Atmos App Sound in game lower recently?

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.

I also re-installed the dolby acces app. Demo content in the app itself plays sound from my height speakers and the rest of my speakers. I only get this problem when playing games, where only the height speakers are not playing any sound at all.

It seems that the console and your audio system is properly configured for Dolby Atmos, since the Atmos Demo works.

Also try to download the free "Insects" demo from Microsoft, which allows you to switch between Dolby Atmos and "regular" surround sound.

Check if Atmos works in that demo, as the Atmos Demos in the app are usually videos with a fixed, pre-rendered audio track.

Also, which games are you trying exactly? Do the games really support Dolby Atmos themselves? Because the Xbox One S will not "upscale" regular surround sound from non-Atmos games to have height information.

My lg Dolby atmos sound system shows everything in Dolby atmos, I know there has been a issues with the app.

But I agree not every game supports Dolby atmos 👍

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.

I recently upgraded my sound system and am facing the same issue. I can however stream Netflix in Atmos from PC without the pops and artifacts. I would much prefer to use Xbox. What I do notice is using Netflix app and setting Atmos up through the Dolby
Access app on both you would expect similar performance from both via hdmi into the same receiver HOWEVER , the Atmos stream from PC is around 10db lower volume than the same stream from Xbox, as in to get the same audible volume, both on atmos I have to turn
up the amp 10db on PC vs XBOX. This makes me wonder is the xbox issue caused by digital clipping because it for some reason is outputting at a higher gain than it should? I don't understand why there is a volume difference between apps on the 2 microsoft operating
systems.

Have you had any response or resolution so far?
