BUG: With Dolby Atmos activated, all apps used Fallback to PCM 2.0

Greetings:

I recently got the Xbox One S, updated it to latest Firmware and installed the Dolby Access app.

BluRay in Atmos/DTS:X works fine.

Games work fine (fallback to linear PCM 7.1)

Apps have problems. Mixer, Netflix, even the normal UI all use the wrong fallback if there is no Atmos signal. They use fallback to PCM 2.0 (since Netflix, Mixer and so on don't output sound as 5.1 or 7.1 Linear PCM). If I set the Console to Bitstream Dolby
Digital (instead of Dolby Atmos) then apps correctly stream 5.1 DD Audio as expected.

I'm using Dolby Atmos for Home Theathre via HDMI btw.

I wonder why this hasn't been noticed during Preview testing!

What should happen:

Dolby Atmos Content -> Dolby Atmos Bitstream

Dolby Digital or Dolby Digital + Content (Apps, UI) -> Dolby Digital (+) Bitstream

Linear PCM Content (Games) -> Linear PCM 7.1 Output (or Dolby Digital if selected)

What currently happens:

Dolby Atmos Content -> Dolby Atmos Bitstream

Dolby Digital or Dolby Digital + Content (Apps, UI) -> Linear PCM 2.0 Downmix

Linear PCM Content (Games) -> Linear PCM 7.1 Output

I hope I explained the error conclusively and that we will soon see an Update to fix this very annoying issue.

Thanks.

Btw...is there any information yet, which games will be Updated to actually work with Dolby Atmos? So far there are none...

Audio settings totally screwed up on XB1S

I have the same issue since the latest alpha update that was released October 27th. Before I had bitstream out and dolby Atmos. Now only 7.1 PCM.

But my blu rays are working with dolby Atmos. I hope this get patched with the next update.

 

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.

 

Hey Commander,

As we can see that you're currently a Xbox Insider, please be sure to report this through the Feedback app if you haven't already, as well as checking in to our

Xbox Insider forums. That will be the most effective route to take for this specific issue as those reports get routed to the appropriate team to look into.

 

Same problem here with my Denon X3200W. Displays Dolby Surround (receiving a 2.0 signal) on everything except the Atmos app (Which shows as Atmos on the receiver)

 

I'm curious about this issue, too, because when I first downloaded the Dolby app, if you remember, there was an issue with bizarre static when choosing ATMOS as the output (at least, it was doing that for headphones.) At that time, in the setup, there was
a checkbox in the Xbox Settings app which said something to the effect of "enable virtual surround in apps." After this static issue was fixed, I noticed that the checkbox for surround in apps was no longer available. I wonder if this was disabled because
it was somehow contributing to the static, and also, if that means it simply isn't outputting surround sound when using an app vs. a game....

 

That's a different issue as it only refers to Headphones. Atmos Bitstream is only for AVRs. The Virtual Surround checkbox was removed because virtual surround is now always on.
