Q: How to UNLOCK volume (have tried almost everything)

My volume has been LOCKED for over 2 days now. I started when I plugged in a charger for a camera or something of my sisters into the speaker port (on mistake)

 

Now since then I've not been able to adjust volume (it's greyed out with the no-smoking looking sign - I can upload pic, but I'm sure most of you know what I'm referring to). I can mute/unmute it, but volume remains locked and nothing to be heard (the speaker changes as it should when I'm hitting mute/unmute, but it remains greyed out, with no smoking-like sign and no noise)

 

I've tried essentially everything, and nothing has worked...

 

I've ran thru these set of procedures I came across (maybe they can help someone else):

 

1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.

2. Run Software Update and make sure you have a fully up-to-date installation of OS X.

3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.

4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)

5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.

6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.

7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.

If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.

8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.

9. If you have a MacBook Air, turn off Bluetooth and restart.

10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do notappear in the login screen. If they do, the system is still in safe mode and sound won't work.

11. Reset the NVRAM.

12. Reset the SMC.

13. Triple-click anywhere in the line below on this page to select it:

/Library/Preferences/Audio

Right-click or control-click the highlighted line and select

          Services Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select

          Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.



Can anyone help me? I've also followed an app creating process that didn't work. I have no red light coming from port. When I quit coreaudiod I have to force quit and it either does nothing or closes out some apps and resets my menu bar then i get error messages about something closing unexpectedly that I cannot report, close, or see more options. PLEASE HELP THIS IS DRIVING ME CRAZY. MBA 11in mid 2013 OS X 10.8.5

    Also when starting up and resetting NVRAM I get the startup chime - then right into a speaker clicking noise. Other times starting up I usually do not get chime.

     

    And when I rebooted with Safe Mode for the first initial second or two upon logging in the speaker icon up top (beside the battery icon/time machine icon/bluetooth/etc. appeared unlocked - not greyed out like usual), but then returned back to it's greyed out appearance, and locked, useless function

    Your hard drive has failed. Take it to an Apple Centre for a free diagnostic.

     

    When/if you replace it, restore your files from your backup.

    Why would it have failed? So there's nothing I can do now?

    All hard drives fail eventually. It's a question of when, not if.
