Hello!
I have an AST Advantage 826 with a built-in sound card. It's a Crystal CS4232 with a real OPL3 on the motherboard. A ribbon cable connects the motherboard to a second daughterboard containing the wave-table capability built with QDSP QS700 and LGS GMS80C501. It's not a standard waveblaster-type board, however; it's an AST proprietary PCB containing also the output jacks for the sound card and a CD-audio connector. I am using the CS4232 drivers version 1.80 from this page: http://www.vogonsdrivers.com/getfile.php?fileid=925. I'm using the stock cs4232.ini included with that driver download.
These are the components of the sound card that are located on the motherboard:
These are the components located on the daughterboard:
All the functions of the card seem to work nicely except... under DOS, I cannot hear the wave table. I am making the assumption that the wave table is connected to the MPU-401 function of the Crystal chipset, so I configure the game for General MIDI on port 330. The test utility (say, the imuse.exe utility that comes with Tie Fighter or setup.exe in Descent) appears to play the MIDI file but there's no sound. I don't have an external MIDI device to connect to the game port to test the MIDI output there.
I have un-muted all the inputs in the CS4232 mixer:
Do you have any idea how to enable the wave table audio to the CS4232 mixer? There is a mystery jumper on the sound card I have tried on/off. I have also tried all 4 combinations of XCTL1/XCTL0 in case those are connected to some kind of external MUX that handles wavetable audio.
This seems like it should be simple. What dumb thing am I doing wrong?
