yes, the lights are working; I fly such planes for FSX and with a complex system deep in legacy mode. Only the sounds of switches and seat belts/no smoking were not to hear. I looked in the sound.ini and it looks like that there:

SoundOffWhenSimIsSlew=1
SoundOffWhenSimIsPaused=1
SoundOffWhenSimDialogIsOpen=1
SoundOffWhenSimSoundIsOff=1

I put all of them to zero, tomorrow I'll check if the sounds are back again.

A first resumee: the plane works very well now! Superb starting, cruising and autolanding. Autopilot makes no problems at all and the performance is very well too, even in P3Dv2.2.
