The sound on my Macbook doesn't work.

The sound of my MacBook Pro 15" Retina just works at the startup screen. I can control the volume on startup screen but when I login I can't hear any sound from my MacBook even I plug headphones or speakers in.

Go step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers.
    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.

What generation MacBook Air? You might start here:
https://discussions.apple.com/thread/1736638?start=0&tstart=0
Apple will fix it. No pricing without making an appointment with the Genius Bar at the Apple Store. Usually an Authorized Apple Repair Store can do it with a faster turn around time and less expensive pricing.

Why does the sound to my MacBook Air stop working after it wakes up from sleeping?

When I leave my headphones in the headphone jack and then close the computer to sleep, when it wakes back up the sound will not work.
It doesn't work with the headphones in or out, it is just completely disabled. I tried muting and unmuting and and toggling the volume but the only thing that works is restarting the computer.
Obviously, the sound works after restart but it is an inconvenience due to the tone on restart which is not the greatest noise when trying to work with a sleeping baby in the house (Which is why I use headphones in the first place.)
Any help is much appreciated.

Plug in the headphone and remove it

The sound on my mac doesn't work anymore, neither with headphones nor without them.

Can anyone please tell me how I can fix the sound on my mac? It stopped working completely as if it were on mute, yet the computer tells me the sound is on. Thank you in advance!

I found the solution, I just turned off my mac and the sound came back.

The sound on my iPad2 doesn't work, only the headphone jack

There is no sound coming out of my iPad, only if I use headphones, and when I adjust the volume it says "headphones" even if I dont have them in

Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.
With IOS-5, hold until the screen blanks. The Apple logo appears after you let go of the buttons.

Hi Kappy Thanks for your answer. I did a reboot on my Macbook as suggested and this operation is going on non stop for 14 hours and on the screen always appears the same message that you can see in the picture in attachment. Any ideas?

The sound on my macbook pro is not working

The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.

The Sound On My MacBook Pro Isn't Working

The sound on my MacBook Pro is usually fine, but today it didn't work. For example, I tried listening to music on iTunes and watch videos but the volume wouldn't work at all. When I go to turn up the volume, it seems to turn up ok, but when I try to put on some music, it doesn't work at all. I then tried using my brother's Apple headphones on my MacBook Pro, and then the sound worked normally. I really would like this fixed so if someone could help me that would be great, because I don't want to keep using my brother's headphones just to watch a video or listen to music. Thank you to anyone who helps!

Hey
I did a NVRAM reset, and nothing happened. The sound stayed the same. Whats an audio output port, where can you find it, and where can you find the red light? When I try turning up the volume, instead of turning it up a cross sign appears under the speaker, thus no volume turns up. The menu bar right at the top of the screen - the speaker icon is not black, but more a very light grey.
Thanks for helping though!

The sound on my Macbook Pro does not work.

The sound on my Macbook Pro does not work. When we press the volume buttons, the sound icon pops up, but the bar is full with a small "Does not work" circle below it, and nothing happens when I hit volume up or done. I went into system preferences, but there aren't any options there that I can see to change it.

"Unfortunately, it doesn't provide any help for a MacBook Pro, other than indicating to call Apple Support" (sic).
Au contraire. TS1574's title and affected products are thusly:
"Troubleshooting issues with no audio from built-in speakers on Macs
Products Affected Mac mini, MacBook, MacBook Pro, iMac"
As a result, the instructions of the article are relevant. To be sure, follow those steps, the last of which is to contact Apple.
So, by way of reminder, here are the steps to troubleshoot the audio on your MacBook Pro. There is no red light, so the port is likely fine. Headphones work, so clearly your sound card is fine.
1. Ensure an incorrect version of OS X is not installed. If one is, then reinstall or erase/install after backing up your data.
2. Remove any external audio devices from USB, firewire, etc.
3. Open Sys Prefs > Sound > Output
If Internal Speakers is listed, select it and test again.
If Digital Out is listed, confirm again that all external audio devices and cables have been removed.
If mute is selected, unselect it.
If the volume slider is low, raise the volume.
If the above simply doesn't fix it, the issue may be a corrupted plist. Apple Support might be able to help troubleshoot the issue further, per the last step of TS1574.
I hope it gets resolved for you. Good luck.

How do i copy content from one hard rive to another through my macbook air? the copy and paste option doesn't work

How do i copy content from one hard rive to another through my macbook air? the copy and paste option doesn't work

It's because of the extension of the hard drive is a Windows extension ( most likely MSDOS or Ex-FAT), meaning you can only read but not write. If there are no important files (or you can copy the whole thing to your computer/mac) you can just reformat the hard drive and change the extension to NTFS (readable and writable on both windows and mac) or Mac OS Extended (readable and writable on Mac, readable on windows).
Go to DISK UTILITY
Choose the Hard Disk you intended
ERASE
You can choose either
(I personally prefer this one, you know just in case)

Are you running Snow Leopard or Lion? Your info says Snow Leopard. If it's lion then:
In Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
Then you can locate the folders mentioned.

