So I have USB wired Logitech G933 Headphones, and Rocksmith doesn't seem to detect these as a viable sound output on PC, which is odd because they work just fine on my Mac. When i plug the headphones in via AUX cord, they work just fine. But I like the USB connection because the headphones are 7.1 surround sound, but if Rocksmith doesn't detect them, what should I do?
