I'm looking for a new headset for gaming and music, and I'm wondering if I'd be able to use a USB headset the same way as my current 3.5mm setup. I basically have my 5.1 speakers plugged into the back of the comp, and the 3.5 headset into the i/o jacks on the front of the case. That way I can have soudn in both my speakers and my headset, and I can just power down the speakers if I want to use the headset. Would I be able to do that if I get a USB headset?
