DTS Master Audio Transcoding Issue

[Kurozumi]

Hi there, have an issue with DTS Master Audio Playback in Jellyfin, first here is my setup:

-Jellyfin server is a docker container on my NAS
-Docker Container is pulled from jellyfin/jellyfin
-Jellyfin server version is 10.8.10 Linux/x64
-Playback device is a Nvidia Shield Pro 2019
-the AVR is capable of playing DTS MA and HRA

Don't know, what i'm doing wrong, i can't get the hires DTS formats to work, Dolby TrueHD and Dolby Digital Plus play as they should, DTS does not.
Transcoding is deactivated on the user, and the user info says "direct playing".

In the app settings on the Shield , the audio output is set to "direct", Dolby bitstream audio and DTS bitstream audio are both enabled. Preferred videoplayer is set to "exoplayer".

Hope that information helps for troubleshooting, if i use other apps (Kodi or VLC f.e.) to play the same files from my NAS, the audio playback works flawless.


Thanks very much
