I want to start live streaming more and want a microphone but don’t know if I can use...

No, there is no Microphone you can use on the Xbox One. If you want to use it for broadcasting or Streaming, then you have to use a PC to stream, as that is the only way to use a microphone to stream or broadcast your games.

Hi,

the problem is that I stream and that if I touch dB via windows, I also change the volume of the microphone in live and that's what I want to avoid.

but, they don't work when you want to talk by chat or if you want to stream, if it's when you want to stream down the level from 10 to 20 and 100 to the microphone and the voice will be heard, if it's for normal chat update your control or verify that
the audio microphone is activated

I am using a capture card - external and a microphone on PC or laptop to stream or record .

this is the only option if you want your voice to be recorded .

Support no longer uses a direct number. You have to request a call back at http://support.xbox.com/contact-us However, it's an issue with the servers. A lot of people are having the same issue. All you can do is wait for it to be fixed.
