, if you
know your OSS driver is buggy, why don't
you use ALSA? Is there a support for your
chip?
But if the sound is still distorted even with
the patched dosemu and that sound driver,
then we have to dig for another bug in dosemu.
