lol, you mean none of you knew about this?
I noticed when I first played the PC version of AO way back in 2000. This bug also affects the PC version of AE too - I think it's a programming mistake with the game engine when they converted the game from the PSX version. But it's not really that much of a big deal 'cause it doesn't affect gameplay very much, if at all (it's rare that you hear stuff off-screen), so I never bothered mentioning it - Perhaps it's the same with everyone else who noticed it.
Swapping your speakers/headphones around is a way to solve the problem if you're REALLY that bothered by it, but then you'd have to put up with L/R Stereo sound reversal in the FMVs instead.
