Mark, thanks again for the tip above as well. However I am still trying to get past the "Assign Friendly Names to Audio Drivers".
As you can see in my attached .jpg of the drivers listed in Cakewalk Preferences, I started to name them with "Friendly Names" (I typed in Channel 1 as a friendly name to designate the first UMC1820 Driver 1), but then I realized that Driver #2 is not listed. The only place the Left, Right, Stereo Designation is listed is in the Track input and output drop down menus. I don't see any way to edit those designations. However as you see I could edit friendly names in the driver preferences menu in Cakewalk Preferences, but only the odd number drivers. How can I edit mono input names like Channels 2, 4, 6, etc.?
