View Full Version : MacBook Pro optical out won't turn off

Somehow the optical digital audio on my MacBook Pro has turned itself on, and I can't turn it off. It's pretty annoying because it has disabled the speakers. When I stick headphones in, they work just fine (they're regular, analog headphones), but as soon as I take them out the red light inside the port turns back on, and the analog audio opition disappears from the sound preference pane. All that appears in preferences is Digital Out.

Has anyone else had this problem? How do I get my speakers working again?

Thanks.

Trash the file ~/Library/Preferences/com.apple.audio.AudioMIDISetup.plist

Then restart and see if that helps.

Actually, it's a hardware problem with the combined analog/digital optical port. I found a thread on the Apple Discussion site (http://discussions.apple.com/thread.jspa?messageID=3255575 ) that discusses it. Apparently, one solution is to stick a toothpick in the port and fiddle around until some sensor latch releases. Scary. Good thing I'm still covered under Applecare - this laptop's going in for some servicing!

I experienced this very same problem. The toothpick working in about 10 seconds. I think the sensor is at the base (bottom of the minijack) hole.

I was surprised it worked so easily. I hope this isn't going to be a continuing problem. It is good to have my speakers back.

This is caused by being hard on the interface, bad plug inserted, bending plug, or just being forceful. Ive had my left I/O board replaced by apple twice because of this issue.

No, it's not. It's caused by shoddy Apple design. Take it to the apple store and they'll replace the audio IO board (with a better design jack and output preamp). That's what happened with me . . .

The toothpick method worked for me. My AppleCare is expired now, so I'm out of luck. Good thing the Random Shut-off issue started happening like two weeks ago...guess I can pay for my own logic board :)

My MBP got this issue today. I must admit that in my case it's probably due to defective hardware: I once pulled the cable accidentally to the side, which could have damaged the latch sensor :(
Luckily the toothpick worked like a charm.
In any case I've attached an image showing how it was before fixing it:

does the audio output still sound hissy after the replacement? i think the hiss alone is reason enough for apple to do a replacement.

had the same problem, and toothpick worked like a charm. hope it doesn't happen again - though if it does, I'll just take it to the retail store before my applecare runs out..

Hi, I used a toothpick and also had results. Although on reinserting audio plugs (headphones, lineout etc) the problem occurs again, resulting in additional toothpickery! Would anyone suggest that this a replaceable reason for apple store? I am still under warranty.

Thanks.

I have a unibody MacBook Pro 13" (Mid-2009) and I am having the same problem. I didn't have a toothpick handy so i used a twisty-tie. Too bad they didn't fix this problem.

Had this same dumb problem. Hasn't been easy to get the headphone lead into and out of the jack for the last 2 yrs and this "Digital Out" on all the time thing occurred recently.

I didn't even know my computer had digital out!

Anyway the toothpick worked very easily.

Thanks

Had the same audio problem...

Symptoms: no audio from internal speakers, pressing volume control buttons displayed a circle with bar thru it, system prefs showed digital output... and original headphones worked fine and controls worked when plugged in..

First thought it may have been software problem or settings adjustment or my addition of third party software as i had recently downloaded and been using Boxee alot lately and maybe something got out of whack.

I read the previous posts and saw the toothpick workaround..

Saw the red light glowing inside the headphone jack... which i learned was the optical digital output.. which i didnt use but im guessing somehow got triggered..Possibly because i was regularly plugging and unplugging a connection to my audio for my Boxee setup..

Since i was at work, no toothpick available... I took a paperclip, wrapped plastic tape around the end (didnt want to put metal inside the sensors inside there) gave a bit of a tape overhang on end of paperclip and bent that portion of the tape so it had a tiny 90 degree crook at the end of the tape...

Wiggling didnt work.. pushing in and out didnt work.. then turned and and made a circle inside the best i could thinking i could reset a sensor.... when i pulled out the paperclip.. saw the red light had gone off... looked at my tape wrapped paperclip.. and low and behold.. dirt/dust was stuck to it...

Everything back to normal.. volume control works.. internal speaker now detected in system prefs etc... all is good in the world :)

I've had this problem for over a year and it sucks. I've tried sticking just about everything in there to no avail. I didn't get Applecare, so I'm out of luck there.

The problem is actually caused by a little switch inside the jack that gets stuck. When you stick in an audio cable, it pushes the switch down. If it's an analog cable, the end is made of metal. If it's optical, the end is made of plastic. If the switch is pressed down, the computer checks to see if the plug inside is metal or plastic based on conductivity. When it gets stuck and nothing is in there, it thinks an optical cable is plugged in since the switch is down but nothing conductive is in there. That's why it works with headphones or external analog speakers.

