Sound icon is greyed out at start up (though sound can be heard); only workaround found so far: plugging in/out earphone, then sound icon is reactivated

Hi,
On my new MacBook Pro / Lion, Sound icon is greyed out at start up, as well as the output volume in System Preferences (though sound can be heard, you just can't change the volume); only workaround found so far: plugging in/out earphone, then sound icon is reactivated.
Do you have any idea? Concurrent access to sound output from another software? (Skype, Growl...?)
PS: in Windows 7 / bootcamp, volume settings work perfectly from start up
Many thanks,
Fred

Hi macwzrd, I followed your procedure and... IT WORKS!! I rebooted several times now, and I still have a true black sound icon in the menu bar. So the issue seems to be fixed, thanks!
BUT now, _coreaudiod process is taking *much* of my cpu resources (136 coreaudiod _coreaudiod 114,7 5 3,4 MB Intel (64 bit)) and the fan keeps turning on and on like mad...
Any ideas on how to stop this strange behaviour?

TS2634 When ever I plug in my earphones the sound comes out really low

When ever I plug in my earphones the sound comes out really low and you barely can hear it.

The volume is set very quite I guess. Try adjusting the volume with the bottoms on the side. Your earphones could maybe cause some trouble too, are they damaged, are they as quite on another device?
Also note that your iPad remembers the earphones and will always adjust it back to the last setting these earphones had.

My iphone 4S doesn't show the volume controls when playing videos and the speakers don't sound. But if I plug in the earphones then I can hear fine and the volume controls appear on screen. Please someone help.

After a week or so of installing IOS 7 now I having this problem, the speakers don't work for videos, music or apps sounds, but they work fine for using the speaker phone. It's definitely some software issue as the volume control appears when i plug in the earphones, but disappears when unplugging them, same happens with the volume buttons on the side, they don't work when trying to use the speakers, but the work when using the earphones. Please help if you have a workaround for this. I don't want to carry my earphones all the time to listen to videos and music.

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack or other hardware problem.
Apple Retail Store - Genius Bar
If not under warranty Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.

My daughter locked herself out of her ipod. She can't remember the password and now we are locked out. How can I get back in or restore it after she forgot her password?

My daughter forgot her password on her iphone and we cant get it unlocked. Is there a way to bypass her password or restore the phone so she can use it again?

Did this back along to mine. Plug it into itunes on your pc (or Mac) and click on the ipod icon on the left hand side. When the device options come up on the main screen, click on restore. Follow the steps and it should restore to factory settings. If you had icloud activated on the ipod all previous purchases should be in the cloud and ready to download onto the ipod afte rit has been restored to factory settings, otherwise you'll have to download them all again. Hope it helped.

No one has your password.
There is no way to recover it.

BIS = BlackBerry Data Plan. You should be ok then.
Do a simple reboot on the BlackBerry in this manner: With the BlackBerry device POWERED ON, remove the battery for a minute, and then reinsert the battery to reboot. A reboot in this manner is prescribed for most glitches and operating system errors, and you will lose no data on the device doing this.
Now, try your WiFi connection again.

I can hear people on call but sometimes they can't hear me, it maybe fine for afew mins but then sound drops again? Anyone have this problem and find a solution? Thanks.

I have an Iphone 4 13.5 GB, iOS 7.1.2. Currently when I make a call or someone calls me, I can hear people on call perfectly but sometimes they can't hear me. It maybe fine for afew mins but then sound drops again? Anyone have this problem and find a solution? Thanks.

I have taken it back to the Apple store genius bar, but they say they don't see anything wrong. Well unless you use it all day and experience the problems when they happen, you wont see anything wrong. But there are lots wrong with it. But this would be the same store as I purchased the phone. And they backed up my old Iphone 4, but were not able to get anything to load back onto my new phone. So, I lost pretty much everything. But over time, some of my contacts have started showing up, although i am still missing over 800 of them.

My iPod 4th gen sound won't work when I plug in my earphones and ALL EVERY sound is disoriented

When I plug in my earphones my sound of EVERY thing is disoriented and I already reset my iPod ( to factory settings) and inserted the headphones like 30 times and blew into it and still it doesn't work

Hi Jannine2131,
Based on your description, it sounds like you may need to have your iPod Touch serviced. You may find the following page helpful:

HT201401 Hi Iphone 4S not turning on!! took it into apple store today but they couldn't see anything wrong, ie all internals of phone looked ok just simply didn't work, out of warranty by 4weeks, what can i do?

hi, my iphone 4s has stopped working, was ok on tues night then black screen on wed morn?? took it into apple store today and they can't find anything wrong with it (other than it doesn't turn on) i'm 4 weeks outside warranty which means i have to pay £140 for a new iphone, surely this can't be right! the phone has just stopped working for no apparent reason, apple can't fix it because they can't actually find anything wrong with it to fix. i feel that i should get a replacement even though it is out of warranty as it is obviously a fault with this phone. has anyone else experienced this

You can pay them for an out of warranty replacement, or you can choose not to. It's far less expensive than purchasing a new iPhone.

