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

Once you have tried all of the basic things (restart, reset the pram, reset the smc) I had to remove the following preference file.

Delete the BezelServices preferences file – this is a mysteriously magical file. It controls those on-screen images that you see when you change the volume, eject DVDs/CDs, change brightness, etc. But it also seems to be the source of all sorts of odd issues that you can never figure out, and tends to get corrupted. But the fix is easy and relatively safe. Go this preference file (location shown below) and just delete it and reboot. Location & filename:

~Library/Preferences/com.apple.BezelServices.plist

Good luck. This worked on my 13 inch Mac book air 2010 running lion.

My problem seems similar to everyone else's. Just want to confirm, if anyone can help me.

No sound, stopped suddenly, overnight. I woke up, I woke up my MBAir, and no sound. The sound control panel has no input or output options, the earphones do not work, no startup sound, no sound from videos. I ran the hardware test on 'd' startup, said this about audio:

"Intel High Definition Audio:

Audio ID: 0"

I have tried all of the software fixing advice here and elsewhere, started and restarted my Air many times after deleting and doing various things to files and whatever.

So, the thing to do now is install a new cable? That is it? Bit of a problem as I am travelling, but I will have to do that if I need to do that.

Thanks.

Ian,

Different people seem to have "resolved" the problem in different ways, and it is difficult (for me) to understand why - unless the underlying problems are slightly different. However, my problems were precisely the same aas yours. I was not able to sort things out through software / reboots etc, nor did removing the audio cable and re-seating the connectors. But installing a new cable (approx GBP30 on eBay for a "used but functioning" cable does appear to have resolved the problem. (See my earlier post APR-17 above). Using the iFixIt walk through it took ~30 minutes, and only required very basic tools. Good Luck, and I hope you get your MBA working again!

Hey guys,

For me the problem was that LogMeIn updated and somehow set the logmein drivers as the standard for the audio output and the microphone input, so i just changed it back and that worked.

System Preferences >> Sound >> Output and Input

The problem for most of us is all the preferences sound have just greyed and disappeared.... I am trying not to take to an Apple centre but I am sure it is going to be the only solution.

I am quite unhappy with the Apple answer to a problem that is not from the customer....

¿is this apple quality? 😟

I've been wrestling with the disappearing audio functionality in my MacBook Air ( original), an have tried everything in this thread. Resetting the SMC worked, as did plugging in earphones and rebooting - but both worked for a while before the same problem recurred.

But what I noticed is that the problem only recurred when I loaded Youtube to watch a video. Suspecting that Flash might be part of the problem, I have removed all traces of Flash from my system, and installed Flashblock extension in Firefox to ensure no Flash is loaded on browser pages. Immediately I emptied the Trash containing flash plugin and restarted, my sound returned.

It worth a try: won't fix an audio cable hardware problem, but if that cable isn't the cause, ditching Flash might work for you too!

Hi Riaz

I have experienced the same issue and came to the conclusion that my audio drivers have been somehow replaced by the Logmein ones.

You said you were able to changed them back and it worked. I think I should try the same but I can't figure out how.

Can you tell me how you did it?

Thanks!

hi! Well that happened to me today and what i did was i plugged in my earphones halfway then sound came on. i am not really sure if this is the same problem but today randomly, the sound just didnt come on. i checked if the volume was on mute and it wasnt. the earphone trick works. i have done it alot of times. but again i am not sure this is the same problem

This happened to me tonight. The solution for me was to uninstall soundflower - ran their uninstall script then using Path Finder I found anything with soundflower and deleted them. Rebooted and had my audio back. 2011 MBA 11".

I had the same problem, here's how I fixed it; Open Disk Utility, select Macintosh HD (or whatever your hard drive is named), Repair Disk Permissions, once complete-Restart. Sound is back for now. Fingers crossed.

A new record! That fix lasted 10 minutes. I put the MBA to sleep, when it woke up no sound. Getting frustrated.

I've updated my osx, deleted the "bezelservices" file, reset the PRAM, and repaired permissions all to no avail.

Everyone....

This is NOT only a Macbook Air issue, My 15" MBP suffers from this as well as my 2012 Ultimate 11" MBA. The minute I installed Mountain Lion and updated to 10.8.2 this issue began for me. Up until then I NEVER had any audio output failure.

This is NOT a hardware issue, very clear that this is a Mountain Lion issue, at least for me.

I recently purchased the newly announced (2012) 13" model MacBook Air (MBA) and I'm running OSX 10.8.2 with 8 GB of RAM (1600 MHz DDR3). My MBA has a 1.8 GHZ Intel Core i5.

I'm having problems with my audio, which sometimes cuts off and will not work unless I restart my MBA. Similar to reports posted in 2008, if I try rebooting/restarting my MBA that will restablish the audio temporarily. As with some of the reports in this thread, I too have taken my MBA to the Genius Bar only to be told that they will "attempt to repair."

Has anyone faced and resolved this issue and how? Please help!

I was dealing with the same issue. It happened after updating software.

I have a Macbook Air Original running Mac OS X Lion 10.7.5 (11G63) (cannot update to Mountain Lion).

I restarted, deleted the Bezel file, reset PRAM and SMC, and now finally after repairing the permissions using disk utility, the sound seems back on.

So, at least for me, it seems a software issue.

It's not worth it to get a replacement logic board: $599

I think i am having the same problem. I thought it was the audio board so i bought one and replaced it but still no sound. I'm not going to spend $599 on my 3-year old MBA.
