Macbook pro doesn't recognize internal speakers

my macbook pro doesn't recognize internal speakers and there is a red light inside the headphone port. How can I get the speakers working again?

In addition to what dominc23 suggests, you may try jiggling a toothpick or cocktail stirrer in order to trip the internal switch. If all fails, the Apple store genius bar is you last resort.

Macbook Pro doesn't recognize audio cd's after Yosemite upgrade

After completing the upgrade to Yosemite, my Macbook Pro doesn't recognize purchased audio cd's. Help!!

hi russeel!
when i first upgraded to 5.0.1.4 i panicked for a while looking for that tab (and the Burning one) ... the subtab that i find kind of strange is "Advanced-General". Generally Advanced? Not Tremendously Advanced?
okay, we've gone up a
b lot
of versions in your case (nearly as many as it is possible to go), so we'd probably better check through some of the usual suspects. let's start off with this document:

Macbook Pro doesn't recognize Flip Mino camera in USB port after Yosemite upgrade

Since I upgraded to Yosemite, my Macbook Pro doesn't recognize my Flip Mino camera in the USB port.

I don't use FLIP, but if you get no other help here,
consider the following ideas.
If neither restarting your Mac
nor reinstalling OS X fixes your
problem, you might find some
help if you search or post in the
CISCO forum where Flip users post.

Macbook pro doesn't recognize camera on image capture

My MacBook Pro doesn't recognize the built-in camera for a lot of my applications, including Image Capture. It doesn't show up anywhere in my system preferences. Any idea why this is so?

(1) Mac's built-in camera does not work with Image Capture.
Image Capture works with external devices like scanners, some iOS devices, some cameras and RAM cards, etc. Click this link for more info about Image capture and some of the apps that can work with your inbuilt camera.
Click here for info about how to use Image Capture to transfer images from a connected external camera.
For more info about Image Capture functions, see Image Capture > Help on your Mac or the Apple pages in this link.
(2) To test for application-specific problems mentioned in the "How to Troubleshoot iSight " article, use apps like Photo Booth, QuickTime Player, iChat, FaceTime, or others intended to work with your Mac's inbuilt camera.
(3) To test for user-specific problems mentioned in http://support.apple.com/kb/HT2090 the "How to Troubleshoot iSight " article, you must have more than one user account. Do NOT use the "Guest" account. Click this link if you need help creating new accounts for testing.

Macbook Pro doesn't recognize iPhone 4Gs

Macbook Pro doesn't recognize my iPhone 4Gs
My Macbook Pro 15 (Mac OS X 10.6.8) doesn't recognize my iPhone 4Gs (iOS5.1)
Suddenly it stopped, last time was April 11 via Wi-Fi.
Now even with the device plugged it can't be recognized.
On iPhone Settings, the "iTunes Wi-Fi Sync" tab is grayed.
Few days ago iPhone started to behave strangely, refusing to power off, sometimes not charging when plugged to USB port, sometimes does.
Don't know what to do.
Thanks in advance
best

What kind of phone is this? an iphone 4? or an iphone 4S? ( note there is no such phone as an iPhone 4gS)
What you describe here is in my eyes the beginning signs of accidental damge, such as water damge of some sort.
This is a great oppurtunity to see if the same issues you are having when connecting to your computer, replicate when conencted to another computer.
You need to find out if there is a way to test with a new USB cord if possible to rule that out.
Trying to isolate this to, or away from the iphone.

HT5172 My new Macbook Pro doesn't recognize my card reader (with a CF card inserted).

My new Macbook Pro doesn't recognize my USB card reader with a CF card inserted. It works fine on my old Macbook Pro.
Do I need a new card reader? USB 3 perhaps?
I would appreciate any input that you may have. Thank you.

Hi, closereaching. Instead of spending 12 hours reinstalling your operating system and getting everything back up to date again, which probably won't accomplish anything, why not buy a $10 USB card reader for your Casio's SD card? Or (more expensive, but a much more elegant solution), an ExpressCard SD card reader that can stay in your computer all the time?

