I'm not sure why this is so difficult
Xbox is Windows 8 based
Almost all PC (Windows) headsets use USB as the primary chat in/out while using optic for audio
Why is Microsoft so incapable?
Instead of trying to constantly update that craptastic "stereo adapter" that ruins all audio/chat experience, do it the right way and make USB chat possible
Oh, and fix the volume issue when in a party; that is getting INCREDIBLY annoying.
Piece of advise: Nobody, EVER, in the history of ANYTHING could have possibly thought that having the audio run out of the controller could POSSIBLY be a good idea. Are your engineers just plain fool?
