That card is not sb16 compatible, try with wss or sb pro (or covox/disney sound source)

Run the diagnistics program and check the sound there. Verify mixer levels.

In the mixer utility, there is also an option to choose between mono or stereo mixing. Choose mono (it will still produce stereo output).

I have noticed that the card seems to have a lower volume at the default settings. Just increase the digital sound output but, just be aware that some games might reset it again back to default.

Thank you for the suggestions, I will definitely check out the mixer program later.

Tried using the mixer TSR. Most games seem to default it to mono. I set to stereo and save, just to try something different. That did not seem to help. What is odd is in Wolf3D if I set it to disney sound source then it works. Sound is perfect. Seems like whenever I set it as SB / SB16 / SB Pro no games I've tried like to play digital sounds. Very odd. I tried panning hard left and hard right for balance, that did not seem to change anything.

Verify your Set Blaster environment variable and that it matches the configuration of the card.

Run the Diagnose program in the Utility directory again to test your settings. Stick to the default of A220 I5 D1 T4. You can also try IRQ 7 but make sure you don't have any resource conflicts (like your parallel port).

Most likely, you are using a multi I/O card with jumpers on it. If you can figure out the jumper settings, disable LPT1 & COM2 (unless your are using it).

Thank you for the additional advice. The reason I was trying to use this card, other than the fact that I like to try and use all different cards in my old PCs, is that I needed a non-PNP card. This is for a 386 build, and it's BIOS does not have PNP support. I tried this card on various IRQs and other settings. Environment variables were good. I tried to change the "T" type in the blaster settings to different variants, but literally nothing helped. I don't know if this card is bad or what. I will definitely try it out in a different computer at some point. I had another Aztech card, this one was a Packard Bell sound / modem combo job. This PC did not like that sound card either. Similar issues. FM music played fine, but no blaster audio. Finally I checked one of my other computers and found I had an Opti card with a PNP disable jumper. I installed that card in this computer and now it works great. I've tried multiple games and it works a treat. Come to think of it when I installed the card in the 386 I forgot to jump the "disable" PNP jumpers; yet doesn't seem to cause any issues. Not sure if this computer just hates Aztech cards or what. I will def have to test them in another machine one day.
