Light leaking through Headphone jack

I don't know if this is normal but at full brightness in a dark room (no light), I noticed that I could see light coming through the 3.5 mm audio jack. Is this normal or will it affect waterproofing?
Thanks

Yeah its normal!!!! In almost all of the phones that I have used, I could see the light through the headphone jack!!!

  • Red light from macbook headphone jack

    So, after using external speakers, my sound stopped working...and the audio jack was shining red light. I looked through old threads on this site and saw that there were several different ways to fix the problem (I used a toothpick and it worked..) Only- my volume is now working fine without headphones- but there is still a red light. All the responses I red said that the light would turn off when volume started working....why is my volume working and the light still on?
    Does it matter that there is the red light, if my volume is working fine...?
    thanks!

    meh!
    Excuse my lack of tech knowledge- but all I was using the headphone jack for, was for headphones and for connecting my macbook to external speakers. So, I didn't know the port was used for anything....else?
    Last thing- I don't remember when I first saw the red light anyway. I was using my computer in the dark and I saw it...and actually thought that (silly me) it was such a convenient thing to have (a shining red light) specifically so we could see where to insert the headphones or whatever if it were dark. (HA!) But then recently my volume has been getting messed up if I leave something in the headphone jack for too long....
    If it isn't too much of a problem I wont worry. There are worse things.. thank you!

  • No sound through headphone jack, no mechanical problem, what to do?

    I have verified through resetting my new iPad, that there is noe mechanical problem with my headphone jack. it works fine until I reinstall my backup. Thus it is a software issue, byt what? There is no selection for output jack problems in support, just look at the menu options for posting on iPad. Nothing on connections like the headphone jack. Strange.

    Steinar-
    Your problem may be due to a software issue, but it is not normal.  If you are near an Apple Store, demonstrate it to an Apple Store Genius.  If the Genius can not fix it, you may get a replacement iPad.
    One thing you can try while the headphone jack is not working, is to reset (reboot) the iPad.  Hold both the Home and Sleep buttons for several seconds until the Apple logo appears.  Ignore the "Slide to power off" arrow.  The iPad will restart after a couple of minutes.  Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

  • 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.

    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.

    Do you think any damage would be readily apparent right away, in the form of pronounced discomfort or noticeable vision problem?

  • Constant static through headphone jack

    Playing audio through the Mac's own speakers - no problem, but audio through the headphone jack = irritating static / whitenoise as well as the audio, the right side worse than the left.
    I tried with a number of different headphones and speakers through the jack, which showed that the problem wasn't the headphones. This is an 18 month old iMac.
    When I took the Mac to an authorised repairer to get the optical drive replaced recently, I reported the problem with the headphone jack, and they replaced the wire between the motherboard and the jack thinking that would fix the issue, but it hasn't. They suggest replacing the whole motherboard (for a further outrageous cost (I'm no loner in a warranty period)). An earlier discussion in the community thought the problem could be resolved with a grounding adpater on the power cord, but in Australia we don't have that problem because all power is grounded.
    Any advice on what exactly the problem is? The repairers couldn't say, but I note that a number of people have reported this issue but not posted any successful fixes. Any suggestions?

    you could also try a reset.
    PUSH AND HOLD the middle button and the menu button AT THE SAME TIME for 10 seconds.. this may take a few trys and it works best if hooked to power..
    you could also try a restore but if you do backup your information because it will erase your ipod

  • How to silence ring through headphone jack.

    I have occasionally played music from my iPhone out through the headphone jack and through our in-house audio system at church. Which usually is great. However, if I get a phone call while the song is playing from iTunes, the ring comes through the system, even though I've got the phone silenced. Any idea whether this is even possible to correct? Obviously, having a phone start ringing through the PA during the middle of a worship song is pretty annoying.

    Put the phone in airplane mode. That will turn off all iPhone radios. You can still use the ipod function in airplane mode.

  • Does anyone else notice the light from the headphone jack on their white iPhone 4?

    I noticed that whenever i turn on my lockscreen or whenever my iphone's screen is on, you can see light from the audio headphone jack. Anyone else have this problem? ( Iphone 4 white)

    Clarification, iPhoneMac is correct. There is light noticible at the bottom of the Headphone Jack.
    However, when I responded, I checked the 6 iPhone 4 here and none of them showed this in lit room normal usage. In Dark Room especially with the Screen Brightness turned up you can see a bit of light (glow) at the very bottom of the Jack, if you look right down the barrel.

  • !!! HELP: Connect nano to stereo through headphone jack?

