My headphones stopped working on my macbook air My headphones on my Macbook Air just stopped working! Like they are "stuck on mute". I take them out, no red light on the jack, and they work perfectly. But once I plug my Headphones in, the volume just stopped! I have tried messing around in preferences, nothing! I can't seem to find any solution for my problem. People have the jack red light problem, but I can't get my volume to work! In fact, just now while I'm writing this my volume isn't working! I can't seem to find anything to help me with this. Nor have I found anybody with the kind of problem I have. I would greatly appreciate your help anybody. But this has happened before, and simply restarting my computer worked. This time, nope. Zilch, Zero, No help at all.
Please try this command as admin in Terminal:

sudo killall coreaudiod


It will solve the problem without rebooting
