No sound, red light emitted from headphone jack

So I really have no idea how to get my sound back. I simply pulled my headphones out of the back of my Mac and I lost sound from the speakers in the computer. When I hit the adjust volume buttons on the keyboard, a circle-with-a-line-through-it symbol shows up underneath, and I hear nothing. When I look at the port where my headphones plug in, a red light is shining out of it. I've already checked sound options in system preferences. Did I break my sound by simply pulling my headphones out?? Help!

Had same thing happen a couple times and fixed it by just plugging headphones in and unplugging a couple times.
Don't know for a fact but I think the audio output thinks it has a digital optical device connected (Hence the red light). That would explain why you are getting no sound from speakers.
Next step would be to call Apple.

  • Red light emitting from headphone out (spdif /digital out)

    hey guys,
    i have a red light emitting from my headphone out. I can plug-in the headphone but when i want to hear the built in output (comp speaker) nothing comes out.
    i tried to swtich this option, doesnt give me the option, anyone know how to make this red light go away?

    The red light is the data signal that is transmitted if you plug in an Optical Audio device such as surround sound speakers. I had the same problem for a short while with my 17' MBP. Sound was working fine from my built in speakers but I plugged in some earphones to listen to something that I did not want the rest of the office to hear and after pulling the hearphones out, the optical signal (red light) was being transmitted. The switch Cessna is referring to is the switch that is triggered inside the port that tells OSX that earphones/optical audio device is plugged in and to shut down power to the built in speakers. When the device is un-plugged from that port, the switch should get triggered again and power up the built in speakers and disable the optical light signal. Perhaps there is the slightest defect on the earphones you are plugging in that are preventing it from triggering the switch when the earphones are un-plugged.
    Try a different sent of earphones to maybe trigger the switch if you are uncomfortable with the paper clip solution.

  • No sound on Boot Camp (Windows 8) red light in the headphone jack ?

    I have a MacBook Pro 9.2 (i7 3rd gen, HD4000, 750GB, 8GB) and i install Windows 8 Pro 64 bit. I have a issue with my headphone jack only when i use BootCamp i have the latest driver for it (download from bootcamp application OSX). I see that inside of the headphone jack there is a red light i think that it is the optical out of it. I try to reinstall the driver no succes. Now i need help to fix it

    The red light means you have jammed the digital audio jack by inserting an analog plug too far. It is not a BootCamp issie--can happen to people without BootCamp. Here is the reason for the problem I posted in another thread:
    Background, or "why this happens": the audio-out port on a modern Mac is digital and is held to high dimensional standards. Most headphones have an analog plug not made to such standards. The specific issue is the the "tip-to-stop shoulder" distance on many analog plugs is just a bit longer than on a digital one and jams the "mute" contact inside the port in the muted position. <deleted>'s advice to insert a plug and gently wiggle it in the horizontal plane is exactly on target unless you are under warranty, which would still necessitate a trip to an Apple store for service.
    The best action is prevention. When connecting headphones (or external speakers), put on the headphones and have an audio track running BEFORE you insert the plug. Insert the plug slowly, listening for sound on both channels and, when you hear it, STOP INSERTING.
    Bottom line is you do NOT want to insert any random plug "to the hilt" until you know it is dimensioned to fit a digital port.
    My MacBook Pro has the same jack. I have a pair of decent-quality, name-brand headphones and their plug is not to spec. This picture shows their plug in the port at a position that delivers proper sound and does not let the plug fall out:
    Note that the shoulder is about 1/16-inch from contacting the computer case. It is secure in this position.
    Every plug is different. I have a pair of El Cheapo external speakers I picked up for US$2 at a yard sale and their plug fits perfectly on my Macs with a digital audio port. Go figure!

  • No sound on my mac book and a red light in the headphone jack

    as in the title,
    The sound controls dont work and I have a constant red light out of the earphone jack, with the earphones in all is okay but without ....silence

    The red light is the digital in light, that is how it reads the headphone jack. The reason the sound doesn't work is because a switch to turn the speakers back on is stuck (note that if you boot the computer, you will hear the startup tone).
    There are several ways to fix this...
    Some have found that putting the headphone plug in and out several times (maybe twisting it a little) will work.
    Others have used a toothpick to adjust the switch (I don't advise this because the toothpick may break).
    Instead of a toothpick, many have used a paperclip (probably best to use an insulated one). I couldn't get this to work, but I would suggest straightening, folding in half, then twisting the paperclip and moving it around in the port.
    You can also use a sewing pen/needle.
    I have seen all of these methods online, but they didn't work for me. I took a que from this instrucable and cleaned my jack with a dry q-tip. I then cut off most of the end and turned it around inside the port. This worked, but after I put the headphones back in the same problem came up, I just did the same procedure again and it worked again (even after I plugged the headphones back in and took them out).
    PS: I woud suggest putting some q-tips and possibly some scissors in your MacBook bag in case the problem arises on the move.

