iTunes Music Stuttering Issue

Very recently I encountered this problem with iTunes. I was running iTunes v I was syncing my iPod classic 80 Gig fine for almost 6 months, after which I connected my new iPod Shuffle – that is when I noticed the problem. All the songs in my iPod shuffle played like a bad CD with garbled noises and kept skipping all the songs after trying to play it for a couple of seconds.

I then realized that even while playing the songs right from iTunes had the same problem. ALL my songs, which were earlier working fine, now did not, EXCEPT one particular album, which I had ripped myself from the audio CD.

I tried to remember what could have possibly caused this to happen. Maybe it was connecting another iPod device? Maybe not, I have seen people do that before without a problem.

I then remembered that I had installed Winamp just a couple of days before, after which I opened iTunes only to connect my shuffle. Maybe that installation messed up things?

I was unsure. So here are the steps I took.

  1. Tried uninstalling Winamp, did not help.
  2. Pounded the internet for fixes, looked almost everywhere and every post spoke about changing the Quick Time Player properties – tried that but nothing worked. I desperately tried setting different combinations of output rate, sample rate etc. but nothing worked.
  3. People had suggested it could be because of insufficient RAM, since iTunes has a reputation for hogging CPU for its “CoverFlow” view – but that was impossible, Mine had 3 gigs of RAM, besides, the CPU usage when running iTunes was, on an average, only about 3-4%.
  4. I then resorted to System Restore as it was driving me crazy. I tried restoring my system to as early as 3 months back – still NO DIFFERENCE!
  5. Luckily it was a Friday and I had the weekend and I decided to devote as much time to it as it takes. I backed up my songs and fully formatted my disks and got my OS reinstalled.
  6. I then installed all my onboard device drivers and then iTunes and tried playing the songs – STILL DID NOT WORK. I was totally stumped!
  7. With absolutely no other ideas in hand, I aimlessly surfed the net for some clue and stumbled upon one link where the user mentioned that sound card drivers could be a possible issue.
  8. I then searched if any sound card upgrades were available for my Intel motherboard – there was one and I downloaded and upgraded to it.
  9. This time when I tested, I loaded music from a different collection as I childishly felt that the other songs were probably jinxed. But to my surprise it WORKED! All newly added songs played smooth! And when I tried to play the old files, they stuttered. So they were jinxed in some form indeed!
My conclusion was this – the music files that initially played bad in iTunes – is damaged forever. So if you are testing any of the fixes, remember to use new music files each time.

Also I noticed yet another thing – When I tried to play music in the default windows Media Player on my newly installed Windows XP system – almost all of them caused Media Player to raise this warning – The file you are attempting to play has an extension (.MP3) that does not match the file format. That explained a few things. Plenty of my files were badly encoded mp3 files, which regular players like Winamp plays without even a warning.

Some files played fine when I clicked Yes, but some played bad even in WMP! I then took aside the files that played fine in WMP and renamed the extension to .wma and tried playing it in WMP and this time the warning went off and it played fine. So a bunch of files I had were actually .wma files with just their extensions changed to .mp3. No wonder iTunes struggled.

I am glad it works for me now, but I am still inconclusive on what exactly could have caused this problem in the first place. Anyways, I am just posting this for people who might want some ideas to try out. Trust me, I know how frustrating the problem is!

Ive had this problem for a while and have finally figured out whats causing it!

Check your DVI monitor cables, if they are loose it seems to intefer with the sounds tons, ive just replaced my cables and tightened them up and the problem has gone. If i loosen my cables the problem comes back!

I had tried every suggestion I could find on google to fix the stuttering apart from re-installing Windows XP until I found a solution that works for me. Maybe it will work for you.

I've got Windows XP Service Pack 3, 2 gigs of ram and it was stuttering badly.

To fix this all I had to do was go to Task Manager by pressing ctrl-alt-del, right click on iTunes.exe under the Processes tab and set priority to Above Normal.

You will have to do this every time you use it unless you create a .bat file to make it happen automatically.

This is how I created the bat file (below). You will need to change the bit after "abovenormal" to wherever you have saved iTunes. Mine is saved on my P drive in the itunes folder, but yours will be saved somewhere else.

I opened Notepad and typed the following:

start /abovenormal p:/itunes/itunes.exe

Then Save As itunesloader.bat

Now all you have to do is double-click on that bat file to open iTunes in above normal priority mode every time.

Hope this helps some frustrated people out there.

I had the same problem with my PC.
It was working really fine until suddenly everything stutter, the sound and so as the mouse movement.
I almost tried everything that I read in the net, but the problems persist.

I also tried reading the thread about DMA and PIO thing, but that is beyond my problem.

I've spent hours resolving this issue and all I got is a headache and frustration.

I remember then that what might have caused the problem was the PCI IEEE 1394 that I installed, so I uninstalled it and put it out of the motherboard, but that did not resolved it.

I've read somewhere and here that System Restore will not really help, but that is the last thing in my mind that I have not tried doing yet(I did de-fragmentation and Disk Utility too-which took really longer than it usually does), so I gave it a shot...and TADDA!it resolved mine.

I feel like I'm in a cloudnine right now.

In case some of you have the same problem I had, you may want to try it.

And as for you Bro, I hope that you already have your problem solved by now.

Thanks for the post:D

(I tried creating a bat file too, but I didn't work for me)
