Audio jack problem, no speaker sound, red light

My MacBook has no sound except through headphones or external speakers. When I play a song, a red light appears inside my audio jack and there's no sound. The volume controller in the menu bar is grayed out. I tried poking into the audio input jack as mentioned in many forums, with no luck. Can I fix it by opening my MacBook? Is there any way to fix this other than poking something into the audio jack?

As a workaround USB or Bluetooth audio works independent of onboard audio. A dongle often has a microphone included with line in/out ports.

What a horrible investment. I cannot believe that I paid 3x the cost of a similar Windows machine for something that barely lasts a year. I used to be one of the people that cursed Windows until I met the Mac! By far an inferior operating system. My problem is in software because until I play a sound, my headphone jack stays dark. As soon as I play a sound, it turns red. This is a year old system.

That's not normal; while the jack is flakier than it ought to be, it still usually lasts multiple years. 1 year is well within warranty, so take it to an Apple Store and they will fix it for free.

The more complete the description of your problem is (what exact machine you're using - there are many versions, what OS you're using -there's a lot of those too, what Application you're using there are many, a full compete description, the text or screen shot of any error messages) the more assistance we can provide, and, the sooner we can provide it. ##&&%'n may seem productive but it's not there are many possible work around'ss and solutions - did you try any of them.

The red light in the headphone jack means that the MacBook Pro thinks that an optical audio cable is plugged into the port. Try unplugging and replugging a headphone plug into the port several times. There is a tiny sensor inside the port that determines whether the port operates in optical or analog mode. Plugging something analog in should trigger the sensor and restore the analog signal.

Thanks Ralph... it surely works!!!!

what did you read my answer and then make this response 4 years after the question was asked?

por

I placed the plug in and out a few times and the sound returned on the in built speakers

I tried the headphones solution. But I tried it with iPhone headphones. It did not work at first, even after almost 20 - 30 times. It worked only after I tried clicking the headphones volume buttons. Then I removed the headphones, internal speakers worked fine.

Considering how big of an @%^$$@$ you are, I think a telephone pole would be of adequate size to shove up said @%^$$@$.

(It should probably be noted that the above key combination should be done when the macbook is already turned OFF. It's the startup shortcut to reset the SMC).

just had the same problem RIGHT NOW - i took an air duster can (those pressurized cans that are made for dusting computer components) and i blasted the headphone jack....worked like a charm...i guess there was some dust or debris in there that got in the way and confused the computer's jack....i would suggest trying THIS method before sticking anything INTO the jack or blowing with your mouth (in fact, with all due respect, DON'T blow with your mouth...saliva will get in and RUIN the jack and sticking a screwdriver into the jack will only work against you, imho)

all the best!

Thnx mayer

this tip worked for me.

I had a similar issue today and was so simple the solution I couldn't believe it. I plugged the optical fiber in and no sound, after 30 seconds, the red light turned off. I tested de optical fiber with the TV and everything worked ok. I did the same procedure Greg did: I blasted the port and everything started to work perfectly good! I was 3 seconds before resetting the PRAM and try many complicated tricks. Amazing what a small particle of dust can do. Many thanks Greg!

The Apple 3.5mm headphone jack may have multiple different failure modes, since it contains 4 equally flimsy electrical contacts. Staring into the glowing red Cylon eye, they are: 2 "sleeve" contacts (nearest you), one at 9 o'clock and one at 3 o'clock (positions on an imaginary 12-hour analog clock dial); 1 "ring" contact (farther in) at 12 o'clock; and 1 "tip" contact (all the way in) also at 3 o'clock.

The one plaguing my Late 2006 MacBook is the tip contact. Tugging on it with a bent-tipped safety pin while watching through a magnifying glass works, but only until the next time I unplug the headphones, and so is too impractical. Jostling it with things like air, suction, Q-Tips, toothpicks, ballpoint pen inserts works for some, but not for me. What works for me 100% of the time is inserting a 1/8" metal rod all the way and then dragging it out while applying moderate pressure in the 9 o'clock direction (towards the MagSafe connector). There is no problem using metal, even powered on, because headphone circuitry supplies no power and is protected against short circuits and static electricity. Just be gentle.

