I’ve had trouble with the Music Library in the past with S1 (since the latest Mac OS update). I finally got it to work by turning off the firewall and giving privledge to the Sonos controller (Security & Privacy) for the disk access.
Now….I noticed there is only S1 Apps available to choose. And there is something called SonosLibraryServer but no S2. The S2 app installed OK and works on other services but not my own music library (iTunes).
At any rate, I had to turn off the firewall again and although the S2 controller found all the music files and lists them, I get an error when it tries to play them (file not found).
I’m going to keep fiddling’ but if somebody knows the secret...please ring in.

Some good news I think
I had my Mac set up for both ethernet and WiFi. The ethernet for speed, and the WiFi for some device communication like my Apple Watch.
I upgraded my Nest WiFi mesh network to Gen 2 as our ISP is upgrading our Internet speed from 70/15 download/upload Mips to to 250/250. Now, the WiFi will be blazing fast and I don’t need the ethernet anymore.
I changed the Mac to WiFi only and magically I was now able to add the Music Library in Sonos without a hitch. That was the only change to the Mac that I know of. Must be something there that Sonos doesn’t like about the dual connection. Come to think of it, I think my troubles started about the same time I got my watch.
Anybody else have their Mac set up for both wired and wireless?
