I don't know if it will work for you guys or if I put this in the right spot.
1) If you're using DOSBox right click on WOLF and open "Start Setup"
If NOT using DOSBox find the WOLF files and open Setup file
2) Select "Sound Source"
3) Scroll up until you find "PC Speaker"
4) Press save
5) Run WOLF
You SHOULD have sound, I did. If that doesn't work for you I'm sorry. No idea how to stop the music from getting messed up so I just turned my music off, if you know how to prevent that tell me please.
