I have a 2020 Samsung qled with arc and I can only get Dolby 5.1 over arc and the Sonos website says I should be able to at least get compressed Atmos over arc. I’ve tried it all I feel and I’m stumped

Ok, I found out the reason…

There‘s another feature LG tvs support. They are able to convert Dolby MAT to Dolby DD+.
So for a regular tv with enabled Atmos and just ARC you will need a device like FireTV that outputs DD+, but for an AppleTV that outputs MAT you need one that on top is abble to convert MAT to DD+.

What a simple world… 😂

My guess would be there would be an extra license fee for passing through atmos but I am guessing

l know that LG stopped Dts pass through for a few years after my model tv and Samsung doesn’t support Dolby vision one reason I never buy that brand tv but as I said it’s purely guess work on my part 😊

I’ve just been using the tv to stream atmos content and my Apple tv for regular 5.1