Macbook Pro doesn't recognize DVD

My MacBook Pro doesn't read some DVD's! I'm trying to install my camera's software, but the drive doesn't read the DVD! It just make some odd noises and then ejects the disc. However, it can still read discs I burned on my other Mac and it recognizes blank CD's and DVD's! Is anyone going through the same issue?

It's the DVD for Mac. And I'm having the same problem with other DVDs. The drive just recognize blank discs and discs burned on other macs.

MacBook Pro doesn't recognize iPhone when USB connected

I have a MacBook Pro, an iPod, and an iPhone. Using the same usb port and cable I have the following situation. The MacBook Pro recognizes both other devises in iTunes through the internet. The MacBook Pro does not recognize the iPhone 5 when connected by cable but does recognize the iPod. Because of this I can't transfer photos from the iPhone to the MacBook Pro. When connected the iPod shows it is charging but the iPhone 5 does not. Using the same cable connected to the wall charger both devices show they are charging. Does anyone have a suggestion? Thank you.

Not Charge

MacBook Pro will not recognize internal hdd

my macbook pro MB991LL/A 13" 2.53 ghz will not recognize the internal hdd, but when external boot drive is connected it will boot. ive tried two diff internal hdd and the same problem with both of them. i want to upgrade to an internal ssd but im not sure that its the drivee. any ideas on what the problem could be?

My hard drive is now connected. But Time Machine will not let me select the hard drive as my back up drive. This hard drive was used on another Macbook, so Time Machine doesn't seem to recognize the hard drive on the new one. Do I need to reformat the hard drive? I hate to do that because I have the previous backups on there.

Macbook Pro no sound from internal speakers or headphones

I have a macbook pro (mavericks). There is no audio coming from the internal speakers and when headphones are plugged in there is still no sound. There is no red light coming from the headphone port either. Any advice?

Try plugging the headphones in and out 10-12times, while toggling the volume and mute buttons.
Have you tried cutting the end off a cotton swab and GENTLTLY swabbing the the headphone swabbing the port 9;00 clock to 3:00 clock, there is a micorswitch that some times gets "hung up" and this can free up the witch.
Also you can try going to to applications/utilities/ Audio MIDI Set up. app and see if you can select built in there.
To get more aggressive you can try these options:
Close all windows and quit all applications.
Click "Go" menu in the Finder menubar.
Select Computer, then Macintosh HD > Library > Preferences
Open "Audio" folder.
Right click these two files and select "Move to Trash".
com.apple.audio.DevicesSettings.plist
com.apple.audio.SystemSettings.plist
Close the window. Restart the computer
Go to Applications/Utilities/Audio MIDI Setup/Built-In Output/Output and in Format change from the default 2ch-24bit integer to any other format (say, 2ch-32bit float). This should activate the headphone jack. I moved the format back to the original 2ch-24 integer setting and the headphones continued working. So it seems that (for some reason) the original default setting does not recognize a headphone being inserted, but after performing this "resetting" it seems to come to its senses and behave properly from then on
if these do help your issues, please post back, there may be other options.
It is best to start a new post, rather adding on to an already existsting, as you will get more people looking at it, and thus offering more advice/sugestions.

Macbook Pro doesn't recognize my fast track pro c400

Hello I am using Fast track pro c400 from M-audio.
When I use the fast track pro c400 it works.
However, when I disconnect it from my Macbook Pro and reconnects it,
MIDI setting recognizes it again but this time with out any available input and output.
So when I use mainstage or garageband, it recognizes that there is 1 midi input but
when I go to setting it doesn't uses fast track pro's input, output instead, it uses built in I/O.
So i tried to reinstall my driver and when I did it, it worked again for few time and
same problem occured.

okay, I had connected my MBP to the base station and managed to restore the base station to factory settings. So, my MBP recognized the base station, although there's something weird about it.. you know how when you open the airport utility, on the left hand column, usually there should be a picture of your airport extreme with the name below it, right? Mine doesn't show any picture except the orange dot and my base station name.
In addition, my MBP airport is able to pick up my recently-made network, but unable to join the network. Again, when I opened the AirPort utility, it can't detect my airport extreme wirelessly.
I have tried every method that I can think of, but my MBP won't recognize the airport extreme anymore, wirelessly.
Please tell me what should I do?

