I have heard dripping sounds due to an old flapper or the flapper valve seat. Check to ensure the seat is smooth and free of buildup or deposits. If it is rough or has channels worn in it a replacement is in order as the flapper will not seal and this a drip will be experienced. If it is left for a while the tank should refill periodically by itself as the water level decreases.
