Hey All.
I'm using an almost Identical card, but am having trouble getting the wavetable expansion to work in DOS. I found one bit of info about some games just not supporting it with out a driver called "Wavetable Driver for DOS based Games (ES1688 only)" here on Vogons ESS AudioDrive (ES1868) - a surprisingly good ISA sound card. But this is for the ES1688 not the ES1868(F).
Interestingly the 1997 VxD driver for windows works perfectly and the wavetable works in the MS-DOS Prompt. The Wavetable in Windows Media Devices appears as MPU-401. In dos I'm using a driver Phil posted a while back for a generic ES1868 card, the FM works fantastic and the OLP3 works for midi but nothing I do will let the wavetable work in General Midi (or Waveblaster/Sound Canvas/other modes). Any advice would be great, W.
EDIT: After further research I'm getting the impression that Wavetable boards we're designed to be used in a windows environment. My question now is do ISA Sound Blaster 16's have native hardware dos support for wavetable boards using the header?
EDIT2: Volume mixer! ESSVOL AuxB was set to zero, thanks to badmojo for solution.
