For posterity, since I didn't find this answer anywhere when I looked for it.
Problem experienced with GUS Classic v2.4: In Duke Nukem 3D, the music sounds fine but sound effects are full of crackle.
Solution: Reduce mixing rate to 22 Khz in setup, and like magic the problem goes away.

I remember this problem happening to me on my dad's old Toshiba but that was running a soundblaster 16... I never did figure out why it happened.
Most of Duke3D's sounds are in 8000 hz sampling rates, only a few are ever ~22050 hz. You're not missing much by having the sound set to 22 Khz or even just 11025.
By the way I'm curious, why do the sound effects have some "surround sound" effect going on, is that what the GUS driver does?

No doubt. I have the most trouble with the voice-overs getting muddled or lost in the noise. I wish they had a separate volume control.

I haven't looked at that yet. I thought it was stereo desyncing due to data loss on a multiplexed channel (some old Sound Blasters did this too), but it could be a feature as you suggested....
Edit: At 22 kHz, the stereo steering for sound effects seems to be favoring the left channel for some reason (again, the music is unaffected), but I'm not noticing a big "surround" effect. There's still some crackle, but it's mostly below the noise. At various times at the 44 kHz mixer rate the desyncing was bad enough to justify a restart.
