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.
