Ubuntu Sound System Restart

I used to have some issues when I go to standby mode time to time and use continuously few days. Sometimes I my sound system is not working, I just here small annoying sound when I try to play a song. But following steps helped me to restart the sound program.

Go to : System -> Preferences -> Sounds -> Hardware

There you will see your device selected and down you will see a dropdown to select profile. In the profile list there is one option of "Off", select it and again select the previous value you had.... These steps fixed my issue .

I just wrote a quick blog post before I forget the steps !!!
