I unscrewed the Rift headphones and went to the settings to switch audio output and input to Windows Default. Whenever the USB 3.0 cable is plugged in, there is no audio in the headphones I'm using. Unplugging it works, but then I obviously can't use the Rift. This didn't suddenly happen when I unscrewed the headphones, but now that I'm trying to use the non-Rift headphones with the Rift, it's a problem.
