Apple TV 4k

So I have the newest sony oled tv a90j hooked up to my sonos arc surround sound via earc hdmi 2.1. When I play any streaming app Hulu,Netflix,ESPN,YouTube and Disney plus from the google tv that comes with the tv already I get Dolby digital 2.0 or Dolby digital plus 5.0 or Dolby atmos which is great. Now I bought the newest Apple TV 4K and when I play any other app other than Netflix (I get Dolby vision 5.0 if set to Dolby vision or Dolby atmos if set to atmos only on Netflix)all I get is stereo pcm no matter what setting I put on the Apple TV in. Tried Dolby atmos setting on Apple TV or Dolby digital setting on Apple TV and nothing all I get is stereo pcm no matter what app I play Even Apple Music on the Apple TV all I get is stereo pcm. Any ideas as to why or how I can fix it? Or is Apple newest 4K Apple TV can’t pass any Dolby content unless the app actually has it like Netflix for example.

If you can see Video and Audio﹥Audio Format﹥Immersive Audio, then Dolby Atmos is available for sources that have Dolby Atmos. That option would be hidden if the capability wasn’t detected.

Apple TV outputs Dolby Atmos in Dolby MAT format, which is like PCM, not like DD+. Any indicator on your equipment may show “PCM”. That doesn’t mean Stereo. It means PCM Multichannel, optionally with Atmos extensions (when available).

Not all content offers Atmos. Check for the Atmos symbol on the Details page for a title.
