Marcelo, 

First let me say I appreciate your help. 

I do not want the program to require DirectX so that's out. I
want to be able to play sounds from memory. I don't want the program to wait for the sound to complete before continuing execution. The code which I have written works on most computers but not all. Do you have any suggestions. 

Chuck
