Public bug reported:
When using the system testing tool I cannot hear anything recorded
through the built-in microphone.
When I turn up the sensitivity in the sound preferences to the max it
does seem to pick up sound, albeit with alot of amplified static.
The speakers are turned up and I other sounds play normally (e.g. the
logon sound). The microphone works OK in windows.

CheckboxData: The microphone does work. However, the microphone only picks up
anything if the "amplified" bar is set all the way to the right. When I do that
I get alot of hissing background noise. (Yes the speakers are turned up!). It
works fine in windows.
