MacBook :: Red Light From Headphone Port?
Nov 5, 2009
I went to plug my headphones into my Macbook and I noticed that the tip of the plug was glowing red, when I turned to look at the side of the computer I nonticed that there was a red light being emitted from the headphone port and the sound icon on the menu bar was grayed out. Is there actually a light in there? What does it mean? I'm uploading pictures right now, they'll be up in a few minutes. My MacBook is a late-2007 White MacBook running 10.6.1.

My 15" late 2006 MBP has just stopped producing sound from the internal speakers and for the first time there is a red light visible inside the headpbone output port. Apple support says contact support but since I'm a long time out of even my extended warranty.

I've had my macbook connected to my speakers for much of the last couple of days. I reckon I last had sound from my actual macbook speak the day before yesterday - No nothing! The speaker icon in the menu bar is greyed out and in system prefs, all is normal and not muted. When I use the volume keys, the window comes up but the volume indicators don't move up or down and there is the forbidden/ no entry icon underneath the volume indicator bar. There is also a new red light omitting from the headphone port. (I'm using Lion 10.7.3)

I was just listening to some music through some speakers on my old 1.8ghz cd macbook and then I unplugged the cable from the headphone jack and noticed that there was a red glowing light coming from the headphone jack. Now my sound is messed up, sound works properly only when something is plugged into the headphone jack. Nothing will play through the internal speakers when I try to adjust the volume with nothing plugged in I get this.

Last weekend, after I took my headphones out of the computer, I couldn't get any sound from the mac, and the volume controls on the keyboard didn't work. 5 minutes later I noticed a red light coming out of the headphone jack. I looked around for answers and apparently all you need to do is stick in a matchstick or Q-tip and wiggle it around to fix the sensor. It worked the first time. I could get sound from the mac and the next couple of times after unplugging the headphones, everything was normal. The problem has come up again, and I'm looking for a permanent fix. Am I looking at a trip to the Apple Store to get it fixed, or is there something I can do?

What's up with the red light coming from my headphone jack. It only turns on when I am in Windows XP via Bootcamp. It doesn't turn on while using OSX.

Basically I dropped my macbook pro and ever since I have not been able to get any noise out of the speakers or the headphone jack and there's a constant red light in the headphone jack (I have tried the toothpick method).

The sound doesn't work! I turned on my laptop and there is no sound. When I press the up and down volume buttons, it's normal, but there is no noise. Also, there ISN'T a red light in my headphone jack.

When I plug a set of headphones on my macbook pro, it no longer recognizes that headphones are plugged in. I have tried three different sets of headphones just to make sure that they are not the problem. In Sound/Output section of system preferences, it still says internal speakers even when the headphones are plugged in all the way.
Is there a fix for this I can do myself or do I need to take it in to an Apple Store?

Since doing a clean install of Mavericks (which solved a ReportCrash loop problem), everything has been fine except..for some reason the 3.5mm headphone port refuses to acknowledge the existence of headphones when plugged in. The internal speakers do not cut out. No sound comes through the headphones. If I go into Systems Preferences/Sound/Output there is no option for headphones sound, just internal speakers.Â
I have tried everything (deleting .plist files and rebooting, booting in safe mode, PRAM resets etc etc). I have also tried various sets of headphones (mono, stereo and three ring headphone plugs). They all don't work on my MacBook Pro, they all do work (and make the internal speakers cut out) on my MacBook Air. It's not the headphones.Â
The port will happily recognize, charge and download my iPod nano. I am convinced this is an OS problem, as the port has not suffered any shocks, and it happened directly after a clean Mavericks install. It was working fine on Mavericks before the clean install.Â

I am on an iMac, and there is a weird red light that comes out of my headphone jacks. But it is only sometimes that it happens. It also happens in windows. What could this be? Is my iMac Intel possessed?

1. The optical light is always "ON" on the headphone hole only on Win 7 but not Leopard. How do you get rid of that?2. Keyboard light would not turn off at the lowest setting. Sound is not as loud as well. I downloaded the latest Realtek audio driver and it's still the same.3. 9600m GT is always on. I would like to use 9400m instead since it saves battery.