The shank end of a 1/8" drill bit works well, and burying the business end in a bottle cork prevents it from cutting you (it is sharp). But I settled on a piece of nail, snipped down to an inch and filed slightly rounded. As a bonus, it fits into the little plastic clip on the MagSafe cable so it is always handy.

Ken W's answer worked perfectly for me!

I inserted an allen key (that L-shaped tool thingy) into the jack and pulled it out slowly, while gently pushing on the 9-o'clock wall of the jack. The internal speakers immediately started working again.

por

I used a wood skewer (like you would for food) and followed the process of sticking it in and dragging the end against each 3, 6, 9, 12 direction. Got to the 6 o'clock position and the sound started working.

Great fix. Thank you Ken!

por

I know this thread is old but this worked! Plus feeling the drag move from the 9 o'clock position to the 6 o'clock position, I opened up the Sound pref pane to see it switching back and forth from optical to headphone and then voila!! Thank you Thank you Thank you!!!

This seems to be a fairly common problem. There is another thread about it here.

Put a screwdriver into the jack... you will feel a little piece of metal. Try to open that piece with your MacBook turned on, music on... and you will hear the sound when the piece of metal has in the correct place.

IT'S VERY EASY. I made that in less of a minute.

Sry for my english, i hope can help. Cheers!

Toothpick trick did not work for me, or anything similar. So, I took it apart to get a look at the logic bord. I reverse-engineered the connections I could access from the bottom of the PCB under the audio jack. While doing so, I found that you can jump two connections (one is sleeve ground and the other I believe is a connection from the switch inside the jack. After doing so, the headphone jack will not work as an audio output for either analog or optical, but the internal speakers will work fine. This is b/c the switch is basically bypassed, the macbook will never know whether there is a headphone plugged in to the jack or not. This fix is fine for me, especially since I had no other option b/c I'm out of warranty and I'm not spending $400 on a new logic board haha.

BTW, I'm a Ph.D. Computer Engineering student, I didn't just do this all willy-nilly out of the blue, haha. You do need a decent sodlering iron to do this and you must make sure you have a very small gauge wire (insulated). This fix can always be undone... if you need to for some reason. Below is an imgur link to a couple photos I took of the area and connections to jump.

NOTE: This is one a late 2008, a1278 MacBook unibody. The macbook pros may be slightly different, but you can figure it out with a connectivity meter and some fiddling maybe. :) They also could be exactly the same, I don't know.

The only things left to consider before Apple repair are USB audio and Bluetooth audio. I got a Syba "usb audio card", which is a little dongle that goes in the USB port and supplies headphone & microphone jacks, off Amazon for $8 shipped, and it's been great. Well, except it is a bit wide and blocks the adjacent port, so I also got a 6-inch usb cable off eBay for $4 shipped. Probably for more $$ you could get a Bluetooth audio reciever or headset, and ditch the connection entirely. Good luck.

Awesome (temporary) solution

Go to System Preferences-Sound- Outpot- look down Use audio port for

Change audio Outpot to audio input

So this will let the computer use its internal speakers for all outputs

I used a toothpick and worked!! THANKS EVERYONE, have to finish a video tonight and was desperate. I had to push it a bit harder towards the end of the jack, and the sound went out after I used a pair of JVC earbuds. Will stick to the Apple ones from now on. Cheers!

Apple told me I needed to replace the logic board. Repair quote was $822 dollars... I fidgeted around with a toothpick as some youtubers recommended, after several failed attempts the light is gone, my speakers play music and I'm $822 richer. Really disappointed with apple on this one.

The only thing that worked for me was to open the macbook, open the actual jack with a wirecutter. We can then clearly see the mechanism, and I just had to poke it with a toothpick.

Has been working like a charm for a few months now.

I downloaded a video off youtube a while ago and couldn't find it, so I just uploaded it there:

have to say a couple of old fashion blows (caution with saliva though) and wiggling the headphone cable jack in and out of the input hole sounded primitive but it worked!

I simply just pushed it in and out rapidly till the red light disappeared and sound came on!

Amazingly advanced mode of repair but worked!
