Q: Sierra upgrade - NO speaker sound

After upgrading my MacBook Pro [13'3 inch, Mid 2012] from El Capitan to Sierra my internal speakers stoped working and headphones as well. The only way I can use the sound is through Apple TV.....

Reinstalled Sierra, ran Utility disk, checked sound settings, restarted the computer several times but nothing have solved the problem. Please help!!!

MacBook Pro, OSX 10.12
