Just before Christmas, I decided to proceed with updating my iMac OS to the Catalina.  I had held off since it became available out of respect for the things that could “go wrong” in terms of my day-to-day computer work.  Before the upgrade, Sonos Controller and my iTunes library interacted very well, allowing me to play albums, tracks, playlists, etc however I wished to play them.  Upon upgrading to Catalina, with its attendant introduction of the “Music” app vice everything audio-visual being stored in the iTunes library, my Sonos controller no longer can access the library to play anything.  Note that I do keep my entire iTunes audio-visual library on an external Lacie drive.

Interestingly, when I recently imported some new music from CDs, it did not get added to my external drive, but rather to the iMac’s HD under “Music”.  (I will be changing that default after this issue gets resolved.)  These tracks did show up when I added that folder to my Sonos controller’s music library.

When I looked at the iMac’s “music” folder, I saw a file entitled, “”Music Library.musiclibrary”, whereas the iTunes library had different title, with a “.itl” or “.xml” extension.  I believe that this could explain why the older music (pre-Catalina) cannot be played through Sonos.

I have uninstalled and re-installed the Sonos app, disconnected and reconnected my music library, gone through all the suggestions that I can find through this site and other internet searches, and I am now coming to you folks, the experts, for assistance.  I am frustrated having spent many hours trying to address this shortfall.  I cannot believe that I am the only person experiencing this problem.  Can you folks help me?

Note that the only way that my Sonos is anything other than a brick is when I play individual albums or tracks from the Music app via Air Drop - a very limiting approach compared to my pre-Catalina experience.
