Thanks for attaching the alsa-info file, it seems that you're still using the out-dated 3.5 kernel, which has already reached its End-Of-Life [1].
Please install the newer hardware support to upgrade to 3.13 kernel or upgrade to 14.04 Trusty.

one question, are you using the pre-installed version of Ubuntu? (Your laptop comes with Ubuntu on it)

Anurag (anuragbansal89) said : #3

Yes I am using pre installed version 12.04 LTE .

I run the command to sudo apt-get update and upgrade.
Sound lost completely ... only working with headphone.
