I managed to get sound output working so I can hear and get surround, but my microphone doesn't appear to be working. In party mode on the xbox it says it can't detect a Microphone for me. 

I found this, and I have done steps 1-3 no issue.

What I don't get, is steps 4 onward.

Is it saying in order to get this working I have to install an app on my phone and then run a cable from my mobile to my gamedac? that would seem to defeat wireless?
