This is kinda off topic for this forum so don't be surprised if this thread gets closed. While you're at it, take a look at a
previous thread about this and try my suggestions there. Now, you could have located this thread by using the search button, I guess it's hard to see that button on this page, but why didn't you even read the game's readme ? Open the readme.rtf (I like to imagine rtf stands for Read The F*cking, heheh) and search for "Missing Game Sounds", it explains about everything you need to know.
