I have a USB drive with all my music plugged into my “always on” PC and set up my music library to point to this D drive. It worked for months, but now continually gets Unable To Play ‘xxxx’. The Share //DONSNUC/D does not exist. Same whether I play from the Sonos S1 app on the PC or on the phone or iPad. If I go to Windows Exporer and click the D drive, then albums and click on something, it plays just fine via the Windows media player. This is only a Music Library issue. If I choose a TuneIn radio station, it’s OK. What to do?
TIA Don
