You can also just copy the files from the CD to the same "AUDIO" directory under "Pharaoh" There's no need to re-install the game. If the game sees the files there, it will use them. If not, then it won't.
It also depends on what kind of install you selected. I usually do a "Full" installation, but then go in and delete the files in the "Walker" directory, since I don't want to hear them, and I want to save the space.
