Sonos Arc + AppleTV + Samsung TV = No Dolby Atmos

My tv is a Samsung QN85QN90AAFXZA. It’s less than a year old and has eArc. 
Hooked up the Arc and 4K AppleTV but don’t get Dolby Atmos showing during playback in the Sonos app…  It reads “Multichannel PCM 5.1”

Known issue?  User error?

Any help would be greatly appreciated  

Thanks!

How old is the Apple TV? It needs to be one of the newer ones to support Atmos/ Dolby Digital Plus. Might be worth double checking that your Apple TV supports these formats, especially if that isn’t appearing as an option in the settings. It is running tvOS 16.0 (20J373)?

Nothing on either the tv or AppleTV indicating DD+

This is frustrating…When I bought this tv I specifically made sure it supported eARC pass through. Now that doesn’t matter. 

Well if the TV does supports DD+ then you should be fine, albeit I couldn’t see that codec mentioned on rtings.com for that particular TV - I would have expected the Apple TV to show ‘immersive audio’ aswell, but maybe check with Samsung support desk and see what they might suggest.

@Clemdog,

As another thought, If you play a movie from the TV in-built Apps (such as Netflix - 6 Underground movie) do you get Dolby Atmos from that App?

Good thought. No luck however…

Ensure your Netflix subscription is ‘Premium UltraHD’ in order to get Atmos via that App - if it is …and the TV Netflix App is not supporting Atmos audio output, I would be thinking the TV is not supporting the Dolby Digital Plus codec, but definitely check that with the Samsung Support Staff and see what they say.

Interesting thought…. Are you saying that the older 4K AppleTVs potentially won’t work with my setup?  Let me check that out.

Yes. I’ve got the most expensive tier of Netflix.

Probably the 4K Apple should have it, assuming their software is up to date, but likely older versions wouldn’t, since they pre-date  the release of Atmos, and may not have the hardware to support it.
 

The key thing in my mind is Ken’s suggestion about the audio settings in the Apple TV itself. You’re stating it doesn’t appear, which is concerning, on both of my Apple TV 4K models, it does. So either the hardware could be too old, or the OS running on those devices might be out of date, in my opinion.

We have a winner!!

I swapped out the AppleTV with a newer one I had in another room that was purchased just a couple of months ago. 
Now the Sonos app indicates Atmos!

 Thanks to all for your help with this.

So here’s a follow up question unrelated to Atmos. 
When I raise or lower the volume on the Arc there’s a visible indication on the screen. Anyway to make that visible que go away?
