How does the microphone function work?

[D4rKv310c1ty]

Hey, as usual I was wondering about on some servers.

Andddd.

I wanted to know how to use the microphone functionality.
I mean like I have two, one that's in my webcam and seeds through the USB port

and the other than goes through the onboard sound on my motherboard.

So what do I need to do to be able to use my microphone on the client?

Detailed instructions please!
