Preview Member: Dolby Atmos output no longer works

johnsinclair96 · Mar 20, 2017

Since the last update i have Problems with the Dolby Atmos Bitstream Output. I can´t activate the Atmos Bitstream in the Settings. I select Dolby Atmos in the settings and will immediately link to the store to download a Dolby App. This Dolby App can unfortunately
not bei loaded in Germany. After this error is DTS Bitstream activated.

Does anyone have a solution and can helf me?

Thank you.

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...

Atmos Problem

I have a problem with Atmos. When the X1X is set up to output Dolby Atmos through my Denon AV receiver all Atmos titles from Blu-ray movies to Netflix work perfectly but everything else that isn’t Atmos is output as the lesser Dolby Surround even
titles that are Dolby Digital (which are most games and Blu-ray movies) are reduced to Dolby Surround, all Netflix titles that are DD5.1 are also reduced to Dolby Surround, however once I turn off Atmos in the X1X settings I get Dolby Digital displayed from
the other sources again on the Denon. Seems like Atmos is blocking Dolby Digital. Very annoying to keep changing settings depending on the content.

Is it possible that you set your sound output for headphones to Dolby Atmos and didn't buy the Dolby Atmos App?

If so, you will be able to try Dolby Atmos through Headphones for 14 days, after which it'll stop working.

You need to switch to basic Stereo or Windows Sonic if you want spatial 3D sound without paying for Dolby Atmos.

Since the last update, Dolby Atmos has stopped working and an undefined PCM data stream is being output.
All apps are affected, such as Netflix, Disney, VLC.
Dolby Atmos works with the Xbox sound test program.

Previously, Dolby Atmos had worked without any problems.
All other devices (Blu-ray player, mini PC, FireTV, AndroidTV, etc.) still work perfectly with Atmos on the Denon 4700X.

So after following up with the Dolby Access support team, apparently games aren't supported on home theater, only on headphones:

"Unfortunately, Games encoded with Dolby Atmos audio are not compatible with Dolby Atmos for Home Theater, as they are specifically configured for Dolby Atmos for Headphones. If the content you are experiencing is not compatible with the app you are
using, then audio will cease, or will simply output as regular stereo output.

To clarify, Dolby Atmos for Home Theater is included at no charge with any Dolby Atmos supported hardware, such as a receiver or Xbox One X, and is used to activate Dolby Atmos features via HDMI connection for a Dolby Atmos certified AVR, soundbar,
or TV."

"Unfortunately, the version of Dolby Atmos included with your Xbox is Dolby Atmos for Home Theater, which is not compliant with any gaming content."

It kind of strikes me as hard to believe, or that this won't be addressed, but that's what they're saying for now. That said, it still isn't working for me for Netflix content either, so I'm going continue troubleshooting with them and see what's doable
and what's not. Fingers crossed.

I just wanted to add that DTS:X works fine and is output with no issues. The issue is only with Dolby Atmos in the bluray app.
