What exactly are you testing with Dolby Atmos? What apps and devices are you using? 

I test to watch a movie on Disney +

The movie has Dolby Atmos support. 

When im lock in my sonos about system in The setting im only get dolby digital plus 2.0

Are you using the native Disney+ app on your TV or from an external media device?

From The tv. 

When you play The Mandalorian, what audio do you get?

Dolby digital + 5.1

From what I’ve read on Samsung forums, it looks like Disney+ doesn’t currently support Dolby Atmos on Samsung TVs. Have you tried Netflix? If you try Netflix, make sure you have a premium subscription.

Okey?

Thats strange, i have seen alot of vidios When it works but i have a feeling that i need to have hdmi e-arc. My tv only has hdmi arc. 

Netflix in sweden dosent support Atmos. 

Wrong by Mee. 

But i dont get The dolby atmos to pop up on Netflix. 

eARC is more important when streaming from external devices. Once Disney+ supports Atmos on Samsung’s native app, it should work even without eARC.

Another app you could test is VUDU. But you may have to purchase a UHD movie with Atmos audio to test it.

Or test Jack Ryan on Prime Video.

Now i get it to work on Netflix. 

It was a setting on The Netflix app that was wrong. 

So it dont work on Disney + 

Do you have a Netflix premium subscription? If so, try testing the film, Okja.
