HT1750 My computer has no audio. It had been working and last week the audio stopped working.
I have an Intel-based iMac and there is no audio. software: OS x 10.9.2
I have no audio.
There are many possible causes for this issue. Take each of the following steps that you haven't already tried.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. If you've installed a software equalizer called "Boom" or anything similar, update or delete it and restart.
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select the Output tab. If the Mute boxes are checked, uncheck them. Move the Volume sliders all the way to the right.
7. If a red light is coming from the audio-out port, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Reinstall OS X after backing up all data.
14. Make a "Genius" appointment at an Apple Store.

I was trying to update itunes on my computer that has windows vista. during the update I received an error message; so I uninstalled itunes and reinstalled it. the instatlation process stopped with this message: "Service 'Apple Mobile Device' failed to start. Verify thta you have sufficient priviledges to start system services." I have used an ipad 2 since 2011 and have never had a problem with my itunes account or my ipad until now.
What steps do I need to complete to get my itunes account up and running again?Hi Kayleenfromwi,
Thanks for using Apple Support Communities. You may need to restart the Apple Mobile Device Service. This article has instructions for doing this:

Quicktime Restarts Computer, Has NO Audio
Quicktime Restarts Computer, Has NO Audio
Quicktime 7.7.2 Restarts Computer.
Summary:
1. Change the setting so the Computer does NOT Restart on Error.
2. Update the Video Driver.
See article on how to change the setting so the computer will NOT Restart on Error: https://discussions.apple.com/thread/743448?start=0&tstart=0
• Changed the Setting so the Computer will NOT Restart on Error.
• Updated ATI Video Driver from the Internet ( Computer > Properties > … > Device Manager, right Click on Video Driver and click Update Driver.
Now Quicktime did NOT Crash but still had NO Audio (See below).
Quicktime 7.7.2 has NO Audio.
Summary:
1. Install an older version of Quicktime (Ex. 7.6.5)
• I Updated the SoundBlaster Audigy Driver from the Internet (Still NO Audio when running Quicktime).
• Now that the Drivers were Updated, I Uninstalled and then re-installed Quicktime to see if it would make a difference (Still NO Audio when running Quicktime).
• Trying something else - I installed an older Version of Quicktime ( I used 7.6.5).
Now Audio worked when using Quicktime.
Computer Specs:
• AMD 3000+
• 3GB RAM.
• Windows XP Service Pack 3.
• ATI Video Card.
• SoundBlaster Audigy Sound Card.
Extra Notes: Even with my Windows 7 Computer - I only have 7.6.7 - it also works correctly - with audio.Qualcomm Pure Voice is still an export option in version 7.3 (as it has been in every version).
It fails to play in 7.3 as others have noticed. I didn't catch it in my beta tests of this version and expect it to be fixed with an updated version.
I just tested exports using that codec and they do play the audio. Only a few Pure Voice audio tracks I have on my machine fail. All use 22.050 Hz at mono settings.
A bug. -
my computer has crushed so i have to download I tunes again,and maybe all my information will be lost.but i had I cloud and last time when i used to i tunes they have asked me to do I cloud so i did,so now when i will again setup my computer and I tunes will i get all my Contacts and Inofrmations cause i had i have an account on I cloud
If you used icloud for your contacts and calendar then you should have no problem. They will all come back on the phone once you put the icloud user name and password in. Itunes does not store the contact information except in a backup file and if you were backing up using icloud you can use that backup to restore with.

