AR MK1 no Sound from Analog Voice

I can hear sound from the sample in that channel i.e. if i load a snare on the snare channel - i can listen to it - but i cant hear the analog voice. I created a new project to verify - but its the same behavior here.

I did run a analog calibration now. OS 1.61 E is freshly installed. (most recent one to work with overbridge.) Its not stated in the upgrade process, that this would be necessary.

Worked after calibration, i didnt have it on my table for a while after getting the Syntakt.