    Is it possible to connect an ipod nano to a stereo system through the audio minijack/headphone jack? I was sure it was possible, but now it doesnt seem like it.. I've got a nano, but havent opened it yet (its my birthday present..) and nearly the whole point of me getting it was because I wanted to play it through the stereo!! Im seriously considering returning it! Isn't there an adapter or something, other than those crappy 3rd party fm/cd/tape ones that you can use?? do you HAVE to get a dock or some expensive thing?
    I know that they left out the a/v jack on the nano but I thouhgt that was mostly for connecting to a tv and you could use headphone jack for just audio.. im so bummed out. my mom's been calling stores for me and asking them and they say it's not possible. grrrhh
    please let me know if there is some way..!!!!

    I know, tried it and it worked
    shows them stupid store staff who dont know sh*te about the things theyre selling!
    I LOOVVEEE my nano so far! It ROCKKSS!!! <3 <3
    thanks you guys + for the replies

  • 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.

  • IMac G4 plays through one speaker on stereo system through headphone jack

    Ok so for some reason the headphone jack won't allow me to play music on my stereo in surround sound. It just plays music through one speaker. i have adjusted the balance on my amp but now i can only play through 2 out of 5 speakers? help please! headphones work properly but not sound system?

    That's normal, unless the stereo system has an upmixing matrix program in it, and then you have to actually engage it.
    So do you have a surround sound receiver, or just a stereo receiver, or is it just an amp?

  • HP Pavilion Dv7 Windows 7 No sound through headphone jack or speakers

    Hello. I have been having trouble with the sound of my laptop for quite some time. 
    I discovered this forum, and was trying to find my laptop's problem, except I found that I could not find a thread that pertains to my laptop's individual problem. As stated in the title of this thread, my laptop does not play sound through the headphone jack or speakers. However, when I plug in a usb headset the sound works. I want to rule out the possibility that this is something I can fix myself before I have this computer sent in to be repared. 
    I have tried uninstalling and reinstalling the software that runs the sound (I forget what it's called). I also tried turning off the laptop, removing the battery and holding down the power but ton for 30 seconds; that didn't work. I have tried making headphones and speakers the default audio, except that didn't work either. It seems that maybe my laptop is just broken, and this is the second time this has happened. (The second time, what the hell!)

    Hello Pandabear277 and MicrosoftUser,
    What is your product number and operating system?
    Thanks

  • Audio through headphone jack

    Got new Q10 BB and most apps will not play sound through the headphone jack but rather only through the speaker. The exception so far is the slacker radio app which does play through the headphone jack fine. Through this support forum i have made sure the TTY setting is off and went thru turning the hearing aid feature on/off to no avail. i have verified that the BB software is up to date. Suggestions as i cant be the only one with this issue.  

    Have you tried using another HeadPhones ?

  • No sound through headphone jack even though it's been replaced...

    I'm hoping someone has some info, i've rang the support line three times and have got nowhere!
    Basically, i have an ipod 4th gen Nano 16gb and a few weeks ago i suddenly got no sound coming through my headphones or speakers. I was quoted for a headphone jack repair, had it done and when i reeived it back the unit was still not working and it was suggested that i have a problem with the logic board.
    However, this work was not carried out by Apple so i'm not sure how this wouls affect my chances of them repairing/repplacing.
    The Nano is also out of warranty.
    My ipod only gets occasional use, and i've never had any issues with it before or dropped/damaged it in any way.
    Basically i was just wondering if anyone has any thoughts as to when i go to the Genius Bar whether they would replace my ipod even tough it is out of warranty. I only ask because a similar thing happened to my friend and his was replaced...

    Try the Microsoft audio fixit.
    There were no BIOS updates related to udio issues released for your notebook.
    What is the service pack level of your Windows 7 OS?
    Have you been installing Windows updates?
    Did this issue just begin recently and did it occur after a Windows update was applied?
    Post your results here please.

  • No Sound Through Headphone Jack When playing Video

    Hi All
    I got a strange problem. My MINI stopped playing audio from videos through the headphone jack.
    This includes iTunes, QuickTime, and Youtube. Audio files in iTunes work fine. If I unplug the headphones all is OK. I have tried the Audio MIDI setup, starting and stopping Garage Band, but no help. I know it used to work but I am not sure when it stopped.
    Any help would be greatly appreciated

    Had the same problem. My sound was fine until it suddenly went stumm from one day to the next. This fixed it in 3 seconds:
    1. open /Applications/Utilities/Audio MIDI Setup
    2. check the properties for Built In Output.
    3. It might be set to 96Hz. Change it to 44.1KHz
    No idea what caused it to be set to 96HZ though.
