    I'm on my iPad right now so if something I say doesn't look quite the way it does on your Mac forgive me. Go into your Sound preference pane and click the Input tab. Make sure that built in mic is selected and mute is not checked. There should be a slider control on the screen, slide it all the way down and then all the way up, and finally slide it back to about a quarter of the way up. See if you sound works now.

    Hello, thanks for your help, but it did not work! = (

    I can not move any slider, and also, I have no options for device input and output, they do not exist ...

    Already tried everything ... but anyway, thank you!! =)

    Try resetting the SMC and pram

     

    MacBook and MacBook Pro 

    Laptops with a battery you can remove 

    Shut down the computer.

    Disconnect the MagSafe power adapter from the computer, if it's connected.

    Remove the battery.

    Press and hold the power button for 5 seconds.

    Release the power button.

    Reconnect the battery and MagSafe power adapter.

    Press the power button to turn on the computer.

     

    Newer Mac portables with a battery you don't remove

    Shut down the computer.

    Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

    On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

    Release all the keys and the power button at the same time.

    Press the power button to turn on the computer.  

    Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

     

    Resetting NVRAM / PRAM

    Shut down your Mac.

    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.

    Turn on the computer.

    Press and hold the Command-Option-P-R keys before the gray screen appears.

    Hold the keys down until the computer restarts and you hear the startup sound for the second time.

    Release the keys.

    I did all the steps and decided not ... I did 3 times ...

      Still no sound ... or the sound of the headset works ...

    thank you very much, you were very kind.

    and sorry for my bad English! =)

    The sound on your headset works? If you look into the port where you plugin the headset is there a red light on inside there? Don't worry about your English, we'll work through it.

  • Luisek Level 1 Level 1

    Hello, the headset is not working well.

    And do not have any red light at the entrance to the receiver.

    I think not fixable! =(

    In your sound preference pane under the sound effects tab do you have internal speakers selected?

    I keep hoping someone else will offer some help here! Try the steps listed here http://support.apple.com/kb/TS1574

    And maybe try creating a new user and logging in as that user to see if the problem persists.

  • Mike Sombrio Level 6 Level 6

    I have an idea. Go to Users - Home (your account) - library - Preferences and find and trash the file com.apple.soundpref.plist

    Now open your sound preference pane and see if that makes a difference

  • Luisek Level 1 Level 1

    I did just that, but not solved.

    File not open

    I'm sorry, my last idea would be to reinstall OS X? Do you have your install discs? If that fails I would have to suggest that you take it to the nearest Apple Store and have them take a look at it.
