Uh, yes I do, and the cheats binded to numpad 1, 3, 5, etc do give the "On" sound, but the ones on 2,4,6, and 8 do not, these are binded to the in-game camera.
But not a single one of the codes work.
are you on a laptop/specialized keyboard by any chance?(if you are, you might want to relocate the buttons)
