IWHBYD Skull on HaloIII

Ok, I have every skull except for this skull. I have tried two different website’s combinations of rings, yet they do not work. I would appreciate any advice on this.

Follow everything listed on this site, and see if that helps any. That’s the guide I used.

Also, you know the rings are counted from the ‘safe’ end of the hallway to the scene where the Prophet is, right? (I don’t remember much, this was ages ago…)

Ya.

Well, I have only one problem. It says the hoops produce a musical note, and they dont for me. So when I finally do the combination, it doesnt work.

they flash not a musical note
