    Video plays but no audio. Help!


      I have a 2011 MacBook Air with the proper configurations and Mountain Lion. I am trying to take an online course. The video plays but no audio.  I have tried all the suggested fixes, but nothing works.  Everything else works on my computer with no problem.  I need help fast.  Any ideas or known issues?
