no sound + red light in headphone jack

i don't know if this will work for you.
but i tried the others above (except for the toothpick-ing)
i tried inserting the headphone jack several times and the red light is still there.

my headphone has 2 jacks (the other one is for the microphone)
I tried to insert the mic jack to the speaker hole and pressed VOlume up and VOILA! the sound is back 🙂

hope this would help.

i advice you not to try the toothpick-ing :))

The toothpick thing totally works.

Hi there,

I just read your post about the red light on the output jack and that is no sound on the computer only if you use a headphone you can listen.

Well, I'm having the same problem and I'm wondering if you solved? If so, could you tell me how?

Thanks

I had the exact same problem.
No sound, red light out of headphone jack and death circle comes up when I tried to adjust the volume. External speakers and head phones work, but when there's nothing plugged in, no sound.
I looked on all the chat rooms, looked at all the advice; move the headphone jack in and out quickly, slowly, used a pen cap, a toothpick, a q-tip cut in half, putting the headphone jack in the other port and back again, putting something in the USB port then take it out and try it again... nothing worked.
I called applecare and he pretty much told me it was a physical problem and needed to be brought in to an Apple store. Pain in the ***, I'm at school and there's no Apple store here. I would have had to wait until reading week.
Then a few days later (today!) I tried it again. a Q-tip cut in half and put it in very gently and bingo, everything works!

So I do feel your pain, but my advice is keep trying, the Q-tip worked for me, and keep trying!

Just did the put speaker jack in and out quickly thing and BINGO!! Got sound back! this is a weird problem!

After spending a good two hours trying to solve this problem (twisting the headphones every which way, putting them in and adjusting the volume then removing them, etc.), I finally fixed my problem. I was worried about putting a toothpick into my computer, but, luckily, I fixed my problem without having to resort to that! All I did was put the headphones in and pull them out quickly a few times. Now there isn't a red light and my volume works fine!

Thanks for all the advice 😀

oh man! I have the same problem with the red light. NOTHING is seeming to work though! Any other suggestions?? Thank you!

After about 30 minutes of playing around with a toothpick I think I've figured it out! If you look closely into the jack you can see two sensors fairly close to the outer edge, one on each side of the headphone jack. So, if you, instead of poking around, swirl the toothpick so that it touches both sensors (and you don't even have to push hard) then the problem was fixed.
Hope this helps!

I had the no audio, red light beam problem for about 6 months. I felt I had tried everything and had no options left. I decided to try the paperclip idea that someone had suggested and IT WORKED!
I took a paperclip, unbent the end, and stuck it into the audio port. About 4 or 5 millimeter into the audio port on the right side there is a small hole. I stuck the paperclip into the hole, felt a small click and my audio began working again. The red light is now off and I'm having no issues with the audio.

I am having the problem with no sound, no playing songs in itunes, did you fix yours?

I've had that problem too (red light, no audio). For me though, it seems to only happen when my MacBook is really hot (I think the material on my couch doesn't disperse heat at all). When I put my computer on a cool surface, the audio fixes itself.

I will try that.

I just noticed mine stopped working last night cuz i was playing a game the night before and it was okay. So I googled it and ppl had suggested that I use the end of a q-tip or the jack of the headphone to push in the little metal thingy's but it did not work for me. What is wrong?

still not working. its showing its muted when its not! any ideas? help me!

This is a really great tip (no pun intended) After trying for days to find the answer to this problem, the Q tip has solved the problem. I have sound & no red light. Many thanks

Unplugging and replugging my headphones caused this problem to go away on my black MB. I didn't realize there was a mechanical switch in there that detects the presence of a digital audio device. I guess my laptop is getting a little old, and it's gotten a little dirty in there maybe.
Thanks for the heads up.
