Xbox App - Party Chat doesn't see my Mic

At the moment, I am using a usb headset through pc. Party chats on the app work, and parties on xbox I see, through the stream, register my mic. But it doesn't transmit my voice. Which is why I'm extra confused.

hey how did you use your mic in xbox app party chat in the first place? i launched "start a party (beta)" and it shows my mic, but i can't talk or hear anyone in the party chat. and my mic is the default recording device

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.

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.

Hey. So I'm currently on Windows 10 using the Xbox Companion App, and I'm trying to join my friend's party chat (who is on Xbox One). However, when I join the party (or they join my party), I can't hear them and they can't hear me. When I speak
into my microphone, I can see the party chat flare light up, so the Xbox app is picking up my mic (but I can't see their flare when they speak). I'm using a split 3.5mm jack with an Astro A10 headset. My mic works fine on Discord and other services, but for
some reason the Xbox Companion app isn't working. I've tried changing the audio settings both on the Xbox app and Windows to other devices, made sure my privacy settings allowed my mic to be used on the Xbox app, hard resetting the Xbox app, restarting my
PC, plugging my headset/mic out and back in, messed around with my mic settings on Windows and the Game Bar. For some reason, my microphone, specifically in an Xbox One party chat using the Xbox Companion app, doesn't seem to work. Both the Xbox app and Windows
is up to date. Like I said before, the party chat is picking up my mic evidenced by the flare when I speak, but my friends can't hear me and I can't hear them. I've looked up and tried almost every troubleshoot option online and nothing is working, and it's
driving me mad. It used to work on my old PC, and I just got a brand new PC yesterday as of posting this and now the problem occurs. Anyone else having this issue? Anybody know how to fix it? Please help!
