USB Sound Blaster Odgidy 2 support

[Darragh]

Hello,
I have a really nice USB SB Odgidy 2 here which handles Software synths absolutely atrociously but is great when playing Audio.  Can any one tell me how to set this card up but not have it as the default?

I have another one which is a c-media wave card which is great with festivle, Viavoice and every other synth that I've used.  

The sb odgidy is connected to a set of five point one speakers, is it possible to have this feature enabled?

Thanks

Darragh
