I have a SONOS Playbar, and am running SONOS 2 controller for Mac.  Version 12.2,  Sonos OS  S2,  Build: 61182310  Sonos ID: 114287825.

My problem is that I can not establish a connection to my Music Library(iTunes Music) on my iMac without getting an error message.  Therefore I cannot play music. The music library does NOT appear in window, and the error message states:

Sonos was unable to add the music folder

Access to the shared folder ‘//Michaels-iMac/Music’ is denied - check the username and/or password.

Last week I called the Sonos technical support and attempted to resolve this problem  for over an hour to no resolution.  The Tech elevated this problem to a higher level and he sent me an email to establish an appointment.  My appointment with higher level Tech resolved the problem after several minutes, with this Tech accessing my ‘screen’ and typing in the path to my Music Library which established the connection and I could see all of my playlist and music.  

The remedy to my problem was short lived however as the problem re-established itself after the computer was turned off.  After turning my iMac back on, the Sonos OS lost the connection to my music library and the same problem started again.

I can play music utilizing the Sonos Radio as well as Tune-In Radio.

The most interesting fact regarding this problem is that I have three accounts on this Mac.  My account,  my wife account, and an account I call Testrouble which is an Administrative account that i use to attempt to test and remedy problems like this one.    When I attempt to use Sonos to play music under this account my music appears normally, and plays normally as well, however when I go to Manage>Music Library Settings and the window listing the Music Library is COMPLETELY BLANK.

What is happening here?  Why/how does my Music play, whether I queue it up from the main list or from  any of my playlists?

I NEED HELP!!!!
