Audio playback stuttering/skipping randomly itunes 10.1 mac 10.6.5

Having issues with playback on my mac since installing 10.1.
It seems to glitch a track randomly and skips a second of song or something.
7% of my CPU is in use and ive got nearly 4gig of ram free. itunes library is about 32 gig bit its never been an issue before.
Is this a known issue in 10.1 itunes?

the forums are full of discussions about this issue.today i suddenly had the same problem.stuttering music.i tried the following to solve the problem,and so far it seems to work for me:throw out all the music from your itunes player,but keep the files in the library.re-import the music you want to listen to from the library now,and see if it solves the problem for you,too.

  • New MAC PRO: itunes audio playback-stuttering, glitching, skipping

    I have a brand new mac pro 3.2ghz quad, with 8gb ram (bought a couple weeks ago). All seems fine with the exception of brief skips, glitches and stutters with audio playback in itunes. I tried updating to itunes 11 and this did not resolve the problem. My music files play fine on my girlfriends macbook pro (purchased over a year ago), and never had any problems on my old machine (imac 24inch aluminum). I went to apple with the problem and after multiple system recoveries they determined that the computer was faulty and sent me a replacement. I just received the replacement and tested out some downloaded music from the itunes store and the same problem happened. Am I just unlucky to get two computers with this issue? Is it the Mac Pros? Has anyone had this issue with mac based machines, specifically the mac pros? I saw another thread on the issue but seemed to be primarily windows users running itunes. The skipping happens as frequent as every 20-30 seconds to every few minutes, but it is definitely enough to notice
    Thanks.
    Baffled,
    Greg

    Hi Greg.
    I seem to have discovered this problem this weekend. I listen to a lot of music from my apple devices and have done for years. What I have noticed this weekend is that both my Macbook 2008 and iMac late 2010 both suffer with a brief stutter every minute or so making the enjoyment of listening to music a little annoying. Both are running Mountain Lion 10.8.2. My iMac is running the 2.93 GHz intel i7 processor with 8GB ram. Playing music should be a doddle!
    From my point of view both Macs are running independently to external speakers. The music I am running on those 2 devices has been ripped on both devices. e.g. Macbook has ripped and plays Apple Lossless format and my iMac has ripped and plays songs in 320kbps. My guess is its a bug with the new iTunes 11 or Mountain Lion although I have been using 11 since its release.
    While I'm not able to supply a fix I think its safe to say its not your new Mac Pro. One other thing to note is that I have been running up until this weekend a 7 or 8 year old Mac Mini as a media device in my kitchen playing Apple Lossless format with no issues at all. This device however is running Snow Leopard with all updates applied. The Macbook is now playing the Lossless music with stutters that was ripped on the Mac Mini that was playing OK.
    So is the problem Mountain Lion?
    Take care

  • ITunes playback stutters/skips

    I have the latest version of iTunes (7.6.1) and when I playback music from the hard drive or web radio it randomly stutters/skips every so often. The music on my iPod and iPhone plays just fine. Any thoughts on why this might be?

    This is a widespread issue, search the boards for "stutter" .... there must several hundred people posting on these forums with the same issue.
    I have my 300GB + iTunes library on an external WD My Book Pro (a 2TB version set up as a 1TB RAID mirror) connected via FW800. I solved my stuttering playback problem by transferring my library to another external FW800 drive with two Seagate 200GB drives configured as a RAID stripe.
    It would be interesting to get some stats on how many people have their iTunes library on external or network drives and what vendors the drives are manufactured by.
    Post your iTunes config details here, even if you dont have the problem.

  • Audio playback stuttering using AirPlay under iOS 8

    I encountered a lot stuttering in audio playback with apples music app and Spotify using AirPlay mode with my AirPort express. It occurs not only in background use, but also when the apps are on top. Reseted all devices, nothing helped the issue. Very annoying, it never happend in the previous builds. I think it's a iOS 8 problem and hope Apple solves it soon. My internet works fine at 50 mbit though.

