Mac OS X Lion: Sound problem after unplugging my headset/headphones.

Running 10.7.5 and still experiencing lost audio.

Also having this issue. Closing all applications did not fix it. I also tried logging out (Since I have 2 users) but I did not get any response in sound when trying to turn my sound up and down with the F11 / F12 buttons.

Running 10.7.5
MacBook Air 13" Mid 2011

1,8 Ghz Intel Core i7

4 GB 1333 MHz DDR3

I had the same problem, had a look on utube and a guy posted a fix that worked for me. Nothing more complicated than using a tooth pick to insert into the headphone socket, preferably with some music playing so that you can hear when it's fixed. In my case I inserted the pick pretty much all the way to the LED at the end and then applied an outward pressure for a few seconds and bingo! I pressed down at about 6 'o'clock and that fixed mine, but others say at 9 or 3 'o'clock, a left or right pressure in those cases. I guess you may have to try various positions but in each one hold it for several seconds rather than prodding about! Good luck.

I have a 2009 MPB 17" w/SL 10.6.8 ; this happens intermittenly w/me. In the past my only resolve was power cycle. Expirimenting I found this to work:

Symptom:

After using headphones and unplugging the macbook pro speakers will not work. Either the keyboard volume is unresponsive, the volume is much lower than should be, or there is no audio from the speakers at all.

(my) Resolution:

Plug back in the headphones, verify they work at volume and with system volume control as normal. Now WHILE using keyboard volume + or -, getting the 'plop' 'plop' 'plop' sound indicating volume shift in quick succession, unplug the headphones. Now your speakers should return to working as desired.

This fix has worked on several occasions and not failed to date. A bit ghetto, but beats the pants off a power recycle in the time dept.

I LOST ALL AUDEO OUT - WENT TO midi AUDIO OPTION AND FOUND THAT ALL HAD BEEN SENT TO "MUTE" UNCHECKED "MUTE" AND ALL IS FINE - NO IDEA HOW THEY WERE MUTED

I had an issue where any type of file action was producing the god awful crinkle/crackle/pop sound. As it turns out, a change was somehow made in my system preferences (definitely not user initiated) whereby the sound effect output was changed to aggregate device instead of internal speakers.

To fix, simply open System Preferences, Sound, and select the Sound Effects tab. Ensure internal speakers are set as your output device in the dropdown menu.

If this isn't your issue, I wish you the best of luck in finding resolution!

hi, I've updated the software and found same problem.

Just go to adjusts/ system preferences and the click in audio tab, what happened to me was that in "output" another sound driver (i don't know why) was selected.

click on speakers and problem fixed.🙂

😮pheww i was panicking

Thanks marcusleemitchell, and the next few users here. We use Logmein extensively and on a 2nd user, not where it was originally installed, the sound had stopped, and for us, it was Preferences > Sound > Output and make sure the 'Internal Speakers' was selected vs LogmeinSoundDriver ... Thanks forum!

I hope this gets understood and fixed by Logmein, Inc., a very fine product, which many of us love!

Hi, folks.

Well, I tried every software solution listed in this thread, and none of them worked...apparently because in my case, it was a HARDWARE issue. Specifically with the headphone jack, which required me shoving a paperclip up in there. Others have mentioned this, but I found that this thread actually has a good explanation for it. Specifically,

"The problem is there is a switch in the jack that tells it if you have a mini headphone plug or an optical plug plugged into the headphone port. The problem is when you remove the plug, the jack doesn't know it and keeps shining the red light to talk with the optical. This disables the internal speakers and you see digital out instead of internal speakers in the speaker conrtol panel. Plugging and unplugging the speakers may get it working right for awhile but it won't last forever."

Plugging and unplugging didn't work for me, so I moved on to the next solution:

"I slid a paperclip in, and pushed out a little metal on the side.

That did the job, and I have internal sound again. And the digital red light, is now off."

This worked perfectly. So, if after you've tried ALL of the other solutions here, if it still isn't working, this might be your problem.

NOTE: This DOESN'T mean shove a paperclip directly at the red light in the back. If you look into the audio port (which is easier if the red light is on), you'll see a metal ring about halfway down. Poking at that did the trick for me.

It has worked... thank you so much, I will never plug it ever again my headphones, never ever

I went to System Preferences->Sound and on Output tab checked Mute checkbox then unplugged my headphones. After that Mute checkbox strangely became unchecked and sound came out from speaker. I hope that will help.

This fix was SO HELPFUL - thank you so much!!!!

Mac Pro Early 2009

This really does work people!!! Just unplug and plug you head phones in and out until you hear the plop noise. You can pause in between pulling it out and turning it up and down for a quick sec to see if it still works. But other than that this really does work!!! THANKS!!!

NO MORE AFK!!!! 😀

sudo killall coreaudiod worked for me, too. Thanks!

I was having the same problem under Snow Leopard after using Logitech USB headphones. Kyen99's LionAudioFix script worked for me, too. What would happen if I changed the file name to AudioFix? I'll never remember to look for "LionAudioFix".
