Xbox One Series X - Dolby Atmos Audio Lag issue?

Hi RomiDumitru,

*maybe* this "problem" is exactly how the Dolby Atmos App on Xbox One X works.

Dolby Atmos native content? perfect! Dolby Atmos playback.

No Dolby Atmos? the App upmix current audio track to Dolby Atmos (the headphones features works in this way).

I don't know if is intentional.

Geri,

I have the same issue on my Xbox Series X. Audio passthrough works perfectly fine with Disney+, Amazon Prime and Plex. When it comes to Netflix, it doesn't activate passthrough creating audio problems while playing Atmos content. The titles display Dolby Atmos, but there is no voice, only background music and sounds are played.

Hi,

unfortunately the series x doesnt have an optical audio out port so that is not an option - and that also doesnt solve the issue which is specific to dolby atmos.

So according to the manual for the panasonic soundbar i need to run two hdmi cables from the xbox - one to the tv for dolby vision/ALLM and then a second one to the soundbar for the sound

Obviously theres only one HDMI out socket on the series x so i assume this is not possible?

My Xbox One X is connected to my receiver. When I try to setup Atmos in the audio settings Xbox One X says that my receiver, Denon AVR-4300H, does not have Atmos capability. I am only allowed to choose DTS for the bitstream sound output. Atmos works fine
with my Samsung 4K player so I know it is an Xbox One X issue.

The Dolby App does not give any error until I try to view the demo videos where it flashes, "you are not viewing this video on Dolby Atmos." It plays the demo video on DTS instead.

***UPDATE***

I finally got Dolby Atmos to work!!! Under "Settings, Display & Sound, Volume, Setup TV & AV Control, Audio" I had to change the default "Stereo" setting to "Surround Sound." The Xbox One X had to reboot to accept/change the setting. Once it rebooted Dolby
Atmos was working. It is interesting that the main control will be under the volume settings instead of audio output. You would think the system will be smart enough to activate surround sound when you are choosing Dolby Atmos to bitstream.

Hopefully this "difficult to find" change of setting will work for others who are having Dolby Atmos issues.

Issue has been reported multiple times by many people as indicated in this and few other threads (reddit, xbox forums, etc). I myself have opened several tickets (currently have one ongoing now) on the issue and yet it still hasn't been resolved. I have also created help tickets with Dolby Access Support, and their responses continue to be that it is a Microsoft issue in how it is outputting Dolby Atmos. Summary of my issues is below:

- Bitstream audio out no longer an option in the HDMI output settings. In the November 2021 update on the Xbox Series X, the audio settings page was changed and unfortunately the option to output bitstream audio was removed. Despite the many issues this has caused, Microsoft still has not fixed the issue. Please bring back the bitstream/lossless output formats instead of forcing PCM only.

- Despite Dolby Atmos being selected as shown in the picture, the Xbox is outputting PCM 'multichannel audio' instead of Atmos (receiver display shown in lower portion of picture). This appears to be causing delays/hiccups in the HDMI handshake process as whatever PCM signal is being sent is not fully correct and the receiver bounces between seeing multichannel audio and dolby atmos until finally settling on multichannel audio. To my earlier comment, being able to pass true bitstream dolby atmos audio to the receiver should eliminate this issue.

- I have the Xbox Series X running to the AVR and then to the TV in order to have access to all the audio formats. When I tried to run the Xbox directly to the TV and then audio over eArc to the receiver, the Xbox will only output PCM Stereo, Dolby Digital or Dolby Atmos. I have tested the TV/receiver and they are able to pass other formats (such as DTS:X) over eArc so it is an Xbox issue of not allowing all the formats to be output (possibly related to bistream vs PCM also?).