I have tested all three HDMI inputs which work with other items but the Macbook doesn't ween to recognize I am connected to this TV like it does with my other TVs.
Any ideas?

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.
Jason Miller

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)

Macbook Pro - No Sound from internal speakers + No red light

Okay so I know this a very famous issue (I've seen over a hundred threads with people having the same problem) but the problem I'm having is something I haven't seen anywhere else. I recently tried to fix my headphone jack on my Macbook pro early 2008 model when it DID have a red light emanating from it but when I finally managed to turn it off with a little wiggle from my paperclip the sound still didn't turn back on. In my system prefs my sound output still displays "Digital Out" and no other option for internal speakers. I know my speakers are fine because I can hear the startup chime. Also, I had a broken piece from my headphones stuck inside the jack a few years back and I retrieved it in....let's just say, not the most professional way to do it (I completely destroyed my headphone jack while attempting to retrieve the broken piece and now the hole is too wide for any headphones), though afterwards the internal speakers still worked for a while, it was just the headphone jack that was messed up.
Basically what I'm trying to say is: is there a way to enable my internal speakers without using any hardware methods? Because I tried the paperclip fix and the red light did turn off, but still no audio + sound prefs still shows 'digital out'. I really don't care much for the headphones jack anymore because I'll just override it with some USB headphones.
Thanks in advance

I agree Nick - it is a concern especially on such a basic function (sound) - Linc is right, the issue is microswitch, sounds like a bad design or a huge batch of sub quality switches, checking the forums this issue is common on MBP's.
Judging by the date and lack of further activity I assume you managed to get yours fixed at the genius bar ?
I finally fixed mine myself but posting reply for others who have same issue as this - however buyer beware folks, try this at your own risk !!!
The fix won't be liked by Apple Support, the genius bar, or the repair shops but it worked for me after over 12 months of using headphones / external speakers - WHAT A PIA !
Method -
Held Macbookpro on it's side with screen open and headphone/ audio port facing toward ground.
Took WD40 can with straw dispenser and placed straw inside audio port - sprayed 3 or 4 one second burst of WD40 into port.
Held MBP that way for 30 seconds giving MBP a shake to drain WD40 out
(I performed this whole excercise outside where the WD40 could drain out without an issue ;-)
I then took an old set of headphones and re-inserted / removed them from the audio port approx 20 times in and out with music playing on the MBP - intially when inserted music will only come from headphones then eventually MBP internal speakers start working !
I've tried everything else including the cocktail stick and bent pin inserted inside the port to try and free micro switch - nothing worked it was stuck fast.
As stated, can't endorse this for anybody else - you do so at your own risk - just stating this is what I did to get mine working again !

HT2494 2012 MacBook Pro - no sound from internal speakers, red light in headphone port

Mid 2012 MacBook Pro 15".
I normally use external speakers plugged into headphone jack.
The other day I unplugged the external speakers and when I re-booted my Mac, I got the start up sound
but I have no sound coming from my internal speakers. In System preferences sound output I see no entry for internal speakers.
I also notice a red light shining in the headphone jack port. I see on youtube that this problem is rather widespread.
Some suggest using a paper clip to try to turn the light out, but I am not doing that.
I have Lion installed, tried using the MIDI-app to reconfigure the speakers, but I only get sound if the headphones are plugged in.
Is this a software or hardware problem?
I have a genius bar appointment today at my local Apple retail store, and my mac is still on warranty but this
is troubling that you spend $2300 for a laptop and after a bit of regular use the internal speakers no longer work.
Any ideas?
thanks.
