Hey painkiller, I did some tests. I also didn't get any sounds with your script at far distance. The only thing I can think of now is indeed that the force function is the problem, but only the function(s) it seems. Cause e.g. if I move rigid objects (with an attached sound loop) with my character controller they continue to make sounds. So my quess is that its a bug with the physx force function.

-edit: a possible solution might be either just a dummy entity that you move normally with the player and play the sounds on it, or use snd_play and based on distance to camera calculate the right volume.

Merry Christmas
