So basically I go to watch a youtube video and there is no sound so I turn it up to full still no sound then I try another video no sound.

Then I play on minecraft which had no sound as well then I decide to plug my skull candy in'kneds in still no sound?

In the sound preference pane?


Check Audio MIDI Setup in your Utilities folder.


See if smc and pram reset does anything.
