Internal speakers silent

There is a red light coming out of my headphone jack. The internal speakers don't work but when I plug speakers in they work fine. Also, I don't know if my internal microphone is working. Nothing bad happend, the red light just came on and they stopped working. Help.

I think you will find that the headphone jack on the latest PB's doubles as an Optical Digital Output, this will be the red light you are seeing. Have a look at the sound control panel and there may be an option to turn the Digital Output off.

MacBook Pro: No Audio from Internal Speakers - Solution

Issue: (MacBook Pro late 2010) Absolutely no audio to internal speakers after OSX has booted up.
Digital Out is the only available output device shown within System Settings
Analog headphones work
Digital Out works
Bootup "BONG" works (and is of course now perma loud after PRAM reset... uggh)
Things I have tried from least drastic to greatest in the following order:
sudo killall coreaudiod
Clear PRAM
Using Deploy Studio (first performing DiskUtility format as well):
re-image MacBook with a the same original OSX Lion image it has been working with for the past 3 months
re-image MacBook with previous Snow Leopard image (obviously used to work)
Not using Deploy Studio (but first performing DiskUtility format, using original supported installation media: DVD, Apple Store):
Installed Snow Leopard (no audio), then upgraded to Lion through Apple Store (still no audio)
Installed Snow Leopard using installation DVD provided with MacBook Pro (< waste of time as the above step didn't work either, but including here for completeness)Note: Even the "Welcome to Mac" intro movie is silent, audio controls are crossed out
Gentoo Live DVD _works_ (after enabling Front Speakers using alsamixer other wise it was also muted and no audio would work except through head phones)
Well holly $%#$%, %^#&^. After performing step 5, and enabling Front Speakers using alsamixer, I now have audio in OSX Lion
I believe this happened after I used the Mini Stereo jack for Head Phone use.
How in the ______ did this happen? And why did it take a third party software to _somehow_ enable audio to the internal speaker _after_ OSX Lion completely booted?????
Note to all: You can probably use a Ubuntu Live CD to perform step 5. Or any live cd that loads up Intel Audio drivers.

I appreciate your response. I still have concerns:
The red-lite is off when my issue is happening.
The red-lite is on when my issue is happening.
It was not consistent. My concern is the Macintosh operating system not detecting the change. My other concern is it can _not_ be only a hardware switching issue, as Alsamixer, a software program, can make the switch toggle between off or on. If it was a hardware-only issue, Alsamixer would be a fail. And, if it is actually a hardware-only issue triggering a software 1 or 0 switch somewhere:
My final concern is 'where is this setting being stored' as clearning PRAM and reinstalling entire operating system after opertating system (Leopard to Lion and back to Leopard) after a disk wipe has no effect.
I guess it sounds to me, that OSX tries to be too user-friendly by not allowing peeps to change those options themselves. Is there a dscl command switch I can use to manually override such an effect? (Just in case I don't happen to have anything to stick into the mini-jack port)
Regardless, your answer is correct. Thank you both (Ciao and Allan Jones)

No sound on internal speakers

Yesterday I joined the "no sound on my PowerBook club"... like many times before I connected my laptop to my stereo via audio cable (3.5 mm male connector)... after I took the cable out I lost my Internal Speakers... in SysPref>Sound>Output I have only Headphones on the list... no internal speakers... I did a few things listed on the net (except of formating the drive) and I came to a conclusion that no one has actually solved this problem...
to sum up: I can use headphones and in that case there is no problem with the sound... but internal speakers are silent no mater what I do... I believe that this is a software problem, that somehow OS X thinks that the cable is still plugged in the audio port even when it is not...
please help

I recently had the same problem. Sound worked through the headphones, but did not work through the speakers when I pulled the headphones plug out.
Next clue was to have the Sound system preferences panel up on the screen. In working machines, inserting the plug into the jack causes the output display to change from "Internal Speakers" to "Headphones." In my case, there was never any change, the display always showed "Headphones" whether or not they were plugged in.
In most audio jacks I have seen elsewhere, the insertion of the audio plug moves a metal contact so that it is touching the plug, but that it breaks a connection inside the jack. It is this circuit break that is the electronic signal to change from speakers to the headphones plug. I suspected that there was something that was preventing the contact from re-connecting when the plug was pulled.
I used some professional dust cleaning material (canned compressed air or other agent, dry not wet) through a tube into the jack. After a liberal use, the "Internal Speaker" indication came back up on the Sound preferences output panel.
The system now works. The plug still feels a little spongy when inserted (as opposed to a distinct click at the end of the insertion), which may mean that there is still some stuff wedged in the back of the jack. Because of lack of tools and experience, I have not chosen to open up the case to visually inspect and clean around the jack.
But it works now, so I don't need to open it up.
Have fun,

Internal speakers and line out at the same time?

