HELP ME PLEASE- Internal speakers aren't recognized

So, here's what's wrong:
1- Under sound in system preferences- output volume is muted and I can't un-click it
2-Also under sound in system preferences no devices are found under output and input
3-The sound symbol doesn't show in the top toolbar.
Also I googled this same problem and a lot of other people say a red laser is coming out of the head jack on the computer, I however don't have this problem.

+The MacBook Pros always seem to have this problem - especially when they get used as 'portable' computers - correction - I mean used at all!... My 07 and 08 MacBook Pro 17s both developed this problem pretty much right away - and I rarely have anything other than one of these $100 'special' cables connected (and I always get an Atari graphics card too!). I have been working from home - so I doubt that it has been connected and disconnected 35 times - and no more than 3 or 4 flings with a dirty head-phone-jack.... so the problem is more than 'dirt' or wear. I live In Mexico, and it tends to be humid and dusty simultaneously.... so where other people might have a 'stuck' switch because of using it, disuse can cause it too. The point is - its not 'user-error', it is a by-product of having one 2mm hole interfacing with those iconic-white Apple 1$ ear-phones, $5000 home stereos, and $50 000 sound-boards... i suppose a mini-dv hdmi would be good.... I just remember my happy disbelief when I discovered the 'little-red-light' on my new and silent Mac - I thought that it jammed to spite my already disappointed frustration with the mediocre connection options I was tinkering with (I know - read the manual)... I guess it was just get me to leave the gold-plated Radio-Shack crap to Dell!+
+A sound card interface that is multi-channel headphone-jack AND optical is.... well, unheard of! It is fragile (optical tends to be... ) then again, when we get the best of both worlds - the real concern is that Apple will shelve it with the FireWire, and we will all be in the same spot as we are now - no sound, and trying to figure-out ways to convince each other that adapting our other equipment to pair with our wireless freedoms (airport express connected via - optical?) is w-a-y better that a sticky switched headphone jack that secretly held full spectrum optical Dolby deliverance!!!!+
+Oh yeah... the 'FIX' - which I read about here and there (and has worked on two consecutive machines for me) is to keep the little socket clean, and lubricate the mechanism into functioning - as opposed to 'toothpicking-it'! Clean it with electrical contact cleaning solution (with the battery removed!). LUBRICATE the 'switch' to get it working ad to keep it that way. I used WD-40 on the 2007 mac... but the right stuff is an ultra-light 'dry' lubricant specifically for delicate contact applications - I am not sure, but I believe that the operation is at least partly electrical, so a non-conductive would probably exacerbate the problem - and would only work until it made it worse. The other tip is to use the right cables instead of paperclips and toothpicks. I found that the 3.5mm to mini toslink - the cheapest - seems to 'fit' the best. Also, the longer of the Apple earphones (iPhone 1st Gen?) kind of 'clicks' in - I put one cable in, then the other - then with the battery in, and the computer on I again rotated the cables - for me it seemed to start working when I had the cables connected to the amp at one end and the MacBook at the other+

PLEASE HELP!- New internal hard drive not recognizing

I have a MacBook pro unibody, purchased October 2008, 250 GB, 2.4 GHz, 4 GB RAM. I bought a new hard drove from OWC, which is 750 GB. I followed all I strychnine from their website by installing osx again on the new drive, and transferrin data and updating the programs. when I checked the hard drive to see if the files were all there, they were. but once I installed in in the MacBook, and turned on, a blue screen with a flashing blue folder and a white question mark popped up. what did I do wrong???

Restart holding down the Option key, the system may not know the new drive is your start-up drive. Select the drive and once OS X is up go to System Preferences-Startup Disk and choose the internal drive.
If it still doesn't start then you made an error somewhere. The correct process would be to put the new drive in an enclosure and format it first to Mac OS Extended (Journaled), then using using SuperDuper or CCC clone your old drive to the new drive, once that has been done swap the drives and you should be done.

Help with my internal speakers

Yesterday my macbook was working fine... but ll of a sudden today I tried to play music and the speakers won't play. I try to turn up and town the volume as usual but there is a circle with an cross through it below the volume bar... Also, there is now a red light that comes out from where the headphone input is. Are my speakers broken or is there some special setting my computer is all of a sudden on?

