GM:PlayerFoostep is broken

[Zenolisk]

It seems that GM:PlayerFootstep only gets called when the Player is fast enough, is there any way to fix this?
Here is the code im using client and server side

function GM:PlayerFootstep(ply, pos, foot, sound, vol, filter)
    return true
end

[Rubat]

The GM:* hook is only called after every single instance of hook.Add PlayerFootstep is called, and all of them returned nothing. That means that GM:PlayerFootstep may not be called for you AT ALL in certain cases.
