One of my beloved 2MB Ensoniq SoundScape S-2000 ISA sound cards suddenly stopped producing any & all audio output whatsoever, although the card is detected fine in both DOS and Win98. Everything on the actual card looks solid, but I'm far from an expert on this kinda thing. Anyone have any advice on what I can check/test? I've tested in multiple machines, and I've already swapped with an identical card that works fine.
