Sorry to revive an old thread, but I’m running into a similar problem and it seems you might have the solution.
I’m running a couple Sonos Ports into a Triad Matrix via Control4. I’ve been able to add the Roon drivers to my project and have can see the Sonos Ports, but I don’t understand what I’m supposed to do for the connections / bindings.
Sonos Ports are in an equipment rack and via the Triad matrix they feed 8 zones of music. Any help is greatly appreciated!
