I don't have any sound issues during the movies, nor do I have any problems in the intro movie. Not even using a soundcard, just an AC97 on-board soundchip. Machine is a P4 3.0Ghz HT with 1 GB RAM and a x700pro with 256 MB video RAM. I actually don't have any technical issues with the game at all (been playing for about 16 hours now, both on- and offline). No crashes, no slowdowns, no skips .. to me it looks like a polished game, but yes, I see the posts from frustrated players too, so I guess I'm just lucky.
