Xbox party and game chat.

Join an Xbox party chat, go to options and switch to game chat. You can then leave the Xbox party and the fortnite party chat should work again

hi,

what sometimes can fix it is if you start an xbox party then go on to fortnite and then go on to your friends list then tap Y to go on to audio settings and turn voice channel on to game or party chat not xbox party chat then click on xbox party chat game
chat again and it should be fixed

You may have been in game chat while you where in an Xbox Live Party. Check the features in your party settings to make sure you are in Xbox Live Party chat and not in game chat.

Hi AustinM2,

Thank you for posting on the Xbox forums. I'd be happy to help.

Are you streaming to Twitch directly from the Twitch app on the Xbox? Or are you streaming your Xbox One to your PC through the Xbox Console Companion app? Are you using party chat on the Xbox, or a party through the Xbox Companion app?

What you are describing is by design using the Xbox Live party chats because the servers for the chat are separate from the in-game chat servers. Xbox Live parties effectively mute in-game chat, and mute yourself from in-game chat as well because as I mentioned
previously, party chats and in-game chats run on different servers. Xbox Live parties are more private channels for chatting with friends, so the muting aspect is by design. I believe this is why many Twitch streamers use Discord since you can hear both the
Discord chat and in-game chat at the same time.

are you doing Xbox chat or game chat? If you are doing game chat there are issues with fortnite atm dealing with game chat but you can try to turn off and on party chat settings and make sure that within the game that you want to be in-game chat or party
chat within the lobby.
