Brian,

This sounds similar to a problem I've had when converting MP3 files to
WAV format for burning audio CDs.  The problem was solved when I
turned on the byte-swapping option in my Linux CD-ROM burner app
(xcdroast.)  Since the audio is in 16-bit chunks, problems can occur
when the byte-ordering is not correct for your machine.

Check and see if 'read_dat' has an option to perform byte-swapping on
the actual audio data.  If not, check out the source code for cdrecord.

Hope this helps,
