I'm using Ubuntu 16.04. From a few days back I can't hear the sound on my laptop. While checking sound settings It shows Dummy output on the section of Output tab. How do I resolve this issue?

enter image description here

  • do real shutdown (from windows if you have dual boot), post aplay -l result
