It appears you have no sound or volume icon because your 'pulseaudio' process is missing (probably crashed).

Please have a look in /var/crash for any relevant files. If you find one upload it using this command:

  ubuntu-bug /var/crash/YOURFILE.crash

and tell us the ID of the new bug that creates.

I could not find any files in var/crash/ folder.

Still not able to hear the audio. Please find the attached file for your reference for debugging..

Thanks. That seems to say the same thing:

!!Sound Servers on this system

Pulseaudio:
      Installed - Yes (/usr/bin/pulseaudio)
      Running - No

I'm not familiar with pulseaudio on Ubuntu 14.04 but you may want to try starting it manually like in my 16.04 system:

  /usr/bin/pulseaudio --start --log-target=syslog

If that works and yours never really crashed then it sounds like a login session problem (failing to start the daemon) rather than a pulseaudio problem.
