So I got a new Sonos Arc and connected it all up. I watch my 4k blu rays on the Xbox.
I see in the Xbox menu I can choose either dolby digitial or dolby atmos.
My TV only has HDMI(ARC) not the E-ARC, so it cannot pass dolby atmos, but it can pass dolby digital plus, which is what I need to get the scaled down atmos.
In the Xbox if I select dolby atmos it rightly tells no can do, because my TV can't pass it. If I select dolby digital it outputs 5.1 even when an atmos track is playing.
So..... can the xbox one output dolby digital plus (lossy atmos) or do I need a dedicated 4k player for that?