Unstable harddisk won't go in dock - and icon is "greyed out" in Finder

Some time ago, I couldn't find my system disk in the dock in Finder (the thing to the left when you open a Finder window). I thought I'd accidently thrown it out, so I did a Sherlock search for it. I found the disc, but its icon was weirdly "greyed out", as if to tell me the disc was "deactivated" or so - and it wouldn't go into the disk dock.
I tried reformatting the disc completely, which worked for 1 day or so, and then the problem was there again. So I thought the harddisk was effed and bought a new one, formatted it and installed OS+programs yet again. After 2 days, the disk disappeared again and was, again, "greyed out" when I searched for it.
I've had the same setup with regards to software, RAM and HD's for almost a year prior to this happening, so it's most likely not a problem caused by new equipment going crazy.
Anyone see this before?

Dave,
Try doing a SMC reset and if that doesn't help try starting in Safe Mode.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Hi Holliecollie93,
It sounds very frustrating that you are unable to use wifi with your iPhone. I do have an article that I would like you to use in order to troubleshoot this, though it sounds as if you have already done some of the steps provided -
iOS: Wi-Fi settings grayed out or dim
http://support.apple.com/kb/TS1559
Specifically -
Resolution
Follow these steps to resolve the issue:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options.
Thanks for using Apple Support Communities.
Best,

The send icon is greyed out. This happened after a crash. Tried all the solutions suggested

I was writing an e-mail and had just spell checked. Thunderbird crashed. When it came back up, the send icon is greyed out (as well as the spell check. I ran through all the help suggestions (including the profile removal). The computer I am having trouble with is Lion 10.7.5. I have it also on 10.6.8 (snow leopard). I am about to give up and start using this computer (10.8.5) for mail - pain in the ..... to have to move everything!

Have a look and make sure your accounts still appear in the settings.
Tools menu > account settings.. It might be something is just rubbish following corruption caused by the crash, but I think it would be fairly obvious just scrolling through the account settings if they look like junk.

No Sound; All options greyed out

Output options for sound are greyed in Preferences and the desktop sound icon. In the Audio MIDI Setup window, the default output says Built-in Output and the System Output also says Built-in Output. No other options available for either.
Just below halfway down there is Audio Input, which has a bunch of info on the left, but on the right where it says Audio Output, there is just a greyed out message that says Output is Not Supported.
I also tried the option/apple/p/r, got the three chimes, but sound is still greyed out.
Any gurus out there who can tell me what simple thing I did to cause this, or is it a hardware/sofware bug?
Macbook Pro Core Duo 2 Mac OS X (10.4.8) 2 gig SDRAM 2.33 GHZ Core Duo 2

it doesn't matter if you've used the ports or not.. there is a sensor inside the audio ports that will automatically switch your audio in and/or out into digital mode if it trips and then 'thinks' there's a digital cable connected. basically, if you open your sound control panel and display the output pane and it says 'digital out', and the volume control (and everything else) is greyed out, and it says something about this device not having volume control... then this is exactly the situation where the port sensor has clicked on to digital and is staying there. unfortunately, the sensor seems to be quite fragile and there are plenty of users that are suddenly wondering why they have no sound, and why the sound ouput only says digital and the options are greyed out. it would be at least a comfort to be able to say that this only can happen if you've been plugging things into the port (such as headphones), but I've heard of this happening to people regardless.
anyway, look for the signs I mentioned: the digital output option being the only available choice in the sound control panel, with options greyed out. and also a red light coming out of the port. if this is happening to you, then you need to get the machine fixed cos that sensor is jammed.

IPhoto won't open, gives me an error message and the icon is greyed out on the dock

My iPhoto icon is greyed out on the dock and wont open. When I click on it it says it may be damaged or incomplete. Went to All Images and the photos are still in there. Went to aplications and the iphoto icon looks normal. Clicked on it and got the following error message. "You can't open your current photo library using this version of iPhoto. You have made changes to your photo library using a newer version of iPhoto. Do you want to quit and use the latest version of iPhoto, or do you want to create a new photo library?" There is a quit button with the message, but nothing to allow me to create a new photo library. So neither my wife nor myself have tried to upgrade iphoto. Not sure how it got a newer version. It was working fine a few weeks ago. Anybody have any ideas how to fix or restore the icon and iPhoto without losing pictures?

Hmm.
Rather than assume the account is "kinda" damaged, I would instead work on the basis that something in the account is damaged, and - as iPhoto is working correctly in the other account - that something is specific to this account.
So: Check on things that are specific to the account:
The Libraru
The plist files
The Cache files
are obvious approaches.
In the case you describe an awful lot of the time the issue is with the Library. This simple test will tell you if it is:
As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
If you can make a new Library and get it to work, then the issue has to be with the old library.
In that case:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .
