Headset mute button lit - controller update fixes it, but it fails every re-start

Hey Halo Brigadier! Can you tell me which wireless headset you own? Have you tried re-syncing your headset, or changing the sync position?



To sync, press and hold the sync button on the console (on the original console, the small circle button near the power button; on the S console, the small square button by the front USB ports) until the lights on the console power button start to spin.
Then press and hold the sync button on the wireless headset, located on the microphone. The lights should also start flashing on the headset.



Once they sync up, only one light will remain lit up on the headset, either 1, 2, 3, or 4. This indicates what player position the headset is synced to. For instance, if you are holding the first player controller (indicated by the upper-left light on the
controller) then you want your headset to have the 1 light lit up.



If the wrong number is lit up, tap the sync button on the headset until the proper number is lit up. If it seems to skip the number you want, you may have to turn all your controllers and wireless headsets off, and resync the headsets first, then the controllers.

Let us know how this works out for you!

• Disconnect the headset or unplug the headset cable from the bottom of the controller, and then reconnect it firmly to the controller (in the expansion port for a headset or the 3.5-mm port for a 3.5-mm chat headset).

• 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.)

My mic mute button was lit up and didnt work. So I updated it and now the mute button flashs and still doesnt work. What does that mean?

• Disconnect the headset or unplug the headset cable from the bottom of the controller, and then reconnect it firmly.
  

• Check the mute button on the headset controls to make sure the headset isn’t muted. An illustration shows an arrow and a finger pointing to the mute button on the headset controls. An illustration shows an arrow and a finger pointing to the slider mute

• Increase the audio. If you're using a headset plugged into the 3.5mm port, go to System > Settings > Kinect & devices > Devices & accessories, and then select your controller to adjust your audio options.

• Try using a different controller or headset to check for a hardware malfunction. Update your controller to make sure you have the latest software.
  

Greetings.

As mentioned below, check for controller updates. If this option does not work, then check to make sure the mute button is off or the your settings in the Xbox itself. Believe it or not, self muting happens alot

If all else fails, try borrowing another controller and see if you have the same issue. If still the same, I would check the headset compatibility with the xbox controller and/or contact support
