Can't open iTunes files

SORRY – this post belongs in the server forum but I don't see how to move it or delete it. I've reposted it there.

Just recently I started not being able to play my iTunes files. I get "Can't open file: <filename>". I have this problem using Squeezebox hardware (Boom and Duets) and Squeezeplay. I found out that if I use Squeezepad, it works fine. I've done a clean install with no change. Running the server on another Mac works fine. I've been running it on this Mac for over a year with no problem. Looking at the transcoder log, it appears that the hardware uses the faad command but Squeezepad uses something else. I'm not sure what this means.
