I have a Sound blaster Audigy 2, in my new soyo and it all of a sudden doesn't work. It worked just fine in my P4B533 Asus, What would be some possible problems. ~temporal~
I know Creative can be picky about the IRQ's, so that could be a problem. Try putting it in a different PCI slot, and preferrably not the first one, as they typically share the same IRQ as the AGP slot.