  • Is it dangerous to look at the red light in the headphone jack?

    I recently purchased an early 2009 model white MacBook. Today I was installing Windows on it and I noticed a red light coming out of the headphone jack. I thought there must be an LED in there to help you locate it in the dark. I was curious about it so I crouched down next to the computer and looked inside the jack to see what the deal was.
    At the time I didn't know that there is such a thing as an optical audio jack. Obviously I now know that's what the red light was all about. Now I'm wondering if looking at that light could have injured my eyes. Is it a laser, an LED, or something else? Does anyone know how dangerous it is to look at that light? I looked directly at it from close range for perhaps 3-10 seconds, with eyeglasses on. I don't remember it seeming uncomfortable to look at.

    Thank you both for your replies.

    To the best of my knowledge, that light shouldn't be on when the port is empty.
    Yes, my understanding is that that light should only ever come on when there is a Toslink mini-plug adapter inserted into it (or at least a regular 3.5mm analog plug). However, like you said, I've seen a number of posts on the internet about that switch that turns on the digital output (red light) getting stuck in the on position (even without having plugged in a Toslink adapter). My understanding is that in my case the light came on because I was in the process of installing Windows and the driver for the audio hardware hadn't been installed yet.

    As far as harmful rays, I doubt that it would be harmful because I've read about this audio problem before but never with a cornea damage attached to it.
    I did look inside the jack directly at the light. I think it might be the retina that would be at risk if anything, but in any case, I sure hope nothing was damaged.

    The power for the lasers used for digital audio is very low.
    Is it a laser?

    Especially if you didn't find it uncomfortably bright.
    I don't recall having a reaction that it was uncomfortably bright and then having to force myself to look at it. If it had seemed uncomfortable I don't think I would have continued to look at it.
    I don't think I actually became concerned about it until I found out that the light is for digital audio output and wondered if it is a laser. Not that I recommend looking right at a bright LED either. But I wasn't expecting a bright LED either (let alone a laser) -- like I said, my first thought was that there must be an LED inside to make the jack easy to locate in the dark (I was in a darkened room at the time.

    If you've ever, even very briefly, had a low power laser pointer hit your eye, you'd realize it is super bright.
    Fortunately I haven't, but someone who did have a laser pointer aimed at their eye told me they noticed it when they felt a burning sensation on their eye.

    Any damage would almost always be nearly immediate. If you haven't had a problem, you're fine.
    Do you think any damage would be readily apparent right away, in the form of pronounced discomfort or noticeable vision problem?

  • Why is there a red light in my headphone jack

    The speakers arent working and this light is on inside the jack

    Open your Utilities folder and launch Audio MIDI Setup. Something there may be conflicting with your sound output. Unfortunately I do not have any MIDI devices so you will have to muddle through to find out what it is. Try selecting "built in speakers" on the left, or "configure speakers" on the lower right.
    This is what mine looks like:

  • Audio muted/disabled- red light coming out of jack????

    what the heck? anyone know what's going on here? red light in my headphone jack and volume control non-operational. reset the PRAM to get speakers working for a moment before problem returned. works fine when headphones in, but not without.
    and the red light shining out... what IS that?

    Hey all-
    I've worked on laptops before and didn't feel comfortable sticking a metal clip into it. I did snap the end off a Q-tip and wiggled the cardboard ever so gingerly and it went off. BUT later in the week the same problem occurred. I've got an appointment with Apple tomorrow and will keep you up to date on the "official word" with this problem. I'm still in the year warranty period (refurbished pruchased, year up in November) so they should replace anything that is failing this soon in the game.
    Have a co-worker that just had a new MBP's video fail after less than a month of use---Apple replaced the whole machine, but only because it was in the first 30 days of purchase. Doubt they'll make me the same kind of offer. Still sorta miffed to have problems with my newest machine. Never had to get AppleCare, but think I'll have to with this guy... hope it's not IceBook Logic board blues for these first Intel offerings.

  • Redlight from headphone jack not work (Y410p)

    Hello hye  ,Sorry ,  Red light at my headphone jack gone when i format the laptop.

    Welcome to the Lenovo Community !
    I am assuming that you did a One Key Recovery and restored your operating system to a like new condition ? 
    The red light should be OFF when everything is working properly on the your model.  If you did the One Key Recovery then the restoration corrected a driver problem with the audio that was causing the red light.

  • Help! red light from headphone jack and strange sound issues!

