TCL HomePod Apple TV Dolby Atmos issues
I've searched this topic for about a couple months now and haven't figured out how to resolve this issue. Dolby Atmos used to work just fine on my Apple TVs connected to full size HomePods but hasn't since I guess 26. 3 maybe? No DA indicator, nothing. Sound comes out of the HomePods but I don't think it's DA. I've tried the following:
Wiped the Tv, HomePods, and Apple TVs. Changed my HDMI cable to a high speed, and fiddled with the HDMI compatibility settings. Moved the HomePods to an Apple TV that is connected to a working Sonos system that does display DA properly.
One TCL is a Roku 4K Dolby Vision TV to which the HomePods are connected to. I also tried using the HomePods with my TCL Google TV, so I don't believe the OS is the issue.
Any ideas?
