My volume is disabled on macbook pro OS 10.8.2

I don't know why, and I can't figure it out how to fix, but my volume is "disabled". I have logged out/rebooted/etc., but to no avail.

Two standard things to try.
(1) Plug/unplug a headphone into the headphone ports. Occasionally they get stuck.
(2) reset the PRAM

The volume keys on my MacBook Pro stop working after using headphones.

The volume keys on my MacBook Pro recently stopped controling the volume after I've used headphones. I still have sound; I just can't make the volume increase or decrease. The mute, however, still works just fine. Because I have sound from the intenral speakers I know the computer doesn't think the headphones are still in the jack. A reboot fixes the problem, but as soon as I use headphones the problem starts up again. I want to fix this permanently.
I don't know if this helps but all the other keys (brightness, play/pause, etc) still work. I recently had to reset the PRAM because my computer refused to sleep when the lid was shut. I've checked system preferences and everything seems to be in order.
Can someone please help!?

I found this advice on another thread after encountering the same problem - I did the reboot and it worked fine and dandy!
I spoke with Applecare to fix my Macbook volume. Apparently there are pins inside the speaker/headphone jack that can get jammed. We fixed mine by doing some sort of reboot:
Turn off laptop.
Hold down the Option, Command, P, and R keys (all four at once, it's tricky!) and while holding down the four keys, turn on the computer. When you hear the second chime, release the four keys.
This re-set the sound toggle to internal speakers. Now I'm afraid to insert headphones again, but I assume this reboot will work over and over.

There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator.

There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator. However, when i lower it, my safari tab goes out of the screen. What do you guys think i should do? I'm getting very nervous.

hey HAbrakian!
You may want to try using the information in this article to adjust the behavior of your function keys to see if that resolves the behavior:

The volume control on my MacBook Pro (running Lion) is not working

All of a sudden I lost the ability to move the volume slider for my MacBook Pro internal speakers. It's permanently set to mute. I can't figure out! Every time I go into System Preferences and click "Sound" I get the spinning beach ball of death and crash out. Every time! Don't know where to go from here. Maybe my problem is bigger than the audio thing, but everything seems relatively ormal aside from this.
If anyone has any insights, I'd really appreciate it!
Thanks

I sggest you reset the PRAM:

Reboot the TC.. Sometimes you need to reboot the whole network.
This is what comes of Lion and then made worse in Mountain Lion of Apple not spending enough time to fix the bugs.
Read C12 in pondini.

C17 can be related I think.

HT3275 Time machine cannot backup due to "The backup disk image "/Volume/Data/Dave's Macbook Pro."sparse bundle" is already in use." Does anyone know what this means and how to fix it??

My time machine is sending me a message; "The backup disk image "/Volume/Data/Dave's Macbook Pro "sparse bundle" is already in use". As a result, the time machine cannot complete a backup. Any suggestions?

Look at the more like this column on the right.. this is the most common problem reported here.
You need to restart the TC.. that is all..
Pull out the power cord.. count to 10.. plug in power cord.
There are a few occasions where this fails.. see C12 http://pondini.org/TM/Troubleshooting.html

I get a message from Time Machine ""/Volumes/Data/Don's MacBook Pro.sparsebundle" is aready in use. Please tell me what this means and what I should do because of it.

I get a message in a box on my desk top saying "/Volumes'/Data/Don's MacBook Pro.sparsebundle" is alreadyin use. What does this mean, and what should I do because of it if anything?

You should do a restart. That often fixes such problems.
AND You should tell:
System preferences > Spotlight > Privacy ...
not to index the backup drive (it does a special index already).
Does that message mean you are NOT keeping your backups on a separate drive? Backuops should be on a drive with nothing else.

HT3275 My error message is: The backup disk image "/Volumes/Data/Michael's MacBook Pro.sparsebundle" is already in use. Thoughts?

Hi folks - I didn't see my issue answered here, so I thought I would just toss it out there in case anyone had advice.
My error message is: The backup disk image “/Volumes/Data/Michael's MacBook Pro.sparsebundle” is already in use.
Thoughts?

Look on the right hand side .. more like this.. I am surprised you can have missed it.. we get about 10 requests a day now to fix it.. especially since Mountain Lion has made it 10x worse.

Getting this message:he backup disk image "/Volumes/Data/alicia's MacBook Pro.sparsebundle" is already in use.

So my time capsule is 1 year old exactly and now I am getting this message:he backup disk image “/Volumes/Data/alicia’s MacBook Pro.sparsebundle” is already in use. what does this mean and how do I fix it? i have 1.84T left of space. I have been using this time machine successfully for exactly one year and just now am having an issue.
Thanks,

This error involves a complex procedure to remedy the problem:
Pull the power cord from the back of the Time Capsule
Count to ten
Plug the power cord back into the back of the Time Capsule
Wait a few minutes and try a backup

HT3275 he backup disk image"/Volumes/Data/Sue's MacBook Pro.sparsebundle" is already in use mean?

Can anyone tell me what "The backup disk image"/Volumes/Data/Sue's MacBook Pro.sparsebundle is in use mean when it comes to using my Time Machine. How do I solve this blip in the back-up process?

The TM backup has not properly dismounted the drive on the last backup or has lost connection in some way.
It is a common problem.. the most common in this discussion area.. look at the right hand "More Like This" column for multiple similar threads.
Solution is simple.. some sort of restart is needed of the TC.. you can do this via the airport utility or just pull the power, count to 10 and power it on again.
See C12 for more details.

10.5.8 update corrupted the Volume Structure of my MacBook Pro and iMac

After installing the 10.5.8 update on my Macbook Pro AND my iMac, BOTH computers refuse to boot up. If I boot from a TechTool Deluxe DVD and run the system scan, It fails both the Directory Scan and the Volume Structure test. The only common application on these computers is the Fusion PC emulator. I was reading that the newest update fixed problems with this application. PLEASE HELP!!!

Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious!
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a weeks or two while you regularly check their websites for updates. This applies particularly to plug-ins for Safari 4.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
If you are updating Safari (or just have):
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very first thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
• /Library/InputManagers
• ~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).
