Loss of audio in iTunes

I started having problems with my computer's ability to playback audio in iTunes or anything related to Quicktime as soon as I installed Quicktime 7.4 and iTunes 7.6.
Current symptoms:
Scratchy or glitchy audio
No sound at all in Quicktime player
Intermittant play in iTunes (songs sometimes stall at 0:00, file format does not seem to matter nor does particular song)
Sound will drop out entirely. Then, if I plug in some headphones, the sound will return. Upon unplugging the headphones, the sound will come from the speakers but eventually become scratchy and disappear once more.
Now that I've written all that out, I'm wondering if it's even a software issue. Soundcard maybe?

I had the same issues and someone posted this in my topic
"I would try rotating through different USB ports first. If that fails, try an Open Firmware reset - that'll clear all the info for the USB and FireWire ports.
To reset Open Firmware, reboot and press and hold the Command-Option-O-F keys until the Open Firmware screen appears. At the command line prompt, type in the following exactly, pressing Return after each line:
reset-nvram
reset-all
reboot"
I switched the usb port around and it seemed to work for me. well at least for the last 15 minutes. hopefully this works for you

Intermittent Loss of Audio

I rented Micheal Clayton on HD a couple of days ago (my second HD rental), noticed that the movie playback had intermittent loss of audio whether I set it to DD5.1 or not it made no difference.
The audio loss don't seem to happen at the same scene everytime I rewind and play it back all over again. It seems to happen at random scenes during the movie playback and several times there was no audio for nearly 5 to 10 seconds before it reappears and when I rewind and playback the same scene again, the audio seems to be alright for most parts?
I am wondering if any other users have had similar audio issues with rented movies from iTunes?
This is like my first rental movie which had issues with audio, the previous 3 or 4 rentals did not have any audio nor video issues. It's not my ATV unit either because movies and music videos which I already own, playback on it just fine in DD5.1 via Optical and HDMI. So the issue was just with that one movie which I rented then.
I am wondering how could one demand for a refund from Apple when faced with such problems or issues after the rented movie dissappears from your ATV 24 hours later??
Now I am feeling cautious to rent another movie, what if I have another issue with which ruins the movie experience?
I think I will stick with my PS3 and Blu-Ray for now.

Not sure but I thought I read in another issue that if you connect a TB cable from your Mini into the TB port on the display and the audio/video is OK then that would mean the built-in cable is bad. I have never tried this so not sure it would work. Hate to buy a TB cable just to test because of cost. The other way would be to take to Apple store and have them check the cable. It contains miniture IC boards and one could be bad.

When I upload audio from itunes into my imovie project, it does not show all of the track?

Hi, I have opened a new project in imovie - I have uploaded 200 photos into the project to make a Comic Book movie!
this project is 7 mins and 8 seconds long - the exact length of the audio track that I want to play during the movie!
I have selected the music by clicking the musical note button in imovie, which open up my itunes library and displays the track I want to use that is 7 mins and 8 seconds long.
When I click and drag my MP3 audio from itunes into my imovie project, i only plays the first 5 mins & 33 seconds; leaving my project in silence for the final 1 min & 3 seconds????
I have not added markers, there are no fade ins or fade outs - only the first 5 min & 33 seconds or a 7 min & 8 seconds MP3 Audio track???
I have spent 10 hours trying to rectify this problem.......
can anyone help me with this problem
Peace, Love & Happiness

What can I do simply to keep all my previous contents, (own pics, videos, etc.) on my previously authorized iPad on PC, but get a new authorisation and a right syncronization, without data loss with a new iTunes on my new Mac?

Friends,
I already had an iPad(1) and its full contents (not only the purchased items, applications from Apple, but my all own pics, videos, songs etc.) is normally syncronized with an authorized PC (Windows) computer.
Now, I've bought a new MacBook Air computer, and want to sell my PC. But I don't know how to transfer (or syncronize) all of the contents from my previous iTunes on PC to the new one on the Mac.
When I connected my iPad to my new MacBook Air, I promted, if I want to change authorization of my iPad to the MacBook.
But also got a warning, that the new iTunes will delete from my iPad all my previously syncronized items, pics, videos and music, with the previously authorized iTunes on the previous computer, expect the saved pics from the net.
What can I do just like that, simply to keep all my previous contents on my iPad, but have a new authorisation and a right syncronization, without data loss with the new iTunes on my new Mac?
Thanks a lot for your answer.

