Internal Speakers not available in Audio Output

same problem my macbook air 13' output audio no found..... help me what can i do...

Maybe you should check the settings in the Audio MIDI Setup.app

On my computer that application is found in the Applications / Utilities folder

Not really - the diagnosis was correct and your solution worked. Just use the port as usual - as it's not really UNUSUAL for the switch to become 'stuck'.

Just go about your usual workscheme and, should the port become stuck again, you'll know how to fix it!

sound output issue could be 10.8 NOT hardware

In my case

Have already been through dead internal drive, new power supply, top half of screen is dimming.

I have both 10.8.5 and 10.6.8 external boot drives.

I only went to 10.8 because Apple won't accept iPhoto orders from older versions anymore.

iMac 7,1 - 3gb

10.8.5 - itunes 11.1.1

10.6.8 - itunes 11.1.1

I also use Audio Hijack Pro for general sound enhancement and SRS iWow in iTunes

with 2 small Sony SRS-88 powered speakers

Was using 10.8 and all of a sudden sound went flaky. Sound control panel showed it constantly switching back and forth from internal to headphone with the sound actually reversed - i.e. speakers plugged in, played through internal speakers - with no speakers, no sound.

Tried some of the suggestions - zap pram, permissions, audio midi, etc. - no joy.

Rebooted into 10.6.8 and everything works fine.

Rebooted into 10.8.5 and everything works fine so far.

I wonder if Apple has too many ex-Microsoft people doing systems work.

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

This is a dust issue in the external audio jack, the first one on the left side of the MacBook. We cut off the tip of a toothpick (to be safe, just cut it in half), gently inserted it as far as it would go, slowly twisted it a few times, and voila! Volume icon came back on in the right part of the upper bar.

This problem drove me crazy with my 17" Macbook Pro as well. The solution is to trigger the on/off switch built into the audio out jack that controls the switch-over to optical out. I think there was considerable dust and lint inside the audio jack that I sucked out with a desoldering pump. Before I used this technique my computer audio out was continually switching from internal speakers to optical out and back. This fixed the problem.

There are several Apple Support strings that point to this same functional problem with audio on Macbooks. Apple should really consolidate this information into one common string.....or even better send out a user bulletin to Macbook users worldwide.

I have the same screen as you. Neither the internal speakers nor the headphones show as output devices on the Sound screen. The only way I can get sound is if I plug in the HDMI to the TV. That it recognizes.

I have been trawling the support pages (which are terrible) to no avail. I tried a chat with a support rep but gave up after waiting for over 20 mins.

I have the exact same problem and I tried what your all suggesting and its not working. I stuck an end of a match stick in the audio port and I also tried plugging and unplugging my headphones and nothing is working. Please help as this is frustrating.

I've just had the same problem and found these posts really useful. Thanks!

Your audio out plug may be stuck in digital out mode. You can USUALLY 'see' if this is the case if a red light is evident in the port. Even if it's not, you may want to plug/unplug a jack from your headphones, etc., to try to reset the switch (some people have also successfully used a toothpick to 'flip the switch').

If that doesn't fix the problem, call back...
