Select it by placing a tick in box
Slide its slider to about 3/4's up ... not all the way
In that advanced button option hides "boost" ... do use it , unless you need to
Close audio control panel by hitting the X box in upper right corner
Mic should be connected to PINK connector on audio socket on pc .
Should that fail , suspect bad mic .

Please refer to motherboard manual setup .
Some motherboards , if not all modern units , have a connector on the motherboard for connecting front audio panel connectors prebiult into case ... which can disable those actually fitted on the motherboard .
The motherboard manual will show how these must be set , in order to prevent issues .
