Hi there anyone that can help , I've got an issue with prince of perisa 1.3 , when I pick sound blaster as my audio choice either for music or sound the character stays crouched and won't move.

This doesn't happen with my mt32.

The games still running because it displays the time but controls won't work , is this possibly some kind of conflict issue?

I'm using the sound blaster pro 2 ct1600 of its any help and I don't have any joysticks connected to eliminate some variables.

Okay upon further testing it seems okay with sound blaster for the music just not the sound effects , that causes it to lock up.

I've seen this behavior with Prince of Persia many times and it usually happens when there's an IRQ conflict.
Try to set a different IRQ on the CT1600 card and see if that works.
DMA 3 might also be an issue, yes. Why not use DMA 1?

2 x PLCC-68 / 4 x PGA132 / 5 x Skt 3 / 1 x Skt 4 / 9 x Skt 7 / 12 x SS7 / 1 x Skt 8 / 14 x Slot 1 / 6 x Slot A
5 x Skt 370 / 8 x Skt A / 2 x Skt 478 / 2 x Skt 754 / 3 x Skt 939 / 7 x LGA775 / 1 x LGA1155

Right then it probably is an irq issue , drat.

So for the dma thing I've also got a gravis ultrasound in the same pc , and I think at the time I was mucking about with different address and dma settings to get certain games to work and the two cards to play nicely together.

For some reason I settled on dma 3 , maybe because I was worried the gravis might hog dma 1 automatically. But I guess I probably might need to change it back then.
