Blu ray app won't play dolby atmos on UHD blu ray discs

I have this same problem. I'm not getting the Atmos Bitstream from UHD Blu Ray discs. Games aren't a problem and the demo videos from the Atmos App work fine, i.e. my receiver shows Dolby Atmos. But when I play a UHD Disk from the Blu Ray app, it defaults
to Dolby TrueHD. I'm pretty sure I've narrowed this down to an issue with the Blu Ray player App. The only thing I haven't tried, which I will tonight, is to uncheck the "Let my Receiver Decode" check box. Which shouldn't fix the problem, but I'll try it
anyway.

Do you have a Dolby Atmos compatible receiver, sound bar, or speaker system? If you do, have you changed the settings within 'Disc & Blu-ray settings' on your Xbox One to enable 'Let my receiver decode audio'? Currently Dolby Atmos is only supported within
the Blu-ray app for Dolby Atmos compatible Blu-Ray movies.

Keep us posted!

You can add me to the list as well.

Atmos had been working fine, then the other I day I was halfway through a UHD movie and noticed my receiver said TrueHD instead of Amos. Afterwards, I tried turning the pass through setting off and on with no luck. Then I tried the Vudu and the Dolby app
and both output in Atmos. Moved over to my PS4 and loaded up MI:5 blu-ray and the receiver played the Atmos perfectly. Took the same disc over to the Xbox and again I got TrueHD. I went so far as to delete and reinstall the blu-ray app with no luck. It's not
the receiver or the cable or the disc, so it has to be the blu-ray app, right? I really hope they fix this issue pronto. I got the Xbox One S specifically for UHD/Atmos.

I'm also having this same problem. The Dolby ATMOS app works great, VUDU UHD and Netflix 4k work fine with ATMOS, but when I have the Blu-ray app setting set to allow my receiver to decode (DENON S720W which supports ATMOS), the disc won't play - I don't
even get a downgrade, and have to change the settings back to disabled, and the disc will play with some other surround decoding. Occasionally, I can just keep retrying, and I will get Dolby THD. but NEVER the ATMOS that is on the UHD 4k disc.

I've tested this with John Wick 2, Suicide Squad, Wonder Woman, and Guardians of the Galaxy 2, and others as well.

I have an LG oled c7 and watch netflix trough webOs .

By doing it this way you should get Dolby Vision and Dolby Atmos.

Microsoft will roll out an sofware update for netflix Dolby Vision shortly.

For the moment Dolby Vision is not supported on the Netflix app via Xbox.

I hope they also update the blu ray player shortly because there is much more content available on 4k uhd blu ray.
