DOLBY ATMOS XBOX A DENON NE FONCTIONNE PAS [Mod Translation-DOLBY ATMOS XBOX A DENON DOES...

Hi tropikalam,

Thank you for posting on the Xbox forums. I'd be happy to help troubleshoot the issue to start narrowing down the root cause. Give the following steps a try. While the Xbox is on, go ahead and do a hard
restart and power cycle to the console. Hold down the power button on the console for about 10 seconds or until it shuts down and then remove the power cable from the Xbox and the power outlet for about 5 minutes. Then re-connect and wait 60 seconds
before turning on the Xbox. Holding down the power button on the console to force a shutdown is an important step.

If that doesn't help then you will need to try out a soft factory reset.

1. Press the Xbox button on the controller to open the guide.
2. Scroll to the right and select System > Settings > System > Console info.
3. Select Reset console.

Make sure to select "Keep my games & apps" and have the correct account login information plus your Wi-Fi password ready if you connect wireless because you will need to re-add the accounts that were on the Xbox and re-connect to your network during the
reset.

Let us know how it goes!

Very popular receiver, have one too. No atmos for game support and Arcing atmos back introduces too much latency.

Apparently the issue rests with microsoft as Denon has updated the firmware to anticipate the new, updated version of Dolby atmos home cinema for games or “low latency atmos” so it’s called. The One X supports the regular cinema profile.

Dolby Vision and Atmos are now fairly fragmented formats, makes me wonder if Microsoft should ditch them and go DTS:X moving forward.

First: Thanks for the info! You gave me more info than DENON, XBOX/Microsoft, and Dolby combined!

Secondly: Where did you find that info? As DENON, XBOX/Microsoft, and Dolby seem not to know!

If Microsoft goes with DTS:X, that fine, as long as they keep Dolby Vision. Our DENON’s can handle it! :^)

Thanks again!

If you could guide me towards that info, that would be groovy!

I have had the same issue with Netflix and Apple TV (a few months), no Dolby Atmos, although there is a label Dolby Atmos at the title and chosen track with Dolby Atmos in the application. My AVR shows a PCM input signal for this application.

My setup is: Xbox Series X - Denon AVR X3700H - TV Samsung 75Q80T

After a lot of test, to solve it i plug xbox on my lg cx with option sync AV arc bypass and activate earc with my denon 1600h.

If earc is off there is a big audio delay but my denon receive an atmos emulated (pcm) for all game, If earc on no delay atmos OK on halo, forza etc... But no atmos on ubisoft game same as farcry 6.

Ubisoft game not really atmos but a dolby 7.1 sound ?

My conclusion If xbox use dolby atmos emulation or no earc there is a delay, if earc activate no delay but only atmos with game compatible

I can confirm this bug with the Dolby Atmos app.

My setup: Denon X4200W receiver with Xbox One S.

Atmos works fine in the Dolby Atmos app, Blu-Ray and Netflix (the movie Okja is the only Atmos movie on Netflix). All other Netflix videos and Xbox apps default back to 2.0 down mix as posted above.
