Output speakers do not work, have a red light coming out of my headph. jack

My headphone jack works but theres a red light coming out of my headphone jack when its unplugged and my internal speakers will not work...anybody have an idea? Tried system preferences and says no options for selected audio and cant get any sound for my built in output speakers and my volume display in my bar is faded....HELP!

@Spencer
I know this thread was marked answered but thought I should chime in since my MBP (2.66Ghz Late '08, bought May '09) started to exhibit this behavior. I was getting "No Output" greyed out speaker images and the red light coming out from the headphone jack. It's been intermittent but finally wouldn't go away so I figured I'd contact Appe.
This afternoon I called Applecare and was advised to take it to the Apple store... no questions asked, no troubleshooting steps, just told me to take it to the store and even offered to make me an appt. I was able to get an appointment at the genius bar same day (literally 2 hours after I hung up the phone). My wife took a ride with me and we headed down there.
When I showed the technician she tested it and then went to the back room to double check something. When she came back she told me that it was hardware related and needed to be sent in for service. I am under warranty so it was no skin off my back but I will need to be without the machine for a few days.
I agree with Rod to take it in, esp. if you're still under warranty. I should also mention that this only started happening a few weeks ago but the red light part was rather sudden.
Good luck!

Speakers not working have a red light

i can hear out of the head phones but the interal speaker will not work

If you're seeing the red light, that means your MacBook thinks there's a digital audio device attached. If replugging and unplugging your headphones don't reconfigure the switch, you can use a toothpick or--carefully--a paperclip to toggle the switch yourself. It's halfway in, on the 3:00 side.

Audio muted/disabled- red light coming out of jack????

what the heck? anyone know what's going on here? red light in my headphone jack and volume control non-operational. reset the PRAM to get speakers working for a moment before problem returned. works fine when headphones in, but not without.
and the red light shining out... what IS that?

Hey all-
I've worked on laptops before and didn't feel comfortable sticking a metal clip into it. I did snap the end off a Q-tip and wiggled the cardboard ever so gingerly and it went off. BUT later in the week the same problem occurred. I've got an appointment with Apple tomorrow and will keep you up to date on the "official word" with this problem. I'm still in the year warranty period (refurbished pruchased, year up in November) so they should replace anything that is failing this soon in the game.
Have a co-worker that just had a new MBP's video fail after less than a month of use---Apple replaced the whole machine, but only because it was in the first 30 days of purchase. Doubt they'll make me the same kind of offer. Still sorta miffed to have problems with my newest machine. Never had to get AppleCare, but think I'll have to with this guy... hope it's not IceBook Logic board blues for these first Intel offerings.

I have been experiencing a red light coming out the audio jack and no audio coming out of my Mid 2009 13.3" Macbook pro. I was wondering if Applecare would cover whatever this is?. I am covered until september 2012. Thanks

Can anyone help?

It should be covered. Contact Apple support

for options available to you, or take your Mac to an Apple Authorized Service Provider.

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.

How to switch off the red light (optical out) on my Audigy 2

I am not using the optical out most of the time, is there a way to switch off the red light coming out of optical out?red light is causing heat leading to cracks on the surface of the card.Please help soon. thx

Are you sure? AFAIK, LED's don't produce any significant amounts of heat. And, no, I don't think the light can be switched off.

Red light coming from my audio output, speakers not working

I read somewhere about wiggling a toothpick around in there, but that didn't work, any other ideas.
This happened after I had a 1/4 to 1/8 converter plugged in there to use a little mini amp.
I've lost the use of speakers.
headphones work fine
I think the optical input is still reading as if something is plugged in. Not sure if there's something in my system I need to switch, or if I need to take it in, have the jack opened up and replaced

Just to rule out the obvious make sure your mute switch (F3) is not on. If your 'switch is stuck' you would see a red light coming from the headphone port.
Double check your Sys Prefs - Sound settings ...if things still are not working you might try a SMC reset followed by a Pram reset that would restore your orig. settings.

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.

