Okay...we have such a function in our project :)

Good to know :)

Well, I use SDL_MixAudio to mix the sounds.

The code I use can be found on
(Comments are written in German)

A short description:
We have arrays to store the name of the soundfile (just to know what

Then I prepare the spec structure with needed data, load the WAV, store
the callback function and opens audio.

That's all but no sound :(
