Hey all, this should be a fairly simple one to figure out. I've got on board sound and a sound blaster card. Knoppix sees them both because when I go in to mixer it sees them both. But I can't figure out how to get the sound to go through the blaster card and not the on board sound. It works fine on the on board sound, but I want it on the blaster. I've tried opening up Device Manager but it opens for a second and then closes on its own.

So how do I tell Knoppix which card I want to use as the default card?
