Macbook Air Audio Output Device Gone

My sound on my mid 2013 MBA has gone. Under prefeerences, there is nothing under device output. I have restarted several times; no luck. I looked under Mac HD, library, prefs, audio,; but could not find any audio files to delete as per one thread. Under utitlites went to audio midi etc, but could not find any listed audio output device list. I have repaired disk permissions. Done a shut down and restart. But still audio is greyed out, and no devices show up under system prefs, sounds, for output device. PLEASE HELP... I am in Zambia and closest apple dealer is in S.Africa. Thank you.

MacBook Air, OS X Mountain Lion (10.8.5), 13" Mid 2013 model 256 flash

Go step by step and test.

1. System Preference > Sound > Output > Internal Speakers

Highlight Internal Speakers / Headphones

Make sure that Mute is not enabled.

2. Remove the headphone.

If you see red light in the headphone port, plug the headphone

in and out of the port 5 or 6 times to flip the microswitch inside.

Sound output may be stuck in the digital mode.

3. Reset PRAM. http://support.apple.com/kb/PH4405

4. Reset SMC. http://support.apple.com/kb/HT3964

Choose the method for:

"Resetting SMC on portables with a battery you should not remove on your own".

5. Applications > Utilities > Audio MIDI Setup

Audio Devices window

Side Bar

Click the Built-in Output.

Under Mute any of the boxes checked? If so, uncheck it.

I have tried all your suggestions on my MBA. Still nothing. I wanted to put screen shots for you to see, but don't have an email to send to. Please see if you can help any further. I really do appreciate your help. Thanks in advance.

You see in my pref/sound/output and input... there is no list of any device and everything is greyed out and muted and it's greyed out too so can't unmute it.

On audio midi it's same story. on side bar no list of any devices at all.

Any suggestions?
