Worked it out.. sort of.

Play #Xbox on the couch.
Have Xbox app running on PC, #streaming the game.
Have #OBS capture the PC stream of the game, incl audio.
Use #droidcam to stream my face to OBS/PC.
Use wireless headset to stream (bad) voice #audio from the couch to OBS/PC.

Suggestions for better voice capture?

How/where can I make an Xbox series S accept a plugged in headset as audio input?
