It's even simpler:
IDL> spawn, 'start myfile.wav'
You don't need to specify the player, Windows will launch whatever
application is associated with .WAV files. If the application is already
running it will just play the .WAV file without launching again.
I just tested the following and it works:
IDL> spawn, 'start message2.wav'

Have you tried SPAWNing your Audio Program with the name of
the WAV file to play? I think that's what I would do.
Cheers,