I'd like to connect my Touchsmart 300-1125 to my stereo amplifier, to sometimes be able to play sound through the amp. The problem is that the internal speakers go silent whenever there is a cable in the line out jack (3.5 mm), so for times when I don't need the amp I have to fiddle with the cable to enable the internal speakers again.
Can I configure the audio driver so it doesn't disable the internal speakers when there is a cable in the jack?
(note that my model doesn't have the audio "phono" plugs on the rear, just a 3.5 mm headphone jack on the side and a 3.5 mm line out jack on the rear)
Thanks
Mike

Thanks Vidya,
I was hoping for a solution in the direction of your second link, ie a driver upgrade that would offer more control over the audio chip settings. It seems though that Analog Devices that delivers the audio chip for my Touchsmart doesn't offer any driver downloads, and refers back to the PC maker. And there is no audio driver when looking at downloads for my model on HP's site...
Anyway, inspired by this article http://forum.onmac.net/showthread.php?t=1239 I went ahead looking in the Registry and found this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0000\AD1984A\FrontShutsOffInternalSpeaker
and when I set it to REG_BINARY:00 it seems to do mostly what I want, always leaving the internal speakers on. The only little annoyance is that it it leaves the speakers on both when I plug into the headphones jack and the rear line out jack, while I would have preferred to keep the auto-shutoff feature for the headphone jack.
Best regards
Mike

Envy laptop confused about aux jack being plugged/unplugged; no sound from internal speakers

So I was typing all normal like, didn't do anything stupid or weird, but suddenly the music I was playing through my laptop's internal speakers just stopped.
And despite nothing being plugged in the auxiliary jack, the laptop thinks something IS plugged in and doesn't play sound through the internal speakers. So no sound at all.
And on the flip side, when I plug headphones in the aux jack, the laptop says that "You have just unplugged a device from the audio jack" but then plays normally through the headphones. Internal speakers still silent.
It's like the laptop suddenly got confused in whatever component registers the auxiliary connection, but I don't understand why it still plays through the headphones when it thinks there is nothing plugged in. And also why the internal speakers don't work AT ALL.
It has Beats Audio, if that helps at all. I tried restarting, messing around with the sound settings but I honestly have no idea what I'm doing and anyways nothing has changed from that.
Anyways, yeah, help?
This is a pretty new laptop, only about a month old.

Hi @nematoda
Welcome to the HP Forums!
It is a fantastic place to find answers and tips.
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I grasp that you have lost sound on the internal speakers and when you connect headphones you get the message that you disconnected the device but then plays sound through the headphones.
Here is a link to No Sound from the Speakers (Windows 8) that may help to overcome this issue.
If this has not been resolved I recommend contacting HP support for assistance as the notebook is only a month old.
Please call our technical support at 800 474 6836. If you live outside the US/Canada Region, please click the link below to get a support number for your region.

Internal speakers are not working, they're not showing up at all. Does anyone know how to fix this?

My computer's speakers are not putting out sound. They worked fine yesterday, and I just now started up my computer and began using it today. The internal speakers don't show up on my list of output devices in settings, and I can't adjust the volume. Any help is really appreciated!!!

They are all in the same folder and it says all images are there, but it is only showing 1 card's images at a time. Does anyone know how to fix this?
This is kind of confusing, on the one hand you say "it says all images are there" and then you directly contradict this by saying "it is only showing 1 card's images at a time".
Could you explain in a lot more detail what you see (and don't say "it", say exactly what part of Lightroom or what part of your operating system you are looking at), or show us a screen capture?

Problem with internal speakers of MacBook Pro

Hi,
I wanted to know if anyone have experienced a problem with internal speakers of Mac Book Pro. In my MackBook the Internal speaker volume goes down automatically. I checked the System Preferences>Sound>Output , from there I check that it is in the middle ( Balance) However, the problem is still the exists. Just for testing I played an audio file and I moved the bar toward the right speaker it is the same and when I move toward the left speaker the whole sound goes off . Looks like one speaker stops working completely. Then I checked the Utilities > Audio MIDI Setup > Configure Speakers from there I checked both left and right speakers and the channel frequency is fine. Still same issue. I have no idea what is going on , I really need your suggestions to get this fixed.
Thanks in advance.

