I know it's quite a neglectable thing, but on several systems I tested the game with, the sound in the first short videos was quite messy. Did you "suffer" the same issue and does it show on later videos and cutscenes too?

I don't have the game on GOG, so can't answer you explicitly, but I used to have a similar problem with my own version: the bink cinematics would start out fine, but the sound would get progressively more stuttery, until it stopped completely on longer cutscenes. I never could figure out the cause of the problem, or a reliable fix. I've wizened up a bit about these things, so I could take another whack at it, but for now I can't help, sorry :(

So far I've only encountered that in the initial logo videos. I have yet to experience it during any other. *shrug*

Same here, so it's a non-issue for me.

Me too, it's only in the logos screen apparently.
