I'm pretty sure I've read they're in sounds.dat in a RAW PCM format.
Edit:
Yes, 16 bit RAW PCM in 8192 Hz. Open with Audacity or similar as "Import Raw" and enter these settings.
Edit 2:
Also, the music is just MIDI files with sounds from the sounds.dat file as the soundfont.
Edit 3:
There are some unused sounds, like a Slig saying "Stay!"

THANKS!!!
