Headphone jack has red light

The output (headphone) jack on my MacBook has a red light in it and I can't produce any sound from my built in speakers. Also, I cannot control the volume level; it shows the volume maxed out, but all the slider controls are greyed out and, using the volume buttons, shows a crossed out circle instead of the speaker icon. If I have headphones or speakers hooked up everything works fine, but if not then I can't use sound. Any ideas?

There is a micro switch that can get stuck....use your headphone plug and try plugging and unplugging it several times.....there have been numerous threads about the problem...you might also try using 'Search Discussions'...enter 'Red Light'

  • Headphone jack displaying red light

    The headphone jack on my macbook is displaying a red light, and the built in speakers will not play. However, whenever I plug in speakers, the sound works. What is going on? Is something jammed, or can this be fixed with the push of a button?

    It means your digital audio out has switched on. You can insert a plastic toothpick in the hole and try and switch it off. The switch should be at the 3 o'clock position and go towards the 6 o'clock position. Some people also have had luck inserting their headphone jack and pulling out a few times. Another recent report was that inserting the headphone jack and turning it in the hole helped.
    If your not successful or uncomfortable doing this you need to contact Apple about service.

  • Headphone Jack Glowing Red, Internal Speakers Not Working...

    Hey, I have a 2.0GHz White MacBook (almost a week old), and I just recently came across this problem (this morning, actually). I usually have my MacBook connected to some external speakers through the headphone jack, the internal speakers are pretty terrible. Anyway, last night I left the computer on playing music as I fell asleep, this morning I woke up and the computer must have some how come unplugged from the AC power, as it was dead. I plugged it back in and everything was fine (I mean, it had to charge up, and the battery 'health' in iStat Pro was down to 93%, also not sure what this means... But everything else was fine). Then, I unplugged my external speakers and the jack was glowing red, I believe there's an LED inside. The internal speakers would then not work.
    I did a quick Google search and discovered that this problem had been experienced on MacBook Pros. Someone recommended plugging in a set of headphones, I did so and then unplugged them and the internal speakers worked for a moment. I plugged in the external speakers again, and they worked (and work) fine. The problem is with the internals, they don't work, and plugging in my headphones again has not solved the problem, and the light is still on when the jack is not occupied.
    Any ideas?
    [edit] As of this writing, they are currently working, after plugging in the headphones again and unplugging them, however, the light still blinks when I do this, and there is a bit of a hesitation between the headphone being unplugged and the internal speakers kicking in... (longer than normal, I know there was always a slight delay, but this is a few seconds of blinking light and no sound).

    you can fix this by "cleaning" the audio jack. the computer thinks that a digital output is connected. if you go to sound under system preferences, and it says digital output rather than internal speakers, then this is the problem.
    I used a tightly rolled up piece of toilet paper to clean the jack. I twisted it up, stuck it in the jack, and then moved it around for a while. the red light went off and my internal speakers started working. someone else used a toothpick.
    also, before i fixed this, i couldn't turn the volume up or down (unless i was using headphones) and the volume level screen that shows up on the screen had a circle with a line thru it...like the no smoking signs, but small and just under the volume bars.

  • Audio jack showing red light indicator

    audio jack was showing red light when i was installing windows first time via boot camp ... !

    Try System Preferences>Flash>Advanced tab>Delete All... 
    My wife's 2011 mbp had the same problem:
    no sound from speakers,
    sound okay in headphones,
    red light on in jack,
    slow computer.
    She plays MANY different FLASH online games in Firefox. I searched everywhere and found the same advice as you all did ref toothpick in headphone jack, etc. Nothing worked.
    Today, I googled "firefox" "problem" and "sound". I found "Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems". I stopped reading at this point and decided to check out the status of her Flash settings. I opened System Preferences > Flash and explored the different tabs and options on  my mbp compared to hers and noticed a LOT more "websites" in her Storage and Camera & Mic tabs. I went to her Advanced tab and selected Delete All... . It took over a minute to clear all her "websites". I did a reboot and was shocked, surprised, relieved that her mbp speakers were spewing sounds again! Problem solved! Her computer is now faster as well.
    Short story:
    System Preferences>Flash>Advanced tab>Delete All...
    Hope it works for you, too.

  • Ok so my iPod headphone jack has been steretch out

    My iPod touch 3rd gen the headphone port has been expanded so that it will not play music throw both sides of the headphones. What can I do to make the head phone port smaller to make it work right or do I need to buy a new iPod?

  • Headphone Jack has broken - dock adaptor 3.5mm female?

    Recently, my 3.5mm headphone jack for my 5.5video 30gb ipod has broken, it only played out of the left channel and is really distorted, is there an adaptor to get the dock connector to connect to my headphones - such as http://www.amazon.com/Cables-Go-35508-Connector-3-5mm/dp/B000J022G6 but to female. It's also important to keep good sound quality to me, thanks.

