MacBook Air no audio output device found ???????? *please help*

i deleted the file as suggested (~Library/Preferences/com.apple.BezelServices.plist) and powered down, restarted, and the icon came back, everything normal again!?)

i don't know if or how long this might last but working fine now.

i am using a 12" macbook pro G4, 10.5.5

Hey everyone,

I had the exact same problem described by all of you, and here is what worked for me. It started yesterday and my audio completely stopped working, including the internal speakers, headphones, even the internal mic. To cure this, all I had to do is install Onyx and clear the Audio cache. It's been a couple hours since I fixed it, so I hope it sticks, but it doesn't seem to be a hardware problem at all. Even though I have a 12" Powerbook G4, it had the same symptoms as your Macbook Air's.

Due to the recent occurrence of all these problems (from date of post) it seems to me that this is either faulty software or some malware that has finally found a way to infect Macs.

Sure hope Onyx works for you!

Hey

I've had this problem for about 2 weeks now. No audio whatsoever, not even the chime. I've tried Onyx but it hasn't worked. I've uninstalled QuickTime and the reinstalled. This also hasn't helped. Each time i boot up i hope and pray it'll have sorted itself out, but as yet it hasn't! Does anyone have the answer!?

I'm outside my warranty, so have been putting off going to applestore as i'm certain it'll cost me small fortune to get this problem fixed. Does anyone have any ideas...? Please....

I'd make an appointment with the local Genius Bar and see what they say. If they say it's a lot of money at least you will know and can make a decision. It might be something simple. The geniuses are pretty helpful. In my case they replaced the entire MBA (a good reason to purchase Applecare) but maybe in your case it's something simple and they just tell you.

You won't incur any charges without your consent. Go see them.

Mine has been doing the same thing for the last 2 weeks. I take classes online and it's kinda hard to do that when i have no audio, it's the same thing won't play youtube, and when i try to turn the volume up it's just a circle with a slash thru it, apple needs to do a recall and fix this problem cause obviously it's not just one person....

Update: I brought it back to Apple and they replaced the sound board and the cable connecting it to the main board, and all is fine now.

It's a hardware issue, just bring it back to Apple and they will fix it.

Hi,

Same problem here. Warranty is still on, but leaving my computer for week is not an option for me. Maybe I would buy another one and then take this to Apple.

Anyways, I had also a problem since some applications refused to launch without a sound device. I installed Soundflower (is is free, open source) and now I can launch those apps and watch Youtube videos. Without sound, obviously. Hope this helps.

Same problem as everybody else. Problem started on Dec. 23. Yesterday I took my laptop to the Apple Store in Manhattan. The Genius wasn't surprised at all. They are getting tens of computer with the same issue. They need 5 days to order the parts and 3 days to service the computer. The parts to be replaced are:
Item # Description
922-8379 Audio board
922-8380 Audio board flex cable

Here's a baffling situation. After weeks of no audio on the MacBook Air, after a normal restart this morning after being in sleep mode, THE SOUND CAME BACK! I did absolutely nothing different this morning from any other morning. No new software was downloaded. We'll see how long it lasts!

Same issue on my MacBook Air . . . no audio and Flash playback halts after 2-3 seconds.

Into a service center for part replacement I guess . . . but c'mon Apple . . . please post some official instructions.

Wondering if this could somehow be a heat related issue. In an earlier post I indicated that the sound mysteriously came back this morning on a restart after several weeks of no audio. After being on all day, the sound started to fade and disappeared tonight. I noticed that the bottom of the Air was very hot. I'm going to try putting a fan under it tomorrow just to see if it makes a difference.

Hi to all .
from yesterday i 'm having the same problem ..no audio..
i tryed all the ideas this forum had ,but nothing worked...do you think tha the flex cable needs to be replaced ?..any new ideas ?

thx...

I have *the same* problem with my IMAC G5
flash videos stop playing, no audio device output, etc, etc.
This is not only with MBA.
And the issue come and go with the time.

I think that this is hardware issue because the temperature is to high and with the time the cable and the audio board stop work.

Sadly, my machine has been into the shop, and back. Replaced a hard drive and a logic board, and the shop guys said it was working. Back home -- nada. No icon, no input, no nothing.

This is just amazing, and not in a good way.

Craziness continues. Our MacBook Air's audio icon came back suddenly about a week ago but by the end of the day it had disappeared again. Since then, the icon will appear but not always with sound. When the icon is showing it will let you play YouTube videos, etc., but not always with sound (when the icon is gone the videos won't play). Based on the other replies I'm reluctant to take it in for repair even though I have an Apple Care policy on it. This has become very frustrating.
