Samsung TV on OH2 Docker Container


after perfect support for my Denon which now runs flawlessly.
I connected my UE46D7000 it was automatically recogniced.
The only button working is Power off.
I am playing at the moment with different home automation servers and on another one is mute and volume increase/decrease working.
So basically it should be possible. Is there a config file where I can try anything?
Any more ideas to improve it a little?

Big thanks for your help.