Here are some instructions that I have posted several times that may be helpful to you as they have been to others. You can simply ignore anything that does not apply or that you have already done.
As Alan stated above - transferring the iTunes library is the best first step. If you can transfer the iTunes library to the Mac, most of this will be unecessary for you to do.
Very Important ....
1. Authorize the computer.
2. Turn off auto sync in iTunes
3. Transfer purchases
The text in italics is from the other thread - non italics are my words.
The following was copied from this thread. This is essentially what you want to accomplish.
https://discussions.apple.com/message/11527071#11527071
1) Without connecting your iPad to your new computer, start iTunes. Click on iTunes. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
2) Now connect your iPad to your computer and start iTunes.
3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
4) After it finishes transferring all your apps to your computer, right click on your iPad and select Backup your iPad.
5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
If everything on your iPad looks good after the sync, go back and click on iTunes / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.
Read this thread and the support links as well. There are apps that you can purchase that will allow you to transfer photos from the iPad to your computer. Look at Photo Transfer App in the App store and you can search for others as well.

One final note - you may want to leave auto sync turned off - but that is totally up to you. I never did use auto sync.

No audio from iTunes 11 on windows 7

I get no audio on playback from newest releases of iTunes 11.1.5.5 on my Windows-7 laptop. This is whether I am trying to listen to groovera.com channels on the internet option, or direct playback of a CD inserted. In all cases iTunes appears to be playing, yet no sound comes out of the speakers or headphones. All other programs (Spotify, Pandora, etc) use the speakers ok. I have uninstalled iTunes and freshly downloaded it several times. This situation has persisted through several releases over the last few months; I do not remember with which release the problem first started. I have no idea why. I have looked at Windows Firewall settings, etc. I have a feeling the answer lies in either iTunes settings or possibly permissions within Windows, but have no clue what to look at. Help?

Hello Ozboz1,
It sounds lke you are not hearing audio in iTunes when playing a CD or listening to internet radio. I recommend first checking out this info from the article named:
iTunes 11 for Windows: If you have trouble playing music or other audio
http://support.apple.com/kb/PH12335
If the progress bar at the top of the iTunes window is moving, but you don’t hear anything
If you’re using your computer’s built-in speakers: Make sure the volume control at the top of the iTunes window isn’t turned down, and that your computer’s output volume isn’t turned down (in the “Sound and Audio Devices Properties” control panel).
If you’re using powered speakers connected to your computer: Make sure the powered speakers are properly plugged in to your computer’s audio port, plugged into a power source, and turned on. Also make sure their volume isn’t turned down.
If you’re using remote speakers and the iTunes volume control is dimmed: Make sure Computer is selected in the AirPlay pop-up menu at the top of the iTunes window. Then choose iTunes > Preferences, click Devices, and make sure “Allow iTunes audio control from remote speakers” is not selected.
If you’re trying to listen to music through remote speakers using AirPort Express: Make sure the remote speakers are selected in the AirPlay pop-up menu at the top of the iTunes window. If you only want to use the volume control on the speakers, choose iTunes > Preferences, click Devices, and select “Allow iTunes audio control from remote speakers.” Make sure the volume control on the speakers isn’t turned down.
If the issue persists, try the troubleshooting in the following article to help isolate it further:
iTunes: Troubleshooting issues with third-party iTunes plug-ins
http://support.apple.com/kb/ts3430
If the issue still is not resolved I would next use the following article to help investigate conflicts with Windows:

Thank you for using Apple Support Communities.

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?

When converting from a .wav to a .mov is there a loss of audio quality when using QuickTime?
That would depend on your work flow. MOV is the generic QuickTime file container and is not related to any particular data compression format. If you perform a simple "Save" or "Save As..." action that merely copies the data in the WAV file to an MOV file, then the data remains unchanged and maintains its original quality. If, on the other hand, your transcode/re-compress the original data to a different compression format, then there is always the potential for some loss in quality. Depending on the codec and/or settings, the potential loss could be inaudible to severe.

No audio in iTunes

"Suddenly" (isn't it always?) I have no audio in iTunes (10.6.1).
Audio in other apps is fine. May be something obvious, but I'm stumped. Any ideas?

