Newer Dolby audio (7.1, Atmos) not playing properly

[thedudeabides79]

I have Jellyfin installed on a Shield TV Pro.
But also struggle to play Atmos (5.1 and 7.1). My receiver (Denon AVC-8500HA) displays PCM.
Playing the same video on the same device, but than with Kodi, displays Atmos correctly.

If you have refresh rating switching on, then try turning it off.

That fixed it (I had it on "on TV").
However, now the video is 4K60 instead of the 4K24 that the movie is.

Is this a problem that i can fix, or something that is going to be fixed?

You can set the shield up to do the 24p you are trying to do. go into advanced video settings and set it up for 4k 24hz DV. I like having the refresh rate synced up and was doing it in jellying app, but it was cutting off my awesome jellyfin prerolls... This is what I am doing now and its working well. Hope this helps.
