It turns out that mplayer itself can do the conversion.  The .wav file
sounds fine played back from the hard disk, but I have problems
burning to a CD.  The burn seems to be fine.  The CD is detected as an
audio CD and the track starts playing, but all I hear is beeps and
bleeps.  I tried both normal and byte-swapped burns using xcdroast.

Here's what mplayer reports on playback:

  Playing cd-rw/foo.wav.
  Audio file detected.

Any suggestions?  Thanks.
