Xbox app on PC party chart not working

That generic support doesn't really apply here. The problem is with a PC microphone, not an Xbox One microphone. The Xbox App on PC detects the mic and it works if I start a party via the app, but it doesn't work in any capacity on the Xbox One for parties
or game chat.

You can also check if Party chats work well on the Xbox app on PC (Windows 10/11) or on your phone.

I'm having the exact same issue. I have the logitech G930s too. While using the xbox app for just party use you won't be able to hear others and they can't hear you. The headset works correctly with game sounds while streaming to xbox one back to PC but
still won't work in the parties. The issue is that the headset will just not work at all with any type of xbox party function... While streaming xbox one to PC or while just using the party system in the xbox application for windows 10. (Microphone and earphones
will not work in party chat as said... while the ability to create, leave, and join the party actually work.)

Just so that I am clear when you are trying this in party chat? In game chat?

You can hear the other players in the chat but they can not hear you?

Are you starting the party through the stream on the xbox itself? Or are you starting the party through the xbox app on the pc itself?

These are two different things.

I personally have noticed that if I try and join a party through the Xbox itself and not the xbox app I can hear the other people but they can not hear me. If I join the party or start a party and have people join through the xbox app on the PC then it works
fine.

So try that and see if that fixes your problem.

The phone app works just fine with any account, but the PC app messaging works with another account but the party input is still messed up