    There are online places that can replace the headphone jack for you and many have one day turn around service.

  • Ipod touch's headphone jack has gone faulty

    Hey,
    this is the second time this has happened and the second ipod its happened too, this happened last time and they replaced it but this time my warranty is no longer in date so i havent got a clue what to do, does this mean i will have to pay or will me out of date warranty cover it as its a hardware fault not a user fault.
    Thanks.
    SOphia.

    Try inserting and removing the headphone plug at a dozen or so times.
    Try the standard fixes to rule out a software problem:
    - Reset. Nothing is lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup
    - Restore to factory defaults/new iPod
    Last, make an appointment at the Genius Br oif an Apple store. It appears that the headphone jack is bad.

  • My internal speaker on mac book pro works through external devices (e.g headphones) and a red light appears on my audio line port what should i do?

    i used macbook pro  2009 OS X 10.9.5 yosemite and  i got troubled on my internal speaker  and it only works through external devices what should i do pls help?

    This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum.
    Please move the MacBook Pro forum. Thanks
    Also if you mean by external is via the headphone jack then try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so. There is a little switch in the headphone jack that disconnects the speaker when the headphone jack is inserted.

  • 3.5-mm stereo headphone jack has broken. I want money, Apple.

    I went to the Apple store today and found out that I have been inflicting irreversible damage to my iPod by wrapping the earphones around it when I'm not using it. Apple told me that, +while this is a common problem+, they don't replace or repair the earphone socket. When my mom questioned why no one told me that wrapping is harmful, they shrugged and said that +it wasn't a common enough problem to publicize it+. *Furthermore*, this is the *exact* same problem that broke my last iPod. No one even mentioned a '+stressed left ear sensor+' back then. Apple has cost me (old iPod + new iPod prices) +$550+ for _THEIR LACK OF PUBLICITY ON THE SUBJECT_. I've been looking through the iPod touch safety manual and it says absolutely nothing on this problem. I request a *repair* and an _OFFICIAL warning from Apple_ so that other users will not fall victim to this.

    That's why I am frustrated. I didn't know it was harming my iPod. +I didn't even know it was putting stress on the socket+. No one informed me of my error, not even after the first time. Besides, coffee is naturally hot. You expect it to be like that when you order it. The iPod is a portable music-playing device, so it's only natural that someone should capitalize on this by wrapping the headphones around it. I know I'm not the only who does this, so I'm disappointed in Apple for not issuing a warning.
    The coffee comment was referring to a lady that sued McDonalds when she spilled coffee in her lap and got burned. At some point people have to take some personal responsibility and quit blaming someone else for their mistakes. Apple does not state in their warranty every specific thing that can invalidate the warranty. That would be impossible.

If you are concerned with your earphone cables lying around, you could get a set of bluetooth headphones.

  • LED in Headphone Jack glowing red!?

    I recently had my headphones plugged in and when I pulled the plug out of it an LED turned on right inside the actual jack itself.
    Since then I cannot control the volume level of my mac via the keyboard/volume meter on the actual bar. I am able to mute the sound but when the little volume level window shows up in the middle of the screen there is a little "( \ )" picture underneath it.
    I've never seen this happen before, if you know how to fix this issue please post ASAP, thanks.

    Hello and Welcome to Apple Discussions. 
    Unlike the older iMac G4 (Flat Panel) the iMac G5s and iMac Intels have Optical Digital Audio ports inside their standard 3.5mm Audio ports. Unfortunately many of us hear (pun intended) aren't familar with the iMac you have so you'll need to post elsewhere.
    G4 (Flat Panel; 700MHz - 1.25GHz): G5 (1.6 - 2.1GHz):
    The only thing I could suggest is to go Apple Menu > System Preferences... > Sound > ... and check that you aren't set to digital output or something similar....
    kind regards

    Macbook Audio Fix-- No Speakers; Red Light in the Headphone ...

  • Headphone jack light

    occaisionaly a red light comes from my headphone jack and no sound will come from the speakers. the longer i stay on my computer the less the red light comes on and stops whatever it is i'm listening to at the time. i assume it's a setting problem, but i'm computer illiterate and i don't know what to change. i've talked to a few friends with macs about it and they've all never had a problem like this. what should i do to fix it?

    Your Macbook has the ability to do optical audio out, so that is what the red light you are seeing is. Normally, an adapter is used for optical audio, but something must have happened to the headphone jack on your Macbook is it is showing without that adapter. Whenever that light is showing, you won't be able to use the headphone jack when that light is showing because it is not sending out that type of audio signal. I would suggest getting it fixed by either calling AppleCare, or making an appointment at the Genius Bar at your local Apple Store.
