Toshiba A135-4527 internal mic ?

[mikey99]

I purchased a Satellite A135-4527 , seems pretty nice
so far. I'm unable to determine if this system has an
internal microphone. There is a small hole on the front
of the laptop case, and the Quick Start card that came with the
system says internal microphone (available on some models).

At first I couldnt get the internal mic or the external attached mic
to work. After fiddling around with it for literally a couple hours
making sure no mic inputs in the Control Panel/Sound was muted
I installed the latest Realtek HD drivers. I could go through mic setup
wizard, and the volume indicator moved when I talked, but Sound Recorder
would not record my voice. SO I installed Power Mixer (shareware) and
all of sudden now I can record my voice in Sound Recorder and playback. I think this all points to problems with Windows Vista
and its sound drivers.
But I would still like to know if this has an internal mic, because even
with Power Mixer I cant get it to work.
