Itunes "Match" for allowing "protected ACC Audio files" to b e shared with Sonos
Using itunes library for Sonos we are unable to play music that is "protected ACC audio files". Sonos tech support recommends downloading itune "Match" for $25. Done. Now Sonos tech suggests deleting each protected song copy and then downloading (unprotected) ACC Aduio file of same song.
Sonos tech could not assist in the technique necessary. Any suggestions
