    Hey

    I had the same problem on my MacBook. The sound just stoped working. I brought it to the apple store and they did a fresh install. After the sound worked with the headphones but not the internal speakers. so they replaced the logic board ($400). It all worked good until I restored from my time machine back up. My backup was from after the sound stoped working, so I tried one from before the sound issue. Magically it worked again. I then just restored my recent files individually (not OSX again)

    About a week ago it stoped again. I restored from a backup and it's worked fine since.

     

    So before you go to the apple store to get it fixed, if you have a backup try restoring to it. Then just copying your files back. If you don't have a backup you could try doing a clean install of the latest version of OSX, then putting your flies back on. The only thing with doing a clean install is you would lose your preferences (you wouldnt if you restored from a full time machine backup)

    Having the same problem, but I am not sure if the fix applies to late 2010 MBA.

     

    Is the audio cable replacement fix applicable MBA A1369?

     

    Thanks!

    Okay so I checked on another forum because my headphone jack also had a red led light on inside (never noticed that before) and it said that my the 'Digital Out' is enabled and in order to disable it i should wiggle a matchstick inside to release the switch.

     

    Now i know what you're saying " I spent over a grand for her and I have to fix my favorite child with a **** match stick" well i totally agree with you. It's crazy but it worked.

     

    So before you buy anything or disect your infant... TRY IT!!! Hope this helps.

    Thanks Snow,

     

    But I can't understand how it happened just after I reinstalled Mac OS. Just a coincidence?

    I went to an Apple Store and the Genius reseat all the cables and audio came right back.  All done in 15 minutes. Frigging awesome!

    I have a 2008 MacBook Air.  The sound icon disappeared and the sound just went out on it a few days ago for the first time.  I went to this forum and tried various things that seemed to work temporarily like a safe reboot or even removing a line from my Library Preferences.  But I am now thinking that those might have been coincidental because last night when it went out right in the middle of something I was really into, in frustration, I slapped teh casing and the sound came right back.  It kept happening and I kept slapping it and the sound came back every time if I slapped it enough times. Never more than a few so nothing abusive here.  Then, by chance I grasped it by its lower right corner and noticed that if I held the casing firmly together at that point the sound worked consistently.  I know very little about computers and I live four hours from the nearest Mac store.  But, logically, this seems like a wiring issue, so I am going to try the advice given by several of you to go to ifixit.com and try to replace the audio cable - first by going through the motions as though I was replacing it as suggested by one person, then, if that doesn't work, by ordering a new cable and replacing it.

    how much did you pay for the applestore to change the 3 major audio hardwares?:)

  • kfmcmahon Level 1 Level 1 (0 points)

    I think mine, along with some others above, is definately a wiring issue (connections coming loose from time to time) as I lost audio recently after plugging in a USB SD card reader (which is right next to the headphone port).

    I tried the restart while inserting some headphones and jiggling it on startup and voila it worked!

    This happens from time to time and despite opening up the case and detaching/reattaching the audio/speaker cables and its fitment to the sound card.  Somehow a loose, faulty cable connection,

    i think.

    My daughters MacBook air 13 inch had the sudden loss of sound two months ago and the sound cable and logic board were replaced under warranty. Two days ago it was back. No sound ! Tried

    1. Restart

    2. Safe restart

    3. Resetting the pram

    4. Repaired permissions with apples disk utility, Mac cocktail

    5. Used onyx to clear the audio files

     

    No joy and no sound!

     

    Then I read a thread about sound loss in other macs and deleting the following preference file:

     

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

     

    Deleted the file and restarted the MacBook air and the sound was back!!! I hope this helps you all

    Has anyone experienced this on a 2011 MBA?  The model doesn't really have an audio board or audio cable persay so I'm not sure what might be the issue...

  • Shadow_2k Level 1 Level 1 (35 points)

    The 2011 MBA is also affected by this error. Either the I/O-Board cable is loose or the I/O-Board itself is damaged. There is a picutre of the I/O-Board on ifixit.com.

    a very likely fix:

     

    open a terminal window (final "Terminal" application), and paste in this command, it will fix it:

     

    sudo kill -9 $(ps A | grep coreaudio[a-z] | awk '{print $1}')

     

    basically it kills the coreaudio process in mac and it will automatically restart, then fix the problem.

    I am sure it is not hardware.

    I had the same problem. No sound and no icon plus the youtube problem and the itunes does not work properly.

    I tried everything: deleting these librery/user/preferences files, inserting a wood stick by the earphone hole... nothing happened. But there were something strange: when the system starts up, the icon illuminated and after finishing the start up the icon became grey.

    I just rebooted the system and now the volume works.

    Could it be a virus that affects the volume wire or something similar?

    I fixed it with no changing hardware, then I am sure it is something strange. This is the reason I think it could be a virus.

    Thank you very much to all of you
