I am unable to get Dolby Atmos playing via by Beam 2 and LG OLED B4. 
 

I have tried with “The tomorrow war” and other movies suggested to ensure Atmos is available but I just have “Dolby Digital Plus 5.1” on my Sonos app.

 

beam 2 HDMI is connected to eARC. 
“Sound out” = HMDI(ARC) device 

“DTV audio setting” = Dolby digital plus (I have also tried auto)

”digital sound output” = pass through

”eARC support” is toggled to on

 

”select HDMI input audio” is greyed out

If anyone has any suggestions please do share!

 

Moderator edit: Changed Beam to Beam 2 for clarity

Amazon Prime requires the Ad-Free subscription for Atmos and 4K.  If you have Disney+, they have the most Atmos titles and it is included with all subscriptions.

​@Jav_8 

You are talking about „Sonos Beam“ (what is also shown on your profile) and not about „Sonos Beam2“. What generation of Beam do you use… gen1 or gen2? 
Only gen2 supports dolby atmos.
