    Resetting PRAM didn't help me either ....

     

    I have also tried the following suggested in this article

    http://applehelpwriter.wordpress.com/tag/grayed-out/

     

    Any other suggestions?

    This solved my problem. The volume icon on the top bar immediately returned to black, and I have volume control back.

    I have the same problem but it came and time after time, I lose sound control after every reboot and I found this unique solution to do the trick :http://applehelpwriter.com/tag/grayed-out/

     

    The first manipulation did it as any other did not, I am looking for a definitive fix now.

    Finally, I fixed it and so far so good.

     

    What I did is:

     

    Open a console and type in :

     

    sudo chown -R _coreaudiod:admin /Library/Preferences/Audio

     

    This will fix permissions.

     

    Then type in:

     

    sudo update_dyld_shared_cache -force

     

    This will clear and rebuild dyld (dynamic linker)

     

    And finish with:

     

    sudo killall coreaudiod

     

    To restart the audio daemon. The sound should come back instantly and keep working on reboot.

    Out of curiosity, did you try Repairing permissions using Disk Utility before manually changing with chown?

     

    I realize that wouldn't help with the re-linking, though.

    Of course, I did it with no success at all!

     

    I tried almost everything available with Onyx which was not harmful. Clearing all the caches etc...

     

    Only dyld cache rebuild did the trick (done with Onyx though, but I gave the command line in case of )

    I forgot to mention that I even changed the logic board due to a graphic chipset failure and the problem was already present before exchange.

    I had the same problem, I tried everything in here but did not work for me. What worked though was to plugin your headset, open activity monitor then force kill coreaudiod process, monitor the volume icon closely, once you see that the voilume icon disappears, immediatly remove your headset by pluggin it out.

     

    It took me a couple of tries before it went back to normal. Hope this helps.

    Mac OS 10.8.3 finally solved the problem for me.

    This is broken for me as well.

     

    Through trial and error I found that uninstalling the DisplayLink (DL-3xxx) driver for my Toshiba Dynadock resolved the issue.

     

    Of note is that when I start up with the driver installed and I Option-Click the Volume button in the menubar, it says that the output device is the dynadock, even if in settings I have it setup for headphones.

     

    After killing coreaudio, the volume button is restored to working order (until reboot) and Option-Clicking it in the menubar now correctly states that the output is the headphones.

    The headphone trick worked for me too! I am running 10.6.8 on a 2009 Macbook Pro. I tried all of the other options described in this thread to no avail. My computer randomly got the greyed out volume control after a reboot. Appreciate the tip on plugging in to fix it!

    Tried loads of other methods and this have solved the problem permanently for 3 restarts so far!!
