    Ok, so i am obviously new here, but let me assure you i have read through a lot of posts here in order to resolve my issue. So far no luck:

    I have an Imac running on OSX 10.6.8.

    THE PROBLEM: It will not locate internal speakers.

    It will play the startup chime but no other sounds. It plays through headphones and external speakers just fine. If i unplug the jack the volume control is greyed out and a crossed out circle appears and i cannot touch the volume slider. When i unplug the headphones a red light appears.

    SOFAR I HAVE TRIED:
    Rebooting in safe mode
    Rebooting holding down alt+command+P+R
    Uplugging the jack while rebooting
    Wiggling the jack
    Cleaning the jack and pulling it out several times
    Cleaning the socket
    Opening the activity monitor in order to quit the process that runs audio

    Nothing works. Any other suggestions are very much appreciated.
    Thanks in advance

    A fresh OS install may or may not work, but he could just as well try with the OS version he's running. Moving to a new OS Version before they're ready to isn't a good answer.

    You could try creating a separate account to try the sound first. If that doesn't work check with a fresh OS install - make sure you have good backups of your system.

    And if neither of those work, you may have a hardware issue.

    Sounds very possibly like the little switch in the jack socket that tells the mac that headphones are plugged in is slightly bent causing it to think that something is plugged in when it isn't.

    The solution if this is the problem is to take something thin and non metallic like a wooden toothpick and gently probe about in the socket until it sorts itself.

    This is often caused by using a slightly bent jack plug so check them before plugging back in.

    hope this helps

    On the Apple Support forums some folks have had success restoring sound by uninstalling iTunes and then re-installing it.

    Another poster had his "no sound" problem resolved here. Try the procedure with the supplemental update listed near the end of that thread.
