Suddenly there's no sound while i use QT to play avi

i once could play most avi files in QT, but suddenly, i can't anymore, i haven't made any changes recently in Mac OS X, but have installed the Windows XP using BootCamp( some of the drivers which contained in the CD burned using BootCamp can't install in the XP, so there's no sound or internet connection in XP). So the sound problems are drving me crazy both in OS X and XP.
Who can make a list( it would be the best if u can give the link) of all the codecs i need to allow QT to play the AVI files. Thanks a million!

Hello Budgets,
I would be concerned too if there was no audio coming from the speakers on my iPad. I found an article with steps to troubleshoot audio issue. The title of the article says iPhone, but most of the steps are still relevant to the iPad. You can skip any steps that apply only to the iPhone:
iPhone: Can't hear through the receiver or speakers

Thank you for posting in the Apple Support Communities.

nno sound when I use in app streaming

Hello Saranginotes,
After reviewing your post, I have located an article that can help with iOS audio issues. It contains a number of troubleshooting steps and helpful advice for the issue you are experiencing:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker
Can't hear anything from the built-in speaker of your iPhone, iPad, or iPod touch? Maybe you can hear, but the sound is distorted, muffled, intermittent. Or maybe you hear static or crackling noises. If your iOS device has any of these issues, follow these steps.
Follow these steps and test the sound after each one.
Go to Settings > Sounds and drag the Ringer And Alerts slider to turn the volume up.
If you can hear sound from the speaker, then the speaker works. Continue with these steps to find the setting or switch that's affecting the sound. If you can't hear sound from the speaker, contact Apple Support.
Make sure the Ring/Silent switch is set to ring. If you can see orange, it's set to silent.
Restart your device.
Open an app that has music or sound effects. Adjust the volume with the volume buttons or the slider in Control Center.
Go to Settings > Bluetooth and turn off Bluetooth.
If there's still no sound, connect a headset. If you can hear sound through the headset, remove it and clear any dust or debris from the headset jack of your device.
If the device is in a case, make sure that the case doesn't block the speaker.
Use a brush to gently clear any debris from the speaker and Lightning connector (or 30-pin dock connector). The brush should be clean and dry and have soft bristles.
Update your device to the latest version of iOS.
If you followed these steps and still hear no sound or distorted sound, contact Apple Support.
Thank you for contributing to Apple Support Communities.
Cheers,

I have a new ipod nano 7th Generation. When I plug in the earphones, there is no sound, althought ipod shows song is playing. Any solutions?

I have a new Ipod Nano 7th Generation. When I plug the earphones in, there is no sound coming from the earphones, even thought the Ipod shows the song as playing. Any solutions?

And the Radio app probably doesn't work either.
The headphone jack on the nano is very tight when new. Push the jack all the way in, the plastic on the headset jack should be flush with the body of the nano.

There is not sound can't use f key to turn on of off by mute keyoff

I have no sound my my computer . I can't turn the on and off key and mute buy my key board , yes I am writting with it and offer keys work

An SMC reset usually fixes that.

HT1399 I have a windows pc. It has windows 8 installed and I've installed the newest version of itunes but when I try to play anything, it won't. There's no sound and it says it's playing but it does not. What can I do?

I have a windows 8 computer and I installed the newest version of itunes because I used to have an ipod and I have a few purchases that I wanted to listen to. When I try to play them it says it's playing but I can't hear anything. It does not even says it's played the whole way. It just stays at the beginning. It won't let me pause. I checked my computer sound and there is nothing wrong with it. So there must be some software problem but idk what it is. If anyone can help I would appreciated. Thank-you

Hi DJBentley2011,
Welcome to Apple Support Communities.
It sounds like there is an issue burning CD's in iTunes. Is the playback issue only occurring on a specific device and does the disc show up correctly in iTunes? The article linked below should help you resolve optical drive issues, it walks you through identifying potential issues and provides troubleshooting suggestions.

I hope this helps.

Using Quicktime to Play AVI files

My Canon PowerShot creates AVI movie files. These play fine on my mac through iPhoto. I then drag them to my desktop so that I can attach them to an email. When I email them to family who also have macs (who are on 10.4.2) with QuickTime, they are unable to to open them. When I email them to my Windows PC it says that the file is not a movie file and cannot be opened with QuickTime. I've tried importing it to imovie and saved it as a .mov but that did not help.
How is one supposed to play an AVI file outside of iphoto?
These are some of the errors I get:
QuickTime cannot open the file: "MVI_1670.MOV"
it is not a file that QuickTime understands (-2048)
Or Error -32

