Hi guys, basically, on the xbox one original headset and my new turtle beach set, I had the same issue. I can hear all sounds through the speakers, but I can hear no voice. my NAT is open and preferences are all open for voice. I did a test, I recorded my voice in a message, it recorded one just fine, but I couldn't hear it through playback. When I unplug my microphone I can hear voices through the TV. Wtf? I don't have a Kinect either..
Thanks for the support