Hi Charles: I haven't had this particular issue but, I have read about it quite a bit on here. The little switch inside the headphone jack becomes stuck in "Digital/Optical" mode. Most people have success by slightly poking the jack with a small toothpick or similar object. It would probablly be best to use something that was resistant to breaking inside the jack.
Good Luck

Internal speakers don't work

My husband uses the dual USB late 2001 iBook more than I do, mainly with Toast and a Griffin iMic to copy our old vinyl records to CDs, and to run VirtualPC for his PC model railroad design app. He does all this in OS 9.2.2.
I used the iBook yesterday, and discovered that the internal speakers aren't working at all. (He hadn't noticed!) No startup chime, no alert beeps, nothing. The sound settings are not set to "mute". I rebooted in OS X (version 10.1, the original, which we've never upgraded), and it didn't make any difference. Still no sound.
If we plug in a set of headphones or external speakers, they will work, playing the startup chime and all other sounds.
It's never been taken apart, so it's unlikely that the speaker cables have been accidentally disconnected.
So far, I've tried the following, none of which helped: trashing the Sound prefs in OS 9 and restarting; resetting the PRAM; starting in OS X and then restarting in Open Firmware, resetting the NVRAM and then resetting the PRAM again. I also tried the hint in This Post - restarting with the headphones connected and then disconnecting them. And I tried plugging the iMic into a USB port, and the headphones into the iMic, and restarting and then disconnecting. No use! The iBook Audio Update was already installed, so that's not it.
We've compared the iBook's OS 9.2.2 Sound control panel with the one on a 7300 also running 9.2.2, and notice one interesting thing. When the iBook is freshly rebooted, the Sound > Speakers tab has the headphone icon present and highlighted, even when the headphones aren't connected. One can plug in the external speakers, and select the speakers icon, and they'll work. But it always defaults back to a highlighted headphone icon upon restart - even when the speakers are plugged in. The 7300's Speakers tab does not show any headphone icon at all, unless the headphones are actually connected. But this is only in OS 9. I don't see a comparable setting in the OS X System Prefs, where I can check on the speaker settings.
It's as if the iBook's sound port thinks the headphones are connected, even when they're not. Could this be a hardware problem with the port, or some kind of logic board problem?
My next step will probably be a reinstall of both OS's.
Dorothy

Ronda and Dave2,
Thanks for responding.
I'm beginning to think it has to be a hardware problem. It happens in both OS's, and when booting from the OS 9 install CD that came with the iBook - no startup chime at all. But the chime is there when either headphones or external speakers are hooked up.
I did restart with Command-Option-O-F, got into Open Firmware, and followed the instructions for resetting the NVRAM.
The OS X Sound preference pane has only two tabs: Alert and Output. Output shows only "Built-in audio controller", no matter what's plugged into the output port. (In OS 9, the Sound control panel has 4 tabs: Alert, Input, Output and Speakers.) So, in X there's no way to know what speakers the iBook thinks it's using.
I haven't tried resetting the PMU; it didn't seem from the KB article on PMU reset that doing that would help this problem. (I'm cautious about fiddling with the PMU.) But, the battery is old, doesn't hold a charge very long, and we need to get a new one. We normally use the power adapter, anyway. So maybe a PMU reset would do something.
I did ask my husband - an experimental physicist - if the speakers could have been damaged by too loud a sound when he was working with Toast, and he said the the sound circuitry should prevent that, unless there were a design flaw.
On further thought, I probably won't bother reinstalling the systems - just wait until I get back to civilization next week and take it to an Apple Store. (The only authorized service center within 100 miles of this house is one CompUSA 50 miles away.)

Sound from internal speakers keeps coming and going.

My internal speakers aren't working consistently. One second I hear sound and then the next I hear nothing. I checked "System Preferences > Sound > Output" and can see that the selected device keeps randomly switching from Internal Speakers to Digital Out to Headphones. Why is this happening, and how do I fix it?
Thx

1. Reset PRAM. http://support.apple.com/kb/PH14222
    Do this twice
2. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the appropriate method.

IMac not detecting the internal speakers

I am new to Apple and just got an iMac. Sounds worked initially, but stopped after a software update. The internal speakers aren't being detected. Tried to reset the PRAM and unplug the system. Any suggestions??? Thanks.

Are you sure you did the smc and pram reset correctly?
Short of removing the audio plists in /Library/Audio I am not sure what the problem is at the moment.
By the way, look at the More Like This section on the right side of these pages for the similar problem.

