Here's the tutorial in order to get the microphone module working on VAIO VGN-SR46GD laptop.
OS: Linux Mint - Gnome
Important: You need to install build-essential package before beginning this process;
sudo apt-get install build-essential
Download the source file from the web site: Realtek Web site
select the appropriate device (High Definition or AC'97) - for this laptop the device is High Definition
Unzip source code:
tar xfvj alsa-driver-1.0.xx.tar.bz2
Compile and install source code:
sudo make install
After reboot you should have the microphone working, go to sound properties, Input and un-mute it...
Update: Sometimes after installation you might lose all configuration of ALSA, thus losing all input and output devices (happened for me several times), if so use the following instructions to re-configure ALSA. Then you'll have both input and output devices working.
Basically, you need to update Alsa, so:
First add PPA:<meta content="text/html; charset=utf-8" http-equiv="content-type" />
sudo add-apt-repository ppa:ubuntu-audio-dev/ppa
Then, apt-get update:<meta content="text/html; charset=utf-8" http-equiv="content-type" />
sudo apt-get update
Then, Install:<meta content="text/html; charset=utf-8" http-equiv="content-type" />
sudo apt-get install linux-alsa-driver-modules-$(uname -r)
Then, Reboot. Now you should be Done.

That's it, Cheers...
