SPOILERS necessary for me to explain this glitch...
Anyway, when I'm on the moon, and after you-know-who has been deemed dead, there's a scene where you run back in across that super-long bridge toward the radio transmitter. Once inside that zone, a cutscene plays where Jade gets an email telling her that he's actually alive. Then she runs back onto the bridge and they have a touching reunion, etc etc. Then, while he's explaining how he survived, there's a short bit where it goes into 'flashback' mode, and a clip of her crying or whatever and holding his hand plays. However, my sound cuts out here. For the rest of this cutscene, while double-H and Peyj talk to her, I've got no sound. Worst of all, I've never played this game before, and this cutscene seems plot-important, and now I can't hear it! Has anyone else had cutscenes lose all their sound? I tried opening this scene-- I'd saved just before it-- three times, even rebooting the game in between, and no dice. Sound's missing every time.

Maybe try lower hardware accelaration for sound in windows settings.

I tried the hardware acceleration thing and it didn't help; then I switched things back to normal and just kept restarting the game over and over until it finally worked. I don't know what the deal was with that; it was a pretty weird bug. But at least I got to see the end of the game!
