Hi jcl,
We do have many dll's that definately would affect DirectX, we have integrated SpeedTree and a lot stuff like that, but nothing that should directly affect DirectSound that I can think of.
It could be our dll's I guess, we have a few of those for sure. I might do some test with a simple program minus all the dll's if I have time. It could be the dll's causing the problem, but not going to get rid of all our dll's for our game to get 3DGS sound working, but if I have time will check if that is problem. That could be a possibility for sure I guess.
Thanks,
Loco
