I have a Sonos Arc + Sub connected to my Samsung S95B eArc HDMI port and connected to the same TV, to another HDMI portM, an Apple TV 4K (3rd Gen). The TV is setup for passthrough and when I increase or decrease the volume it shows Sonos Arc (eArc HDMI). Apple TV shows, in the settings, under immersive audio, Dolby Atmos. From my understanding it everything is properly setup.
When I play content, be it Apple TV+, Netflix, HBO Max, etc.. and press down button on the remote to look at the Info Window it shows it’s playing 4K Dolby Vision but no Dolby Atmos label. As a matter of fact Dolby Atmos label only appears on Apple TV+, very rarely, and then disappears. When browsing for content the apps they do show support for Dolby Atmos.
What confuses me is that while playing the content (Apple TV+, Netflix, etc..) the Sonos App shows the Dolby Atmos in both “Now Playing” and System Information.
The question I have is: which one is correct? Is Apple not aware it’s playing Dolby Atmos content or is the Sonos app for some reason incorrectly labelling the content it’s receiving as Dolby Atmos. It’s my first Dolby Atmos setup so I don’t even have a reference to compare with and understand if it’s Dolby Atmos or not.
