how do i check to see why the mic is not working
1 Check that your microphone is connected to the correct (normally pink) socket in your computer.If itâs a mic with a USB connector just make sure it is properly connected to the USB socket (you will not use the pink microphone socket in this case).
Check that your microphone isn't on mute. Some microphones have buttons to mute or un-mute. If you're using a headset, it may have a mute switch on the side of the headset or on the cable that connects to your computer. Close any open applications that use a camera or microphone.
