I'm not trying to play the sounds simultaneously. I want to play them sequentially. According to the documentation on PlaySound the following code should return 'false' if a sound is currently being played but it should not stop the current sound.

   result = PlaySound(wavemem[waveIndex], NULL,
                          SND_ASYNC | SND_NOSTOP |
