Maybe something wrong in your code? I can play here all sorts of wavs and mp3s without any problem...
Try this:
With the wav on the same path as this program. If that doesnt work, then I dont know :P
Try this:
mySound=LoadSound("sound.wav") SoundVolume mySound, 0.5 myChannel=PlaySound(mySound)
With the wav on the same path as this program. If that doesnt work, then I dont know :P
