Test-SetUp wegen echtem(!) Audio Passtrough (truehd 7.1/ dts hd ma 7.1) bei movies:
NoteBook HDMI 2.0b --> HT-A9 HDMI Port --> HT-A9 eArc TV Port --> HDMI eArc Port 3 A95L

There is no output from Digital Audio Out (Optical) when watching video from an external device connected with an HDMI cable
The audio signal from the HDMI® input passes through the TV when eARC is enabled, so there is no output from DIGITAL AUDIO OUT (OPTICAL). This is normal operation.
Warum ist das eine 'normal operation'?!
PS: am optical vom A95L ist ein HighEnd-iges HiFi System im Stereo SetUp (hat kein HDMI)
