Files Won't Play on SB2 But Play in VLC

I ripped to FLAC 'Shostakovich 24 Preludes and Fugues, Op 87' on Naxos 8.554745-46. When I try to play on my SB2, the screen goes dark and there is no sound. I have to delete the playlist then toggle power to get SB2 back to normal. There is no log entry to indicate a problem with files. The files play fine in VLC.
