    After upgrading to 10.8 I can't get any sound neither from the mbp's speakers nor from the external speakers. Did anyone had this issue before ? I have attached a picture.

    Mac volume bar greyed out - no output

    Hey guys,

    I had no output from speakers, or headphones. And the System Preferences - Volume was greyed out.

    I tried everything up to and including a PRAM reset and nothing worked.

    Took it to the my company tech and after awhile he figured out what was wrong.

    The inner head phone jack was dirty. Head cleaned it with a qtip or a special computer cleaning device. Apparently there’s a internal sensor in the jack that will prevent the output from functioning if it’s to dirty. It’s not like a dropped the computer in a dirty pond. I would have never figured that out.

    Anyways, that’s what fixed it for me with the same symptoms as listed.

    :)
