Mac user here. My desktop is an iMac running Monterey 12.2.1. My music library is on a Mac Mini running Sierra 10.12.6 which I have not yet upgraded because it works fine for what it is supposed to do.
Anyway, I recently started ripping some new CDs using the program XLD. I now have a folder on my iMac desktop full of FLAC audio files. Using the Sonos Mac app, I have added that folder to my Sonos music library which sees the folder but sees no available files inside that folder. Specifically, when I open that folder it says “No selections are available.” Sonos does see the iTunes and Music libraries on the iMac and Mini and the files within them.
So my question is, does Sonos need to be specifically pointed at a library and not just a folder of audio files?
thanks in advance for any help/advice,
