Volume controls stopped working properly for my LED Display

The volume controls stopped working properly for my LED Display (Mac Pro OS-X 10.6.8). The sliders go up and down, and the clicks are audible, but the sound levels remain the same. The internal speaker sound settings/controls are working properly. I tried restarting to no avail.

Resetting NVRAM?

Tecra P5 - Volume control doesnt work properly

Hi
Since upgrade to Windows 7 64 bit I can't turn the volume all the way down by using the volume control at the front of the notebook. Worked fine under Vista 32 bit.
The volume control still works but no matter how far I wind it to the left there is still sound coming from the speakers.
Any help appreciated.
Thanks
Warren

As far as I know volume control in the past was mechanical but now it works on different way and it is controlled by specific tool/utility.
To be honest Tecra P5 is not known to me but obviously it is Australian notebook model and according to Australian support page this notebook model is not supported for Windows 7.
That doesnt mean you cannot use it but this means there is not software package designed for Windows 7 that can be installed so I think there is no much you can do about it.
I know it is annoying but for volume control you can use Windows option placed in task bar.

MBP doesn't work properly with Apple LED Display

I wasn't sure if this should go in this discussion forum or the one created for the cinema display but this makes more sense.
Recently I've been using my MBP (silver with black keys) plugged into my LED cinema display docking station and it's really been acting crazy and not working correctly at all.
Yesterday the computer got stuck in a vicious cycle of putting itself to sleep every 10 seconds or so. I could wake it up with the mouse or keyboard but it would just immediately go back to sleep. I eventually had to hard shut down because it wouldn't give me enough time to do it the humane way.
Today I plugged my laptop into it and the mouse was messed up. The cursor was able to move but the buttons didn't seem to register with the computer. I would hover over the close/min/max buttons but they would't change and I couldn't click anything. The keyboard and everything else worked. Just not the mouse buttons. I had to restart to fix this problem.
Does anybody else have these incompatibility issues with a MBP and the LED Cinema Display??? I don't understand why it's doing this all of a sudden. I've had the display for a year, used it sporadically, and never had issues like this.

I think I may have discovered the problem with my computer getting stuck in the cycle of going to sleep after 10 seconds. It just did it again a minute ago when I plugged my MBP into the display.
I think it's related to the power plug not being all the way in. I have a case on my MBP which makes the power plug fit only one way instead of both (i.e. the direction the wire goes...towards the front or towards the back). When my computer wasn't working correctly previously I had noticed the plug was going back and forth between connected and not because it's magnetic and there's no secure connection into the plug's socket. So today I noticed the same thing. I adjusted the cords so it wouldn't be teetering and now it works.
Go figure....

The remote controls stopped working

I bought with an official Apple dealer the new i Pod Shuffle (generation 3) to use during my bike rides. After the first ride the remote controls stopped working and the voice over feature spontaneously started repeating the songs title. As well the volume control stopped working altogether. I didn't have time to return the Shuffle after only a week so I disable the voice over feature and keep on using my Shuffle with no volume adjustment, fast forward etc ….
After a visit to the Apple website I saw that several owners complained about this problem and assumed Apple would know about it and be ready to offer a fast solution. So picked an official Service Center as close as possible from my location.
First shock the Service Center was dirty, the paint obviously several decades old and faded, the light kept to the minimum.
Second shock not Tech on duty to check something as simple as a headsets. I realized there was no way to have a fast resolution to my problem. The Shuffle will be send to a regional repair center, I could have save the trip and just go to an Apple dealer. What the use to have Service Centers if they don't provide service?
Now when a product is returned, after 25 days of ownership (can't say use), a product designed by a company with the reputation of Apple you expect some kind of sign that the company is sorry, stands behind it's product and will do all possible to solve the problem. WRONG.
Third shock. The person who took my Shuffle obviously never saw a Shuffle generation 3 before or even knew it existed. She explained over and over that I may (but it sounded more like I will) be charge for the repair. Even asked me to pay upfront a basic fee to cover the time of a Tech checking on the product. And that the Tech will give me a quote if I am to be charged. Furthermore She found tons of reasons why eventually I would be charged to repair the product, however no technical person ever checked on the product. Well I guess only users read messages on Apple website not employees of Apple.
So what now? I am suppose to receive an E-mail in 24 hours to 5 working days, in which I'll be explained the result of the Tech investigation.
I guess most owners of Apple products have a better experience with the Customer Service or where the reputation of Apple being a “cool” company comes from? But based on my experience it looks like Apple's products and Apple's Customer Service may not meet Apple's reputation or customer's expectations. Or am I asking for too much?

