@gurabli,
I checked it and it seems that you can configure via automatic switcher "only":
- device
- passthrough y/n
- channels
So adding "stereo upmix y/n" to the automatic switchable attributes would be great.
Or another idea: the combination with the addon "Audio Profiles" would also be good.
Defining the audio profile for music and video via "Audio Profiles" and do automatic switching via "Automatic Audio Switcher".
Just dreaming.....
