Check the overflow pipe in the cistern tank as some fill valves do not stop completely but allow input of water after the noise has stopped. This allows the water level to rise up and the water to flow out into the toilet bowl. Reduce the water level height by adjusting the cut off level and when the water rises past the new level the increase pressure on the valve will shut it off.
