Thanks everyone. Found it. On the main screen, I selected I/O Device. Then I picked IO. Then I selected #1 HA #1. At the bottom there is a graphical representation of the outputs. MIX 15 and MIX 16 were blank. I selected them. Then I selected ST L and ST R respectively - full sound in the mains. Again. Thank you to everyone who took the time to help me.
Glad it's working for you, but you need to realize what's happening. You are patching Dante connections in the console and not in Dante Controller. This is fine, and would be normal if you just had a console and a stagebox, but it is the clunkiest way to do it. Also depending on certain settings in the console, you may not save this in the scene. And if you DID save it in the scene, you may not recall it when you recall that scene. It all has to do with settings that are buried in the setup tab. All kinda confusing for a novice.
What Dante Controller does is gives you a nice graphical representation of what is going where. And it allows you to save that routing and recall it at will.
Fire up Dante Controller and save the routing RIGHT NOW since it is working for you. If this type of thing ever happens again you can recall the patch from DC pretty easily.
Digital snake to console patching is kind of difficult to wrap your head around, especially if you aren't a full time audio pro. There are several places to make or break a signal and all of them have to be right in order to get from A to B.