I had the same problem. I was able to get sound again by going to "sounds and audio devices" in control panel. I found a "mute" box that was checked. How it got checked is a mystery, but others have reported losing audio when updating to most recent iTunes, so I can only assume it did something wacky during the install.

No Audio in iTunes after 10.1.1 Upgrade

After upgrading to iTunes 10.1.1, I have no Audio in iTunes for Music/Podcasts.
Audio works fine in iTunes for movies/tv shows but not music/podcasts. I validated the audio works in all other programs, Quicktime, etc.
Tried reinstalling several times, same behavior - Any thoughts?
Running Mac OS X 10.6.5

If it play video but not audio, normally is an audio codec trouble. Movies may using other codecs than your musics. Strang this happening when upgrading... You may try play the music with QuickTime, if still got no audio, than is the codec.

I am not able to download mp4 files (video and audio) to iTunes since I updated to iTunes 11. Thanks for your help.

I am not able to download mp4 files (video and audio) to iTunes since I updated to iTunes 11. Thanks for your help.

Thank you for clarifying. Your question is in your browser, not in iTunes. Each download link is different, and it has nothing to do with the File menu. You can save media files by secondary-clicking on the link to the media file and selecting Save File to "[your downloads folder".

I've imported a giant cd collection for my boss in wav format for the best quality audio using iTunes version 11.1.1. I need to transfer this library to our Music workstation using iTunes 11.0.1. That workstation version of iTunes can't be upgraded for compatability reasons with other software using iTunes. When I try to transfer the library I lose all of the CD metadata and end up with only track names. Is there a way to transfer everything along with the metadata?

Not easily. WAV format does not store tag information in the file. Realize both AIFF (equivalent to WAV) and Apple Lossless (full quality but smaller files) do, so WAV was unfortunately the worst format to chose.
If you have to go with what you have you will have to explore exporting the library as .xml, moving it and the files to the other computer, then rebuilding a lower version library with the two sets. I am not sure if you can do it with the library.xml file that already exists or if it too differs according to version. You may end up having to export the files as a playlist. You will, of course, lose artwork too, though you can try fetching it from the iTunes Store later.
Some of what you need to do is outlined in these articles though you have the added limitation that you are not building a library of the same version. (It really is a piity you choose WAV, otherwise you could have simply added the ripped files and most of the data would have traveled with them.)

Audio from itunes doesn't play well in imovie HD 6

I have quicktime 7.1 and imovie HD 6 and my audio from itunes plays only for a few seconds and goes out and doesn't play anymore throughout the movie. I'm only using photos and no transitions at the moment. It worked completely fine before upgrading to ilife 06. What am I doing wrong?
Thanks

Hello Tia,
iMovie has quite an issue with Music Store files. See Karl Petersens post: Stutter in iMovie 5 & 6 — causes and workarounds
http://discussions.apple.com/thread.jspa?threadID=534252&tstart=0
What you are looking for is workaround No. 5: Burn iTunes Songs to Audio CD
Generally it is recommended to work with AIFF files in iMovie/iDVD. To convert your iTunes music go to Preferences > Importing and choose AIFF Encoder from the drop-down menu. Now all music will be imported as AIFF. In addition to that you can ctrl-click existing files and choose "Convert to AIFF" from the pop-up menu.
Note that this will duplicate the files, so after conversion you'll have for example one m4p and one AIFF with the same name.
hope this helps

I have an older Sony digital camcorder, and I am having trouble importing the movie files. Sometimes I get the audio in iTunes without the picture. I have a Pinnacle Dazzle interface. What am I doing wrong. Is there a way to skip the dazzle device?

I have an older Sony digital camcorder, and I am having trouble importing the movie files. Sometimes I get the audio in iTunes without the picture. I have a Pinnacle Dazzle interface. What am I doing wrong. Is there a way to skip the dazzle device?

Chances are the pinnacle is producing .avi files or MPEFG1/2 streams - iTunes may know how to decode the audio but not the video. Download Handbrake and try running the Pinnacle files through it and adding to iTunes - use Universal format unless you have a specific device in mind.
Keep copies of the originals.
Another option might be to try to install Perian. Can't remember if the Apple MPEG2 plugin allows MPEG2 to be played in iTunes.
