I have QE65Q90R TV, HW-Q90R soundbar and Xbox One X. I have connected Xbox to my soundbar HDMI1 port and soundbar to my TVs ARC port. All firmware is up-to-date. Every time I try to watch any Dolby Atmos content soundbar shows Dolby Atmos message and immediately goes back to TV ARC. Dolby Digital+ is turned on. I have tried to reset my soudbars factory settings, my TVs factory settings, even my Xbox. After all resets Dolby Atmos worked for about an hour and then again immediately changes to TV ARC again. What can I do?