I installed a new wireless router on Tues. (May4) up until that time I had no problems using Firefox. Now I cannot get it to open on one computer, and the other it will open but will not load. Wondering if it has anything to do with the router, my provider or our computers. Again, it had been working fine. I am also unable to open interent explorer now on either computer.
== User Agent ==
Mozilla/4.0 (compatible; MSIE 7.0; AOL 9.0; Windows NT 5.1; GTB6.4; AskTB5.6)Sounds like a problem with the router installation/configuration (likely) or a DOA router (very unlikely).
Visit the forums for the router manufacturer (i.e., linksys, d-link, etc.) and ask for assistance there. There is probably a link to help listed in the router manual. -
My iPhone 4S will not sync with the music I have selected in iTunes. Has anyone else had this issue and what is the best way to fix it.
Hi,
Setting up syncing
Before setting up syncing you should download and install the latest version of iTunes. Wi-Fi syncing requires iTunes 10.5 or later and iOS 5 or later. You can change your sync options at any time. Each time you sync, content is synced between your iOS device and computer to reflect new, updated, or deleted content.
USB syncing
Open iTunes.
Connect the iOS device to your computer using the included USB cable and select it in iTunes under Devices on the left-hand side. Some tabs may not appear if you do not have corresponding content in your library. For example if you do not have any podcasts in your library, the corresponding Podcast tab will not appear.
Click Apply, in the lower-right corner of the screen, to sync.
Wi-Fi syncing
Open iTunes
To set up Wi-Fi syncing, connect your iOS device to your computer with the included USB cable. Select your device under Devices on the left-hand side.
In the Summary tab, select "Sync with this [device] over Wi-Fi".
Whenever the computer and the iOS device are on the same network, the iOS device will appear in iTunes, and you can sync it. The iOS device will sync automatically when all of the following are true:
The iOS device is plugged in to power
iTunes is open on the computer
The iOS device and the computer are on the same Wi-Fi network
While the iOS device appears in the left-hand column of iTunes, you can select the content tabs and configure sync options.
Click Apply or Sync to sync the iOS device.
Hope this helps -
My computer has a white screen at start up and sits for hours. How can I fix my computer?
My computer has a white screen at start up and sits for hours. How can I fix my computer?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
QUESTION from an American in India:
How do I find the screen with my personal iPod (my name's iPod) so I can download from my purchased or free songs/pods from my computer? My iPod has opened to that for 3 years and this week I can't find it: not on purchased page or on Apple store page.See:
Recovering your iTunes library from your iPod or iOS device: Apple Support Communities -
When I start iTunes on my home computer (Not a MAC), it automatically shuts down, and gives me the message that the Data Execution Prevention security feature has shut it down...what to do?
For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

I have been updating my PSE since 10. Recently I purchased PSE13 as I didn't see an update for my 12. I was changing to a new laptop as my old laptop had been patched and worked and was showing signs of giving out. It was a Window's 7OS. My new one is a Windows 8 OS so I bought the 13 and downloaded it on the new laptop. Our desktop had died so I downloaded the 13 on the new desk computer also. Not thinking I downloaded 13 on my old laptop as I hope to get it patched up enough to be a backup for my photography. When I tried to activate it I realized that I had downloaded it too often. I didn't know you could only use it on two computers. Learn something new every day.. Any way I removed it and now my PSE 12 does not seem to be working. Now it could be something that I did or something that is an issue with the laptop. this laptop has all the previous editions on board as I always tried to update, except for the year I got a really good deal on Black Friday. I also notice that the new laptop has a copy of PSE 12 in the program list. To my knowledge I have never deactivated any of my PSE's except the extra 13 downloaded. Bottom line, do I need to go in and deactivate previous PSE versions and removed them from my computer? I could certainly use the space and secondly, can I deactivate the PSE 12 and then go back and reacitivate it and install it again on the old laptop or the desktop, whichever I deside would be the most appropriate place for the newer program. For the PSE 12 since it is an updater for 11, does the 11 still need to be on the laptop? thanks for anyone who can understand what I am trying to say and can advise me as to my next move. Thank you very much.

I had major issues with the iPhone 4s battery, however it’s resolved.
The tech who set the phone up at the Apple store did so with little training.
if you have a mobile me account. First go and move all your data to the cloud by going on your computer and logging in at me.com/move. The cloud has replaced mobile me, so there is no need for those two accounts
Also make sure that for any of your email accounts you set them up to fetch, not push. My tech person set them all to have the email servers push data to the phone. The new iphone4s antenna is extremely strong so it will continually try to access stuff that is pushed–***** a lot of battery life doing this. It makes it worse if you have exchange 2010 accounts. Something about changes made to exchange really suck battery life from devices that access such accounts.

I have forgotten my appleID password and the email it is linked to is deactivated, security questions aren't working. This is on my iPhone and iTunes acs so I can't sync with my new computer. How do I merge AppleID accounts and shut down the old one (when I have no password and the security questions aren't working?)
You cannot merge Apple ID accounts, that has never been supported.
You can contact the Apple ID Security folks per the listing in http://support.apple.com/kb/HT5699 and they can help reset security questions and get the account working.
