I don't really know much about what I'm going on about here but I appear to have no audio during the pre-rendered film clip sections of the game. It seems fine in the game and in-engine cut scenes but in the pre-rendered film clips I have no sound at all.

Does anyone know anything about this?

EDIT: Never mind, I just had to tweak the settings some more and got it going.

Yeah, I've had the same problem too. I really don't know what's up with Soul Reaver on PC. For me I've switched to the emulated PS1 version, the PC version is so poorly done. :/

The problem is that newer operating systems have compatibility issues, when this game was launched it worked properly on PC's that used Windows 98. So i would suggest running a virtual machine running Windows 98.
