In the original versions of the game, ID used a different file naming scheme for its soundsets than either of the BG games. I was sure I had downloaded someone else's conversion of the sets for the NPCs from one or both of the BG games to use in ID, but I cannot seem to find it anymore. Other than manually doing it again myself, has anyone else managed to do this with the EE versions of these games?

I think that this is what you're looking for.
