[all variants] Internal Microphone not working

view story

http://ubuntuforums.org – Besides the problem in this thread, I have one other. The integrated microphone on my netbook doesn't work. At least, it doesn't work on most things. I can listen to it on the speakers/headphone by playing it in VLC through 'devices: audio capture: ~' And in Audacity, if I select the devise in the recording mediums it works, but having 'default' selected doesn't work. The microphone doesn't work in web browsers, or in Skype. And in the sound preferences menu in Linux, the 'input level' indicator does nothing. These things all work if I have an external microphone, but not with (Hardware)
