xxxIndyxxx: Does that also include the ingame music (which doesn't play in this version of AVP classic)
Tolya: We have added the soundtrack, please redownload/sync the game to get the update ;)
Sorry for reviving this ancient post, but I went looking for the OST on my AVP GOG purchase after reading this and only found the native .bik files used by the game in ...\GOG Games\AvP Classic\FMVs.
This post had led me to believe that GOG was offering a rip of the original disc that accompanied the original release.
That does not seem to be the case, so I'm guessing that previous GOG versions of the game had no music, just SFX.
Anyway, if anyone stumbles here and also wants to listen to the soundtrack outside of the game, you can download the official RAD Video Tools for free (non-commercial use) here:
http://www.radgametools.com/bnkdown.htm These tools allow you to play the .bik and .smk files found in the game's directory.
The tools also allow you to convert these files to .wav so you don't have to leave a piece of software installed just to listen to a specific OST.
