I just bought the E-MU 0202 DAC, and I'm trying to be able to adjust the volume of the inputs (MIC and Line-In) via windows for use of my XM radio and microphone. I can adjust it from the device itself, but I can't find a way to adjust it in windows. If I can't, it's pointless to use the inputs because I store the DAC in the back of my car.

If anyone knows how to adjust the volume via windows it would help me out alot.
