I've installed Kodi on my Xbox one X and have installed the add-on plex... i've enabled the passthrough for audio on the plex app but i'm not able to see the option to enable the passthrough on the Kodi App (expert settings).

When I play TrueHD 7.1 4K movie it transcodes to ACC Stereo 

Not sure what i'm doing wrong... as others have posted the instructions and they are able to get to passthrough for audio to work.

Also side note i'm suing 5.1.2 speaker setup on a onkyo receiver which supports 4k and Atmos

From the Known Issues post - 

Passthrough audio not working - Not supported by Microsoft for 3rd party apps
