How to turn off internal microphone

[scissorband]

I took a screenshot of the settings and as you can see it's picking up sound from my TV, talking on the phone, noises from outside, etc. even though I put everything on the lowest settings.

Some solutions say to pick a different device but it only shows one for me.

How can I turn it off completely?

Can I ask how it's affecting you if you don't want to use it?

Apart from physically unplugging it from your logicboard? You can't.

Why does it matter anyway?

Is it difficult to disconnect it from the board? I mean, I've replaced the RAM/hard drive before but apart from that I don't know how to go much further.

Dude didn't you know. The government is spying on us through our computers!!

How do you know it isn't already turned off when not in use?

To turn-off the MacBook Pro's internal mic.

Hi!
I've got a later 2009 17" MacBook Pro (using Leopard) and the way to shut-off the mic is this :
open the Applications folder and open Utilities, click on Audio-Midi and click in the 3 MUTE boxes.
That's it! (I guess Apple should've put these controls rather in the System Preferences dept.)
