I just got this and installed it tonight. I have sound effects but I haven't noticed any music and no audible dialog during the opening except for Alan's kid screaming when the laser hits him. I've patched it and reinstalled the game.
any ideas?

What's your pc setup like? My sound works fine (sb live), win xp

sorry, forgot that info
P3 500mhz
256mb ram
geforce 2 Ti 64mb agp
sblive value
win98se
game runs perfect except no music (not sure when there should be music) and there was no voices during the opening and I assume there should have been, and no voices in the game when talking to people if there is supposed to be voices at that part

I don't hve anything to add, but I will say that you are in for a treat if you can get this game working properly. I found this game surprisingly fun and enjoyable the whole way through.

it's been fun so far, only played for about an hour. with the subtitles on the sound issue is only an annoyance, kind of big annoyance, but won't keep me from playing
when I get home I might look into driver updates for the sblive since I think I might be using the original shipped drivers

well, while waiting for the sblive driver to download (I'm on dialup) I looked around tron20.com and found the answer. I have to delete 2 files from the windows\system folder and reinstall them