    Help! I use my baby for listening to music and watching DVDs almost constantly when I'm working, and just the other day it started doing something really odd whenever I start doing something that involves sound!
    If I'm listening to a song, watching a DVD, playing a game, whatever, as long as it involves sound it does this. What happens is, it'll be fine for up to a minute, and then it starts making this staticky skipping noise and losing the tracking on whatever it is I'm doing (game, song, DVD, etc.). This happens whether I've got headphones or speakers plugged in, or I'm using the laptop speakers. Also, a red light flashes from INSIDE the headphone jack with every staticky noise.
    Everything else works fine. The problem doesn't appear as long as I'm not doing anything using sound, and it goes away about a minute after I stop using sound when it appears. It just started doing this yesterday, which was an entirely uneventful day and no different from normal. I traveled, but the laptop stayed in its case the whole time and didn't get dropped or jostled or anything.
    I depend on my music to keep me sane! I can use my iPod for now, but I've got finals coming up and I need to use music while I study! HELP!

    if the red light is flashing at the output, it means that the computer is trying to output a digital optical signal.. which would explain why your audio is cutting in and out, cos it's flipping randomly between digital out and built in speaker, which means the speaker is being intermittently muted.
    the reason for this is that the sensor in your audio output port is dodgy. this sensor is supposed to detect when you have a digital optical cable connected, and yours seems to just be going a bit nuts. fraid the only way to get it properly sorted is to take it in for a service.

  • Red light from headphone jack--- no speaker volume

    I am sure that I have done something wrong
    but I no longer have any external sound or control of sound for that matter
    and there is often a red light shooting from my headphone jack.
    what must I do to regain control of my sounds.
    thanks

    The red light from your headphone jack is probably from the 'optical digital output'.
    I don't know that model of PB but does enabling the digital out turn the headphone out off? Check in the sound control panel.

  • HT2494 the sound won't work on my Macbook pro  the headphone port actually has a red light coming from it

    Can not get sound on my Computer.  The headphone port actually has a red light coming from it.  Help

    Insert a headphone jack and remove it and see if the light goes out. The red light indicates the switch didn't switch from head phone to your Mac's speakers. Some folks have actually used a match stick to undo the switch.

  • No Sound From Headphone Jack, Only Internal Speakers working in Macbook Pro A1278

    Hello, the internal speakers of Macbook Pro A1278 OSX 10.7.5 are working perfectly, but no sound from headphones or external speakers when plugged in. Headphones/speakers recognized when plugged in, shown by System Preferences/Sound, and since the sound stops from internal speakers when headphones/speakers are plugged in. No red light seen coming from headphone jack, as I read in other posts. The problem began after a cable was connected between computer and stereo system. Maybe overloaded the sound card and burned out a connection? Wondering if you think that the sound card needs to be replaced or is there another solution possible? Thank you.

    Hello JohnBoarkman,
    Welcome to the Apple Support Communities!
    I understand that you hear no sound from your accessory when you connect to your headphone jack. My first troubleshooting suggestion for this situation would be resetting the NVRAM on your Mac. Please use the instructions in the attached article to complete this process and let me know if the issue continues.

  • Red light coming from the headphone port

    does anybody know why there is a red light coming from the headphone port.
    This is after i reformatted 
    Thanks
    Moderator note; subject edited for relevancy

    This is perfectly normal. You can run an optical digital out this way. You need a mini-toslink adapter like this:
    http://en.wikipedia.org/wiki/Mini-TOSLINK
    Then you can set the digital out as default (instead of Speakers) to run audio to a surround sound reciever via optical fiber.

  • Sound coming from headphone jack becomes heavily distorted at the slightest movement of the headphone cable.

    I use headphones almost exclusively of my Macbook Pro (Early 2011, way out of warranty) so this has really been annoying me. For about 1-2 weeks now whenever the wire from the headphones I have plugged in to the jack moves, even slightly, the sound coming from the left side disappears almost entirely while the sound from the right side becomes quiet and filled with static. Strangely, it doesn't appear to happen with everything that I'm doing on my computer. For example when playing games the sound seems to work just fine for the most part, but playing music or watching Netflix causes issues whenever the cord moves, which is really annoying.
    To get it to stop, I have to move wiggle the plug around in the jack and slowly move the cord into a place where it will not be affected by movement very easily. I read that some people have been able to get around this by buying an external sound card and using the headphone jack on there, but I'd rather not do that if possible as there isn't really anywhere that I can put it without most likely picking up some interference. Plus I only have two USB ports, so I have to use a powered USB hub thats about 2-3 feet away from my computer for most things. Anyone know if this is a viable solution or how much it would cost to fix at the Apple Store?

    Also, I have tried restarting my computer, messing with the audio settings, and various other settings that I thought might help.

  • Red light coming from my audio output, speakers not working

    I read somewhere about wiggling a toothpick around in there, but that didn't work, any other ideas.
    This happened after I had a 1/4 to 1/8 converter plugged in there to use a little mini amp.
    I've lost the use of speakers.
    headphones work fine
    I think the optical input is still reading as if something is plugged in. Not sure if there's something in my system I need to switch, or if I need to take it in, have the jack opened up and replaced

    Just to rule out the obvious make sure your mute switch (F3) is not on. If your 'switch is stuck' you would see a red light coming from the headphone port.
    Double check your Sys Prefs - Sound settings ...if things still are not working you might try a SMC reset followed by a Pram reset that would restore your orig. settings.
