Sonos 12.0.5 Update: Delivers Dolby Atmos to Arc with AppleTV

Now when I disable eArc on my Samsung I get this showing in the S2 app. It appears that ATV 4K is sending an uncompressed True HD Dolby Atmos signal your my Sonos Arc based on a comparison of the two screen shots from my previous post. 

What I find interesting is that LG shows the latest update as version 3.10.28 from 8/11/2020. The listed changes are 

1. Improvement  
 1) Support AMD FreeSync 
 2) Sport Alert improvements  

I will have to try my tv later cause I have a similar 2020 model. 

You need to have the newest which is firmware is 03.10.60 according to khazz22 above.  That version shows up on the LG website in the US.   I have the version 3.10.28 you mention and it doesn’t work., so  hopefully they should roll it out soon for 75Nano906NA (Europe).

version 03.10.60 (US) shows

[03.10.60] 
1. Fix black screen appear issue when booting the TV 
2. Fix the issue of re-running certain application or rebooting TV 
3. Improvement of the issue where certain BT Audio devices cannot be searched

Thanks for this, what does the app say when you try to play regular 5.1 content (not Atmos) from Apple TV?
