Atmos Not Working On My Arc

I just recently got my Sonos Arc to complete my setup. My current Setup is a wall mounted Sony A9G ,Sonos 1 (2x), Gen 3 Sub and Sonos Arc.I tried to google what streaming services support Arc so i can see what this Sonos Arc can really do. I found some movies on (Netflix, Disney Plus) but I don’t see “Dolby Atmos” on my app. So maybe i’m doing something wrong? Any help or insight would be greatly appreciated.  From some vids I found in YT I “should” be seeing “dobly atmos’ in my app.

    I’ve found this helpful thread about the same concern and it seems that this is a known issue with Disney+.

    On a quick Google it seems that your TV supports Atmos on the TV's internal speakers.  It isn't clear that it will pass through Atmos to an external speaker. I'm not sure what the position is but I think you should clarify what you can really expect.

    jnew402,

    It not quite clear from your post, but to view/hear movies with Atmos audio on Netflix you will need to subscribe to their premium plan. I mention that just in case you are subscribed to one of their basic plans.

      Youtube does not support anything other than Stereo sound. So, you will not be seeing Atmos from Youtube. 

      As for Netflix: as @Ken_Griffiths stated, you must subscribe to their premium (most expensive) plan to get Atmos content.

        Yea my tv has an erac and I have it plugged in correctly. I upgraded my Netflix to the 4K subscription today. Something strange happened I looked in my app it said Atmos for like 5 seconds and went away and the sound cut off. I switched the audio to PCM and sound works but no Atmos. The movie I had on Netflix supports Atmos. Idk

          Yea I understand YT doesn’t support Atmos; I was looking for some help on fixing it from a YouTubers  video

              I’m not understanding! It worked 1x for a few seconds and then stopped. I will try to unplug my arc maybe? idk what’s going on

              Ok I THINK I figured it out from this video.

              Anything being streamed (Netflix UHD, Prime Video, Apple TV etc)  will be need “compressed”.

              And anything coming for a physical source (UHD Dvd player) will be “Uncompressed” 

               

              So since i’m using streaming services in UHD the sound output on my TV and my Sonos App needs to be “compressed”. So I went to my TV options and selected compressed audio. Then in my Sonos App: Go to the Gear in bottom right: Select System; Select Audio Compression: Select Compressed”

               

              Once I did this my Atmos option worked fine. So I assume once I watch movies on my 4k dvd player i’ll need to change to “Uncompressed”

                The audio compression setting in the Sonos app relates only to analog line in. It has no relevance here.
