Just a minor (if irrelevant) correction...  What's on normal audio CDs
are not WAV files.  It's raw headerless PCM, and contiguous from
beginning to end.  There is a TOC section in the beginning that describes
the starting locations of each track, and other info.  "WAV" connotes
Microsoft RIFF headers, which do not exist on an audio CD.

I know, picky, picky. :)

Try playing some non-CDR (i.e., factory pressed) discs.  If they work fine,
then your hypothesis is probably correct.  Otherwise, your changer has
probably gone south.
