The soundcard is part of your problem. Soundblasters are very tough to make into decent recording devices. There was a seperate driver that someone else came out with for it, but for some people it works, and others it freezes their systems or worse.
I don't have any great advice for you except if your serious about getting into recording you might want to consider a soundcard that was built for it.
Maybe someone with the Audigy Platinum can tell you what driver they are using.
