Dolby Atmos and 4K

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?

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.

Xbox can play 4K HDR dolby atmos on videos. Just make shure to enable it on your console settings/display and sound/video output/video modes and check allow dolby atmos.

Hope this help dear sir. Let us know the results.

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".
