Atmos not Working in Bluray App

I've had this problem for months but thought it was maybe something associated with original xbox one not supporting it but now have the xbox one x and same issue. Dolby atmos outputs as such in Netflix app and the dolby demo app but when I put a UHD disc
in the drive, bluray app seems to put out the sound as dolby digital when the disc has an atmos sound track. Is there something wrong with the app or is there a setting in the app that needs to be changed? I don't seem to have issues with anything else outputting
the sound other than the bluray app.

Atmos MKV Problem

It seems that the Movie&TV app doesn't have the proper Atmos Decoder for an Atmos audio track muxed into an MKV. So unfortunately, the only way to get Atmos is to use original BluRay discs with an Atmos audio track.

Bluray - Labyrinth 4K Blu-ray

I cannot get the Xbox One S to output Dolby Atmos to my receiver for this bluray.

The Dolby Atmos app samples on Xbox One work fine and receiver outputs Atmos.

This bluray only outputs Dolby TrueHD (not Atmos). Xbox set to Bitstream passthrough to Yamaha receiver and Atmos setting to home theater enabled but only TrueHD output.

Any ideas?

 

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.

 

I have the same problem outputting to Onkyo LS7200 Atmos soundbar, info on player shows Dolby HD even though disc is on Atmos soundtrack. Also I think the Atmos in game has echo on the surround channels which clears up if I go to DTS output from the sound
options on the xbox x . Overall not impressed.

 

I have the exact same problem. Xbox one S with an Onkyo Atmos Surround System (S5800). The reciever shows atmos when using the demos from the app and netflix, but not any of my atmos blu rays. I'm assuming this is a software issue with the blu ray app, so
I hope they patch it soon.

 

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.

 

I'm having the exact same issue using a Yamaha RX-V583 Receiver! Atmos works fine on all
apps except the blu-ray
app