I might try the tape thing. It's about the only thing I haven't tried and I don't really have $450 to replace the logic board.

I had this problem yesterday after installing Windows 7 on Bootcamp partition (probably coincidence but thought worth mentioning).
However, although I see the red LED light only occasionally in the headphones socket of my MacBook Pro (2008), my volume control is constantly in background and locked in digital out mode. Headphones work normally if I insert them.
I have tried inserting a few objects (toothpick, pen ink holder, matchstick) but to no avail.
My MBP is 1.5 years old and I have no applecare so repair not an option for me.
Any additional tricks anyone can think of?

Thanks

I used a earbud thing, and cut the top of and stuck it in, ull feel it kind of attach to something inside, pull the cotton bud out and the red light flickers, well it did with me, i was happy as larry when i saw it lighting up:) now i can go buy my optical cable, although it only flashed twice? is that what its supposed to do?:confused:

This is total bulls#@t, after spending 4 grand on a macbook pro I shouldn't have to stick fricken toothpicks into it! I've had my mac for about a month now and havent done any forcing or shoving of any kind, so why is this happening?:mad:

ImposterOak,

Thanks for the information asbout the switch, after reading that I felt more comfortable about how to release the switch. A co-worker has had this issue for a long time and I told him I would try and figure it out. Once I realized I had to try and lift up the switch every thing worked great!

What a great place for help!

Who would believe that on a $1699 macbook this worked! I have had nothing but problems with my macbook since the warranty expired! I still love mac, but this answers my question.. Why did the applecare plan go from $69.00 (a year and a half ago) to $299.00. Now I know! :mad::apple::mad:

Simply mind boggling that this works.

Thanks to the guy who recommended a qu-tip instead of a toothpick. I dont have any toothpicks either.

Drove me nuts for the better part of an hour trying to figure out why my built-in speakers disappeared from the preferences menu.

Thank you so much guys.

I used the tooth pick method and it worked wonders.
I still have a couple of years on my apple care, so if it happens again I'll take it into an Apple store.

But for now.... It Works!!

this is what worked for me.

just insert your headphone/earphone plug into the audio-in jack (next to the earphone jack) then remove. the sound comes back and the "prohibit" sign (circle withe the diagonal line) disappears.

This has just started happening to me on my early '09 MBP. Today was probably the 3rd time and I just noticed the digital out light source being on. Mine happens when I plug in a set of external speakers on my desk. Super bummed that I am going to have to be prepared to jam a toothpick into my $1800 laptop. Thanks Apple. :rolleyes:

This is caused by being hard on the interface, bad plug inserted, bending plug, or just being forceful. Ive had my left I/O board replaced by apple twice because of this issue.

Wrong. That is what Apple is probably telling you when you bring it in. I can assure you that I couldn't be more gentle when inserting/removing my ext. audio plug (which is by all means the proper plug). And based on the number of folks experiencing this it is safe to say its either a faulty production run of the jack or just a bad design in-and-of itself.

I might try the tape thing. It's about the only thing I haven't tried and I don't really have $450 to replace the logic board.

Years ago when a $2 jack failed a repair tech would replace the $2 jack.

I know the reason for replacing the entire $450 board is because replacing the jack requires more skill and Apple does not have enough techs who can work at that level. But there must still be some real repair shops around. Swapping out the jack is a 5 minute job and is not total rocket science.

In the late 1970's I was a college student at UCLA and I worked a few hours a week in a lab fixing small computers. (intel 8080 and Z80 based in those days) We had a 'scope and other test gear and did replacements at the component level. I was just an average engineering student, no degree (yet) and the job was not hard. Back then no one would think about tossing out a entire logic board because a $2 part on it was bad. Even today students are happy to work if you offer only $12/hr.

this happened (2-3rd time - though only bothrered me recently as lasted one day)

booked appointment at applestore (yay new 3.5jack )

then after plugging / unplugging ext. hifi jack - it worked again,

so just stick a 3.5 plug in there and should work eventuallly - i noticed the red dig optical out as well.

