I’ve changed input 11/12 to be a stereo input. I want to change it back, so 11 and 12 are mono inputs. I can unselect stereo and confirm with OK, but input is not changed. Next time I enter the dialog where I can change mono/stereo, it it stereo again. ---

Hello there! There is unfortunately a display bug here that we’re aware of. If you make a stereo change, disconnect and reconnect to the AHM and it will show you the correct state. The bug is that the UI is not updating after making the change - the change itself is happening correctly, and reconnecting refreshes the view. ---

Hi MarkF. Thanks for the quick reply! I also figured out some minutes ago, that if you deassign the onput routing to those stereo channels, it suddenly works. Best regards, Dieter
