I managed how to configure SC-88VL with my PC and it required reinstall OS, with win98SE in DOS mode didn't want to work. DOOM and DOOM2, both work amazing with Sound Canvas but with Duke Nukem 3D I have a problem. When I set it up on AWE32 everything work well but when I'll set up music card on SC it starts to stutter with random animation drops together with music 'pauses' and with random moments game hangs at all.

Ok, changing FX from 44kHz to 16kHz resolved the problem.
