Check for any obvious damage to the adapter. If any of the outer rubber coating has been damaged so that the conductor inside is exposed, this could allow interference to enter the current and cause a buzzing sound. Untie any knots if the cord has become knotted. Make sure that the connection where the cord meets the actual box adapter is still intact; this sometimes can become damaged and make a poor connection.
