Samsung NC10 built-in microphone too low to pick up any sound

[StuJordan]

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.

Running Karmic 2.6.31-12-generic #45 (Tue oct 13). On Samsung NC10

* Sound preferences->Input-> Internal Analog Strereo - unmute and increase input volume.

Sound output set to 50% I was able to clearly hear the voice I recorded.

Marking this bug as fix released.
