A:
The CineMate GS Series II system would connect to the audio output of your TV and the system offers both digital optical and analog RCA audio inputs. So long as the TV is receiving audio from your Xbox One, it should pass that out to the CineMate GS Series II system. Additionally, to be sure you are receiving full surround sound signal from your connected cable or satellite box, we recommend that you sign up for the Microsoft surround sound beta from the Xbox home screen.
If you have any difficulty receiving audio from the Xbox, we’d encourage you to follow up with Microsoft’s support. We’ve included two Xbox support articles that deal with the concerns you have raised.
Thank you.
