unfortunately I still don’t quite understand the topic with the settings for 3D sound (Dolby Atmos, Auro3D, DTS-X) on the AppleTV 4k.
In the ATV I activated Dolby Atmos as a sound option (immersive).
My source files (movies) have a TrueHD 7.1 Atmos track.
When I play these, my Denon X4700 AVR shows me PCM as usual. I can also see that the height channels are also being operated.
I can also turn on Auro3D.
Do I now have lossless 3D sound or do I have to change something?
I am using Infuse with Plex Media Server.
