ITunes won't play audio with mp4 or mov video

I have wasted many frustrating hours now trying to get iTunes to play mp4 and mov videos but can't get any sound. A few months back it was working fine. Tried ALL the suggested fixes like uninstalling, updating and checking all the MIME/File boxes. When I went back to QT 7.5 and played the files independently of iTunes everything was fine. Quicktime 7.6, 7.67 & 7.7.1 do not play the audio independently or under iTunes and of course iTunes won't play video with QT less than 7.7.1. The same mp4 videos uploaded to my iPOD work fine. I currently have iTunes 10.5.3.3 installed on a Windows XP SP3 on an e-machines pc. Ideas please!!

I got this problem as well. Seems as soon as I moved to version 7.6 it stopped playing my video audio. My music plays fine, but my video audio is non-existant. It's not the file itself because I can play off my iPod (though not off my iPod through iTunes) just fine. I've done all the suggestions above and NOTHING has worked. Is there anything else we can find???

Itunes won't play file with .rm extension, what do I do?

We receive a weekly program via email and it has the .rm extension and won't play in Itunes, therefore won't go onto my ipod. i tried just changing the extension and that doesn't work. i tried importing it both ways into Itunes, and it won't import. It acts like it imported, but doesn't. What does one do?
thanks.

That I do not know. I don't use Real Player except when it opens for some Internet streaming.
Google might be your best bet if nobody else comes along to post here.
Also read the RP help menu or its manual.
Best of Luck

ITunes won't play audio

I recently installed iTunes on a brand new Sony Vaio running Windows Vista. I ran iTunes successfully for the last day or two, without problems -- I synced my iPod, added music, played music, etc.
However, today when tried to play iTunes, I found that songs wouldn't play, no matter how many times I clicked the play button, even if I tried to fastforward in the middle of the song. The same happened for song previews in the iTunes store. The visual on my movies seems to be okay, but there is no audio.
I tried restarting iTunes, restarting my computer, uninstalling iTunes and reinstalling it. I checked my driver software like the FAQ suggested.
Please help me! I want to use iTunes!

My Ipod won't play audio on my TV only video!

I've notice that everyone else seems to have a problem playing video on their TVs but not audio... If I play a video I hear audio, but if I want to hear music only I don't hear anything!
I own an Apple Composite AV Cable and it is plugged in correctly, but I can't still play any music. I own a 5th generation Ipod and a Samsung LCD HDTV.
Any suggestions? Should I buy a different cable?

Ive just spent days trying to solve this problem. Ive got an Ipod touch(2nd gen), Samsung TV and a component cable. When playing vids I got both images and sound but as soon as I wanted to just listen to my music and the TV failed to detect video signal - it closed off the component input displaying "no signal".
Its not ideal but if you have the official Component cable and a surround sound set up you should find enough cable to connect the audio cables to the Line in on your surround sound and the video feed back up to the tv.
Im pleased to report I can now enjoy my full library through my home theatre and watch the videos on my big screen tv.
Hope its of some help.

Yes there is.
Go to the iTunes Store on your computer. Click the "Purchased" link about halfway down on the far right side. Click the "All" tab on top. The song is there. Re-download it.

Itunes won't play, store won't play, no audio

itunes won't play, itunes store won't play, no audio.

Make sure the volume slider in iTunes isn't all the way to the left.
If that doesn't work, check out this Apple article -> iTunes and QuickTime for Windows: Audio does not play or plays incorrectly

Sound not working & iTunes won't play & Netflix error

Sometimes my sound stops working, and songs on iTunes won't play when this happens. Also if I try to watch Netflix an error message comes up: "Netflix Playback Error N8157 3140" and it says it could have something to do with my Silverlight plugin.
This is what it says:
The error you're seeing is related to the Silverlight plugin, which Netflix uses to play movies and TV shows on your computer.
This error is usually caused by one of two things:
A computer setting preventing Silverlight from storing files it needs to play your movie or TV show
An issue with the Silverlight plugin itself
To fix this error, follow the steps below for your Windows or Mac computer.
Reinstall your audio card drivers
Your audio card drivers may be out of date or corrupt.
Uninstall and reinstall your audio card driver. Your owner's manual or audio card manufacturer's website can help.
However, I have tried deleting and reinstalling silverlight, but it doesn't make a difference. Does anyone know what I can do to fix this? It only happens sometimes, other times I have no problems and it works fine.

