Twisted Metal : Head On

[Niobium]

Yes, I know about this trick and try it - no effect.
So, this problem not fixing by this way...
Unique of this sound problem that the only SOME of SFX do not playing. Sound at the menu (when player choose something or move cursor - sounds correct), during the game sound of some weapon are playing, but not other, ambient on a half of the stages are playing e.t.c. Approximately - 80% of SFX do not "show", however other 20% works no problem. Strange...
But this is not big problem - I have completed this game 5 times with different characters without problem...
