Does the demo have the same problem? http://download.cnet.com/Halo-Combat-Evolved/3000-7441_4-10235611.html
It doesn't... but there are no intro movies that play either. In the program directory, there's only one *.bik file named demo.bik, which plays when you exit the game.
I even downloaded the bink player for Linux, launched the demo.bik file above, sound works... so then started the game at the same time and the works for both, at the same time.
There must be something about the transition from the intros to the full version game that breaks the sound (or something).
