Dolby Atmos not working on Xbox One S anymore

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.

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.

I have the problem that Netflix Dolby Atmos is not working with the x box S, if I try to play a series with Dolby Atmos, then Netflix give the text:

This title can not play try later?

Configuration is ok at the x box s and all other content without Dolby Atmos will play correct.

If someone have a solution?

A secure Dolby Atmos format, both on one s and one X

This is Xbox One specific, and relates to how Dolby Atmos capabilities via Home Cinema amps. They have been compromised by the fact that the Dolby Atmos app version has not kept up with the firmware of numerous current amps from multiple brands.

Since August, it changed from outputting Atmos signals as "Atmos" to to generic "multi Ch in".

Like many others, I mailed Denon, and it is an issue relating to the MAT container embedded in the Dolby Atmos app. We collectively need a definitive answer on when Microsoft and/or Dolby intends to upgrade to 1.6?

The full quite of the Denon explanation is below:

"Dolby Atmos version is changed from “Dolby Harmony 1.3” to “Dolby Home Audio 1.6” via U21 Update. The Dolby Home Audio 1.6 includes the “Dolby MAT signaling” feature that detecting the channel based PCM signal contained into the Dolby MAT Container.
And, major player which contains the PCM signal into Dolby MAT container is only XBOX One S and XBOX One X, currently. With new Dolby Atmos version 1.6, specific processing of source (XBOX) is needed. This is now the problem: Xbox did not implement this processing
yet:"
