This is the Opti MAD 16 Pro. Try this driver, it should work then.

When still having resource conflicts in Windows I suggest going into the BIOS and turn of PnP OS and let the BIOS assign resources automatically. Reserve IRQ5 and 7 to legacy ISA . Try another ISA-Slot as well.

I have a 82C928 and a least for me unisound driver works better then the official driver which wouldn't allow music AND sound in Doom. You could only have one or the other.
It's a dos only machine so can't help with WIn9x

According to this the 82C929A is slightly different but also pretty bad in windows. Maybe give up trying to get the Opti working in windows and focus on dos?

I've tried to install in DOS but when I run the setup it says soundcard not installed 😖

Are you certain that the main chip on the card is an Opti 82C929A ?

Could you please post some photos of the card with chip markings visible ?

Thank you.
So the software used matches the card. If that is the actual card you have (not just the same model), there are light signs of corrosion visible on the photo and the driver floppy looks like it might have been exposed to humidity. In that case, it might be worth inspecting the card for visually detectable damage or corrosion and cleaning the ISA connector with contact cleaner to make sure that is not the issue .

Yeah the floppy was shot, Ill give the card a good cleaning. Thanks for all the help above.
