Getting red light on the audio port

Hi, im not able to get sound on my macbook, ive tried using a headphone, and it works fine, but as soon as i plug out the audio jack, i see a red light on the audio port, and the sound icon is grayed out...
I've read similar problems on the forum, but could not get a resolution, can someone help me out with the correct resolution of this problem????

the toggle switch inside the audio jack it flipped the wrong way, so your mac still thinks your headphones are still plugged in. Try to rapidly insert and remove the headphone jack in and out of the port to toggle the switch back.

I left my headphones into my new macbook pro and now there is no volume through headphones or without. I have tried to reset the audio port and it is not on mute. Any ideas?

Go step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure that Mute is not enabled.
2.Plug in and remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset PRAM. http://support.apple.com/kb/PH4405
4. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
5. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

My speakers on my macbook receiently quit working after I had been using some headphones. My headphones still work whenever I plug them in with both increase and decrease in volume. I have also noticed a red light on the inside of the headphone jack.

My speakers on my macbook pro quit working the other day after using my headphones. when I try to adjust the speakers my screen indicator sayes that it is at full volume on the bar but also muted(circle with line through it). I also noticed a red light inside my headphone jack. My headphones still work including volume. Any quick fix?

Hopefully one of these steps should solve the problem.

I have a MacBook Pro. My mac can detect wifi. But will not connect. I did get connected vis TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest.

Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

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.

Iphone 4 dead, red light above the speaker

hey, my iphone suddenly died yesterday. i was texting, browsing normally and couple of minutes later it was dead (battery was almost full). i tried hard reseting it, connecting it to my mba and nothing, itunes doesnt even recognize it. couple of hours later i saw this red light above the speaker and after some googleing i found this discussion
https://discussions.apple.com/message/16706124#16706124
where it says that the red light means my iphone was damaged by water. the only thing i dont get here is HOW since i havent dropped it, nor used it outside in the rain haha. i am kind of confused because i dont know if its dead or not. right now it's resting in a zip bag full of rice but i dont get it. could someone help me? thanx
i mean, its an iphone 4, ive been using it for years and this is the first time this happens, battery works great, phone works great i dont wanna change it. the only good thing is that it's helping with my addiction to internet hahhaa, first 20hours were baaaaad. thank you

Hey there lildl110,
Let's get that iPhone 4 to cool down. It sounds like the phone overheated and needed a bit of a rest. Is it still too hot to touch? If you've given it some time to cool down please try the restart method,http://vz.to/1ciOvXw.

Red light to the left of the receiver of the iPhone 5

I had my iPhone 5 replaced at the weekend for a speaker issue, but I noticed today when using the replacement in a dark room, I can see a glowing red light to the left of the receiver. I did a search, of course, which brought up results concerning the iPhone 4 and that it's the proximity sensor and not something to worry about. But I also saw this "eHow" article that says it's because the phone's been exposed to water:
http://www.ehow.com/info_8704998_red-light-iphone-mean.html
Earlier today I was using the phone when it started raining, so I quickly wiped it against my sweater and put it in my inside jacket pocket. I didn't think that would be enough to cause any damage to the phone and the phone is working fine, but now I'm a bit worried, having not noticed the light before.
Is the eHow article wrong or do I have a reason to be worried?
Thanks in advance for any help.

That's one of the most absurd things I've ever read...the light is part of the proximity sensor. The sensor is an infrared light that can appear red when viewed through the front glass in a very specific way in the dark (the glass distorts the infrared light enough to make it very weakly visible). This is totally normal and nothing to worry about. The water sensors are round white stickers in certain locations on and in the iPhone. When they get wet they turn red and do NOT turn back. The sensors wouldn't be very useful if they changed back when the phone dried...

I have a record player hooked up through the audio port. The input volume is registering high, but there is no output anywhere. Help?

I have a record player hooked up to a preamp which is hooked up through the audio port.The sound settings are set to have the audio port be "input". The input volume is registering high with fluxuations in the sound settings, but there is no output anywhere. Do I need some sort of third party application or widget to hear the record i'm playing through the speakers that are hooked up to my computer?

keithstopher,
You may want to check into a USB interface, as I believe you have a Mac with the single audio port, which can be used as input OR output.
You may want to check into something like the following, there are may out there, see what fits your needs best.

The audio port on my Imac is not working,what can i do to fix this?

I've got a mac pro problem with the starting up, but also a red light on the logic board solidly on. Its not among the diagnostic led. It's located near the BT adapter and the front fans. Also the fans run loud also. any solutions?

Hi
I've got a mac pro late 2006, and i am having problem with it for quite a while now. the problem i am facing is the start up process, and the red light on the logic board. Earlier I've got the two led on the diagnostic leds 5 and 6 turned on without the diagnostic button being pressed, and i think those are related to the processors overtemp. I've managed to solve that by, removing the processors and re applying the thermal compound on the heatsink. what i have left now with is the red light on the logic board at the time i plugged in the power. At the same time when this light come on, the power indicator at the front panel come on as well. i am not sure what is this light relates to. We've replace the power supply too, and gone through the SMC reset but seems no help.
Any idea on the problem? I am desperate about it, and i will be greatful if anyone can help..
thanks and hope for your best solutions

I can't help directly with your problem but you might check here http://tim.id.au/laptops/apple/macpro/ for a service manual which could answer your question.

Unable to insert earphones jack in the audio port

I am unable to insert the earphoen jack completely into the audio port.

You may want to clean it since debris could be in there. Otherwise I blame the headphone jack, which may be too short or not of the correct size (3.5mm). So a "mobile" headset would not fit because the diameter is 2.5mm

Red lights behind the power button

In reading through some posts last night I got the impression that I should be paying more attention to the lights inside the box, behind the power button, when booting (or I should say attempting to boot) my dual-core G5 PowerMac.
My observations this morning are that I see a big red light when the machine is first powered up from cold, and also when it is restarted. That goes off. A few seconds later, before the chime, I see a brief, much smaller red light flash in that same area. Almost a pinpoint.
Is that normal, or is it diagnostically significant?
(As noted in my earlier post today, I'm launching a final effort to fix this sick puppy before I give up and take it down to the Apple Store, but it needs to be a campaign of controlled baby steps.)
TIA,
Kathi

Hmm, on second thought I'm not so sure... but I don't have time to open the thing up right now and figure out exactly where each of those LEDs is. The drawings in that article and in my manual aren't terribly helpful.

Why does my iPhone 5c have a red light on the top of it

my iPhone 5c has a red light on the top of it next to the speaker but it is only visible at night, it's really scary

It's the proximity sensor.

Link Light on the Ethernet port ?

Hi,
Is there a link light on the Ethernet port on the MacBook Pro ? It looks pretty dark to me ;-(
MacBook Pro Mac OS X (10.4)

No I have a feeling it's a 2-bit ethernet card, not a gigabit one.
I just opened up the box yesterday. I thought the
world of Apple was going to be better.
I am going to locate an Apple Store next week to see
see what their repair calendar looks like.
