I finally received the screws for the VGA port on my GF2, so I thought I'd give it a shot. I forgot to check for bad caps, and POP! A capacitor exploded! Will have to recap and then try again.
I also tried to run both the Audigy and the YMF744 cards at the same time, thinking I would get best of both worlds: authentic OPL3, working audio, plus two joystick ports. I changed the address and IRQ, disabled DMA and MPU on the Yamaha. I could get FM output on both cards, which I solved by setting synth vol to zero on the Audigy. But I'm still facing a lot of issues:
No matter which way I try - line out of Yamaha into line in of Audigy, or vice versa, I cannot for the life of me get sound from one card in the output of the other.
Also most games besides Doom simply crash with both cards in even though I've changed or disabled everything in the Yamaha.
Any suggestions of what else I can try? Anyone having experience running 2 sound cards at the same time in DOS?