Something else to try, because this same thing happened to me a few years back on a brand new Mac Book. The problem was caused by me shutting down the computer with the headphones in the jack. Once the computer was off, I had unplugged the headphones. The next time I started up the computer, the red light was on and I had no audio. I had tried inserting the plug several times in hopes of triggering the little switch, but that seemed random and prone to causing more frustration. I decided to work backwards and think of things that might have caused it. Finally stumbled onto this one...while the computer was on, I inserted the headphone jack. I then shut the computer down with the headphones plugged in. Still keeping the headphones plugged in, I powered the computer back on. Once I got to the login screen (just a good spot to know that all of your hardware has probably been initialized), I was able to unplug the headphones and have audio restored. I should also mention that I was able to reproduce the problem and fix it with the same solution several times.

Granted, this would not explain the switch getting stuck due to dirt or grime or it getting bent or jammed due to improper use. That stuff can happen. However, before you go jamming a toothpick (or even a q-tip) into your headphone jack...or simply inserting the jack over and over in hopes that it will magically start working again...give this a shot. It'll take you very little time to try, and if it doesn't work...it's one more thing you can cross off the list before resorting to one of the other methods.

Thought I would share.

Tooth picks, bobby pins and paper clips with tape didn't work for me. After poking several foreign objects in the head phone jack for a week on and off I ended up finding out by accident that a head phone jack plugged in half way also brings back my external speakers. So I took an old pair of Ipod head phones and made the jack as short as possible. I am not crazy about a 1/4" end of the jack hanging out the side of a $2,500 MB Pro but no apple care, so this will suffice for now.

While I couldn't believe what I was reading, I decided to try a cotton swab (wooden stick with cotton top). I inserted it once, twisted, pulled out and found the cotton filled with black sooty looking dirt. A second try instantly changed my toolbar icon from opaque to the usable, adjustable tool that I used to have. What a fix!!!

Whoever identified this problem as a hardware problem and thought of the toothpick fix is a genius.

Thanks

No matter how good Apple as a company is sometimes their staff know ZILCH. I had this very common problem & let's face it, Apple do read these Forums & they do know of this problem but haven't bothered to fix it nor, more importantly tell their staff what to do. I expect it's a bit embarrassing to tell staff that they should tell customers to stick toothpicks (in my case a de- cottoned cotton bud in A wiggle it around. So much for brilliant apple technology. In any even what the heck is a switch doing inside the hole in the first place.
i took my macbook into an apple store & the guy was as useful as a chocolate tea pot. He said he'd never heard of this issue DUH! He said I may need a new board! Thank God for the internet & forums like this. Some people have being saying it's a software issue & a certain file needs to be deleted- (~/Library/Preferences/com.apple.audio.AudioMIDISetup.plist)

I'm not a geek but another posting said "In fact you need to go to Home/Library/Preferences and delete the file" I suppose this is the same. As I said I'm not a computer wizz so I do wish that people would assume that we know NOTHING . I couldn't find this file! Easy full steps would be much appreciated. Pasting both into Finder produced nothing but obviously I may not have been doing something wrong.

If you can solve the problem with a toothpick or cotton bud then it cannot be either a software or board problem. I know it's scaring stabbing stuff into your Mac but this just saved me 200 +.

LESSON- Don't believe what Apple tell you. Take everything with a pinch of salt!

I tried the toothpick fix and no matter how many times I poked and prodded, nothing happened. I bent the end of it some and tried that - still nothing. But then I broke off the bent end, leaving a slightly rough flat end. Tried that a few times, heard a flash of audio, then nothing, but on the third attempt it worked like a charm.

It is true that sometime you will get a tech or a specialist at the Apple store that is new or thinks he/she knows the world, but for the most part they do want to help. All the techs I was leading were very good at listening and empathizing ... they also read through these forums and others to stay up on what is going on. No one can really know it all but those that dont need to understand that they dont and humble themselves to finding an answer.
With that said, Apple cannot give you direction outside of a very strict set of rules... what is customer installable or customer fixable. Telling a customer to stick anything other than whats made to go in said hole would bring on a whole other set of issues and potential lawsuits. Thanks to the Lawyers...
They really do have to be very careful about advising customers. Those that dont follow that, get written up and then fired if it keeps happening.

Problem caused by the stwitch getting stuck. This is a mixture of grease and dust.

Best fix is to get as much dust out using a cotton bud dry. Then spray a little WD40 on to the end of the bud (with the computer off) and repreat the process. This wil help to deal with some of the grease. Next spray a little WD40 directly into the hole and leave for a minute. Clean with a new cotton bud. This will have dealt with most of the dirt but any grease in the switch itself is still going to cause sticking.
Spray into the hole again and insert and retract a headphone ack about 30 times. You can also try spraying a little WD40 on the end of the jack and keep repeating doing it about 50 times. This will allow some of the il to work its way into the swtich mechanism, freeing it up.
Leave the computer for about 10 minutes to allow the WD40 to evaporate. Then turn the machine on. you should find the device working properly.

