I can’t get game chat to work on Xbox SX. Party chat works fine but I can’t hear anyone or...

Check out this page which has some troubleshooting steps: https://support.xbox.com/en-US/xbox-one/console/troubleshoot-sound

They have a specific section for game or app audio being inaudible during party chat with details on checking the Chat Mixer settings.

Did you ever find a solution? Mine does the same thing and I have an XBox One brand level 3 headset. Works fine on party chat, can hear people in game chat, they can’t hear me. I have voice overlay on and my name doesn’t even come up as if I am talking.
Checked all privacy settings, reset xbox, controller and console updated, etc..

Test in groups of other games then. If the error is only in 1 game, possibly the game chat option is disabled for that game.

Hello!

My name is Dérek, I'm an independent platform consultant and I'm grateful for the opportunity to help you.

Cooper, this game chat error, the only configuration it has would be the one below, friend.

Please try again

https://account.xbox.com/en-us/Settings?rtc=1&a...

Let's set up your account then

Go to the top right corner, click on your avatar

click on xbox profile(warns me if it doesn't show up)

will open a green screen

click on privacy

will open another screen, with your gamertag and big photo in the center of it

below, it has 3 tabs, privacy, online security windows and xbox

in these 2 tabs, allow everything, and at the end of each one, click "send"

I remain at your disposal if you have any further questions.

Thank you but it is still not working
