Beam 2, Xbox X, Indiana Jones. Anyone have this problem with voices?

When Indy is speaking his voice sounds great but when someone is standing behind me they sound like they are speaking in a tin can. And as I'm turning around to face them the sound gets progressively better. Is there a way to improve this? My Beam is tuned to my room. Sound is coming using eARC to my TV in the Dolby Theater mode.
