Alpha skip ahead: Dolby Atmos - All sound from rear for Netflix / Disney+ / Dolby app....

I have a Samsung Sound Bar with Dolby Atmos. All works fine on the Xbox One X with Netflix, Amazon Prime, gaming and the Dolby Atmos app. Doesn't work with the Disney Plus app though. Sound isn't coming through the rear speakers and sounds very ordinary.
I go and do the Atmos tests and demos on the Dolby Atmos Xbox app and they work and sound awesome.

I've googled around and apparently lots of people are having the same issue with the app. Hope they fix it soon as I was planning on watching the Star Wars trilogy in 4K and Atmos. I'll wait until they fix it.

Since the last update, Dolby Atmos has stopped working and an undefined PCM data stream is being output.
All apps are affected, such as Netflix, Disney, VLC.
Dolby Atmos works with the Xbox sound test program.

Previously, Dolby Atmos had worked without any problems.
All other devices (Blu-ray player, mini PC, FireTV, AndroidTV, etc.) still work perfectly with Atmos on the Denon 4700X.

Hello!! I'm in the alpha skip ahead. With the last build the problem is fixed. Now it's multichannel in the dashboard, when you load an atmos game the display will change in atmos. Same for netflix.

This is fantasic news! Thanks. So just to be clear it seems that Microsoft solved it? Or did Dolby Access get an alpha update?

Thanks for your reply, but that has obviously not resolved the issue.

I've done a few tests regarding the apps.

When the CX has eARC on and Digital Sound out set to passthrough and Allow Passthrough setting is ticked on the XSX, the sound bar is not recognised as an atmos capable device, but Netflix, Disney+, blu-ray player and the Dolby Access app all send atmos signal to the soundbar with no noticeable delay. No atmos sound in the XSX menu or in games is able to be played only the other sound format (not DTS-X though).

When the CX has eARC turned off and digital sound out set to passthrough the XSX recognises the soundbar as a Dolby Atmos capable device. The soundbar then receives atmos audio, however delays are now introduced in everthing mentioned above apart from the Dolby Atmos app. The sound delay in this situation, seems not as bad as when the the CX has digital sound out set to auto.

When the CX has eARC turned on and digital sound out set to auto the XSX recognises the soundbar as a Dolby Atmos capable device, however everything has a delay introduced. Strangely Netflix and the bluray app seemed the least affected, but the Dolby Access app and Disney+ it was quite noticeable and in games it was worst.

Hi

I have the same problem like you. I have an Xbox One X connected through HDMI cable to an Onkyo amplituner 7.1 which is capable to decode Dolby Atmos & DTS X.

I have installed Dolby app on my Xbox to get Dolby atmos sound and the result was that I have on all the games no matter if these are with sound in Dolby Atmos or not only in Dolby Atmos.

Is very strange to get that. I have supposed that when I buy a game with sound in Dolby Digital 5.1 to have Dolby Digital 5.1 and when I buy games in Dolby Atmos to get Dolby Atmos in my amplituner Onkyo.

The same problem I have with all the movies from Netflix. I installed the Netflix app on my Xbox One X and now all the movies I see have sound in Dolby Atmos, even if in the name of the movie on Netflix it is said the sound is recorded only in Dolby Digital
5.1.

What to do in that situation ?......I have tried every settings on my Xbox without any result.......When I put settings on output sound in Xbox everything I played is all in Atmos.

Like you said: "We don't need everything to be upscaled to Atmos, we just want Atmos to work on stuff that is Atmos as it should!"

Thanks in advance for everybody give me every piece of advice

Romeo.
