How do I restore missing sound output device in system preferencces?

How do I restore a missing sound output device in the System Preferences. My MacBook Pro only shows a Digital output in the Sound pane and a red light at the Digital Output Port.

If your model has an audio-out (headphone) port, and a red light is coming from it, 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.

Missing sound output devices

In Sound Output, only Internal speakers is listed. I used the headset jack (Apple supplied headset from iPhone) just a few days ago. Now the jack is not responding. Don't understand what happened to the rest of the list.

Go step by step and test.
1. Reset PRAM. http://support.apple.com/kb/PH4405
2. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
3. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Now plug-in the headphone, does it show up?
    Under Mute any of the boxes checked? If so, uncheck it.

How to use Airport Express as a sound output device

Guys,
Is there a way that I can use Airport Express as a sound output device? So, I can play all the sound on my HIFI.
thanks in advance

In order to listen to the non-iTunes audio streams through your Airport Express you will need to use the third party software Airfoil.

How do i restore missing files for i work 09 as it is asking me to reinstall but cant find the disk?

how do i restore missing files for i work 09 as it is asking me to reinstall but cant find the disk?

Hello Jessica472,
It sounds like you need to recover some missing files but do not have access to the iWork '09 disc you used to install it. If you have a Time Machine backup and know what files you need, you can use the "Restoring specific files or folders" section of the following article to restore them:
Mac Basics: Time Machine backs up your Mac
If you do not have Time Machine, you will need the disc to reinstall the software suite.
Thank you for using Apple Support Communities.

Sound output device

Hello,
Recently I have been experiencing problems with my sound in my iMac with OS X 10.6.2
In my sound output device list, I have the following:
- Headphones (Should be selected)
- Soundflower (2ch)
- Soundflower (12ch)
To hear sound from my iMac speaker or headphone, the Headphone option should be selected. However, everytime I reboot the OS, it go to the soundflower and I have to manually go to system preferences and select the Headphones. I don't even know what the Soundflower is and why it is there. How do I make the "Headphones" as the default selection?
This has been an issue for the past month or so.

Soundflower is an audio routing program that emulates an output. It comes in very handy for people like me who use studio monitors through an audio interface as Apple doesn't allow you to adjust the volume on such setups with a keyboard (no idea why, since it works PERFECTLY under Windows 7 on Bootcamp, but I digress). I'm not sure how you installed it by accident, but you can delete it if you don't need it.
To fix your issue you need to delete the audio preferences file (I forget where it is, hopefully someone can help me out), then select the headphone output again and it should remember your setting.

How can I restore the sound on my ipad

How can I restore the sound on my ipad please?
I have know idea what happened to it but I am disabled
and rely on it so much because it is so easy to carry around.
Please advise me how to restore it. I miss listening to my music
so much.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) http://support.apple.com/kb/ht1430
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.
iPhone: No sound or distorted sound from speaker

iPhone: Can’t hear through the receiver or speakers
http://support.apple.com/kb/ts1630
http://www.atreks.com/app-no-sound-on-ipad-4-%E2%80%93-what-to-do/
To solve some sound problems, just follow these simple steps
1. Go to Settings
2. Tap on General
3. Tap on Reset
4. Tap on Reset All Settings
What this effectively does is to reset some of your Settings to factory default. It’s not a complete removal of settings. It removes all of your preferences for Wi-Fi, Bluetooth, Do No Disturb, Notifications, General, Sounds, Brightness & Wallpaper and Privacy. It doesn’t affect your data. All of your email accounts will remain intact, as well as any SMS text or iMessages.
 Cheers, Tom

Sound output device problem since 10.6.2 upgrade...

wHey, I've had a look through some other forums and have found solutions and so on to this problem, which is basically this:
Since the 10.6.2 Upgrade my sound output device changed from 'Headphones' to 'Soundflower (2ch)'...The three options are as follows on Sound preferences through System Prefs...
Headphones
Sondflower (2ch)
Soundflower (16ch)
I use external speakers, so headphones is important to me, but everytime I change it back to headphones, the next time I restart the computer it switches back to Soundflower (2ch) ... It's only on my user account as all other accounts are fine, I've reinstalled OS X already, and have even since this problem started, bought a new iMac (no, not just cause of the problem lol)... Done a timemachine restore, yet the same is happening on the new iMac, and it's driving me nuts... I've called Apple Support they suggested reinstalling OS X, I've done just that, but it's still doing it... There must be something I have installed...Any help?
I'm hoping someone has some sort of Terminal code to switch it to set to 'Headphones' as DEFAULT Output, as there is no such way to do it on Sound preferences.
Any help greatly appreciated, thanks

Refer to Apple - Support - Discussions - System does not store my sound preferences or Apple - Support - Discussions - Sound preferences sometimes messed up after boot for removing Soundflower from your Mac.
However, AFAIK, there is no way to make 'Headphones' the default sound output device, since the switch among built-in audio, headphones, (& optical output on Macs with a dual purpose optical/analog output jack) is controlled by what you do or don't insert into that jack.

Upgraded to Lion and now my iMac doesn't recognise any sound output devices?

Any ideas on how to solve this? "No output devices found" is what the system preferences show under Output.

Hi Philip..
Preferences (.plist) may be corrupted after the upgrade ...
Go to ~/Library/Preferences
Move the com.apple.systempreferences.plist file from the Preferences folder to the Trash.
Restart your Mac.

Selecting the sound output device

Hi, is there any way to select which sound output device to use from an Adobe AIR application? If there is, I can't seem to find it (using either the manual, the forums or Google).
Any help will be greatly appreciated.
Thanks,
Michiel

there's no music in my device (ipod touch) after restoring content because of a software issue. music is available in my laptop's cloud though. how do i restore music in my device?

hi! an error message showed on my device last week and Apple support helped me restore the software on my device. Syncing went well and all my apps were available after. However, when I looked at my music in my device, it did not contain anything. The songs were in Itunes on my laptop and when I tried to play them they did not play. But, it says music is available for my account in the cloud. When I switched to the cloud, I was able to play my music already. But everytime I synced, the music from the cloud are not transferred to my device. Most of the music that I have are from other sources. How do I download those again to my device? I tried what I did before which was to copy the song from my laptop then edit paste it to iTunes but this did not work like before when automatically it becomes available on my device.
pls help. thanks!

Control sound output device

If I want to change where my sound is piped out, I have to open the Sound preferences>Output and choose Line Out, USB speakers, Digital Out, etc.
Are there any menu bar widgets that would let me control my sound output device?

There was such an animal, but I don't know if it's still around or works in SL. You'll need to search at VersionTracker or MacUpdate.
