Dolby Atmos signal not picked up with Samsung QN90B

Have just set up my new Samsung QN90B TV. My Sonos Arc is connected via HDMI eArc. I have opened a Netflix stream with Dolby Atmos through the TV native app. On the Sonos app it is only showing a Dolby Multichannel PCM 5.1. I am not 100% sure but I'm sure that this doesn't have Atmos signal.

Any idea how I can tweak settings/etc. to receive Dolby Atmos signal. 

Cheers

And last time I checked, all YouTube content was in stereo, and not Dolby Atmos.  Or Dolby Digital, for that matter.

Just checked and sorry you are correct,i have standard package which doesn’t include Atmos, just me being dumb.

Any other ideas how I can try testing dolby atmos signal?

Guessed that might have been the case for Youtube.

If you have Prime Video, test the film The Tomorrow War or the Jack Ryan series.

 

You might be able to download these Dolby Atmos files onto a USB flash drive and plug it into your TV to play the files:

You can start a Amazon Music Unlimited free trial and play Dolby Atmos music directly from the Sonos app. Here are some good songs/albums to test:

“Rocket Man” - Elton John

“BOOM” -  Sevenn and Tiësto

“Riders on the Storm” - The Doors

Don’t Know Why (album) - Norah Jones

Automatic for the People 25th Anniversary Edition (album) - R.E.M.

The Future Bites (album) - Steven Wilson

John Williams in Vienna (album)

3-D The Catalogue (album) - Kraftwerk

There are some videos on YouTube available in 5.1 now. The 5.1 audio doesn’t sound great, but it’s good to see that YouTube is making progress with multichannel content.

I’m not sure 5.1 on YouTube is supported on all devices though. It works on my Roku Ultra and Apple TV 4K. NOTE: You may have to change the audio settings on the video:

Both of these videos play as “Dolby Digital Plus 5.1” for me.

Hi Everyone,  I’ve connected Sonos Arc to Samsung QN90C Neo Mini QLED eARC HDMI port.

In TV, Settings > Sound > Pass Through is greyed out. Dolby Atmos is also greyed out. I’ve gone through all the above comments and tried all the solutions. Still these settings are greyed out. What could be the reason?

 

I’ve played Jack Ryan from Amazon Prime Video which is in dolby atmos but it’s showing as “Dolby Multichannel PCM 5.1” in sonos app

 

All the other videos played in TV(Netflix/YT/Prime Video) are shown as “Stereo PCM"

 

I think i am using HDMI cable is HDMI 2.0. Is that the issue here? Do I need HDMI 2.1 cable?

For sound no cable above 1.4 spec is needed. If you are using the apps on your TV it is strange that you would get PCM because as far as I know all apps send out Dolby Digital. So the question arises what t(e sound settings on your TV currently are.

You need to be playing a 5.1 or Atmos source before you are able to change the TV setting to Pass Through.

Also, most YouTube videos are only available in stereo. And you need the “ad-free” paid subscription to Prime Video to get Atmos audio.
