The below linked article is from Apple.

PRAM is already Reset.

May be Reset SMC will help.

Best.

Launch Activity Monitor from your Utilities folder...start looking a processes...see anything?

What happens when you kill "coreaudiod"?

AKC87, thanks for your persistance and post.

Unfortunately, this didn't end up working for me. I tried a variety of things and ultimately, it was a solution based on this link:

BUT, what I did was hit play on my music in iTunes with my headphones plugged in, opened the Sound preferences pane in System Preferences, then I unplugged headphones and plugged them back in, then unplugged them again, until eventually sound came back on the internal speakers. Had to do it about 3 or 4 times.

Some additional info: 2010 MacBook Pro 17" (Model 6,1), just upgraded to OS X 10.7 Lion, started when I unplugged my Cinema display from the Mini-DisplayPort, and sound was unavailable even after trying all the things AKC87 mentioned.

Hope this helps save someone else serious frustration.

If the headphone jack turns red

1. Open itunes play music with headphones for 10 secs

2. Open system pref pane

3. Unplug and replug Headphones 4 times

4. Then twist headphone plug while plugged in clock wise

This will reset your Headphone jack

After trying everything - this worked for me too.

I lost my audio after upgrading to 10.8 on my 2009 17" MBP.

The only thing to add is that I rotated all the way around about 6 times before it would work. I don't know why this works - but it did for me.

Good luck.

My sound was working perfectly fine until I unplugged my headphones while playing a game on my Macbook Pro 15" Mid 2010. I had the red light at first but now it's no longer there & no sound comes from my computer, be it through the speakers or headphones. Only the startup sound plays. Before I could almost here music playing through the headphones if I jiggled it around but that's not the case anymore. System preferences shows "digital out" as my output and I've tried everything listed here. I can't reset the SMC because my battery isn't detachable like the older models.

I have no apple care and as a 21 year old unemployed college student I definitely cant afford to replace the logic board. Any other solutions??

BUMP

Had this problem on my Early 2008 White MacBook (10.5.8). Tried everything on the page, Sound Output still stuck on digital out. Kept plugging and unplugging headphones, twisting the headphone plug, and eventually exerting a little bit of force sideways in a circular motion with the headphone plug (like I was reaming the headphone socket). Lo and behold, "Internal Speakers" are back.

DAn.

Hello AKC87,

Like you, I have done EVERYTHING you did; but the only way the sound worlds on my 13" (late 2011) MacBook Pro is if I use the mini jack with headphones/external speakers, otherwise its such on optical digital audio.

Not even, the seeming reliable Toothpick trick seems to be working for me? Surely working toothpick cannot be that challenging??

Wanted to ask about the red light too; this does not seem to be perminant either? Whether its illuminated or not, System preferences says I only have optical digital audio available.

Could it because I have a dual-boot through bootcamp? Surely not?

I have tried firmware updates too, nothing... its really getting annoying as I am an BIG apple-punter amongest my PC mates; now I am starting to look super-stupid.

PLEASE tell me that its not a "lucky / unlucky" situation!?