I cannot hear any songs or movies from my laptop speakers - the headphone port works and a red light is showing? The output sound settings are showing as digital optical only? Any ideas :)

I used the headphones in the laptop for the first time yesterday and have had this problem ever since. Any ideas

The internal switch in the audio output port is stuck. Try inserting the earphone plug a few times. If no success, try jiggling a tooth pick inside in order to trip the switch.. If still no success, have the technicians at the Apple store genius bar do it for you.
Ciao.

My ipod speakers are not working unless I have my headphones plugged in?

So I accidently dropped my ipod in the toilet:( i immediently turned it off and put it in a bag of rice. When i came to get it out of the bag i noticed that my speakers were not working and when i turn up the volume it says i have my headphones in, and when i plug my headphones in the speakers work fine. I found out that there was some rice lodged in the headphone jack but i got it out with a needle and my ipod still thanks the headphones are in? I dont know what else to do, Please Help!!

Have you tried the standard fixes to rule out a software problem:
- Reset. Nothing will be lost
FIX for iPod Touch Home Button: Apple Support Communities
- Restore from backup
- Restore to factory defaults/new iPod.
If still a problem you have a hardware problem. It could be the headphone jact or something else.

Internal Speakers do not work at all

My sound was working just fine a few days ago, and all of a sudden, there is no sound at all comming from my macbook pro. I have tried plugging in headphones and still there's no sound comming from there neither. I don't even hear the chime at start-up. I have looked at a couple of fourms on here and tried everything from toggling with the headphone jack to reinstalling OS X Mavericks but still no dice. There's no red light showing up in the headphone jack, and the interna speakers are not showing up at all in sound preferences. I don't know what is going on, i have tried everything! What should I do? Do I need to buy a new sound system??

I'm having the exact issue. I, too, have done everything I know to do to correct it. I've never had a moments trouble with it until I update to OS X Maverick the other day. I sometimes plug my computer to my TV via a HDMI cable, and the sound plays through the TV just fine with that. The only thing left I know to do is to take it to the Mac Store....

My speakers are not working but it still makes a sound when it boots up

my speakers are not working but it still makes a sound when it boots up.

Take each of the following steps that you haven't already tried.
1. Start with the steps recommended in this support article.
2. If your model has an audio-out (headphone) port, and a red light is coming from it, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
3. Boot in safe mode. Don't log in; just reboot as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
4. Reset the NVRAM.
5. Reset the SMC.
6. Reinstall OS X after backing up all data.
7. Make a "Genius" appointment at an Apple Store.

Macbook Pro 17" - My built in speakers are not working.

Macbook Pro 17"
My built in speakers are not working.
The speaker logo is not highlighted (grey not Black) and when in sound options "output" pane only displays the digital out for 'optical' - ie, the internal speakers dont register (headphone socket works)
Any ideas?

1. If red light is visible in the headphone port, plug the headphone into and out of the port 5 or 6 times
     to flip the microswitch inside the port. Hopefully that will make the mode revert back to analog from digital.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC.   http://support.apple.com/kb/HT3964
     Choose the appropriate method.
Hope any one of these steps helps.

Sound Speakers are not working! Not allowed to control the volume! Why?

Hello,
Digital Output is not working on my iMac PowerPC G5 with Tiger. Suddenly, sound disappear and I was not allowed to turn on the volume through the keyboard buttons; a "not allowed" icon confirms that.
First I thought It was because Perian, Quicktime plugins, libraries, etc as I have read searching on these forums but I have just installed Mac OS X from the default install disc after formatting but the problem is not solved!
Speakers do not work but headphones and airtunes do.
Did the iMac Sound Speakers die?
Help me, please!

Imac G5 OS10.5.3
I have the same problem but with a twist:
In system preferences:
Under sound:
Output selected:
Under name: Digital out
Under type: Built in audio
Below that : settings for selected device
It says:The selected device has no output controls
It won't let me adjust the audio up or down, no sound.
I can hear the chime when the computer comes on, though.

Output speakers do not work, have a red light coming out of my headph. jack
