Red light in headphone jack and no sound from internal speakers.

Don't forget (like I did !) to repair disk permissions in Disk Utility after the surgery

Works!! Thanks!

Hi, I have the same problem but using this method I can't disable the digital output and I don't know if I'm doing something wrong. I have an iMac Late 2013 running Yosemite. Please help me!! Thanks

My item for example is item 6 using profiteer

Thank you SOO much haha, I can't believe I didn't think to do that.

Just had the same issue... blowing very hard for several seconds into the output jack works perfectly. just put my lips to the computer and sealed my mouth on it, and blew super hard. It actually works.

Can you find a solution for this?, and there is more than one item that have the "Cirrus" description

I had this problem too. I tied the poking, prodding thing and everything else listed here...then by coincidence when I was trying to fix something else (frozen boot bar)... I did the following and my sound started working normally again

Resetting NVRAM

1. Shut down your Mac.
2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
3. Turn on your Mac.
4. Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
5. Hold these keys until the computer restarts and you hear the startup sound for a second time.
6. Release the keys.

After resetting NVRAM, you may need to reconfigure settings for speaker volume, screen resolution, startup disk selection, and time zone information.

It may be worth a try

I just blew really hard into my headphone jack and it worked great

thankyou, tried everything in all the other cmoments and then saw your comment, blew on it hard and sound came back within 3 seconds

I turned my mac by putting the audio input up. Then plugged in a jack a few times and it worked - the speaker sound was back.

Finally after trying everything mentioned on thread "Blowing air into the port" worked for me too. Thanks a lot. :-)

I tried all methods written in this topic and still no have solution. Does anybody have a new solution? 😟

MBP running Yosemite, then El Capitan Public 1

Hey, I have a 17" MacBook Pro (Late 2011) running OS 10.10.2 and had the same thing happen, but only my headphone jack port stopped working. The internal speakers were fine. But if everyone else's suggestions don't work I have a new cheap fix!!!

I looked it up and saw that people said to twiddle a toothpick or whatever in the headphone jack port. I tried that with a paperclip and it worked. But the next day it happened again so I used the the paperclip again. It worked, BUT I must have damaged a component so everything sounded garbled.

I went to the Genius Bar to see if there was anything they could do but all they suggested was to replace the logic board which costs nearly $800 (AUD)!

NOW FOR THE CHEAP FIX!!!

A friend of mine suggested I use a HDMI cable because they transfer video and audio. I got a Belkin Mini DisplayPort to HDMI Adaptor as well as a HDMI cable and connected it to my monitor. Then go to Sound in System Preferences. Under output, select your monitor. Then connect your headphones to your monitor's headphone jack port! Et voilá!!! $50 worth of cables fixed my problem. . .

The volume isn't exactly as adjustable as it was before. . . But hey, it works and saved me $750!

This fixed it for me, after twisting the headphone plug, blasting compressed air and poking around with a toothpick didn't.

Thank you!
