Many thanks. I’m not able to set up the Shield TV to playing Atmos. Neither with Kodi either with Plex.
With a cheap media player from China Atmos was running.
In Kodi I have put the settings in «HDMI Passtrough». In the Shield TV I don’t have any possibility to
set «HDMI Passtrough» or «Bitstreaming”. I tried to set "Settings > Display & Sound > Advanced > Fixed Volume"
but it doesn't help. With "fixed Volume" or without the AVR is allways displaying "Dolby True HD" insteas of "Atmos".
I also tried to set up the Shield in the "factory Setting" and different HDMI cable.
I’ have the Shield 2017 with newest update 6.3
