Sound issues galore

I was doing ADR on a project, then had to stop and cut a short film for a friend, now I tried to replug everything back up to my G5 and Swisstronic mixer and now I can't get sound AT ALL, making me resent doing a favor for that friend int he first place. ;> Anyone know of a website that had a diagram for the proper setting on a G5 dual processor in compatibility with a swisstronic mixing deck? Thanks.