I seriously doubt you were at an Apple Store and you were not dealing with Apple employees. You were dealing with a 3rd party shop that does work on Apple products.
Don't know where you are located but you could contact Customer Service at Apple and complain but they are somewhat limited it dealing with a 3rd party company. But they will at least have you complaint on file. Or you could attempt to find an actual Apple Store and take your Shuffle there. Or you could try one of the workarounds listed on the threads here.

Spotlight has stopped working properly. Even when a known file is entered (with full file name) in search, it fails to find it. Any ideas?

Spotlight has stopped working properly. Even when a known file is entered (with full file name) in search, it fails to find it. It finds some things, but is not to be depended upon. Any ideas?

Try reindexing spotlight: Spotlight: How to re-index folders or volumes - Apple Support
If you still have problems, open Console app, select All Messages, then search for mds in the search field. Then search for mdworker. See if there are any messages indicating it is having problems with certain files.
You can also delete the index altogether and cause it to reindex with a command in Terminal. I have always assumed the method above will do the same, but I'm not certain. You must run this command while logged into an admin account. Copy the whole line and paste it into Terminal.
sudo mdutil -E /
sudo temporarily elevates your privileges and will ask for your password. When you type it in, there won't be any response in the Terminal. Just type it and hit return.

Tab stops working properly if .swf is loaded by SWFLoader

Hello,
I have swf file built by Flash CS5. The file contains different user interface entities like dialogs and buttons.
All the objects are exported for ActionScript and controlled by the ActionScript code.
I made loader that loads above mentioned swf by SWFLoader and shows the content.
If I use this loader the Tab button stops working properly. It doesn't change the keyboard focus.
What is wrong? What have I missed?
Thank you,
Dmitry

I tried, but unfortunately, this doesn't help.
I also tried to implement IFocusManagerComponent interface by TextFields as told here http://forums.adobe.com/message/3127914
but It seems it's not enough.
I also found out that it's necessary to implement IFocusManager, but I can't find the example of the implementation.

17" unibody - volume keys stop working

after some time the f10/f11/f12 volume buttons stop working, (even the volume icon in the menu bar stops reacting) i have to go to sound in the system preferences pane to control the volume, or log out, after loging in they will work for a while - this can happen a few times a day
i didn't figure out what triggers them to stop working - does anybody know this problem or has a possible solution?

thank you for your reaction, it solved the problem temporarely,
but the problem returned,
it looks as if it is triggered by using a headphone, after plugging them out, the keys don't
work anymore
also with skype the sound acts strange, only the right speaker of the computer works - with
headphone both channels work - when i play itunes, both speakers work
i think i should do some testing with different programs and different headphones to isolate
the problem - suggestions are more than welcome

Play/Pause controls not working properly after IOS 8

I like streaming content off of a website I visit in safari. Before the update, I was able to play/pause the content from the lockscreen, I was also able to do it using my apple earpods. Now this feature doesn't want to work properly. It will work when I start listening, but if I let it play or stay paused for more than a minute, the controls stop working. If I press pause in the lock screen, nothing will happen. However, when I Slide-To-Open, the audio will start playing (or pausing) like I intended.

Follow-up to my earlier post that iPhone 6 Bluetooth not working correctly. I purchased a Jawbone MiniJambox to use as a speaker phone in my office. Everyone in our company thinks they are the best. However, it is experiencing the same issues as with all my other Bluetooth headsets. Everything works except cannot answer or hang up calls pushing the buttons on the Bluetooth devices. The Bluetooth patio speakers in our courtyard also have the same issue. However, my colleagues using iPhone 5 and 5s who did not update to iOS8 are using all Bluetooth devices without any issues. Apple says it is a problem with my Bluetooth device. Come on Apple.... This makes 7 different Bluetooth devices with different manufacturers. You cannot possibly believe the problem is with the Bluetooth devices when iOS7 works perfectly fine...
On another issue, my iPhone 5s worked perfectly fine in my vehicle entertainment center connected via USB. The vehicle entertainment center had complete control of my iPhone and iTunes. However, now I plug in my new iPhone 6 and it no longer communicates with my vehicle entertainment center. Again when I called Apple, they said my vehicle entertainment center needed a firmware update. Are you kidding me... That is a bunch of BS...!!!

ITunes has stopped working properly.

iTunes has stopped working properly.

