Microphone problem

[zcrooked]

So yeah yesterday I tried to talk over mumble with a friend and he told me the mic was doing a strange noise so I've checked if my micro was muted/plugged anything like that but all my settings were fine until I see this shit.

here a picture.



I tried to listen to the sound my microphone to identify the sound it' s producing and it's like and "EEEEEEEEEEEEEEEEEEEEEEEEE" sounds, My computer is detecting my micro but doesn't let me talk thru it

This is kinda annoying if anyone know how I can do to fix it plsssssssss help
