Internal sound stopped working

My internal sound suddenly stopped working. I can still hear sound with headphones, but the internal speakers are not functioning. The trademark start-up sound (Beatles Day in the Life rip off) is the only sound that comes out of the MacBook. Within Systmem Preferences, Sound, the output tab reads "The Selected Device Has No Output Controls." And within Utilities, Audio MIDI Setup, Audio Devises, the Built In Input Devise is active, but the box reads that "Output Is Not Suportted." Also when I try to adjust the volume with my F10, F11 and F12 keys, the Speaker Icon is in grey, all the audio bars are in whilte and there is the small circle with line throuh it below, that would indicate mute or no sound. Looking for direction to resolve the problem. Thanks.

This also worked for me. Red light on, put in jack, wiggle, pull out jack, red light gone, volume controls and sound work again. Thanks.

The sound stopped working on Mac Book Pro OS X?

The sound stopped working. Firefox installed updates and since, the sound is disactivated. I went to preference, and the silence box is checked, but it doesn't allow me to uncheck it. The sound peripheric is not recognised it seems. What can I do?

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Make sure Mute is not enabled.
2. 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.
    Option click the speaker icon, if present and select Internal Speakers.
6. Launch iTunes and play a song. Adjust the volume there.
Best.

Internal microphone stopped working today - Pavilion G7 - C2M31UA#ABA / Windows 8

Hey there
I am using Skype quite often, but today my internal microphone stopped working. I restarted Skype, my laptop and I also followed all steps of you trouble shooting page. No change ...
Any ideas?
Thanks

Enter your device manager.
Can be found by pressing windowskey + x.
Press Sound, video and game controllers.
And right click and remove the one called Realtek high definition (should be something like that).
Reboot the computer, this should make it reinstalll the driver på itself.
If this doesn't work, search for the program called recovery manager. In here you pick the one furthest to the left, called something with reinstall driver. Here you find the one called IDT High-Definition (HD) Audio Driver check it, and press install.
Since it used to work, and you dont have windows 8.1. If this still doesn't fix it, it must be some setting regarding your microphone. So try right clicking your speaker icon down in the right corner, when in desktop mode and pick recording units (translating directly from danish). Please let me know what you see in here.
Best regards

Troubleshooting Steps:
1. Reinstall Adobe Reader.
2. Turn it off and on.
3. Press Kudos star.

Internal mic stopped working today, please help! C660 1F1

Hey guys,
My laptop is a Satellite C660 1F1, and it runs Windows 7, 64bit version.
This afternoon, my internal mic stopped working. It was just fine this morning. Yet I can still hear people on Skype perfectly.
I've checked all my settings, and according to them, everything is just fine. But it isn't. The little green bar that shows received sound doesn't move at all. It only moves a tiny bit when I tap the mic with my finger.
I've reinstalled drivers, I have my settings adjusted for maximum mic usage, but it's just not working.
I don't know what else to do, and this mic is the only way I can contact my family right now. Someone, please help me!

Regarding Facetime on my Ipad. I get started on a call and after 10 or 15 minutes I cannot hear whom I am talking to. They can still hear me and I still have picture on the screen but my sound stops working.

My sound stopped working on my HP dv6-1280us

Its only a couple of months old but my sound stopped working. I don't know much about laptops but here is what I do know.
It stopped working around 10 days ago. At first there was no sound but I could move the volume up and down with the quicklaunch pad and the mute button would go from red to blue when touched. I checked to make sure nothing was muted and everything seemed to be fine.
I googled the problem and it said to do a system restoration back before it stopped working. I tried several times and it went through the process but then when it rebooted it said that it didn't work and that none of the settings have worked.
Then a couple of hours ago I noticed the mute button is now red and won't change to blue the volume slider is not responding to touch either.
Then I saw a post on here that said to go to system recovery and reinstall the sound drived (IDT High Definition CODEC) and I did and it said it did but it didn't fix the problem.
I am lost and would love some help if anyone has any ideas? please?
Thanks
Amy

I got some help from a friend and her advice worked. I thought I would post this for others having trouble
Well I guess you could try this it would not hurt. Assuming you use Windows that is.
Go to run and type services.msc when the box pops up scroll down to Windows Audio and double click. Make sure that the service is started.

I updated my ipad and the sound stopped working.

