Sound Goofs on Patched Games..

[Alien Pigeon]

Hello,
Im' new to this stuff, but i keep running into a problem. I have a PAL version of Resident Evil Survivor. I patched it, I did all the stuff to make it work, and It does. Works awesome.. But there is a strange sound problem. during real time cut scenes, or times where there is speech, the dialog gets cut off. sentences or statements never complete. yet during the game, sound fx, music, everything else seems to play fine.

What am i doing wrong?

thanks