Back up all data before proceeding.
Triple-click anywhere in the line below on this page to select it:
~/Library/Application Support/Microsoft/Silverlight
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Move the selected item to the Trash. Relaunch the application and test.
*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.

ITunes won't play quicktime videos on Mac anymore.

I'm using 10.7.3
iTunes 10.6
MacBook Pro 2.6Ghz 4GB ram
iTunes won't play my video anymore and it's been a while I'm not sure when it occured if it's after an update to snow leopard or iTunes updates...
When I double click a video I get "This movie requires QuickTime, which is not supported by this version of iTunes." ??
...and cannot convert the option doesn't work I get this other message when trying to convert a version for APPLE TV in advanced menu "None of the selected files were converted because they could not be found."??
But the movies are quicktime movies in my library and the MPEG-4 plays in iTunes but not on APPLE TV.
From all my videos I get one only going through APPLE TV and when I try opening it it says error occured why opening and never works??
It seems APPLE is regularly messing things up in updates to loose people so they have to pay for tech support, I didn't upgrade to iPhoto 11 and cannot import anything anymore into it so my entire library is a dead one ; not a cool way to do business than messing people software so they have to buy newer versions!!!
Any specialists that know how to fix this ??

The 32-bit solution has never, I repeat, never worked for me. I've even done a full reinstall on a clean drive of OSX Lion with a fresh install of iTunes downloading a video of "The Big Bang Theory" that just came out this last thursday and still get the error (just finished the full reinstall to a clean drive now and, no, I didn't do any backup restores.)
The only solution I've found is to remove the video from iTunes, without deleting the file, then import the file back into iTunes.
Switching to 32-bit iTunes to run the file causes iTunes to tell me it needs to open iTunes to play the file then it sits and waits for itself to open until I cancel the process. The video then plays without audio.
I have noticed that I can stream the files to my Apple TV to play even while getting the error trying to play them on the computer I downloaded the files onto.
As a result of this error, I've had to reduce the amount of content I purchase from iTunes. no more buying whole seasons at a time unless I do it at the start of the season. Even then, I'm reconsidering it. The amount of work required to get the files into a playable status on the computer is simply too great on an on-going basis.

iTunes won't play music videos.

Hey guys, here's my problem.
I had some major issues with OSX last week that a trip to the Apple Store couldn't fix. Their only advice was to save all my pictures, music, documents, etc. and reformat. I did that yesterday. I reinstalled everything and then downloaded all the most recent updates.
Today, I can play all the music I own in iTunes (music imported from CDs, bought from other sites, and music bought from iTunes itself). However, it won't play any of the music videos I have (all bought off iTunes).
I have authorized the computer again and again. When I try to open the videos in Quicktime it tells me that I don't have permission to play them and that I need to authorize the computer.
I'm lost. Any help?

Yup, this Audio but no Video WAS exactly the same trouble I was having, on my MacBook and iMac but not the other 2 MacBooks. This was due to the speaker settings at the bottom right hand corner of the iTunes window. I do use multiple speakers via Airtunes, on the two that were having trouble but not the other two, and although the speakers were only set to the computer it still wouldn't play the video content.
Whilst the audio (of the music video) was playing I then went to reselect multiple speakers, which brought up the "*failure to connect to remote speakers network refused connection*" warning, then I unchecked the remote speakers to leave just the "Computer" and hey presto the video came to life.
Thank you Charles C n Miami and hope this extra info helps.
Happy Music Video Watching

ITunes won't play/QuickTime RunTime error -- Total Recorder related ...

Hello -- I am having some iTunes issues. It will not play any MP3s in my library ... it will play CDs, but I get an error message when I try to rip them. And, very odd, QuickTime gives me this error:
"The application has requested the RunTime to terminiate it in an unusual way. Please contact ehe applications support team for more information."
I know this is likely based on my installing the nefarious "Total Recorder" (boo!) and I'm well-versed in the issues it has with iTunes and have tried the fixed proposed on apple.com. I have removed it and even scanned my registry to make sure there are no references; and re-installed my audio drivers.
Any ideas?
Dell Inspiron 700m Windows XP Pro

... it's hard in the poor places tonight ...
When I try to rip I get the cryptic "An unknown error occured (-223)."
okay. what antivirus and antispyware applications are you running at the moment?
i've seen one case of that one being caused by interference by an antispyware package:
http://discussions.apple.com/thread.jspa?messageID=825155&#825155
(good lord ... and i now see Justin was getting the same "itunes won't play music" symptom too. i hadn't remembered that.)
perhaps first try switching your antispyware off (experimentally) prior to playing or ripping, to see if that helps. otherwise, let's try a reinstall with antispyware disabled (like Justin) to see if that helps matters.

