I have a Sound Blaster Z sound card and I use it with my Sennheiser PC360 headset, but the microphone on my PC360 stopped working so I'm sending it to Sennheiser for repair. While it's gone for repairs, I want to use my old Logitech G930 USB headset but no sound will come through the speakers. I know the headset works and I'm assuming I can't hear anything because the sound card is processing it while there's nothing plugged into it.

tl;dr - How do I temporarily use my USB headset while I have a sound card installed? I have my headset's microphone and speakers set as default device right now but only the microphone works.
