Does anyone know why my tritton ax720 headset isn't working on the xbox one? I have the amp plugged in via optical to the xbox one. When I have the inline adapter set to 720 AMP I can't hear any sound whatsoever, but when I change it to PC I hear sound. My xbox one is plugged in via HDMI to my monitor and my monitor doesn't have an optical out so I can't try that straight to the amp. Any help would be appreciated!