The only time the sound/speaker and mic don't work is when I answer or make a call

The only time the sound/speaker and mic don't work is when I answer or make a call. They both work fine for everything else. This has been going on for over a month. AT&T said it's Apple and Apple said it's AT&T. I've been around that cycle twice.
When I dial a call, I can see the status words on the screen but can't hear the ringing. If the person I'm calling answers, my screen will show the call was connected and the call timer will begin but I can't hear anything and they can't hear me. If one of us doesn't end the call, the timer keeps going and I'm being 'charged' for dead air. (Of course, one of us disconnects so mins/cost isn't an issue, I'm just adding the info in case it helps solve the problem.) If they don't answer, the call will go to their greeting but I can't hear it and wouldn't be able to leave a message anyway because my voice isn't going through. However, they will get a voice mail alert and see that I called but no message was recorded.
If some one tries to call me they will hear ringing but when I answer, they can't hear me and I can't hear them. If I don't answer, they will hear my greeting and can leave a message. I can retrieve and hear my voice mail. Trying speaker phone and headsets didn't change anything for calls out nor for calls in.
I have 4.3.3 and have synched, reset, rebooted, turned things on and off and off and on and took the SIM card out of the phone and out of it's tray and put it back in. I've done all that several times in just about every combination and order possible.
Hopefully the following will provide good clues: On only about three of the many attempts I've made to get it to work correctly that included taking out the SIM card, I could make and/or get one or two calls with no trouble but then the problem comes back. Also, when I swapped the SIM card with another iPhone4 on my plan, the other phone would work with my SIM card but my phone still would not work with the other SIM card. The last fact makes me think it is an Apple issue. I'll go to an Apple store (genius) this weekend. Will I be wasting my time and gas? Anybody have any experience with this problem?

Let me try and address some of your questions. I'm only on a pc, so a few of these answers might be slightly different on a Mac, but not too different (such as control click rather than right click).
First, when you buy something on your phone, be it apps or music, it's transferred from your phone to your Mac when you sync your phone. So those apps should now be in you iTunes library. ( IF for some reason you can't find them there, you should be able to download them again, either onto your phone or through iTunes. On your phone, go to the App Store > Updates and you'll see a "Purchased" link at the top of the page, you can view all purchased apps here and redownload them. In iTunes, you can go to Store > Check for available downloads. )
Whenever you plug your phone in, it should create a backup of everything you have on the phone. This is how, provided restoring your phone as a new device doesn't fix the issue (more on this later), you can put all of your music and apps onto the new phone. You can always plug your phone into your Mac and the first thing it should do when it syncs is create a backup. If you want to be sure, you can right click on your device in iTunes (on a pc) or I assume control click on a Mac and select "backup".
The genius will take care of the sim card and setting up your phone, however you will have to put all of your music and apps on it, unless you ask the genius, I've never bothered since I know how to do this.
You should have no problems restoring from a backup if they give you a new phone. However, it's probably safest to try and create a backup of your last phone backup before you restore it as a new device. I suggest you refer to http://support.apple.com/kb/ht1414 for more information about that.
I've had no problems with my new phone so far.
I'll try to keep checking this thread if you have any other questions or need more clarification.
Edit: I should say we never did figure out what exactly was wrong with my phone. The only thing I can think of was that it got a lot hotter than the phone it replaced, and also the phone I just got yesterday to replace the malfunctioning one. But otherwise they saw no problems with the hardware, but acknowledged it must have been the hardware since we tried everything else. Also I would go with a list of all the things you tried with this phone, for your own reference and the genius's, especially if you're not confident in your tech skills Showing the genius that you've tried: different sim cards, updating the software, restoring it from a backup, and now restoring it as a new device, should convince them that you've done everything you could, and the only other answer is hardware problem.
Also if you don't already have one, make a genius appointment ASAP. Most stores are very busy and their appointments fill up fast. I always suggest making an appointment as early as possible, hopefully before the retail store hours when they've only got techs there because they usually are less stressed and have a bit more time to spend with you. The easiest way to make an appointment is to download the Apple Store app. It detects the closest Apple store from you and makes it quite easy to schedule a genius.

When I use my remote to start a movie on iTV it starts a different movie on my MacBook, plus if I use the arrow up or down on my remote it adjusts the sound on my MacBook. How do I stop this?

I am using 2nd generation Apple TV and have a MacBook Pro. When I use my remote to start a movie on iTV a different movie starts on my MacBook. Also when I use the up and down arrows on the remote it adjusts the sound on my MacBook. Is this something I have to live with, or is there something I can do so the remote control doesn't affect my laptop?

Well, I feel sheepish. I found the answer. Thank you Apple Community!!!

Since updating to 706 the sound on my ipad2 is not working right. On videos or music. There is constant distortion and what sounds like interference. Any ideas?

Since updating to 706 the sound on my ipad2 is not working right--on videos or music. There is distortion and some kind of interference at all times. Any ideas?

Has the unit EVER been jailbroke?
If "No," first try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, if you have IOS-7, read this.
