Light in Headphone jack...

I have compared the headphone jack on my wife's 3gs with my new iphone 4 and have noticed that there seens to be a noticable light when I look down into the headphone jack hole. That is to say when the phone in on and the screen is lit. Is this a common thing that others have noticed.. And just the way the phone jack hole is designed? It would make me feel better to know that it is this way on other iphone 4 phones, and that it is not just something I imagined.

I'm on my second iPhone 4 now, and they both have light leaking through the headphone jack! I don't think it's a problem though

  • Macbook 2008 no audio from speakers - can't disable digital audio - red light in headphone jack

    Looking for help with this problem, that seems like a lot of people had in the past and still have, but I see that a couple of discussions on it here have been archived. Too bad, as the problem continues.
    I seem to be having the same problem with my late 2008 white 2.1Ghz Macbook.
    I had used earphones a few times with movies and iTunes, with no problems. Now I've just rebooted to find that I have no audio from internal speakers (the boot up chime works though). Earphones work perfectly.
    There is a constant red light in the earphone jack. The volume icon in the top menu bar is greyed out. In the Sound preference panel, Built-in Speakers are not available as an option for audio out. The only option is Digital Audio. If I connect earphones, then they are available as the only option.
    I have tried all the various methods that people have recommended, to switch off digital audio through the earphone jack: trying to flip the little switch with a toothpick, paper clip, etc., as well as cleaning around inside the jack with a bit of rubbing or cleaning alcohol; also tried inserting and removing the earphones plug several times, while pushing the volume buttons on the keyboard. Nothing works.
    I did get something from inserting/removing the earphone plug, as I seemed to be able to adjust volume from the keyboard, but I never got sound out from the speakers; the volume window seemed to indicate increase/decrease volume as I pressed the keys, but after a few seconds the volume window greyed out again with the No Entry symbol.
    Trying to flip the digital audio switch in the jack occasionally gets the red light to turn off for a couple seconds, but then it comes back on.
    Is there any particular problem with this that can't be solved by the aforementioned methods, that many people have used to solve it in a simple manner? Could my problem be more serious? Is there anything I could do if I opened up the Macbook, e.g., somehow to manually turn off the digital audio switch?
    Any help greatly appreciated.

    Got it fixed with a small flathead screwdriver with a fairly wide blade. Opened iTunes, started playing songs, had red light in headphone jack, as per usual with this problem.
    Put screwdriver in jack, with blade more or less vertical, started moving it around inside of jack in clockwise motion, pressing pretty firmly. Took just a couple of "swirls" around the inside of the jack and then audio finally turned on! Was a bit of a hassle, but finally worked.
    Many thanks to all for their suggestions.
    P.S. re. advice not to use metal object. This was the only way I was finally able to solve the problem (i.e., using the small screwdriver). I didn't see where using a metal object would be a problem, seeing as the headphone plug itself is metal. Anyway, it worked.

  • When on windows xp red light from headphone jack and low sound

    I put windows xp sp3 on my computer about a week ago. There is a red light that comes from the headphones jack that is always on. The sound is only audible at full, it is extremely low. I don't understand this problem. It only happens when Im on windows (T_T I like to play sims). Does anyone have any information, or helpful suggestions about this? Thank you.

    I think this was covered in the update for bootcamp.

  • How do you disable "digital optical output" so the red light in headphone jack goes off and I can use the internal speakers?

    HI,
    I have a red light in my headphone jack and I see "correct responses" listed as "when digital output is enabled speakers are disabled." That's all well and good but doens't really help. HOW do you disable the "digital output," get the red light to turn off and be able to hear through the speakers? What's the SOLUTION to the problem. Sorry, just a bit frustrated. Any help is greatly appreciated.
    Best,
    dpeast12

    Allegedly this can occur if there is a contaminant in the headphone jack that makes the computer believe there is an optical connection there, so it shuts off the internal speakers.
    Try inserting and removing a headphone plug repeatedly. This ought to dislodge the junk, and seems to have fixed the problem for others. Hope it helps!

  • No audio with 64 bit Vista Ultimate, red light in headphone jack

    So I've been searching these forums for the last several hours, trying to find some helpful tidbit of knowledge to help me in this situation.  I have whatever the latest version of bootcamp installed, and just did a full install of Windows Vista Ultimate (64 bit).  With relative ease, I got everything working except for sound.  With the generic driver off the Snow Leopard install disk, it tries to tell me it's working, but there is obviously no sound.  The red light inside the headphone jack stays on all the time, and I have tried all the dumb tricks suggested for that issue too.  I have unsuccessfully manually installed the latest realtek driver (2.28), and even tried both the 32 bit and the 64 bit. The 32 obviously does nothing, but with the 64 it tells me the device won't start, and shows that obnoxious yellow exclaimation point.  Just trying to progress beyond this point so I can hear what I am trying to do in windows.  Please help!

    Same problem here. Daily I plug in speakers at the office, then rely on internal speakers while on the road/at home. I use old analogue speakers that go into the headphone jack.
    I don't think i have any firewire audio out devices, but think i might put my hands on a USB one, so will try a varient of that trick.
    tried the "wiggle the plug" solutions, but no luck.
    I have to say, after something like 20+ years of using apple products (IIC was my first), my instinct here is that this is a software issue. People are getting sound out of a variety of devices (USB, Firewire, headphone plug) and the problem is intermittant but recurring. I don't wonder if it didn't start w/ the last iTunes update (to 4.9)? just a guess there. (although note that when i was fiddling w/ iTunes, the system speed and iTunes slowed way down.
    Apple, please note there are two other related threads on this, one small at

  • 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
    1.67 g4 powerbook hi res   Mac OS X (10.4.6)  

    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.

