Can't hear or talk in game chat

Hello there this issue is happening to a few people tonight but this problem should be fixed for the morning

Hello there sorry to hear that you’re still having this Issue please follow these steps

sorry for the inconvenience

• Disconnect the headset or unplug the headset cable from the controller, and then reconnect it firmly to the controller
• Check that the headset is not muted by checking the mute button on the headset controls
• Increase the audio by going to Settings>Device & Accessories and select your controller to adjust audio settings
• Use a different controller or headset to check for any malfunction on the hardware
• Update your controller to get the latest software
• Ensure you’re using the Xbox One headset with Xbox One controller only as it isn’t intended for use with other devices, plus the console doesn’t transmit game sounds or music through the headset
• Clean your Xbox hardware by checking the headset, cord and connector for any defects. Ensure there’s no dirt/debris on the headset connector.
• Check the controller’s batteries, if they’re low, they won’t provide power to the headset, so you need to charge it before using it.
• Reboot your console by unplugging the power cord for 15 seconds.

Its been a day, still nothing.

Also can hear but can't talk to people in game and party chat. Is this related?

My headset only works in party chat. When I'm playing other games I can see that people are talking but I can't hear them and they can't hear me. It only works in party chat.