Ok.
3 days ago, for no apparent reason my itunes stopped working.
This only happens after it has "synced" with the itunes store and prepares to upload remaining songs.
NOTHING has changed since then other than downloading latest itunes (11.1...whatever) which i was recommended to do after it stopped working.
I am using windows 7
Latest itunes version (for windows)
I have thousand of songs in icloud, which were uploading fine until 3 days ago.
Windows message reads something like: Itunes has stopped working properly, windows will now close the programme blah blah balh.
Bit annoyed. Tried copying the dll file from QT that somebody mentioned earlier. Also tried "repairing" programme and re-downloading update.
Not working still!!!! HELP PLEASE!!!

This will be likely caused by the Minimal Download Strategy not registering the Javascript on the page reload. You can turn off the MDS feature to test this.
You can either turn off MDS in your site, or register your Javascript functions with MDS to ensure they are called. To do this, you'll need all of your code to be wrapped in a javascript file (Embed this on the page using a <script> tag and
inside that file in a function, which you then register with MDS as follows (I usually do this in the first line of the javascript file):-
RegisterModuleInit("/SiteAssets/YourJavaScriptFile.js", NameOfYourFunction);

Mozilla Firefox plugin-container has stopped working properly

Mozilla Firefox plugin-container has stopped working properly. FOR THE UMPTEENTH DAMN TIME... HOW DO I FIX THIS on Firefox 3.6.13!?!?!?!?!?!?!?
''edited by a moderator - https://support.mozilla.com/en-US/kb/Forum+and+chat+rules+and+guidelines ''

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.

Stocks App Stopped Working Properly

The Stocks App on my 3G iPhone has recently stopped working properly.
When I open it, the current share prices all still come up as expected, but the numbers at the right hand side in the green and red boxes where it tells you the + or - shift for the day no longer show. Now they are all blank.
Has anyone else experienced this? If so, do you have any suggestions to fix it?

Have you tried a reset (hold the sleep/wake & home button until the Apple logo appears while ignoring the slide to turn off)?

I understand. I was very unhappy with Adobe when my PSE 11 stoped working properly. I had it for only about 6-7months before I updated my software on my imac and it all went downhill.... Then to add to that my Adobe account was hacked. Adobe never informed me of this situation. I heard through a friend that I should check to see if I was one of the very many who's online accounts were tampered with. I had to reset every single password and username for nearly 30 online accounts to avoid any further tampering with the hackers. And all Adobe suggested was for me to pay for an upgrade to PSE 12 which I did but wasnt very impressed to say the least ( i was on an online chat with them for over 2hours trying to get my PSE 11 issues solved to no avail). Then this sluggish performance starts happening again using the new version PSE 12?. I'm going to stay clear of adobe if I have the option to purchase similiar software from another supplier. I would and will encourage anyone else who has problems with there software to do the same. Older versions should work perfectly fine for ages. I wonder If Adobe is trying to get us all to pay for the monthly subscription option(s) to avoid having issues with older versions of their software. As the subscription option keeps you ontop of all the latest versions... I wouldn't put it past them.
All the best returned,

HT3669 After update the printer HP Deskjet F300 Series stopped working properly

I would like to notify you that i use drivers for HP Deskjet F300 Series Version 1.0.1 and after this update the version upgraded in version 2.0.0 and the printer stopped working properly. I removed from library all folder of HP drivers and then i re-install old version from .dmg file from this official link of HP and now it works properly again.

Hi ds5710,
I understand you have a Deskjet F300 series printer that is currently telling you it's offline and won't print. I will certainly do my best to assist you in resolving this issue.
If you're using Windows, I would suggest you start by downloading and running the HP Print and Scan Doctor as it should be able to rectify whatever is causing your printer to show as offline.
If that doesn't resolve your issue, or you're using a Mac, please get back to me with which version of Windows or Mac that you're using and I will certainly see what else we can do!
Please click “Accept as Solution ” if you feel my post resolved your issue, as it will help others find the solution faster
Click the “Kudos Thumbs Up" on the right to say “Thanks” for helping!

Firefox stops working properly after a period of time

btw, I can't type in this box. I'm typing this in another program and pasting it in.
Using Firefox 5. I just installed Lion yesterday for Mac, but this problem occurred even before I did so. After a period of time, FF stops working properly. I notice it when I try to open a new tab. It won't switch to the new tab and the screen turns blue. If I type in a web address, it looks like it tries to go there, but it doesn't. When I look at any other already open tab, it has the blue screen. I have to restart to get my proper web pages back.

Whenever I click on "More System Details" there are several things I hope I won't see. Your Conduit Engine is one of them. It is malware by any reasonable definition and a cause of major problems with Firefox.
Google for information and advice as to how to get rid of it. Someone may come along with more specific advice..
If things aren't perfect after that you could do some straightforward troubleshooting(Safe Mode, Problematic Extensions, Hardware Acceleration etc) - in default theme -