    I've contacted Apple Care lately, and though they where very nice and kind, they pretended to never have heard about the issue and claimed, it should work. they gave it to their developing engineers though. Let's wait and see...

  • Audio stuttering/ skipping in iTunes 10.1.1.4

    Updated the software, now audio is skipping ONLY when played through iTunes. Tried all the suggested fixes, uninstalled iT and qT twice and reinstalled, still have the problem. Anyone run into the same problem or have a potential solution?
    Thanks! Oh, running WinXP sp3

    Hi,
    I have a similar problem with music files 'stuttering' or 'jittering' and it's particularly noticeable during quieter tracks. Almost sounds like crackles or pops in the background.
    The interesting thing is that I played the same problematic files on the same machine using Windows Media Player and they were rock steady perfect!? Suggests to me an issue with the iTunes software. I was similarly tempted to reinstall iTunes and the audio drivers, but I see this didn't help another friend here with the same problem.
    Th eproblem has come about since I transferred all music to my new computer running Windows 7 64 bit and wonder if there is an issue with the latest iTunes 64 bit version software??
    Any thoughts/advice please? Regards.

  • Integrity of my music in itunes playback stutters & skips and has in all previous versions

    curently running itunes 10.6.1.7 on desktop. But in all previous versions I had the same problem, in about half of my library of music at the beginning of songs it stutters and skips, is as best I can explain what it is. but when I play the same songs in another player such as winamp I don't get this problem, I just tried to record the situation ( problem) and upload it to youtube and post the link here, but it's not doing it at the moment. weird.. well when it does i'm going to record it and post a link to it on youtube so that'll be the best way for readers of this thread to hear what I mean, but maybe Apple already knows theirs an issue with that.

    Are all your songs etc. still in the usual folder(s) on your computer? Try holding down the Shift key in Windows when opening iTunes. In the resulting dialogue you will get the option to create a new library or navigate to an existing one. The default location for your iTunes library is in C:\Documents and Settings\Username\My Documents\My Music\iTunes\ (or C:\Username\Music\iTunes\ in Vista). Look in there and see if you have more than one library file (they have the extension .itl) If you have more than one try opening them in turn, you may find your original library is still intact: How to open an alternate iTunes Library file

  • Installed iTunes 11.1.4 on Windows 8.1 and audio playback stutters then speeds up or stops.

    Is there a way to fix this?
    I can manage to get the audio files to playback normally when I run as Administrator & Windows XP SP3 Compatibility, but when I attempt to "Get Info" on a track the program will crash, so this is only a temporary fix.

    Well, after some messing around I solved the problem.
    Edit>Preferences>Playback>Play Audio Using: "Windows Audio Session" allows the files to playback normally.

  • Disc playback stuttering/skipping on some set top boxes; not others

    I have built a dvd in DVD Studio Pro 3, and it plays fine on my computer, small portable dvd player and my region free dvd player, but it stutters a lot on my older set top box I purchased back in the year 2000. I am using the default compression settings of 1 pass VBR 4 low 7 high, and encoded all audio and video previous to import using quicktime and apack. I am using Maxell ink jet printable DVDs that are version 2.0/8X-SPEED DVD-R Revision 3 and can be written 1X to 8X speed. The dvd consists mainly of motion menus that run from 30 seconds to 44 seconds (there are 82), with several short tracks, the longest of which is 3 minutes. This is a dvd menu design portfolio, so the menu complexity was the goal. Total disc size is 2.5 gb.
    Compressor won't install on my system so I had to compress each piece of video individually in quicktime...recompression would take 100 hours that I just don't have, and since I'm not sure the bit rate is the culprit (since the dvd plays fine in so many players) I am very reluctant to recompress all the video without knowing definitively that is my problem. I am considering trying some basic apple brand dvds, but don't know if the dvd media could be the problem. I saw on another post that Maxell is considered a reliable brand. I was wondering about dvd speed and compatibility, since the first dvds I bought were too new/too fast to play in any of the set top boxes, and only played on the brand new portable dvd player and in the computer. Any help/advice would be very much appreciated.

