The version of sox I have here claims to handle ulaw in wav just fine.

  $ file bar.wav
  bar.wav: RIFF (little-endian) data, WAVE audio, ITU G.711 mu-law, stereo 44100 Hz
  $ sox bar.wav -u baz.wav
  $ file baz.wav
  baz.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 8 bit, stereo 44100 Hz

Maybe you could email me a sample that I could play with, or at least
the output of `file foo.wav`.
