Manfred Hampl (m-hampl) said : #2

I suggest that you try the following:

open a terminal window and issue the commands

sudo modprobe -v snd_hda_intel
cat /proc/asound/cards

What output do you receive?
Does sound start working?

Really thanks for your help buddy. But I was in a hurry so I reinstalled my Ubuntu , Problem got fixed. It was occurring becoz I tried to install the realtek HD audio driver but instead of using the alsa driver it overwrite it and failed to install so there was no audio driver installed...

The Problem got fixed with clean install.
