Hi Pohkii! My name is Ricardo an independent advisor ready to help you with this situation!

In order for you to be able to chat in multiplayer, you must change the privacy settings of your account. It can be done here

https://account.xbox.com/settings

Child's account cant view their privacy settings an adult is required to add him to a Microsoft family here

https://account.microsoft.com/family/

After the adult account creates the family and adds the minor's account to his family

Have you run the steps in Update xbox wireless controller? All controllers you use need to run the firmware update.

The uSB method is my preference.

Unfortunately, none of these answers fixed this for me. Update though: looks like I can hear everything the other people in my Fortnite party is saying, they just can’t hear me. The weirder thing is, when I squad up with randos, the mic works just fine.
I can hear them and they can hear me. Again, same thing when I’m in an Xbox Live party. The only thing that doesnt work is my mic when I’m in a regular Fortnite party (not in an Xbox Live party).

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.

my mic doesn't work in game chat i try to talk to other players with mics and they can't hear me even though it shows my mic emitting noise next to my name. It works fine when im in parties though.
