My Xbox One X will not pass HDR or Dolby Atmos to my Pioneer SC-LX904

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 have a Vizio 65 4K HDR TV with an LG 9 sounder with Dolby Atmos. Used an HDMI connection for Atmos sound and nothing. Is it my sounder or my X or is it a software issue between the X and Dolby?

i think you guys must add on xbox scorpio , 4k hdr bluray player, dolby atmos, dts x, sound

Update:

I have now tried a 4K Blu-ray disk and can confirm that Dolby Atmos works with it. I used the AVR Key so HDR would go to my LG OLED TV and the Dolby Atmos Sound would go to my non-HDCP2.2 Marantz SR7009 Receiver. I now believe the problem is with the Dolby
Access App and not with the Xbox One X's operating system itself since the 4K Blu-ray would send its own Dolby Atmos track to the receiver bypassing the Dolby Access App. Where with Games and the Demo's in the Dolby Access App are using that App to process
the Dolby Atmos signal. Thus I believe it is a problem with the Dolby Access App, but i don't know how that ties into the operating system or how the Blu-ray player app integrates with the Xbox's operating system or bypasses it because of that pass-through
setting that lets the receiver process the Atmos Signal. Either way I have concluded there is nothing more I can do, it's definitely an issue with either the operating system or Dolby Access App having compatibility issues.

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.