ITunes won't play in Windows 8.1...help!

I just updated my computer from Window's 8 to 8.1 and now iTunes won't play anything at all. I can open up the iTunes store and everything else, but once I click on a song it will show that it is playing but nothing happens. I even tried moving "QTMovieWin.dll" from c:\program files (x86)\common files\apple\apple application support\ to c:\program files (x86)\iTunes but nothing happened after I did that. Is there anything else that can be done to fix this problem? Thanks!

I have searched high and low for the right solution for this issue. I'm on an HP Envy laptop, running iTunes 12, and just upgraded to Windows 8.1.
I tried the settings for bit rate as suggested above and it still didn't work, but I did solve the problem.
In iTunes I went to Preferences > Playback > Play Audio Using ... and changed the setting from "Direct Sound" to "Windows Audio Session"
Now my iTunes on my laptop works!

TS3159 Some songs that I've bought on iTunes won't play on my iPhone 3GS even though they used to and they will still play on iTunes. Anyone know what I can do to get these songs to play on my iPhone again?

Some songs that I've bought on iTunes won't play on my iPhone 3GS even though they used to and they will still play on iTunes. Anyone know what I can do to get these songs to play on my iPhone again? Please help!

No, I haven't figured it out. And no one from Apple has contacted me to help. Very frustrating. Sure makes me want to not buy music on iTunes and just buy CD's.
Do you have a 3GS too? Maybe it's something with that phone??

Why is Lion so slow? Everything takes 2-3X as long as before and iTunes won't play most of my movies.

Got Lion. Now, opening a movie with Quicktime takes 10 seconds, opening ANY application takes twice as long as before, and iTunes won't play most of my movies that used to play in previous versions of iTunes. I'm frustrated. Even the web is markedly slower with pages taking 5-6 seconds to load up (and they are simple pages sans videos).
What gives? Any solutions? Anyone having similar issues?
The ONLY thing that took less time was Disk Utility...it ran in 4 minutes when it used to take 7--8 minutes.

Lion is much more demanding on memory. It is almost unusable on my computers that have 2 gig of memory. On the macbook air I am typing this from, it is using 1.5 Gig of memory out of 2 gig. Anything like playing a movie is going to be quite compromised. SL used about 400 MB for normal low-demand operations. The memory is soldered on in this laptop, so I am screwed, but it is fairly cheap and easy to add memory to most others. OWC is a good place to look. Max it out. I think your iMac can take 6 GB.

IOS 6.0.1 Safari won't play audio files. Error: "Cannot play audio file."

I recently updated my iPad to iOS 6.0.1, now Safari won't play audio files in any format. Error: "Cannot play audio file." Previously, it worked fine. I tried downloading and using GoogleChrome and Opera Mini, and these also won't play audio. What's up??

Solved the problem. It seems that once iOS 6.0.1 installed, it caused all of my browsers to mishandle audio files. When I reset the iPad, that cleared up the problem.
Before upgrading to iOS 6, my browsers would "autoplay" the sound files. After iOS 6, "autoplay" is disabled so you have to manually click play to play them.
Nonetheless, everything is working fine again except for "autoplay," which I can live with.

So I've downloaded a tv series from iTunes onto my macbook pro, for some reason the episodes on my iTunes won't play at all. no sound and no images. any suggestions and help?

Hi,
As you have match, I suggest that you create a new library by holding ctrl whist launching iTunes. Select create new library. Sign into iTunes Store and activate match. You will now have access to your music and will be able to stream your music.
Options : get a new external drive formatted for mac and either download music from match or copy music from old drive to new one. Alternatively you could reformat old drive and download music from match - I would not be comfortable using this option as it means erasing drive before being able to use with mac.
