The microphone mute button is not working on my T400s running Windows 7 RTM. The speaker mute button works (when I press it the light comes on and sounds goes off).

When I click on the microphone button the light doesn't come on and the microphones don't mute. Is there a drive I am missing or something? I can't find a drive for the button on Lenovo site.

Anyone out there have this button working?