My built in speakers work fine all the time, even when I have headphones plugged in. I looked under the output devices in the system settings and the only option is for built in audio output, a.k.a speakers, there is no option for an alternate audio output, a.k.a headphones. When I plug in my headphones nothing happens, sound continues out of the internal speakers like nothing happened.I have Mac OS X version 10.4.11.. iMac7,1.. 2 Ghz Intel Core 2 Duo 1b 667 mgz DDR2 SDRAM

So I just received a used macbook that has something stuck in the headphone port. What this means is that os x wants to use the optical out (digital) and once it does that there is no way to use the internal speakers. And, because it is stuck, I can't use headphones either. Temporarily, I am trying to use an old USB external Creative sound card for my audio, but when I plug it in all it does is recognize it. I tried plugging into every port but nothing.

Is it possible to have the Mac Pro output signals from the optical and the headphone port on the front of the case? I like to have my speakers going as well as have one cup on my ear when listening. Surely there must be an application out there that forces OSX to do this.

My MacBook pro charger port isnt working. I use my charger for my sisters laptop and it works therefore indicating that the charger isn't the problem but when I charge my laptop it shows a faint green light but not charging! It's cause water spilled on my laptop the day before but it was not a lot & I let it to dry but everything works well except from the charger port!

How many of you would like to see a HDMI Port? Why the miniDisplay port? Why not remove ethernet jack and miniDisplay port and replace it with a HDMI port. That way one HDMI cable feeds digital video AND audio. Am I the only one thinking of this?

I have just ordered a new MacBook Pro and it does not have enough USB ports for my needs.If I have a USB 3.0 hub and I mix USB 2.0 and USB 3.0 peripherals on it, will the whole hub/computer USB 3.0 port be slowed down to USB 2.0 speeds?I am thinking back to Firewire, if you have Firewire 800 and 400 devices on the same chain, the whole chain slowed to Firewire 400 speeds.I don't think this is the same with USB but wanted some reassurance..

I am having issues with my Dual Band 1TB time capsule for some reason the damn ports won't forward I have enabled the correct settings with the ip address and the ports, but when I use a program to test if the ports are open they are always closed, regardless on pc or mac. Does anyone have a solution to this? I even reset my Time capsule to see if it would work, but no luck.

Here's the deal, I am so frustrated. I am trying to open port 59152 for Transmission on my Macbook Pro. I have the latest releases of everything, I am using an Airport Extreme base station with an older airport to boost my signal/connect my tivo w/out a wireless adapter.
I have managed to get it open in the past but there was an update or something a month or two ago and at first it was still open and then it closed. I don't know what changed with the update, all I know is that I did n't change anything.
I have granted permission for Transmission to accept incoming connections on the firewall, little snitch allows it too. I have lighthouse, which worked at first but now I don't even know why I bother having it run. I have the port mapped through the airport utility.
PLEASE don't say to go to portforward.com because they haven't updated the Airport section since Leopard came out, yet every search I do someone repeatedly tells the person needing help to go to [URL]
I am going to attach some screen captures so you can see what I've got going on and maybe point out something I've missed.

Relevant newbie to the mac world. I have a MBP late 2009. I bought a third party Mini display port to HDMI converter so I can hook the MBP to my 46" Samsung screen.
This works fine, no major issues here. However the picture is not great. I compared watching a standard definition TV show through the MBP then burnt it onto a DVD. The DVD (using the PS3 as my DVD drive, connected via HDMI) had superior quality than through the MBP.
Also the picture does not quite fill the screen. There is a small black border running all the way around the screen. Does not sound significant but when doing the same comparison as above, you notice the difference when via DVD the movie fills the screen. I have played around with the resolution settings. Those that fill the screen chop bits of the mac desktop off, so thats no good either.
So I am wondering why this is? Is it because the mini display port is not a DVI port, hence I am not getting true HD quality picture? How can I overcome this if at all. I'm thinking of getting a mac mini as a media hub/HTPC but want to ensure I dont encounter the same problems.
