This may be a daft question but after sharing my music fold, via computer/ external hard drive, with the sonos app do I still need to keep the hard drive connected to the computer and switched on when I want to play music from my folder. I know that I could just disconnect it to see what happens but it has taken me days and hours to figure out how to do and for it to work. My music includes all my vinyl that I transfered on to mini discs and more recently had digitalised which sounds great when played on my 2 sonos one's as stereo.
