I am going to be getting a receiver for decoding 5.1 and 7.1 streams (mostly gaming type stuff) and i'll be using an external DAC for my stereo listening needs. The problem I'm having right now is that my DAC (amb gamma 2 F++) is getting a horrendously noisy signal from my computer's USB ports ever since I added a solid state drive, and I have no idea how to fix it. Everything is attached to the same power strip, and I dont think it is a ground loop issue. Anyways, right now i cant do more than 2 channel output to DAC so a sound card is definitely the solution. The computer has no other way to do digital output.
What would you guys recommend?
