Martin, I’m not sure how to explain the slight differences in the naming of my inputs for Audio 01 and Audio 02. I’ve set up another test where I was careful to have the inputs appear exactly the same way. I’ll attach a screenshot showing the Audio Connections > Inputs, and another screenshot showing the dropdown menu choices I get when I select the input routing for Audio 01. I get the same choices for Audio 02. It’s strange to me that I’m given the choice of stereo inputs when I have selected all mono inputs in the Audio Connections menu.
No matter what selections I make, the result is still the same: The signal going into Audio 01 also shows up on Audio 02 *unless I pan the Audio 01 fader hard left.
