Apple TV 4K: No Dolby Atmos on Netflix, Only At iTunes Movies

I have exactly the same issue. I can add that the issue started after the update of the Apple Tv 4k to iOS 14.0 few days ago. It seems that the streaming of any multichannel video on Netflix app comes out in PCM 2.0, not just the Atmos ones. Streaming from iTunes Movies or Amazon Prime App is fine, I get Atmos or 5.1 as it would be. Also, with the same Netflix account streaming on an Android TV box linked to the same home theatre of the Apple TV (just different HDMI) I get no issue at all. All fine. Also on my Panasonic TV the naive Netflix app gets the Atmos signal right. It seems that this issue is related to an incompatibility between the new OS of the Apple TV and the Netflix app. Today I tried to de-install and re-install the Netflix app. Now, when accessing a series on the Netflix App I do not get anymore the flag stating the availability of the Atmos sound (just Dolby Vision). Somehow the App is fooled to think it is on a platform not supporting multichannel streaming. Called the Netflix assistance but they had not heard about the issue so far (but the new iOS has been released very recently). They do know however of other issues between the Netflix app and the new iOS. They might look into this if they will get several similar calls.

I had to uninstall Netflix and Prime then install it again to get my Onkyo RZ -820 to show that I was getting Dolby Atmos through my receiver again ....this all after the 2nd Apple tvOS public beta 14.2 that apple sent out...and there was a new public beta tvOS update yesterday 10/14/20 , which I installed and had no problems since....I hope all whom are having issues get them resolved soon...this has been on going for some time now ✌🏻

Don’t know what to say to help you. I am running 14.3 and have no issues with audio .

i did see this poster on Reddit:

Atmos not appearing in Netflix, tvOS 14.3

I have an Apple TV 4K running 14.3, and the latest Netflix app. It is connected using brand new HDMI cables to a Denon AVR-X3700H

Apple TV+ content in Atmos works perfectly

With Netflix, shows that I know are in Atmos are showing up as “5.1” in the app

Is there a fix for this, or is Netflix just super buggy with Atmos right now?

UPDATE: After reading through some other posts on this topic, it would appear that you just need to play some Atmos content, and then the app will update to show the correct content format

Netflix released an update few days ago which solves the issue.

Yep, I figured that out last night eventually, that the app seems to learn the capabilities of the ecosystem by playing a few streams first, which feels a bit buggy (it doesn’t do this with things like DolbyVision) but I can’t be sure that it wasn’t always like this. Prime also doesn’t state that the content contains an Atmos soundtrack but does work once playing.

That worked. It’s bizarre and clearly a bug but playing Atmos activates Atmos and eventually lets Netflix display Atmos on the pages of that content.

Apple TV new update 14.2 crush Dolby atmos

Yay update new version beta update fix my Dolby atmos on my Apple TV thank you 😊 happy 😊

Have you had any luck getting Atmos on any of these platforms you listed? I was planning to install my new Apple TV 4K although not feeling very confident Dolby 5.1 or Atmos will work with the Sennheiser Ambeo...

I have an Apple TV 4K. Brand new. Tv OS 14.3. Netflix will NOT play Atmos. If I switch back to the internal Netflix app on the Sony TV, Atmos is fine. Atmos working find on other apps on the AT4K So this is definitely not fixed.

Unfortunately this did not work for me. I’ve also tried to turn off Atmos and turn it back on. It works fine in the Apple TV+, Disney+, Movies anywhere, And really anything else that has Atmos sound. I am on 14.3 as well.

I have the same problem. Have you found a solution? Just started today!!

Here as well but Apple TV app works just fine
