P.S. you don't happen to be on vista, are you?
eeh... actualy i am Are there issues with vista then?

I rewrote my sound module. Now, i give each soundbuffer a predefined ammount of sources, so i dont have to change the buffer for any source. The problem seems to be solved, but ATM i have many unused sources. Is that a problem?

You have experience with OpenAL. Can you explain me how your Sound-module deals with buffers/sources?

Thanx
