QUOTE from point 4: *** NOTE: Leave Speaker Management to OFF. If you select any other choice and "then" back to OFF, this will "MUTE" Mix 1/2 and Mix 3/4, which could explain why your Line Outputs 1-4 will not pass audio.
How do I get back to a situation that I can decide what to send to Line Outputs 1-4?
I was using Studio One, and have two stereo signals routed to Outputs 1,2 and 3,4 via Two Stereo Sends. It worked.
After trying out Speaker Management, I can't make it work again. The send receive sound but don't seem to send it to the speakers.
