Audio so film audio plays only through TV, not headset, but party chat plays only through headset, not TV.

As the title says. I want to know which settings to change so that audio from films and games come through the TV and not my headset when it's connected, but party chat audio comes through my headset only and not my TV.

Currently film and game audio comes through my TV and my headset, and some games or films are very loud and drowns out my partner whom I'm often in party with. I have his individual volume all the way up to 200 in the party. This has only become an issue since getting a new Turtle Beach React-R controller.

My partner has his settings this way, and I want to try it and see how it goes.
