From one day to the next the sound has disappeared. I have checked the sound preferences and the mute box is ticked but I cannot un-tick it. Under the sound preferences there is are no output devices found and no input devices found. I cannot understand. Also, 2 months ago I downloaded an Entourage Update and it somehow archived/deleted all my emails prior to that - took it to an apple shop, and they could not fix it - " anyway it is a 3rd party software etc.." I am constantly having problems with entourage. Anyway, any help ref the sound ?
I have a solution for you all. This fixed the problem for me. First, make sure you are all running 10.5.5. If you are not, run software update from the Apple Menu. If you are set there, go to Applications --> Utilities --> Disk Utility --> Make sure your Hard Drive is selected on the left hand panel --> MAKE SURE the First Aid tab is selected! --> Click Repair Disk Permissions. This may take a while, FYI. As soon as Disk Permissions have been repaired, restart your computer right away. That fixed the problem at my end. Good luck everyone!
This solution worked perfectly for me. I didn't even have to restart my Mac. The speaker icon just reappeared about 95% of the way through Repairing Disk Permissions. Very strange issue. So glad that's what it was.
how long duz it take ...
Thanks, that worked today for my Mac Air!

Hi,
had same problem - internal speakers just disappeared from sound system preferences. I followed advice on this thread (repaired disk permissions etc) but I it only worked when I did this:
Shut down mac with headphones plugged into headphone socket (made sure they were showing up on system preferences/sound/output device
Rebooted
Opened system preferences/sound/output device and unplugged headphones
Internal speakers magically appeared.
FYI with my problem Optical device was showing on output instead of internal speakers (even though nothing plugged into audio out/headphone socket), and the internal speakers were clearly working as the start-up bong was audible on boot up. If you turn on your mac or pc and there is no bong (and nothing is plugged up to your audio out/headphone socket) you have a hardware problem with the internal speakers
After trying every solution on the net and being able to fix it once I know it was not a hardware problem. Some thing someone started with in one discussion lead me to look into the MIDI Setup. I have reboot my MBA several times and it has worked every time I think this may be the fix.
Step One: Open Applications.
Step Two: Find Utilities folder and open.
Step Three: Find the Audio MIDI Setup icon and open.
Step Four: Under Audio Devices will be the IAC Drive. If it Greyed Out, Select and click on “Add Devices”.
Step Five: If the word BUS is in this box select and remove.
Step Six: Make sure that the “Device is online” is checked. Your IAC Driver Icon should be all red.
FINALLY RESTART. Your sound should be working now.
I had this very same problem. At some point I suddenly realised that I wasn't hearing sounds through my internal speakers and the usual volume keys did not produce 'feedback' when trying to increase or decrease the volume. So I opened my 'System Preferences' and rather than see the usual option of 'Internal Speakers', all I saw was 'Headphones' greyed-out with no other option.
But fortunately the fix is immediate and simple. Plug-in a set of headphones, take them back out again and viola! Inside the 'phone jack is a small optical sensor that 'sees' when a pair of headphones are in the socket. Sometimes the sensor becomes dirty and therefore 'blind' and assumes headphones are still plugged-in when they obviously aren't.
Just for fun, when I applied this particular fix, I opened up my System Prefs again and as soon as I withdrew the headphones, the option 'Internal Speakers' immediately appeared and the previous greyed-out 'Headphones' was gone.
I tried all the fixed above but none of them worked for me. What did it though was to: - turn off my laptop - slightly wet a cue tip and stick it inside the headphone jack to clean it - stick a dry cue tip to in the headphone jack to dry any humidity
Solution 3 sounds like my problme but when i take out the headphones it still dosnt switch back to internal speakers! any suggestions for me?
Solution #3 worked for me! Thx!
Hi,
I do the solution # 3, but its work only with the headphones plugged :(
Could somebody help to me???
Thank you.
I GOT IT. If you have an iphone or anything bluetooth you have to turn them off. I have an iphone, sony bluetooth S9 headphone, and jawbone ear piece in my house. After turning off everything my speakers came back, but the root of the issue is the iphone! You have to make sure that your bluetooth connection in your iphone is turned off. It's easily done! Just click on your 'settings' tab, then select 'general', you'll find the bluetooth link to click, and when there just turn it from 'on' to 'off'.
It's a wonder why Apple has not fixed such a simple issue.
Try it and tell me if it works. If not, then I am clueless.
Good luck,

Hold down on the Apple in the upper left-hand corner of your
screen.
1.
Select System Preferences
2.
Click on the Sound icon
3.
In the Sound Dialog click Output
4.
Click on Internal Speakers (Also verify the Mute
box is clear)
If that does not work then it could be the headphone jack is damaged.

Out of the blue, after the Macbook Pro 2.4GHz working normally for over a year, I get "no input device" and "no output device" indication in the control panel. No spund is coming out except the boot up chime.
Please help.
I reinstalled OS X and lost the sound. No input and output devices can be found.
I am having the same problem. One day watching a video on youtube the sound just cut out in the middle of it and hasn't returned since and am having the same characteristics as the others, although I do not have any 3rd parties except google application (sketchup) which I had downloaded immediatly when i got the air in march. Also since the occurance, when I watch videos streaming online i can load it but it'll only play a few seconds before freezing.
Interesting to hear that other people are having the same problem, but has anyone found a solution to this yet ?
Thanks
i lost my sound onmy Macbook Air Input/Output options grayed out.
I reaired permissions as recommended.. That did not fix my problrem..
I have the same problem with the sound output from my MacBook Air. The problem is intermittent - when I first boot usually the sound is there and at some time after that it just suddenly stops. There is no pattern I can determine which triggers it to stop. When I go to the sound icon in system preferences the internal speakers option is greyed out once the sound has stopped and thus far I have found no way of fixing this problem except shutting down completely and rebooting (even this doesn't always work!).
Help!
The problem is probably due to the internal sound cable connection, see discussion on apple board.
Thanks for the reply, unfortunately it diid not work, and I still have no sound - very frustrating, as I cannot even use skype. Also, constantly have problems with entourage, but Apple say, "well it is a 3rd party software" - is entourage used for any non-apple pc's ??
Already looking at options - anyone got opinions on Levono X301?
same exact problem here
Exact same situation... entourage update and everything went haywire!! ANY answers????
i am speaking from Brazil São Paulo and i have the same problem with my macbook air . I have been trying to fix my sound but i cant. I can encrease my volume.
Sound output controls on keyboard do not work. Sound/Output panel in System Preferences shows "No output devices found", the Output volume slider on the highest setting, and the Mute check box checked with no way to uncheck it. Shut down and start up "corrected" the problem once, but not since.
Same problem, from one day to the next all sound dissapeared from my MacBook Air.
Skype does not work, even in chat mode.
The sound on my MacBooK Air suddenly stopped working today. The internal speakers are gone, and external headphones are not recognized. I tried repairing permissions with Disk Utility but it did not fix the problem. (1.8 GHz MacBooK Air, running 10.5.6)
