The volume on my Macbook Pro is not working ?

I've checked the settings in System Preferences and it seems everything should be working with my volume. NO GO! Help please

Is it not working across the board, or on very specific things (like You Tube videos)? The reason I ask is because there is a separate volume control on You Tube videos that must be turned up in order for you to have volume.
I couldn't figure out why none of the You Tube videos I was attempting to play didn't have any sound until I discovered this....It's in the bottom left-hand corner of the You Tube screen.
Just wanted to share!
Cheers,
GB

Output volume on my MacBook Pro is not working

My output volume on my MacBook Pro is not working. When I go to "Settings", then "Sounds", then "Output", I can not slide the volume bar at all, or change it in the menu bar?

See if a PRAM reset will solve the problem;

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.

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.
HELP!!

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    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 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".
4. 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.

One of the key on my macbook pro is not working properly, can it be fixed by a cleaning spray or something. there is lot of dust in where I live and thought that might be the culprit. thanks Jason

Don't use any cleaning spray. Wipe with a moist but not wet microfiber cloth.

The Volume on my Mac pro is not working. I can't raise or lower the volume and sometimes it mutes by itself. additionally, the speaker button on the top right is garbed out.

One of the USB ports on MacBook Pro does not work.

Hi,
I purchased a MacBook Pro in Jan '11. Both the USB ports on the laptop were working fine. Recently, I have noticed, any external device connected to the USB port, towards the battery side does not recognize the connection.
Any solutions ?. Is this defect covered under warranty ?.
Regards
Anil Madan

Anil,
Try resetting the SMC.

Release all the keys and the power button at the same time.

So in the last few days I’ve noticed that pressing my volume change keys actually isn’t changing the volume on my macbook pro at all. When I press the volume up or down keys, it makes the recognisable pop sound but stays at the same volume while the squares go up or down. I mute it but my computer still makes sound. It’s the same with the volume control up the top of the screen, too. I slide it up and down and it doesn’t change the volume at all. The only way I can change the volume is with my speakers or the program I’m in (iTunes, VLC etc). I restarted and it seems to be okay then I go to change it a couple minutes later and it’s back to not working again.
I’ve checked my settings- the “use all F1, F2, etc. keys as standard fuction keys” is not switched on, and I have tried a suggestion of moving the com.apple.systempreferences.plist file out of the library and onto the desktop and restarting and neither of those seem to make any difference whatsoever. I’ve tried to find online forums but the only suggestions I found were those two and they didn’t work.
I’m just annoyed because I usually have the worst luck with technology but my macbook had been going strong and I got it because of the apparent lack of things that could go wrong, but of course even if there is one thing that could go wrong it will happen to me.
Please help!

You migh give resetting your NVRAM a try:

Why is the volume on my MacBook Pro suddenly so low?

The volume on my macbook pro is really low. It used to be much better, now I can hardly hear people when on skype or listening to music... everything is set on high volume... help!?!

Try:
Reboot into Safe Mode then reboot normally. Safe mode takes longer to boot than booting regularly. That is normal.
Intel-based Macs: Resetting the System Management Controller (SMC)

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
