I have my CS4232 cards working well in MPXplay. The commands are:
SET BLASTER=A220 I7 D1 T4
SET ULTRA16=530,1,7,0
MPXplay.exe -scs wss -scv 100
Notes:
- Tested to work with MPXplay v1.58 and v1.60.
- It is not easy to get this card to IRQ 7 without EEPROM adjustment, but IRQ 5 should be fine too.
- The "-scv 100" parameter is to open the master volume of the WSS device, which is normally muted when idle in DOS. MPXplay does not mute the card at closing though. I have a custom version of MPXplay 1.60 that opens and mutes the WSS volume without this command.
- Sinds there is a GUS in the system too, I use the parameter "-scs wss" to select the CS4232 instead.
Troubleshooting:
- If the soundcard was used in Sound Blaster mode, it may not want to go back to WSS mode: Run CS32WSS.exe or reboot to fix this.
- Some games do Sound Blaster DMA Transfers without full DMA-Acknowledge at exit. After closing such a game and running MPXplay or something: the CS4232 will sound garbled. I have a small tool to fix this, borrowed from the Quake 1 sound driver. Or just run Quake 1...
