make sure the wav is in 16-bit Uncompressed PCM format @ 22050Hz (I am not sure if Mono or Stereo is important, but this info comes from stock music WAVs which are Mono). If that is not your problem, then maybe the size is too big for the armada engine to handle, or maybe a spelling mistake or missing "_" with the singlePlayerMusic or multiPlayerMusic in your new race's odf?
That's about as far as my knowledge goes with audio files (I use NCH Switch and WavePad for audio conversion and editing, never had a problem with them).
