Microphone muting in Vista

[Guest]

I seem to be having a problem muting my microphone. I have it plugged into
the normal mic jack, but when I open my volume mixer, where I expected the
microphone to show up, it was not there to allow me to mute it. I do not
want to have to unplug it every time since the jack is in the back of my unit.
