Issues with getting SURROUND SOUND TO PLAY DOLBY ATMOS. I keeping getting PCM 2.0

I currently have a surround set up with the Sonos Arc and two SL ones and gen. 3 subwoofer. When I’m playing a movie with Dolby Atmos it is not showing in the sonos app that its  coming through as Dolby Atmos. Instead it is showing pcm 2.0.. I have my system playing through a Samsung QLED Tv model Q80 . This is driving me nuts!!! Any suggestions would ge appreciated!

Is the Pass-Through option greyed out? If you set HDMI eARC to Auto, can you select Pass-Through? If not, try playing The Tomorrow War on Prime Video, and while it is playing, check if the Pass-Through option is available.

Are you using the HDMI cable that came with the Arc?

I am able to select the Pass through option but that has not worked. I upgraded my HDMI cable.

Is it absolutely necessary to use the HDMI cable that with Sonos ARC?

To verify it works? Yes. Using another cable just adds another possible problem to the mix. Of which there are many with getting Atmos playback to work. Once it works with their cable, THEN you can try a random 3rd party cable

Yes, you must use an HDMI cable for Atmos.

Alright I tried using the HDMI cable that came with the Sonos ARC and still nothing. I tried playing The Tomorrow War movie from Amazon Prime and still showing PCM 2.0 on my sonos app. I even tried switching the sound setting to pass-through and nothing. I’m running out of ideas any more thoughts?