I updated my ipad to IOS 8.1.and the sound stopped working. My sidebar buttons say soundeffects or soundeffects mute when I press them. On my control panel there is no sound bar. As you can see in this screenshot it is not showing a sound bar to adjust volume. HELP?!

Update: Last night, I cleaned my headphone port & docking port. Reset Network Settings & General Reset all settings & reset ipad. Didn't work immediately & had some setbacks. I decided to wait to do the restore factory default for the next day, this morning. I decided to test the sound before proceeding. My sound is working correctly now & didn't need to resort to the restore factory default. All of the above worked but perhaps needed over night to really dry the rubbing alcohol used to clean the ports.?
sound is working. Thanks so much for your help Diavonex!

Hello everyone my iPhone 5s sounds stop working.i did not do anything it just stop working when I tried to turn on my music player all the sounds is not working I already check the volume and it is not also muted :( what happened can anyone solve my problem please

Hey Kirby17,
Thanks for using Apple Support Communities.
If you are not getting any sound from the speaker, follow this article.
iPhone: No sound or distorted sound from speaker
http://support.apple.com/kb/ts5180
Ensure that there is nothing plugged in to the headset jack or the dock connector.
If the iPhone is in a protective case, make sure that the speaker port isn't blocked by the case.
Make sure that the speaker and dock port aren't clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush. Carefully and gently brush away any debris.
If an audio issue occurs when using a specific application, try testing other applications to see if the issue persists.
If the iPhone is paired with a Bluetooth headset or car kit:
Try turning off Bluetooth.
If you experience difficulties with the Bluetooth feature, follow these troubleshooting steps.
Restart the iPhone.
If restarting doesn't fix the issue, ensure that your iPhone is updated to the latest version of iOS.
If the issue is not resolved, please contact Apple Support.
Have a nice day,
Mario

Iphone sound stopped working after ios 6.0 update

My 4s was working fine until I updated to 6.0. After that, my sound stopped working. If I plug in headphones it works, but as soon as I unplug it stops. When I plug into my USB sync cable it works, but when I unplug it stops working. I updated through user settings over wifi and not through itunes sync if that makes any difference. I know other people are experiencing similar problems. Any help would be appreciated.

Yes rev, I tried the dock cleaning as well, I didn't help me either. I read and tried everything others did-no luck. I'm guessing these are the facts, either it will quietly get fixed on an update or the % of phones with the problem compared to those that don't doesn't warrant attention and is better addressed through Apple by just replacing it..if it's still under warranty.

My internal microphone stopped working on my imac?

My internal microphone stopped working on my imac? I only noticed when I tried to use Skype. It was fine till a recent change to hard drive after a mechanical failure and a clean reinstall. I have USB headset and it works fine, in and out. Any answers/suggestions would be much appreciated.

Check your settings in System Preferences>Audio and make sure that internal microphone is selected on the input tab.

KM2M + WIN XP sound stops working after a few minutes

as in subject i have a KM2M COMBO-L (MS 6738) MoBo with athlon xp 2000+ and 128 MB spectek PC2100.
The problem is that the sound stops working after some minutes of use.
It's the same problem in all the 10 PCs of my webcafe

KM2M uses the Realtek ALC650 CODEC. Are you using the VIA Audio driver or Realtek? It should say under audio properties.
I recommend the Realtek drivers.
Of course, if you are already using the Realtek, then I recommend the VIA drivers.
Pretty insightful, eh?

OS updated - Sounds stops working

I updated my 2013 (Late model 2012) Mac Mini to the most recent version of the OS Mountain Lion this past weekend - now after about a day of use - the sounds stops working. It is connected via the Thunderport to Displayport on a Dell Monitor. Has always worked fine until the software update this past weekend. Once I reboot - it starts working again and then a day later stops working and I have to reboot! Any thoughts!
Thanks as this seems directly related to the upgrade!

Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Alert sounds stopped working

My email, WWF, etc. alert sounds stopped working on my Ipad2, suddenly, for no reason. I tried resetting the system 3 times and that did not hellp. The OS is up to date. The do work if I 'test' them, though. And, my sound works fine on videos, etc.
Any suggestions? It is past the warranty period

Have you got notifications muted ? Only notifications (including games) get muted, so the Music and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085
