I don't have any sound on my Mac Book Pro.

My volume bar appears as if my computer has full volume, but I can't hear anything, not even the "Bleep" the sound does when you push the sound buttons.

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.

I'm not getting any sound on my Mac Book Pro.

Can anyone suggest a fix for my sound problem? I've tried everything that I know about.

I've tried everything that I know about.
And what it is, that you tried?
Have you checked the "sound" System preferences? Is the output set to "internal Speakers"? And the volume turned up?
Sometimes it will help to plug-in headphones or external speakers. This can solve problems with the contacts in the "line in" or headphone port. After connecting something to Line-in or headphone port and removing it again, sometimes the internal speakers will work again.

thanks!

I'm sorry.
If you were looking for help, I assume you would have told us about your sound card, how your system is configured, whether you are using a desktop/window manager, which one, the articles in the wiki you have researched, and what you have tried.
Edit: I'm apparently in a bad mood. I'm going to go outside and do some yard work. It is a beautiful 75 degree F day here in So Cal

the sound is put to maximum position

Check the function keys again. If there is no change, try a PRAM reset:

I don't have any sound coming from my speakers after updating my HP Envy H8-1513C?????

Since I updated my HP Envy H8-1513C i don't have any sounds coming from my monitors. I also can't seem to get any sync cords for my iphone 4 to work with my computer. These always worked before the update???

I recommend going through the troubleshooting section in this document to see if any of that can resolve your issue.
Have you tried a hard reset yet?

Do you have sound coming from the audio output port using headphones? If so, when the plug is pulled out, is there a red light?
You may need a PRAM reset:

I don't have sound on my Mac Book Pro...

I don't have sound on my Mac Book Pro... I've gone to my sound in the system prefrences and it's saying that internal and export sound are not even an option.

Hi j,
Have you tried a pair of ear phones yet? If not, try it.
If no luck, gently pull them out and push them in a few times.
If no luck, try the following:

I have an Apple iphone 4s and for the last 4 weeks I cannot download or update any apps. I have an iPad and a Mac book pro and the apps download on these devices fine. My phone tells me that I have 12 updates but when I press update all or update any individually nothing happens at all. It also does not ask me for my password any more but my iPad and mac book do.
I have signed in and out of the app store and the password is correct. I have tried both kinds of reboot but that did nothing. I have tried to update the apps by connecting phone to Mac book pro...it shows the apps being download on the Mac book and says it will sync them to my phone but it does not. Everything else on my phone works fine.
Any ideas ...Please!

Thank you, this has resolved both the iphone and ipad problem immediately. I am concerned that I may have a problem with apps that I bought under my old AppleID as they will not be recognised. Any suggestions for this please?

I have just bought a new Mac book pro and I want to transfer my iTunes (including music, photos and apps on my iPod touch) from my old windows computer to the Mac... any tips?

many thanks Carl.

You must boot from another drive in order to erase the system drive.
Try starting up with Snow Leopard DVD inserted and C depress. That should get you booted from the DVD. Then start Disk Utitlity from DVD and erase the disk then you should be able to install Snow Leopard.
Remember that everything will be removed from the disk when you erase it and install Snow Leopard so backup first.

I have a issue with my mac book pro. For some reason it won't stay powered on. I can't get past the apple loading logo. The battery is fully charged so it is not the problem. Can anyone tell me what the problem may be and how can i get it resolved?

What happens when you use the MagSafe?

Hello, I have a problem with my mac book pro after running the battery dead on a game. The display has shrunk leaving two black margins on either side. What to do ?

Go to System Preferences>Displays and set the resolution to "Best for this computer" (or something to that effect).

When trying to download Mavericks it says it cannot be loaded onto this machine? Strange as I have just downloaded Pages, Numbers and Keynote...free? Thanks and Regards

Welcome to Apple Support Communities
You already have got OS X Mavericks installed (the Keynote, Pages and Numbers versions available in the Mac App Store are only compatible with OS X Mavericks).
You have got a Late 2013 MacBook Pro, which uses a special OS X Mavericks version that is not available in the Mac App Store. This is the reason why the Mac App Store is not compatible with OS X Mavericks even if you are using it. This will be fixed in OS X 10.9.1, when your Mac uses the same Mavericks version as all other Macs.
Until then, you can reinstall OS X through OS X Recovery > http://support.apple.com/kb/HT4718
