I had that problem too. I have Soundblaster live 5.1 and the 5.1 surround speakers. I just turned the sound down untill I got through the area and never ran into it again. Even when I played through the game again it didn't happen. It must be just a bug that gets triggered somehow.
Your Schwarts is as big as mine!
I have fallen to the dark side and shall now be known as Darth Jaseen!
