Any compatibility issues, like reversed stereo, glitches, etc? On my ALS100, none yet. No hanging notes (with an external SC-55ST), no single cycle DMA bugs, works in DN3D with both high and low DMA and every other game I have thrown at it. In some games you have to adjust the volume of the music …

Looks like you have an ALS007 or ALS100 based card, same as the one discussed on page 5/6 of this thread. These cards are probably some of the best dos sound cards out there in terms of compatibility - just add a wavetable card or external synth

Those terratec cards use the Via Envy24 chipset.. good windows cards but no dos support whatsoever
