Dolby Atmos Problem bei 4K Filmen

I have the same problem on Xbox X and XBox One. I’m using the Denon AVR-X 2700H 7.2 channel Dolby Atmos receiver with the XBox X, and the Yamaha RXV-6A 7.2 channel Dolby Atmos receiver with the Xbox One. Both receivers were working normally outputting Atmos on Netflix until November 2022. Disney+ and Amazon Prime play Atmos content on both devices without issue, hence indicating that the problem is not with the 4K TV and 4K projector, nor receivers.

Hi RomiDumitru,

first part of the problem, Dolby Atmos missing in TV Netflix App: the reason why Netflix App on TV don't recognize Dolby Atmos is simple, the TV don't support it, only latest Samsung 4K Q series (like Q90R) have pass trough for ARC HDMI and Dolby Atmos (not
direct support, only passthrough), and the latest Soundbar (again, Q series) support it without any issue (this latest SoundBar have also a Built-in Game Mode to reduce as much as possible latency).

For example I have a Samsung Q9FN 55" (top 4K Samsung 2018) and no support for Dolby Atmos.

So, as you understand perfectly, the best option is to connect the console (and any other device you desire) directly to the Onkyo 7.1 ampli.

Now the second part of the problem, all upscaled to Dolby Atmos by console.

For this I can't help you because at the moment I have only Dolby Atmos for headphones and is obviously an upmix, a virtual multi speaker on a stereo headphone.

I don't know how work the Dolby Atmos app on console for the multi speaker system, the only idea I have is to try open the App and search for any setting, maybe you can find one to disable the "always upmix to Dolby Atmos" and switch to something like "play
in Dolby Atmos only Dolby Atmos native content".

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.

It seems that your TV supports Audio Return Channel (ARC). However, on the TV's specification page I don't see if it supports Dolby Atmos through ARC.

If your TV is capable to send Dolby Atmos via ARC, you'd connect your Xbox to a 4K capable HDMI port OTHER than the HDMI ARC port on your TV.

You will then get 4K resolution on the TV screen, and the TV would "forward" audio via the Audio Return Channel to the sound bar. If supported, this will then be Dolby Atmos.

It seems that the Soundbar doesn't support 4K pass through. So either you would need a new TV that supports Dolby Atmos via ARC, or a new soundbar or AV receiver that supports 4K video.

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?