  • No sound from internal speakers, red glowing light in headphone jack

    Okay. Have seen a few posts on this topic, but scattered symptoms, resolutions and ideas. Here is my timeline and plan:
    My speakers went out spontaneously running 10.4.5 when I switched to battery power. We had a blackout here in L.A. and I was trying to play a DVD for the kids- no internal speaker sound.
    * There is a red light glowing from the headphone jack. Never noticed this before, it seems to be a sign associated with the problem.
    * External speakers/headphones work fine.
    * Absolutely no sound from any app, alert or startup unless something (speakers/headphones)external is plugged in.
    * if nothing is plugged in, the slider volume control in the menu bar is greyed out at full volume. Sound pref panel only shows "digital out" as choice, but is greyed out. "Built-in speakers" is absent as a choice.
    What I've tried:
    Select/deselect "look for spekaers" option in iTunes.
    Update to 10.4.7
    Update all listed apps to latest in Software update (iTunes, QT, etc.)
    Trash sound prefs
    Zap PRAM
    Clean install from OEM DVD
    Restore System from previous backup (although last backup may have been corrupt because I may not have noticed the problem for a while.)
    That's about it.
    My plan: Take PB to genius bar today and see what they say.
    I'll report back what they say.

    I have had the same syptoms as the above people in my PowerBook and was hating life without sound. i got to thinking about what earlier people had posted and concluded it could not be a software problem, that it had to be a hardware problem. I thought, maybe the headphone jack was just dirty, you know, plugging headphones/speakers in and out of the computer many times, it could have just gotten dirty. If I just clean it with rubbing alcohol, maybe that will do the trick. It did! I have been going two days and am doing great!
    THE BOTTOMLINE!
    Clean the headphone jack out! I used a q-tip and rubbing alcohol. (I have found that making my own q-tip with a toothpick and a small amount of cotton works better because it is thinner than the stick for a q-tip. Just twist the cotton to the edge of the toothpick.)
    For all you people out there who try this and it works for you post for other people so they can be more confident that it does work.

  • Red light inside headphone jack. no option for internal speakers.

    what do i need to do?

    A toothpick.
    Get a toothpick and wiggle it around in the audio out port until you 'flip' the switch for optical/digital out. The red light should go off and you should be able to select your internal speakers again for output.
    Seriously. It's worked for hundreds of people.

  • Red light headphone jack problem iMac 27" 2011

    I have a problem with internal speakers. I searched forums and I think is a problema about the connector, the red light in headphone jack is on. I cannt hear from internal speakers sometimes and now it's allways. I need to plug a headphone or external spekaers to get sound.
    I buy the iMac about 2 month ago. May I send the computer to the store or can I fix it?

  • Very low volume on headphone jack on MBP 13" but no red light

    Hi I am looking for solution for my problem where in I am currently getting very low volume on headphone jack. There was no problem before, everything used to work perfectly fine.
    I couldn't find comprehensive solution for this. Could anyone please point me to the correct thread if solution is already available.
    my details:
    MBP 13" Snow leopard, 10.6.5 - First Gen. Unibody MAC.
    problem: Very low volume when headphone is connected.
    Things: I have tried:
    1. Headphone is fine. Works correctly on windows PC and on my iphone.
    2. Tried system pref. volume is max.
    3. Upon connecting headphone to MBP it is detected as headphone.
    4. Tried Audio MIDI setup, settings seem to be correct 44.1KHz 2ch-16 bit
    5. There is NO red light from headphone jack.
    6 Tried poking toothpicks in to audio out but didn't help.
    7 Tried creating new temp. admin user account but headphone low volume remains.
    8. Tried safe boot - no joy.
    9 Safe boot was followed by normal boot-> Ran Disk Util tried repair permission. No luck.
    10. Also followed steps to clear PR RAM etc. - problem remains.
    11. Heard about logic board replacement but don't want to go by that route.
    Can anyone point me to correct thread or provide the solution..
    help is much appreciated.
    Thanks...

    I have the exact same problem. i have  a macbook pro 13in (mid 2009) with extremely low volume coming from headphone jack. i brought the computer into my local apple store today and they diagnosed my problem as being the result of a faulty logic board. my laptop is out of warranty so they have to send it to the apple repair depot for 3-5 days. the charge is a flat $280 (tax not included). the solution seems extreme though and i hope i don't get any "kernel panicking" with a new board. i will update... also there is no accidental damge to my laptop whatsoever. the problem arrose 2-3wks ago

  • 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!

  • 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.

    Is it a laser?

    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.

  • Internal speakers suddenly will not unmute.  My headphones work, and there is a red light coming from the headphone jack

    I put my volume on mute a few weeks ago, and I don't know if I have used it again since then or not, but now the volume will not unmute.  There is a red light glowing out of the headphone jack.  Sound through headphones works.  I've tried updating and restarting my computer.  Help?

    No, not forceful - gentle.
    A PRAM-reset might also help:
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.
    Try this a few times.

  • After installing an update I am no longer able to hear sound out of my speakers. A red light comes on where the headphone jack is. I have already attempted to trip to switch with a wooden toothpick in the headphone jack but have not had luck.

    Have you gone into system prefs nad made sure that the headphone port is set to audio out. And not audio in.
    Also make sure that you are selecting built in speakers for your audio output.
    If that does not fix it try doing a Pram reset.
    Shut your mac down.
    Press the startup button.
    Hold down the following keys. Command Option P and R. Wait till you hear the chime 2 times. Then let go. See if that fixes it.
