Try adding this line at the end of the file /etc/modprobe.d/alsa-base:

options snd-hda-intel model=XXX

Where XXX can be either:

vaio if you have a VAIO FE550G/SZ110
vaio-ar if you have a VAIO AR

To add this line, open the file with this command (from a terminal):

sudo gedit /etc/modprobe.d/alsa-base

Add the line, save and reboot.

Please make also sure that in Menu->System->Preferences->Sound you have selected the right mic under Sound capture (use the test button if not sure).

Since you have a VGN-SZ430n model, I think you should try with model=vaio.

It is not working. I followed the steps you provided. In the mixer I have two options (HDA Intel ALSA mixer and sigmaTel STACT 9872AK). I am using HDA Intel ALSA mixer. For sound Capture i am using ALSA - Advanced linux architecture

Try changing mixer to STAC and check all sliders/switches.
Is there no mic entry in Sound Capture!?

Nope :(

these are the things available i n Sound Preferences for capture device

Hey!! Updating the driver did the Trick!!... Thanks.. Now the Web cam.. If you dont mind can you please help me with that?

Good! Yes, for that we should open a new question.

So close this one and open a new one requesting help for you web camera. Please also include in your question the make of the camera and the output of an lsusb command (if it is an external camera) or of an lspci command if it is built-in.
If neither of the two list the camera try with lshw.
