In case anyone was wondering, you can remove that horribly clipped sound when you open the menu in FC3. This was getting on my nerves and I'm really glad there's a way to take it out.
Basically you just need to open the DLL with a hex editor and search for sndMenuShow and sndMenuClose and zero them out. More details here , right after the requirements picture on the main post. Just replace the humming sound text with the one's I said.
I just did the mission where you get mushrooms for the doctor though, simple mission really but very well done. I'm really digging the soundtrack for this game.
