Chuck,

What leads you to believe that your target audio device can have more than
one MCI audio instance open at a time. Remember, DirectX's sound interface
is NOT like the MCI ( which is what PlaySound() uses ). You can only have
more than one audio instance open, IFF your device supports it ( many do
not ). If you need this sort of functionality, look around on the web, I
think there are a couple of ( at least semi ) freeware VCL's that will allow
you to open a DirectX sound device and play multiple streams.

Usually the first time I attempt to play the sounds I only hear the last
sound. On some computers there is a random delay between playing each sound.
Sometimes only the last sound plays.
