I have the Turtle Beach X41 headset from my 360 days. They run off the optical out port. I have been concerned because they will be sending game audio to the headset as well as the new controller/adapter sending audio.
I got the adapter today and updated the controller. The TBs are running off of the optical out port, which is set to Bitstream, and the Bitstream is set to DD 5.1. The audio is excellent when not using the adapter. As expected, both audios are present once the adapter is plugged into the controller and I plug the headset into the adapter. If I turn down the TB audio, then I am just hearing the stereo audio coming through the controller / adapter (kind of defeats the purpose). If I turn the mix to 100% chat and 0% game audio on the adapter, and then turn up the TB audio on the headset, my friends get an echo from their chat. Anybody else having this type of issue with 3rd party headset?
