[Five]

with this series of cards you need to use the 'patchmix dsp' mixer, available in the tray (lower right) or launch from the desktop. I think you have to insert a send or something in it post back and I'll try to help out when I'm a computer that has that card. pain in the ass, but once you get it set up its a very nice soundcard.

edit: also check the pdf manual, it tells you what to do somewhere in there!
