    Ok so, i have an Imac 2 ghz Intel core duo; 10.6.8

    I got it from my dad, already installed, and he didnt gave me the inst disk...

    the PROBLEM is NO SOUND.....

    when i go to pref>sound> there is no choise of internal speakers, and it doesn't recognize plugged in headphones or ext speakers.... pref>sound>output> the selected device has no output controls
    it shows only soundflower as option
    ive tried the jack thing, there is no red light coming from inside...

    ive resseted the PRAM, which gave me the start up chime..
    i tried a bunch of different things, i read about nothing helped..

    It looks like to me, it doesn have any drivers?

    How can I install drivers without installation cd

    Is there any way to bypass this situation, if its a case of missing drivers?

    PLEASE HELP, I DON'T KNOW WHAT TO DO????????

    You might give this a try

    I don't have access to a Snow Leopard (10.6.x) machine any longer, but back in the day, I would run across the same issue and discovered that opening GarageBand and playing any audio file (a sound loop, perhaps) would reset something, somewhere in the computer, and voila! I'm not even sure you had to play an audio file. Just opening GarageBand may have been enough. Good Luck.

    It looks like Soundflower has grabbed the audio and isn't configured correctly.

    You can go to "Audio MIDI Setup" in the Utilities folder (Applications > Utilities > Audio MIDI Setup) and select the built-in Output there.

    I'd also remove Soundflower, unless you are using a program or device that needs it.

    Are you saying there's no sound Preference Pane in Preferences? Or the Preference pane won't load?

    It sounds like there may be corruption of the audio kext in: System > Library > Extensions > AudioAuuC.kext

    Do you see the Audio kernel extension (kext) in that location?

    i correct myself.
    after rebooting, and another permission repair, it opened the sound pane, with again only two options soundflower 2 ch 16 ch...

    There is no option anywhere for built in, and also for option "output" the selected device has no output controls..

    ----------

    i see the kext file

    ----------

    im really desperate right now.. :confused:

    It looks like you may have a corrupt audio kernel extension. There should be a listing shown for the internal or digital output on that Preference Pane.

    The only other think I can think of is to take a headphone plug and push it into and out of the output jack a few times to be sure the contacts close all the way when there is no plug inserted.

    Some people have used a wooden toothpick to clean the contacts.

    On the Apple Support discussions, folks have reported success by uninstalling iTunes and then re-installing it.

    You can also try a SMC Reset: http://support.apple.com/kb/HT3964

    I would think it should be in the same location as the Audio.kext

    I edited my post with another solution to try first. If that doesn't work, a reinstall might be your only option.

    You could try downloading the supplemental update from apple here.

    Then read these posts, especially jonpaul's post near the bottom:

    Re: No sound on MacBook Pro after 10.6.8 upgrade
    Dec 27, 2011 9:58 PM (in response to nickmooney)

    Okay, I tried EVERYTHING.

    Trust Me.

    I even did the downgrading to the 10.6.7 HDA.

    HERE IS THE SOLUTION:

    YOU WILL NOT NEED TO LOOK ANYWHERE ELSE, IF YOU FOLLOW THESE STEPS:

    1. Download and install the 10.6.8 Supplemental Update from Apple (link below).

    http://support.apple.com/kb/DL1429

    2. Once the update is installed, and the system has restarted, type "Disk Utility" into Spotlight, press enter to launch it, and select your hard drive on the left. Then click "Repair Disk Permissions." (This step may or may not be necessary, but is a good idea in case there are discrepancies from the update).

    3. Once the utility is finished, plug in some headphones. Then, press the Option key and click on the speaker icon in the menu bar.

    4. Click the Headphones option under the "Output Device" section. You should get sound.

    Unplug the headphones and ensure that the audio is not muted. You should now also get sound through your speakers.