It is a good idea to spray some WD40 on an old headphone jack and to repeat the process every couple of months. The Apple design is quite bad. if you already have sticking switches it will keep recurring.

WD40 will not hurt your electronics but it is a good idea to use it sparingly and to avoid getting it on the casing as much as possible because it can feel a bit oily. Good luck.........:apple:

It worked for me. Do at your own risk.

I had almost the opposite problem with my five-year-old Macbook. The light coming out of the optical out apparently had become too faint to even be recognized by my external DAC. Fortunately, the solution presented in this thread worked just as well for my problem, except I additionally used a bit of Isopropyl alcohol, which made it much easier to clean out the port. There was quite a bit of dirt stuck in it... :p

My audio jack has grown progressively worse.

At first I could blow into the port to disable the digital audio mode (people looked oddly at me for some reason). Then the toothpick worked fine for awhile. When that stopped working I tried using a speaker pin to fix it, but that seldom works for me.

Today I had to combine my methods. I used a straw-like coffee stir and inserted it into the audio jack. That did not work. So I blew into the coffee stir and the digital audio mode immediately turned off.

Not sure what I'll need to do if the port becomes still more difficult . . .

Alright...i've been a victim to the same red light phenomenon on a MBP bought in mid 2009...
Internal speaker not working, red light beaming out of the audio port, ext. speaker working fabulously... following up on the forums and the net, i too went the "prodding stuff into your macbook" way...

so i took a safety-pin, inserted it into the audio port,.. a small ball-like something was protruding out of the side of the audio port at around 3 'o clock. I found that upon touching this round object at a particular angle, the light disappeared, and the sound returned. so i kept on prodding at it...till the light finally disappeared and the sound returned to my sheer happiness!

But the next instant, i plugged in my ext.speakers and they weren't working! With the ext. speakers plugged in, the volume controls are locked and greyed out and the sound preferences display 'digital-out' as the output....and with the ext. speakers not plugged in, everything works normally!

i'm miffed at this whole thing... what do i do?...my apple care's expired as well!

I was reading some other threads on this topic, and it seems like this was caused, in my case, by using iPhone 4S headphones. I think the plug is very slightly longer than a normal 1/8" plug.

After inserting various objects of different sizes into the hole, and trying different motions without finding the right spot, I finally stuck the iPhone connector back in, and pulled it out slowly and gently. This made the computer happy again, and we're getting along better than ever. :cool:

Another forum suggested another fix which worked for me (and I did not have the red light). Turn off laptop. When you're turning it back on, as soon as the gray screen appears hit OPT+COMMAND+P+R at the same time for about 20 seconds. Logged in & it was working. Went to system preferences/sound/output & Internal Speakers magically re-appeared.

I just started having the same problem 30 mins ago, and immediately came here to find an answer. I was disappointed to see post after post of people getting hardware components replaced, and even people sticking toothpicks inside their computers. Finally I came across one guy who stuck a paperclip with tape on it into the headphone jack and not only did it fix the problem, but some dust/dirt was stuck to it. So I tried the easiest solution and it worked.

BLOW INTO THE HEADPHONE JACK

It immediately worked

I verified this was a hardware problem by booting off an external drive; still no sound.

And for those of you who can't get it to work no matter what, get a pair of bluetooth speakers. The Creative D100's are only about $60; sound is much better anyway...

Thats not the point... And it has other effects as well, such as I cant stream to my apple TV because of this. Dont know why that would be, but I cant.

And to whoever said its because of abuse to the plug, NO ITS NOT. I have NEVER used my headphone jack once, and I went today and bought the adapter to try optical for the first time ever and now its stuck on optical. FIRST time ever... explain how that is caused from abuse and not and apple flaw and ill suck your you know what.... and im NOT gonna come suck you off lolol.

