Microphone checkbox not showing in audio control

Ok, trying to get my mic to work. Have gone through the properties in the volume control for windows. No where in there, under any tab, is there a microphone checkbox. Have tried reinstalling sound drivers, different sound drivers, everything. Does anyone know a way for me to unmute my mic without that checkbox, because I have been told it comes muted by default.

Yes the mic is plugged in to the right spot, lol.

Thanks
