Xbox Game Bar detects my mic but my mic doesn't work in Party Chat

If I go in the Xbox game bar the microphone settings detect my mic and the bar goes up but when I'm in a game or party nobody can hear me

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.

Thats what I'm doing.. the only thing I am doing different from playing keyboard/mouse is the controller itself. but when i plug it in every setting on the pc changes to controller mic. Even though the controller has no mic. So I go back through all the
pc settings and xbox companion settings and change it back but the xbox game bar will not let me use the usb mic anymore. I have to unplug the controller and reset the pc to be able to use my mic again. when I start a party in the companion app it says my
mic is working , but if i am in a party on that app for some reason I'm not in a party on the game bar... so if i start a party on the game bar the mic still doesn't work..

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.

I am having the same issue. With my headset I can hear game audio, if I'm in a party chat I can hear my friends talking but the mic doesn't work. My mic does work outside of the xbox app perfectly. The headphones and mic are set to default in the playback
devices. It's an issue with the app and it needs to be updated.
