If other players are unable to hear you in Xbox Live chat on your Xbox One Console, please check the following:
1. The Mic Boom is Plugged Fully into the Mic Boom Jack
First, make sure the mic boom is plugged fully into the Mic Boom Jack. Disconnect the mic boom by pulling it straight out and plug it back in, making sure to plug it in until you hear a "click". This may take a couple of tries.
2. The Headset's Mic Boom Is Working
After checking the Mic Boom, test the headset by plugging it into a mobile phone and making a call. If someone is able to hear you in the call, then the microphone itself is working properly. If someone was not able to hear you, then there may be an issue with the mic boom. If that is the case, please contact our Support Team: Contact Support
3. The Xbox One Console and Xbox One Controller are Functioning Properly
Occasionally, you may lose chat due to a console or network error. To quickly resolve this, try power cycling the Xbox One. To power cycle the console, please do the following:
1. Disconnect the HAC from the Xbox One Controller.
2. Shut down the Xbox One console and disconnect the Xbox One power cable. Leave the console unplugged for a minute.
3. Plug the Xbox One power cable back in and power on the console.
4. After the console has completed start-up, log into your Xbox Live account.
NOTE: If Instant Sign-In is enabled on your Xbox One, log out of your Xbox Live account and then log back in.
5. Plug the HAC back into the Xbox One Controller.
Any errors with the Xbox One console should no longer be present. The microphone should now be functioning properly.
4. Xbox Live Gold Membership is Active and Privacy Settings Are Configured
Make sure your Xbox One is enabled for online chat. To quickly determine if the issue is with the settings and not the HAC, try using the standard Xbox One headset that was included with the console for chat. If you cannot hear chat when using that headset either, the issue may be with the settings or your membership. Make sure your Xbox Live Gold Membership is active and configure the privacy settings:
1. Sign in using one of the following accounts:
a) Your Xbox Live account
b) The parent account of the child account
2. On the controller, press the Menu button.
3. Select Settings, and then select Privacy & online safety.
4. Select the privacy setting you have enabled (child, teen, adult, custom).
5. Select Communicate with voice and text.
6. Choose specific friends or everybody.
If other players still cannot hear you in Xbox Live chat, then there may be an issue with the Headset Audio Controller. Please contact our Support Team for further assistance: Contact Support.
