MacBook :: Red Light In Headphone - Sound Messed Up
Feb 4, 2009
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.

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.

first time i have ever come across. I have a Intel 2 MacBook Pro. There is no sound coming from the speakers even though it is not muted and the vol is turned to the max. There is sound coming if i plug headphones in the jack. Just noticed that there is a red light coming from where the headphone jack is...anyone have any idea how i can get my speakers to work again?

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.

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).

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 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.

I have a 13" 2010 MBP. When my headphones are plugged into the jack, and no sound is being outputted, the headphone jack seems to "turn off". If I want to do something that outputs a sound, like emptying the trash, there is a 3 second delay from when the trash is emptied to when the sound is played.

I have a 2009 macbook with version 10.6.4, 2.13 GHz intel core 2 duo processor and a 2 GB MHz DDR2 SDRAM memory. Last week I was using to play music through an auditorium sound system and it sounded strange. The next day I had lost sound through the right side of my head phone jack. The left side is good along with the speaker.

I haven't used my headphone jack in a while, so I don't exactly know what's going on but, internal speakers work fine, plug in headphones and it doesn't make a sound. I know my computer knows there's headphones in the jack because in the system preferences, it registered them, but still no sound. Also, no red light, though I will try the reset button inside. I've tried, staying plugged in>removing the battery> restarting>putting the battery back, and nothing. I've tried taking the battery out and back in without the cord and also, nothing.. so.. I'm stuck. All I wanted to do was listen to the funny people in my guild Ventrilo server.

Before my new iMac took 2 minutes to boot up and I re-installed SL and it is now fixed but now, like the 27 inch, the videos on youtube are really choppy and the sound is messed up. It only happens occasionally and is fixed with a restart and is really annoying. Does anyone know how to fix this?

Just this past weekend after watching a DVD (used the headphone jack to listen) I am no longer able to hear anything out of the speakers. I also now have a red LED light shining through the headphone jack. Under the 'Sound' option in System Preferences, it says "Digital Out" instead of "Internal Speakers". I've called Tech Support and they haven't been able to help me. My next option is sending my laptop back in to them for service. I'd like to see if there if there is somebody out there that has had this same issue before I lose the laptop for atleast a week.

I have a macbook osx and until recently I could listen to music and sound files okay using my headphones. But although the internal speakers are working fine, I cannot use my headphone or external speakers. I tried clicking on system preference and clicking on headphone output, but still didn't succeed in getting the headphone jack work. I am sure the problem is simple, since the internal speakers are working fine.

My mums macbook has gone crazy! There is no sound coming from the macbook, and when I went to check if the volume was up the volume box popped up as usual but with a symbol, similar to a no entry sign. Circle with a cross through it. Then I saw a bright red light from within the audio jack itself. When I plugged in ear phones it works fine but the built in speakers are not working.

I have a stereo hooked up to my iMac and everything sounds great. What I'm wondering is this. Is there a way to have sound come out of BOTH the internal speakers and the headphone/audio out jack?

I want to plug in both my computers input and the hdmi audio out from my monitor, and use the same speakers, but I don't want to have keep switching the cord, so I bought a splitter. Do you think it will reduce the sound quality significantly? I want it to be easy, but it's not worth cutting way down on quality.
