Distorted sound with DOS 3.3 Launcher

[spector@vax2.concordia.ca (Mitchell Spector)]

	A few weeks ago I installed John MacLean's DOS 3.3 Launcher 
(version 2.1) on to my hardrive and proceeded to convert various 5.25
diskettes to use with it. While I've noticed a few glitches with 
certain modified versions of DOS (it dislikes Diversi-DOS) and other
kinds of unusual disks in my collection, there's one thing that baffles 
me. It's distorting sound-effects and music in various games! Speaker 
toggling sounds like it's a few octaves lower and somewhat rough, 
certainly different from the way it _should_ sound (yes, it's at 1 MHz).

	I'm using it on an IIgs, launching the images by double-clicking
the DOS3.3 image-icons from the System 6.0.1 Finder. Is this a side effect
of GS/OS, where sound should be distorted? I have noticed whenever I launch
ProTERM 3.1 from GS/OS, the sound on that too is distorted in almost the
same way (beeps to signal a transfer is done, or siren when rotary dialing).
ProTERM of course runs under ProDOS 8, and so has nothing to do with DOS 3.3
Launcher, however it is an 8-bit program being launched from GS/OS. Has anyone
else experienced this? I'm curious whether or not this sound distortion is 
normal, and if not, what is causing it.
