if I setup everything so that Xbox connects to the TV and then TV to the Soundbar ARC channel I get a very noticeably audio delay when using Dolby. Otherwise everything work fine, HDR10, freesync etc.
so tried connecting the Xbox to the Soundbar instead, audio lag is a lot better if not perfect and had the added bonus of Atmos then working. HOWEVER HDR10 and freesync no longer work. The freesync I can understand but the Q80 Soundbar is advertised as being able to pass on HDR10.
is there some setting or something else that I'm missing?
