Brauche Hilfe bei playSound3D

function toggleVehicleEngine ( player, key, state )
	local veh = getPedOccupiedVehicle ( player )
	if getElementModel ( veh ) ~= 438 then
		if ( getPedOccupiedVehicleSeat ( player ) == 0 ) then

			-- Falls das Fahrzeug neu gespawnt ist und noch keinen Benzinwert hat
			if not getElementData ( veh, "fuelstate" ) then
				SetElementData ( veh, "fuelstate", 100 )
				SetElementData ( veh, "engine", false )
				setVehicleOverrideLights ( veh, 1 )
				SetElementData ( veh, "light", false)
				setVehicleEngineState ( veh, false )
			end

			-- Falls der Motor läuft -> immer abschalten
			if getVehicleEngineState ( veh ) then

				setSoundVolume(sound, 0.2)

				local sound = playSound3D("sounds/EngineStop.mp3", 0, 0, 0, false)
				setSoundVolume(sound, 0.2)
				attachElements(sound, veh)

				if tonumber ( GetElementData ( veh, "fuelstate" ) ) >= 1 then
