Microphone still not working while streaming.

The Xbox One does not support USB Microphones. You could just use a headset for talking while streaming your games or stream using your PC, and use a USB microphone on there instead.

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.)

is his microphone and everything works fine in his computer before stream?

Hello @ItsBelkon!

Currently the Xbox One does not support USB Microphones. You could just use a headset for talking while streaming your games or stream using your PC, and use a USB microphone on there instead.

As there is a standard for webcams introduced in Windows 10, most "off the shelf" cameras that are certified for Windows 10 will work with Xbox One as a replacement for the camera part of Kinect for streaming.

However, for USB microphones, there is no such standard yet, and therefore, Microsoft can't add multiple different drivers for USB microphones, as it makes no sense to add a driver for multiple types of Microphones.

So either get a microphone that has a 3.5mm jack and put that into the controller (with an adapter to convert the Microphone jack to a CTIA compliant jack if necessary), or set up your stream to go through your PC and use the Microphone on your PC to add
your voice to the stream.
