Thanks, George.

No that didn't work. Analog volume is still controlled by the volume knob. (While my pair of 3100s correctly isn't volume controlled any more.)

But I found out that the analog output is fixed when I choose "Analog MCh" instead of "Analog 2Ch" in the application setting via OSD. I further configured main large analog as only speakers. So basically a multichannel analog setup with only two speakers configured.

That works fine for stereo material. Even DSP is "disabled", just like in the "Analog 2Ch" application setting.

But for DVDA I only get the main left and right channel to my headphones. It isn't downsampled to stereo.

Listen to DVDAs with headphones would be cool.

It seems that I'm trying to use my G91a in a way not intended by its designers ;-)