hi Nat,
I got the avi file in my email. this is what happened to me:
I waited for a couple of minutes for it to download then double clicked the icon file for the avi in the email and nothing happened.
I then hit the "save" button to save to the desktop. I did this twice and nothing was saved to the desktop.
I then tried to drag the file from the email body to my desktop and got the spinning ball. Mail turned unresponsive and I finally had to force quit it.
I went to .mac webmail and opened your mail there. I clicked to download the avi from the webmail. took a couple of seconds and then it opened in quicktime just fine. You have an adorable doggie!!
Next I went back and opened Mail.app again. This time I went to Window>Activity viewer to see what was happening.
In Activity Viewer I see that it is stuck on "downloading attachment" and "caching attachments"
It's been over 10 minutes and it still has those two things showing in the Activity Viewer.
Ok, 14 minutes went by and now the AVI file is finally showing up in my email message and I can play the file within the message.
I don't know but maybe they didn't give the file enough time to download to their computer. It certainly gave me problems until it was all downloaded.
I have the latest OS and the latest Quicktime and it plays fine on my computer.

When I convert my Videos to iPod there is no sound when I try to play them.

Help Please,
I have some music videos in iTunes and I have hit the advanced button and converted the selection to iPod. It converts them so that I can put them on my iPod but there is no sound at all when the video plays on my iPod. When I do this procedure to convert the video on iTunes it pops up another copy of the video on the iTunes movie section which I am assuming is the converted video. If I click on the original video on iTunes the video will play and I hear the music. If I click on the converted version that goes to my iPod I see the video but hear no sound. I hope you guys have some help for me.
Thanks in advance.

Quicktime or Quicktime Pro (which iTunes uses) don't convert "muxed" ( muxed means multiplexed where the audio and video are stored on the same track) video files properly. It only plays the video and not the audio.
See:iPod plays video but not audio.
You need a 3rd party converter to convert the file with both audio and video.
See this for help: Guide to converting video for iPod (Mac/Windows).

IPhone 5 making weird sound while using Viber

My iphone will start making strange low tone beep sound while using viber. Only when I close the app (holding it long at multi-task and clicking the X) will it stop. And then when I open it again it will start making weird beeps again. Please help.

Hey there kben,
I'm sorry to hear that your iPhone is having the same issues. This is not a known issue on the device so lets try and take a look to see what is causing it. Did you have this issue before the 7.0.2 updated? Please try a soft reset,http://vz.to/16Qv4Id and let us know if the issues persist.
If the soft reset does not work, I would recommend performing a hard reset on the device,http://vz.to/17aDIPT.
Let us know if you need any additional assistance.

There is no sound on my iPhone4. Everything is working fine, and suddenly sound goes off, any recomendation will be apreciated

There is no sound on my iPhone4. Everything is working fine, and suddenly sound goes off, any recomendation will be apreciated.
There is no sliding volume bar (in fact it comes and goes by itself).
Thanks in advance.

Thanks Ziad2000, I have already tried to restore to factory defaults, and the problem continues, let me make a broader explanation of the problem. I acquired my phone almost a year ago, and everything was working just fine, I bought an iPhone dock station and after a few uses of it, the problem started. I do not know if everything is related to this item.

I was downloading podcast video in my itouch using wifi, but suddenly my wifi got disconnected and now there is a link in my podcast list which on opening uses wifi to play that video. I want to delete that link. Right to left swapping is not working.

I bet this is too late but...
Are you trying to print through the airport express wirelessly or the built in wireless of the lexmark? If you want to use the airport express, there is no need to mess with the wireless printing on the lexmark at all. The airport express will be easy to set up, all the wireless setups through the printers are a pain.

Using FF to access my AOL emails I get "There was an error while loading the message. Please try again later." Access is OK via Chrome, IE & AOL's own desktop.

"There was an error while loading the message. Please try again later." is a recent (3/4 days) error message I get when accessing my AOL emails. I can access the page and move them between states but cannot open them to read. Chrome, IE and AOL's own desktop open emails OK & can access them from the wife's PC using my AOL details. Have cleaned the history tab of everything in FF, have also removed it with add/rem progs and reinstalled - still I get the above message.

Hello,
Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
Thank you.

<b>WARNING:</b> Do not run Firefox's uninstaller or use a third party remover as part of this process, because that could permanently delete your Firefox data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>

As there is no sound only picture when connecting my ipad, do I need to also use the audio cable from Apple TV to an older Philips TV?

I have just bought a black Apple TV and it works fine when connecting my iPad to a modern TV. However on an older Philips TV, there is no sound coming through. Do I need to use an audio cable from the optical digital audio port in addition to the HDMI cable? The TV's HDMI does not appear to support sound.

Thanks. However no luck with this TV so far. I've purchased a converter to give a digital audio signal from the optical digital audio output port. The TV has an input audio digital port, but I've had no success in getting sound so far.
Is there any setting in the Apple TV menu that may affect the signal. I've tried the setting for 16 bit signal, without any success.
Perhaps this Philips TV may just not be compatible with the new black Apple TV. I have talked at some length with Philips support desk, but they've offered nothing new.
