KB article - No sound from some applications, but system alert sounds play (Mac OS X 10.3, 10.4)
Another trick: If you have GarageBand installed, open it and then quit.

HELP Cant hear Audio !

I can hear out of the speaker when using speaker for phone calls. I can record a voice memo and play it back through the speaker. I cant hear music through my head phones when I plug them in. But I can hear a phone call through my speaker phone. I cant hear music through the speaker! When I hit the volume up and down on the side, either nothing is displayed or it shows a speaker but no dots underneith indicating that I'm pressing up or down. Again, when I'm on a speaker phone call, I can hit volume up and down on the side and the screen indicates that the volume is going up and down for the speaker. But as soon as I try to play music or a video nothing is displayed, as far as sound goes, and no sound comes out of the speaker.
Help! I just got my iPhone replaced, two monthes ago. ! AarrrggghhhH!

I forgot to include in my post that I had downloaded the new flash after the "no audio" began and it did not help. The problerm began some time after I installed OS 10.7.4.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Can't hear audio for movies on 1st generation ATV

Anybody know how to fix the audio while watching movies on first generation apple tv? On my apple tv, I can hear audio for music, music videos, youtube, internet radio and even movie previews! But..... when I pay for the rental download of a movie there is no audio - just visuals. I am connecting with hdmi. When I connect an apple tv 2nd generation to the same amp and tv, using same hdmi and even same power lead and same settings then there is no problem! Anybody know how I can get audio to work for movies for this?

I would suspect that it have to do with surround 5.1 settings
if you don't have such a speaker setup but have turned it on in appletv settings
the audio would likely be playing in the speakers you don't have
rather then the tv's speakers
your own material is likely not 5.1 surround but stereo
so there you dont get the problem

Hi Nik 123,
Welcome to the Apple Support Communities!
I understand that it can be frustrating when the sound on your iPhone is not behaving as expected. In this situation I would recommend using the troubleshooting steps provided in the attached article.

So my iPhone 4S started draining battery after recent update, battery got changed and it worked perfect for 3 days, all of a sudden the phone shut down and now won't stay on unless connected to mains... Claims its at 100% battery but thats impossible as it was at 30% before it shut down randomly.
Cannot receive any signal "searching" constantly.
Turns off as soon as removed from usb ... wont stay on connected to laptop!
HELP!

The iPhone includes a one year warranty. If an Apple store is not nearby, you can call AppleCare and handle an exchange under warranty over the phone. The exchange will be shipped to your door - someone must sign for the delivery so if no one will be at home, have it delivered where you work. You use the same box to return the existing iPhone back to Apple. Return shipping label and tape to reveal the box incuded - call the carrier with number incuded when the box is ready to be picked up. AppleCare will request a credit card in the event the existing iPhone is not returned within 10 days after the exchange under warranty is received.
Hardware can fail - it happens, which is why there is a one year warranty.

Have you tried to reboot your iPad? Hold down the sleep and home keys until you see the silver apple. Let it reboot and try agian.
Also, try power cycling your router. Meaning, unplug it, count to 10, then plug it back in. Let it reboot and see if that helps.

Ive had the BB curve for months now, all of a sudden I cant send pics, or LOG OUT of facebook, which leaves my phone wide open to anyone..

Hi and Welcome to the Forums!
Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.
Best!

I have been using the Adobe Digital for years. All of a sudden, I am unable to complete a download

I have been using Adobe Digital for years. All of a sudden , I am unable to complete a download from my library to the Adobe Digital. Can anyone help?

Has anything happened like an update to Digital Editions?
Two possibilities come to mind:
between them they are the answer to a large number of ADE problems, but I can't promise they will help in your case.
Also, a third possibility at the bottom.
1) ~~~~~
Sometimes ADE gets its registration/activation confused and in a semi-authorized state.
Uninstalling and reinstalling does not help.
Unfortunately, it often then gives misleading error messages about what is wrong.
A common incorrect message informs you that the ID is already in use on another computer and cannot be reused.
This can often be resolved by completely removing any authorization using ctrl-shift-D to the Library screen on ADE (cmd-shift-D if on Mac).
Restart ADE, and then reauthorize with your (old) Adobe ID.
In extreme cases on the mac, the following extra step has helped some people. Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash. If you are using 10.7, see Access hidden user library files | Mac OS 10.7 Lion. http://forums.adobe.com/thread/1265248?tstart=0
2) ~~~~~~~~~
There are lots of bugs in ADE2.0 (and 2.0.1). Try replacing ADE2.0 with the older but more reliable v1.7.2.
(You can have them both installed at once if you like.)
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
http://helpx.adobe.com/digital-editions/kb/cant-install-digital-editions.html
The forum software is sometimes corrupting the link above. There shouldn't be a blank in 'editio ns.html'. The following redirects to the same page: http://tinyurl.com/diged172
3) ~~~~~~~~~~
extension of (2). ADE2.0 will often not work with Overdrive library books if a Sony eReader is plugged in.
It isn't just that it won't interact with the Sony, it won't even operate properly on the book within ADE on the computer.

my apple tv (1st gen) has worked fine for a year/ All of a sudden it has stopped displaying any movies or tv. It only displays my movies or my tv that has been previously down loaded. however it appears connected wirelessly with good signal strength. Have tired swithing off both router and apple TV. Any ideas?

This is a known, ans ongoing issue. Rest assured you're not the only one affected. There are several threads here already discussing this, I suggest searhing them out if you want more details, and possible work-arounds for locally hosted content.

Cant hear audio

cant hear movies or video

Hi Edward,
If you cannot hear any audio there are multiple possibilities.
Either there is no sound at all from the Speakers, and you are getting sound from external speakers or headphones.
or you are getting no sound what so ever from any of the above devices.
first check to see if there is any mute button on the top of the keyboard. or if the speaker button at the bottom right of the screen (system tray has a red x to it)
If your computer has win7
Click on pearl button, or the start button, in the search field type in troubleshooter and click on find and fix problems.
a new window control panel will open try to click on Troubleshoot audio play back .
click next. this should automatically fix any minor problems with audio.
Else i would need the computer product number or the model to get the link for reinstalling the driver.
Thanks if you find that the above steps help you to find a solution. Please click on Kudos.

Cant hear audio on phone

i get a message thats says this accessory is not made for the iphone and it asks me if i whant to turn on the airplane mode on to reducce audio interferance and then i cant hear the audio on the phone

The message to turn on Airplane mode comes up when the iPhone detects something attached to the dock connector, and doesn't detect it as being an accessory that is made to the "Works with iPhone" standards. It can also come up when the iPhone detects certain kinds of interference.
In your case if there is nothing attached to the dock connector, it could be debris such as pocket lint, moisture, corrosion, or the dock connector port on your iPhone has a defect.
This article suggest being near a magnet may also cause the message to display, such as a case that uses a magnetic closure:
