Atmos mode has no/very faint surround on non atmos content

Dolby Surround is a upscaler from a not atmos source like 5.1 or 2.0 to surround with use of al your speakers like 5.1.2 or higher.

dts neuralx is the same upscaling system from dts

You had no problem with atmos, you think you had.

Now with the new firmware update the xbox one x is a broken thing with netflix

With a non atmos source the receiver must do the upscaling but now the xbox puts out a 2.0 or 5.1 stream in a atmos package, and no sound is comming out your atmos speakers.

I have the same problem, but my Xbox One X pushes Dolby Atmos to non Dolby Atmos movies. Also my Xbox pushes out HDR to non HDR movies. It's very frustrating that the sound cuts in n out even when I play Shadow of The Tomb Raider that's Dolby Atmos. Even
Avengers Infinity War sound cuts in n out. Since I have a Geek Squad warranty, I took my LG SJ9 to Best Buy. They tested all Dolby Atmos scenarios and never once did they have a problem with the soundbar in Dolby Atmos mode cutting in n out. There's something
wrong with the Dolby Atmos signal the Xbox One X uses that the SJ9 has problems decoding.

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.

I am experiencing this as well. Everything comes across the av receiver as Dolby Atmos, even non-Atmos content. Previously the receiver would switch as needed.

Yes i have the same problem with the one x with netflix.

The atmos logo is always on in the display but there is no sound from al the speakers with a 5.1 or 2.0 source.

With a non atmos source the receiver can upscale with dolby surround or dts neural x so it must be.

Blu ray works fine without atmos pushing so the receiver can do the upscaling.
