• Make sure the headset is not muted. To do this, check the mute button on the headset controls. (For a headset, the mute button is on the left side of the connector that is plugged into the expansion port of the controller. For a 3.5-mm chat headset, the
  mute button is a slider button on the front of the audio controls that are in the middle of the headset cable.)
