Control4 configuration question - Sonos Port to Audio Matrix

Hello! I’m experimenting a bit with Roon as a potential workaround to the unfortunately awful interface between Control4 and Sonos. I have my Roon Core up and running and have added (and connected) the Core driver and a Zone driver to my Sonos Port (which I’ve enabled in the Roon Core.

What I’m struggling with is how the connections should run. I have several rooms connected to a 16x16 audio matrix with a couple Sonos Ports as source. What do I need to do for connections (bindings)?

Thanks for any help!
