My Sonos is reading My Music Library from my WD MyCloud NAS just fine. I have a 'Top Rated' playlist created in iTunes. iTunes itself even reads it from the NAS as opposed to direct from the library on my iMac. I've exported it as an m3u file and imported it into Sonos. Sonos even lists all the tracks. BUT, when I try to play it, Sonos cycles through only finding 1 track to play. I can't export the Playlist within iTunes when the MyCloud is selected as the source; it's greyed out. I can only export the playlist from iTunes when 'This Computer' is selected. Any advice would be appreciated.
