    I found something intriguing. I have a 1GHz TiBook with the same problem. Seems to be systemic to all of Leopard -- Quicktime, VLC, mplayer all have problems. Even the system chime gets cut off sometimes. If I leave iTunes "playing" after it stutters and plug or unplug my external line out, the music resumes playing, at least temporarily (alas, only to break again shortly thereafter).

    I've tried everything at the following website except cleaning the caches (which is my next step)

    Kind of pathetic that the article you cite is dated Dec. 14 of last year. Three months of this problem and not a word from Apple or a posted fix.

    The iTunes feedback link is:

    My wife just told me the iTunes stuttering and stalling seems to occur only when she is using the remote speakers connected via AirTunes (AirPort Express). Hope Apple fixes this soon as it would be very difficult to coonect her remoste speckers sdirectly to her computer.

    Reported. Fingers crossed that there's a fix soon. I miss my music and it's unplayable as things currently stand.

    The plot thickens. I, too, just noticed today that Quicktime movie playback is jerky, just as the iTunes playback. Not so when viewing a movie within a web browser. Does iTunes use Quicktime to play music and I presume videos? That might narrow the problem to Quicktime if so. Perhaps we could revert Quicktime with Time Machine ...

    I think you're right- we've got a Quicktime problem here. I got the stuttering when previewing an MP3 in Quick Look yesterday. It seems to be tied to some sort of performance problem- network calls, especially from Safari, seem to trigger the problem.

    Alright, let's take this on! I bet between us we can work it out. Maybe?

    More observations: If I use my headphone jack "fix" I can get my audio working. Some files (some movies, MP3s) work fine, others seem to break it. Everything seems (both fortunately and unfortunately) to be playing fine now. The only significant change since last night is that Spotlight indexed my drive (I was getting stuttering even when I told it to bug off last night; I let it index overnight).

    When I go to bed tonight, I will start Leopard installing freshly on an external FireWire drive, and I'll use that install to try to play music. That way, I can hope to narrow down if its an incompatibility with my computer or a corrupted system file, although this intermittency is going to be obnoxious...

    Anyone else have any ideas? Can anyone give me more details on their setups?

    Well, I just installed the update for iTunes and Quicktime (which I believe is the problem), and MPEG1 files and iTunes stutter just as badly as before. Kudos to Apple for ignoring this problem totally. Really classy.

    Me too. Come on Apple, do something!

    Just upgraded from a PowerMac G5 (single proc) to a Mac Pro 2.8 GHz. Moved my music library using Migration Assistant (which was pretty cool, btw). Now, with OS/X 10.5.2 and iTunes 7.6.2(9), I have the same symptoms you've all described. My music stops abruptly and at random times during most songs. Each interruption lasts 2-4 seconds, and is accompanied by static. The "skips" don't occur at the same point in any song twice, so I know it's not data corruption. Quicktime has similar issues.

    I just bought one of the world's best multimedia workstations, and I can't even play music on it! My $50 iPod shuffle sounds better!

    I have tried deleting specific songs, and recopying them from original media to no avail. I still get skips. Apple needs to get on this.

    I spent about 3 hours yesterday working with a very helpful lady at Applecare support. We went through everything she and ultimately the software engineer could think of to isolate the stuttering problem. Bottom line: no change.

    So I reverted to my fallback solution that has worked to fix problems since OS X initially was released. That is to reinstall OS X from the original discs of whatever version (and reinstall all the updates as needed). I archive and reinstalled OS X 5.0, then upgraded to 10.5.2 with the 312 meg combo update at

    Both the iTunes and Quicktime movie stutter problems are gone. So I would recommend this procedure for everyone with the issue, and hope that those who try it report back to confirm or deny that it worked for them.

    Well, here we go again. iTunes worked for two days without stuttering - now it's back.

    I am using Itunes on a dual processor PC with 16 Gig Ram, 250 gig hard disk devoted exclusively to itunes Windows Vista Business. I moved the collection to a new computer believing the older slower computer to be the issue. Guess what I have exactly the same problem. I imported my entire song collection into Media player and can play the songs flawlessly. iTunes ***** and support is non-existent.

    I have the stuttering of Music playback if I browse through pieces most of the time starting with sec 08. Trying it a second or even third time shows the track is OK. Whenever i start a Movie Playback I have the same stuttering after som 8 to 10 secs but usually the rest of the playback goes well. Another miraculous thing: after importing a movie file w/o changing the location and starting playback for a test, returning to iTunes crashes the whole OS X 10.5.2 completely. I have to restart. If I quit iTunes first after importing and run the movie after relaunching iTunes, all works well. Seems iTunes got a load of bugs recently... So its a good thing I hea the music mostly from my iPhone and use iTunes more or less as base station and database.

    i also have this problem, only since updating to itunes 7.6.2

    i am running leopard on a powerbook g4 1 Ghz, which is stretching it i know, but i have never had a problem with itunes in the past. The problem is that the stutters are inconsistent. sometimes i will hear a whole song with no skip, but the next song will have a bunch of them.

    itunes 7.6.2

    I had the same annoying problem: iTunes would hesitate at the beginning of a song and then resume playing it. This affected ALL tracks in my 17,000+ library. No quarter.

    My fix was to uncheck crossfade playback in preferences. I have never used sound check nor sound enhancer so those boxes remained unchecked.

    Worked for me and ALL tracks play now with no stutter.

    Hope this helps some.
