I have been trying to get 4K and HDR working and have Dolby Atmos.
So far if I connect from the Xbox to HDMI 1 on the Soundbar and HDMI Arc out to the TV HDMI 3(Arc) I lose HDR from most Xbox apps.
Please help.
I have replaced 18Gb HDMI cables with monoprice HDMI 8k cables with no change.
If I connect to the TV first and then HDMI Arc out the soundbar I lose Dolby Atmos.
