Hello all of you,

I'm a new Delphi Programmer and I want to use Direct Sound 3 for Delphi

It's very simple: I just want to load a wave file in a buffer and play
Can you help me??????

When I will be able to do that, I will try to load 2 sounds in 2 buffer
and play them
in the same time...
It's a very simple question, but Help!!!!!!!
Thank you,
