The sound of the timed levers in Labyrinth

Hi Exiles,

i am looking for the sound of the lever pulled in the Labyrinth to bypass some of the fire traps, where you have to pull 3 or 4 levers within a short time to open the shortcut door.

Background: I am creating a similar puzzle in a non commercial exit room for friends and i would like to implement those sounds as a signal for the player, that there is a machine running in the background and time is of the essence when the first button is pressed. Unfortuantely, i can't find the sound anywhere. I have installed VisualGGPK to look for it (sorry GGG, no harm intended :)) but i can only find dialogue files, nothing as gritty as door opens or the levers. I might have to play the game and capture the sound somehow, but not too experienced with this :)

perhaps look into finding the source files embedded somewhere