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
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. 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. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
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 Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, 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. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the 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. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

IPod 2nd Generation Internal Speakers Not Working - HELP PLEASE!

A couple of days ago my ipod's internal speakers stopped working, the volume control dissapeared and no sound was coming out. Now, when i have my headphones in, music will be playing but every so often they will cut out and again, the volume control bar will dissapear. I then have to remove the headphones and put them back in. I've tried resetting the ipod and turning it on and off, no change.
Any help to solve it please? or is this the end of my trusty ipod?
Ashlee

Welcome to the discussions,
try to restore "as new ipod", don't use your backup to get your settings back to your ipod, it may contain the corrupt files causing this problem.
Make sure you transferred your purchases and synced your contacts/calendars before you start.

Please help! Audio problems...internal speakers

HI all...everytime I put headphones into my audio port, the system wont return to internal speakers once I unplug them. It stays on headphones and the built in speakers....wont work. I have to restart a number of times before it goes back.
Any help is highly appreciated
Kind regards
Phil

Interesting - after not being able to figure out ANY way to get the inputted sound to come through the speakers, I went to CD Spin Doctor 2.02 (Came with Toast), since the whole point was to input an LP and burn it. I thought I'd just do it soundlessly and hope I could edit the saved file afterward.
CD Spin Doctor has an option to allow playback through the speakers. I clicked it and it streamed through perfectly.
Now, it wasn't launched during all the fuss beforehand, so it being in active use isn't an issue. BUT, I suspect that it's installed something (?) that may have led to this issue.

Headphones Not Recognized When Plugged in, Internal Speakers Won't Mute

Hi all, I've scoured these message boards looking for a solution to this problem, but couldn't find a solution that worked. Hopefully someone can!
Toshiba Satellite C655-S5312
Edition: Windows 7 Home Premium, Service Pack 1
Processor: Intel(R) Pentium (R) CPU B950@ 2.10GHZ
Installed Memory: 4.00 GB
System Type: 64-bit Operating System
The problem I'm having is that my computer won't recognize my headphones or any other external audio device when I plug them in. The internal speakers continue to play no matter what. I used the jack fine one night and the next morning it wasn't working. I've checked these external devices with other computers and they work fine. My computer is just over a year old and no longer under warranty, but I can't imagine it being a hardware issue after such a short time of use. I had this problem before right after I got my computer back from a repair shop. Turns out the guy didn't reinstall my drivers. Now, when I tried to follow those same steps, I'm getting nowhere. I can say that I noticed that the available drivers on the Toshiba website have changed. Before it was RealTek and now, after updates, it' was SmartAudioHD and now High Definition Audio Device. I don't know if that bears any significance, but I thought I'd include that anyway. I've tried uninstalling the driver, but everytime I restart my computer it's there under Audio Device Manager. Tech Support said that my comp automatically adds the driver so I'll never really get rid of it. Does that make sense?
Troubleshooting steps so far:
1.) Uninstall and reinstall drivers (restarted my computer after)
2.) Control Panel---> Device Manager---> Sound, Video Games and Game Controllers---> High Definition Audio Device (was SmartAudio before updating driver during troubleshooting)---->right click and "Enable" is checked
3.) Control Panel---> Sound---> Playback Tab (in Sound Dialog Box)---> Speakers (HDAD) green check mark but Headphones (HDAD) red downward arrow and "Not Plugged In" (Can enable or test because it's not detected)
Am I missing a driver? Am I missing a vital step? Please someone help me!
Solved!
Go to Solution.

If you are using Windows 7, go into control panel click on sounds and make headphones default. When you are not using your headphones you will have to do this procedure again to restore speakers on the laptop or computer. I am using Microsoft Gaming Headphones and had to do this because my toshiba laptop did not recognize it was plugged into the USB port. I have no problems with the plain speaker headphones only the ones that plug into the usb port.

First, this is the Photoshop (full version) forum - you may be able to get more pertinent and specific help down at the Photoshop Elements forum:

Generally speaking, one edits image files then saves the results on one's hard drive, so the photos don't "go into" Photoshop, but rather they are just files on the disk.

Wow the customer service is even worse. Does Apple want me to go around jailbreaking my iPod now so I can use something that actually recognizes my product?
