My MBA lost sound for 2 months and I tried all suggestions given here to no avail. I ordered the screw driver and audio cable but before they arrived the sound has come back out of the blue... only thing that could have happened is an iTune bug, once the new update has been installed the sound came back.
So my laptop stopped working a year ago so I took it to an IT engineer, they said that the motherboard needs replacing. So they replaced the motherboard and it began working again. So when I brought it back home I was playing a video and realised that the sound wasn't working. I tried setting the sound in system preferences, then rebooting it, I feel like I tried everything. So I took it back to the IT guy and he still hasn't done anything to fix it says he needs more time. He said he tried reinstalling the software which did not work so now he said he'll try other ways. Can anyone tell me what else we could do to solve this problem? I don't think the IT guy will be able to fix it.
This probably would have fixed the problem, but it asked for a username and password and so I put it in but it said it was wrong, and my laptop is owned by my school so I have no idea what the crap that username and password is.😠
I tried nearly everything non too technical in this thread. Gave up so decided to just shut it down and forget about it awhile. Came back about an hour later and turned it on and the speaker indicator (ie input audio device) came back on!!!! wow... why though? hope thats it and it doesn't disappear again.
I have the same issue. No sound, no audio output. Watching videos works fine now, but was a problem before.
Anyway, I've tried the fixes that I have found here and it doesn't seem to work. So maybe it's a hardware issue. But this sounds strange, as this happened before, but then I just restarted the computer and the sound came back. But now that easy fix doesn't work.
Anyway, if it is a hardware issue, what would it be? I have a Macbook Air mid 2013, and this model doesn't really have an audio cable if I'm not mistaken?
Same problem here for a few days now. No sound and also got "bluescreens" (no Kernel-Panic!). The screen just turns blue an a little loading-graphic appears, but nothing happens.
This is really strange, anyone got contact with apple if this is an hardware issue?
Maybe you could check another thing that is a little strange: since I've got these issues with the sound, I can't watch flash-videos anymore. Try to watch a movie on YouTube. It stops after a few seconds.
I have a similar issue, (1) I have no sound from either my internal speaker or from headphones, (2) the volume control does not appear in the menu bar, (3) opening garage band brings up an error code "Core Audio: Selected Driver not found. (-10202)", (4) in iTunes I cannot play songs (the tiny speaker icon to the left of on the song shows volume but the timeline at top does not advance), (5) same youtube issue (appears to start but stops after a second or two), (6) some other video (for example ABC full episode player) will play but no audio.
I tried (1) cold boot, (2) zapping the nvram, (3) reinstalling quickplayer, no change. The other threads are for other hardware and refer to a headphone jack reset issue, but that seems to involve different hardware (there is no "red indicator light" on the mba).
This problem appeared out of nowwhere, it happened after (but not immediately after and apparently not associated with) installing itunes 8.0.1.
From about 2 October my MacBook Air developed the same problems as described above: no sound output and (flash) video playback issues.
Pressing the volume buttons on the keyboard flashes up the level indicator on the screen but it does not change, and also a little "O" with a line through it appears underneath. The Sound Preference panel says "No Input Devices Found" and "No Output Devices Found", and the volume slider is grayed out, set a max, with a grayed Mute box ticked.
Flash video on various sites plays only for a second or two before stopping, although the file continues to load in.
The only software I've installed around the same time this problem first occurred was CoolIris. I have since removed it using its Remove option in one of the menus.
I have also had system crashes when trying to wake from sleep. The machine gives the blue screen and either locks up, or freshly reboots to the Login Screen (with previously logged in users now logged out, ie a restart).
I think, but am not 100% certain, that I updated iTunes after the problem first appeared.
It's a hardware problem. And it's becoming a widespread thing, from the looks of it.
It happened to me last June. I tried everything you guys did, to no avail. So I took it to the local Apple service center here in Manila and they did determine it was a hardware problem: the audio board and the flex cable were screwed.
So they replaced two things: Audio Board (Part No.922-8379), and Audio Board Flex Cable (Part No.922-8380). I got it back and it worked fine.
Here's the kicker - last month it happened AGAIN. Apropos of nothing (no installs, nothing new software-side), the sound quit working, just like the last time. What was new was that I got a kernel panic after I woke up the Air from sleep, and then when I restarted, no audio. Again.
(I don't know if this is significant, but the night before, I was oddly getting double-audio out watching something on VLC. The audio was echoing or repeating a second later. Thought nothing of it at first.)
Now it's borked again, and I have to bring it back to the shop. Not in a hurry, because audio isn't mission critical to how I use my Air, but it sure is a bummer.
I make do for the meantime with a USB iMic from Griffin, and earphones or external speakers if I need audio, but it's really bothersome to have use a dongle just to get audio.
Apple should really look into this. I have half a mind to write about it in my newspaper column and raise a stink. Hey, I think I will.
It all looks like a epidemic failure without any direct influence of user behaviour. When my audio screwed up, it was the same thing coming from sleep mode like thousand times before.
The main objective of this threat from my perspective is to find an effective countermeassure. Agabot says only through component change, so i do hope we will get some more feedback to confirm same/similar cases.
And by the way: Audio is a basic function and for me it is critical !
Thanks

I agree! I've been following this thread very closely, ever since yesterday morning when I lost my sound entirely. Suddenly, the icon is gone -- and I know I didn't cause this. I've since zapped the pram, restarted, restarted, restarted ... searched the other forums for a clue ... and now this is harsh news indeed.
Also, YouTube videos -- in addition to no sound -- are not running. Maybe that's a small clue that it's software instead of hardware? I am
so hoping to see a fix from Apple via software updates before I have to take this in and leave it at the store.
It would be cheaper to get the dongle described. But how can it be a hardware issue if the dongle works? Clutching at straws, I know ... but more info would be great, at least for this misery-loving company.
I agree, with all due respect to agabot, this seems to me a software problem even if his was a hardware problem. I cannot get any sound out with headphones or external speakers, no sound. It would be nice if someone from Apple would weigh in
