On a test box, say the RasPi Rivendell (corrected) you mention below, run rdadmin. click manage hosts. highlight the host in question and click edit. click rdlibrary. about halfway down change Format: from PCM16 to MPEG Layer 2. save everything until you are out of rdadmin start rdlibrary and import a new song into a new cart. try to play the cart. if it plays... from a terminal: file /var/snd/999999_001.wav where the filename bit corresponds to the cart/cut you just imported and played.
