No movie or music sound/audio

[dogmut2000]

I get no sound from the movies and no music during gameplay/main menu. I hear other sound effects like footsteps, birds chirping, menu selections etc. I can play and hear the audio in both the .bik and .ogg files run outside of the game.

I've re-installed, run pre and post patch, played with the hardware acceleration slider, installed codes (I don't have any codec packs installed).

Any ideas? Does the game not use the system codecs?

Thanks,
dogmut
