I just upgraded my Samsung Q80R to a Samsung Q90T, mainly to enjoy better compatibility with my Sonos:Arc. However, I am unable to get Atmos audio. The Arc is connected to the eArc port, audio is set up to pass through. Using the Netflix app on the TV, I get MultiChannel PCM 2.0, while using the native Apple TV app, I get MultiChannel PCM 5.1, and while using the Apple TV 4K box, I get Stereo 2.0. Any ideas on what I need to do would be highly appreciated.
thanks
