After running the fixit, built-in microphone has started working. I tested by using the Echo sound test on Skype and it is responding quite well now. The problem now is, it does not respond while my headset is on. I am unable to hear from the headset nor my voice is going through the microphone.
I don't know if the setting for using the headset is different.
Many thanks for the FIXIT information, atleast I am able to use Skype now.
Waiting for your reply.