Some time ago I had the same problem on my Mac Book. I had another Macbook with a broken main board, so I decided to wrack the connector. This showed clearly how the switch inside the connector works. After that I opened my working mac and the connector and cleaned it. Follow the instruction here: http://www.ifixit.com/Guide/Repair/MacBook-Core-Duo-PRAM-Battery/297/1, but not all the way! Don't remove the main board, or the cpu-cooler. Go so far that you can reach the metal strip on top of the connectors. This strip should be bend so that the connector is reachable. See first photo.The audio connector is inside a metal box. That box is for radio wave interference and for strength. So you can just wrack it open with pincers and a screw driver. Just watch out you don't drop any metal parts on the main board! When the box is removed, remove the plastic top. Now it is quite simple to clean the switch. See photo 2, the arrow is pointing to the switch. Don't be confused by the photo, you shouldn't remove the connector from the main board! On the left you see the wracked metal box. I used compressed air to clean the switch. When done (just connect the keyboard and start your mac to test), put back the plastic top, put some tape on it to keep it together and if you don't use brute force injecting a connector, you will be fine...
Hope this helps!

Used the toothpick in a mid 2009 17" MBP. The red light disappeared after a few seconds and the internal speakers option reappeared.

Late 2009 iMac here. Funny thing is I NEVER use the headphone jack. And when I mean never, I mean NEVER.

Came across the problem installing Win7 on bootcamp. No sound. Fiddled with drivers and this and that for a couple hours even though the software was reporting that everything is good. Looking into the port I see the red light.

Sadly no amount of siwtching fixed anything. I had an extended warranty but it expired around december. Super bummed... not something worth $450 (based on what people are saying here) to fix when the computer is worth something like $1000 at this point in the game.

Any suggestions? Would a third party repair shop be able to handle it? Hell, I have some soldering knowledge, though I have never taken apart one of these machines and the cost of the specilized tools alone might just get a serviceman paid to fix it for me. Or am I dreaming?

Any help is appreciated.

If it's *only* happening in Window then it's a Windows driver issue, not a hardware problem.

No... it's not a driver thing. That stupid red light is on. I have read of people not noticing the problem until booting into windows. Not sure why, but either way, I am certain it isn't a drivers issue.

It's not a "drivers" issue.

I believe there is a small -mechanical switch- built into the port, that activates/DEactivates the optical portion of the output when the optical connector is inserted/removed.

That switch can become "stuck", and the result is that the MacBook seems to be "locked" in "optical mode" (which it -is-, because the switch won't DEactivate). As noted above, you can ascertain when the MacBook is in "digital" mode because the red light (optical beam) will always be on.

The trick is to use something to lightly touch the switch so that it "snaps back" to the DEactivated position, in which case a normal (analog) stereo input plug will again work.

No... ...That stupid red light is on....

Just a slight correction. Seeing the red LED is not an indication that the S/PDIF is active. Almost always the optical LED's are lit in a powered on mode (at least in AVR's, Windows PC, CD's players, iMac, DVD players, Mac Pro,....) even when not passing audio.

So even if the drivers are working correctly and no audio is sent to the S/PDIF the optical S/PDIF will still be lit.

As I said - if you read my post again, if it is *only* happening in Windows, then it *is* a Windows driver issue. Not having the Windows driver installed can, on some models, force the audio card into digital mode. In this case, no amount of flicking it with a tooth pick will solve it.

If it is happening on Windows **AND** OS X, then it is the little switch getting stuck. It is a mechanical switch which detects the presence of metal objects. Metal object = headphone mode, non-metal object = optical, none = internal.

Ultimately - boot to OS X, and if you have sound, the hardware is fine.

Well, not sure what to do about drivers then. This WAS working at one point. I have installed on many a machine. Never have I spend this much time on drivers alone lol.

This is the only thing I have found to work but it works EVERY time.

1) Open Computer
2) Go to AUDIO MIDI Setup
3) At the very bottom left corner hit the "+" sign.
4) "create multi-output device"
5) In the settings for that device "check" the box "built-in output"
6) Hold down the "option" key and click the speaker icon at the top in the home bar of your computer and make sure to select "multi-output device".

Now you should get sound back from your computer speakers. But you still might have the grey icon up top and not be able to control the volume. So:

7) Hold down the "option" key and click the speaker icon at the top of your computer screen (on the home bar up top)
8) select "internal speakers"

Now every time you use headphones and then unplug them you will likely have to repeat #6-8.

i couldnt find a tooth pick, so i used a qu-tip without the cotton on it. it worked! anything that saves a trick to the apple store is fine by me :)

I can get the optical sensor to swtich off by bottoming out a paper Q-tip stem, but it only works while I'm holding it position. So I shortened the stem off so it was short enough that the cotton tipped end would hold it in place. Funky. If it take it out, no more internal speakers. Seems I have no choice but to get the board replaced.
