I just got an new audio advantage srm usb sound card and tried to hook it up but all I get is a very loud buzz form all the speakers. Currently all I have for my set up is:

4ch amp, 2 channels to the front and back speakers and 2 channels bridged for the sub.

This works fine when I plug my amp into the headphone jack on my laptop but when I connect the soundcard and try it through there all I get is that really loud buzzing noise. I'm pluging the amp into the headphone input on the sound card. Hopfully by next month I'll be ordering my new system and I would like to have everything worked out before I install my new speakers and subs.
