Audio passthrough only works when switch on/off – Nvidia Shield

Hello almighty forum,

Switched hardware from RaspberryPi 3 to a Nvidia Shield v2 and i have some issues with audio passthrough. Can’t find any threads with the same issue.

My hardware:

Nvidia Shield v2 fw:
Kodi version: 17.3 Git:20170524-77575

Marantz SR7010
Latest fw. (0992-7370-9285-04.)

In kodi system audio settings i have set audio passthrough to enabled. When playing a movie with any format i get no sound what so ever. The receiver identifies the signal as “unknown”. If i then while playing the movie go to the Audio and subtitles settings menu and disables the Allow passthrough and then enables it again i get sound and all works as it should. The receiver identifies the signal as “DTS-HD” or whatever signal the movie contains. I have to do this every single time i start a movie to get sound.

Any suggestions on how fix this behavior?
