Xbox console companion game stream mic not working

I am having the exact same issue, my mic is being recognized but won't transmit sound. Out of curiosity do you have a kinect? Also my xbox is the original white xbox one. I can hear party voice and in game voice, but my mic picks up nothing. The companion
app prior to streaming picks up my mic when active. I've seen complaints going back 4+ years for this issue and I haven't seen a single working fix other that messing with what apps are allowed to use the mic, which I verified is set up correctly for me.

I'm sorry to hear you are having trouble getting it to work.. Have you tryed using a different Mic? Also sometimes in your settings your party Chat can be muted without you realizing it. Sounds like you could fix it using a different Mic than your Camera
Mic. Try Party chat, and using a Headset to see if it's a Hardware issue first.

I found a solution... wow this took a while, but after the amount of trouble I had I will be posting this in all the dead forum posts. Go into your ethernet or wifi properties on the computer you are streaming your xbox one to. Install the protocol "Reliable
Multicast Protocol". It should work after doing this.

Quando se abre a stream tem o ícone do microfone acima, já verificou se está tudo ok. Ou pode ser algo em seu Windows.

Olá, você está falando dos clipes de capturas de jogo, se for não é possível mesmo capturar o som do grupo, mas se caso for em fazer live tanto no mixer quanto na twitch é necessário ativar a opção e pedir que seus amigos no grupo incluam o áudio na stream.

Espero ter ajudado e aguardo sua resposta!!