My sound switches from internal speakers to apple Tv and i dont have an apple tv device

I am having problems with sound. My speakers will switch from internal speakers to Apple TV for no reason when I am on a certain wifi network and ask for a password. I do not have an apple TV and in order for the sound to come out on the internal speakers i have to manually go into the preferences and switch back to internal speakers. This does this constantly while i am listening to music. Is there a way to shut off the feature so it will stay on internal speakers? This has happened ever since i made the upgrade to OS mountain lion. I never did this before. Thank you for your help.

Are you sure that WIFI network doesn't have an AppleTV on it? Just because you don't own it doesn't mean there isn't one on that network. The laptop or better said the OS cannot differentiate between an AppleTV that you own or not. If it sees one on the network, it will show you one as being available. The automatic reconnection is happening probably because the last time you streamed to an AppleTV, you didn't drop that connection before sleeping the computer or shutting down iTunes.

Internal speakers will not play, only audio choice is "digital out".

15 inch MacBook Pro. Internal speakers will not play. Output to headphone plug did work. Now I cannot insert headphones into socket, it seems to be too shallow. There is no red glow as mentioned in other posts. I had the red glow issue on an older MacBook and resolved it by inserting toothpick into socket and triggered switch. I have used command, option, r and p reset. Ideas?

That is what I thought as well. I am not able to check the same headphone jack I was using earlier today, but other 3.5 mil jacks dont fit. I will try again with the same one used earlier.
Would this also cause my internal speakers to not be recognized? I had a issue similar to this with my old macbook and was able to resolve it by flipping a switch in the output socket. Something to try? I would also assume that a bent contact or switch is not something an average joe could fix.
Thanks for your quick responses.

T400 type 2768, Internal Speakers do not work? Here's what I have tried.

Hello all,
I just spent hours reading all the problems people have had with their thinkpad internal speakers not working. I bought this computer, which is past the warranty date, and am trying to fix it myself. It originally had Vista installed, and was upgraded before I bought it to windows 7. Once I updated the driver for audio, the three audio buttons began to work, but not the speakers. The headphone jack does work, however? Here is what I have done to try to fix this based on what I read on past posts in this forum:
updated windows, installed over 72 files
updated lenovo drivers for windows 7, installed 132 files. Not all applicable. Just covering my bases.
rolled back bios to default setting
uninstalled and reinstalled audio driver
updated BIOS again
installed new speakers. Old ones looked fine. No melting, pinched wires, and the inside of the laptop looked fine.
inserted headphones in and out several times to see if the audio is interupted by cutoff there. Sound was fine in headphones, but nothing happened. No noise or static or anything.
I read that this issue could be a motherboard problem? Every diagnostic I ran indicates that the sound is functioning normally. I need to know what to do next. I feel like I got took, but do really like the computer.
Can anyone help? Thanks.

If Eric's suggestion doesn't work, open System Preferences, go to "sound" and check to see of the mute button is not checked. Also check if the output name is "digital output" rather than "internal speakers" If it is, then it maybe it is the logic board, which it was in my case. However, it was covered under my warrenty. My sound problem came from a faulty logic board that was replaced in my computer for a "non boot" problem.
Good luck

How do I stream music from non-iTunes apps to Airport (mac air core-i7 OS 10.7.5 airport firmware 7.6.1 --- option-clicking speaker icon only shows internal speakers - audio streaming works from iTunes just fine.

Hello Achates:
I did not read the rather long post. If you wish to reinstall OS X 10.4, use your software install DVD. Backup is essential. To minimize your risk, I would use an archive and install:
http://docs.info.apple.com/article.html?artnum=107120
In that way, you will have a fresh copy of OS X and your current settings will be preserved.
Incidentally, I do not agree that the printer problem is best solved by reinstalling OS X. I have had HP printers for sometime and, on one occasion, had difficulty after an upgrade. HP technical support walked me through uninstalling all traces of the HP driver and then reinstalling.

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, 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. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart 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.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Is there a way to play music through the internal speakers and external speakers at the same time?

I have iHome speakers and would like to listen to my music through them and the internal speakers of my Macbook pro at the same time.
