    If you use headphones, does sound work properly?

    Are you seeing the usual images on the screen when adjusting the volume?

    Create a new user account. Log out of the current account and into the new one. Does sound work here?

    Alright. At this point, there's a few options.

    You can copy your data from the troubled user account to the new one, then delete the original. See this article for that:
    http://support.apple.com/kb/HT3309

    Scroll down till you see "Transferring files from one account to another on the same Mac."

    The other option is to try deleting some preference files to see if that brings any joy. Personally, I'd move the entire Preferences folder, log out and back in to see if the problem cleared up. If you don't want to go quite so far, go here:

    <your home folder>\Library\Preferences and delete com.apple.SoundPref.plist

    then log out & back in to see if that helps.

    I've had this problem a lot (can be found http://discussions.apple.com/thread.jspa?threadID=1847650 there as well, but I can't reply) and I think it's just a bug in the system. It's pretty easy to fix though without having to create new accounts or reinstall the os or do anything crazy. Here's the trick that always seems to work for me:

    Open up your Applicaitons folder, and find the "Utilities" folder with in it. In there is a utility called the Audio MIDI with a default icon of a keyboard. Open that puppy up, and at the top you'll see two tabs. You want the one on the left, the one that gives you sixteen thousand different options for selecting inputs and outputs. The screen should be divided into two columns, with a bunch of drop down select menus to choose internal speakers, or the on-board mic, and what not. There's also a selection menu for the sample frequency, which reads in KHz, something like "48,000 or 44100 or 32000" etc. All you have to do is change that number to a different frequency. Restart. Hopefully you've unlocked your sound and volume control.

    If you need to, you can go back into that utility and change it back to default, or sometimes I have to pull the three (M, 1, and 2) sliders from the 0 left to Full right manually, but it always seems to work for me. Hope it helps you!

    This worked for me. Thanks much for the tip.

    In regards to sample frequency.

    Standard Audio CD's are 44.1kHz 16-bit
    DVD audio can be 48 or 96kHz usually 24-bit.

    Most standard computer audio is 44.1 16-bit.

    So, it would be good practice to go back to 44.1 after you flipped the sample frequecy to reset the volume adjustment.