    I just realized that a few of the specs I posted are mistaken -- I was using the default settings in Apack to convert my aifs to ac3 and it is 448 kbps. They are only 2 channel ac3 files (no surround sound). You mentioned 192 kbps. I can't find any reference to acceptable ac3 settings in the manual. Is 448 too high?
    I also realized my mp2s are at the bit rate of 7.5, 5.5 rather than 7.0, 4.0 as I posted earlier.
    Do you think either audio compression or video compression could be the source of my problem? Does it make sense for higher compression to work fine on newer players and not on older ones?

  • Since installing iTunes 7.3, all audio playback on CD/DVD drive skips

    Hi,
    I am running Windows XP home edition, and have recently downloaded iTunes 7.3.
    Since installing iTunes, all audio playback via my CD/DVD skips/stutters. This occurs in all media playes, Windows Media, Sonic DVD etc. Audio files stored on the hard drive play back fine through these same programs. So far I have updated firmware and drivers for my CD/DVD drive and sound card.
    I have looked on this site and Dells, and cant find any solutions as to what the problem may be.
    Can anyone help?
    Cheers
    Aidan

    One thing you could try is to check your computer manufactures site to see if there is a firmware update for your CD drive.

  • Windows 7 (64bit)  itunes choppy stuttering audio playback

    Hi All,
    I'm new to these forums so apologise in advance if this topic has been covered already....
    I recently upgraded my Dell to Windows 7 64 bit and also upgraded iTunes/ QuickTime to the 64 bit version which resulted in audio playback in iTunes stuttering every few seconds. I waited for the latest release thinking it must be a bug which apple are addressing. Just installed it (ver. 10.1.056) but the problems is still there. I’ve tweaked quick time, installed the newest possible audio drivers, for my soundcard nothing makes any difference. If i use windows media player to play my music its absolutely fine , no stuttering , no problems at all. So why can't apple get their act together?
    Has anyone else experienced this problem or found a fix? if so please get in touch.
    Thanks for reading
    Dave

    I have a similar problem. I recently got a new laptop with Windows 7 64-Bit. I've started to rebuild my iTunes library and it was all going well. However, I noticed a lot of my files are starting to loop the first second or so of the intro for around 6 seconds before the song plays normally. At the time, I didn't think of this as a problem, but the exact same looping occurs on the iPod itself on the same files, at the same time, everytime.
    After deleting the broken files and getting new versions of the same songs, I decided to test them in Windows Media Player first and there was no intro looping. Assuming all was well, I added these files to iTunes, tidied up the song info, added album art and then played the tracks to see if the looping was still gone. Some of the tracks were fine, but others had developed the intro looping. Playing these same files in Windows Media Player again, after running them throgh iTunes, also now has the looping which it previously did not.
    iTunes seems to be destroying my files. Is there any way to fix this?

  • Audio and video playback stuttering...sometimes

    I'm having issues with audio and video playback stuttering at times in several applications. It's the same kind of skipping or stuttering in each application, whether it's iTunes (version 10) or YouTube or Netflix (Safari). I can also hear it when I'm just adjusting the volume via the keyboard, the "clicks" stutter.
    I'm not running anything other than iTunes and Safari at once, the iMac has 2 gbs of RAM, it's running Snow Leopard. It also will work sometimes for a while. I just can't figure out why it will work sometimes and not others. Any ideas about what the cause may be? Quicktime X have anything to do with it?

    video playback stuttering at times in several applications.
    Quicktime wouldn't work either.
    Until you max out your ram, you are pretty much stuck between a rock and a hard place.  In the meantime, make sure you have the latest versions of
    Adobe Flash Player
    Flip4Mac
    VLC Media Player
    Perian
    Movist
    I'm noticing that in general it's running extremely slowly now, even with only the browser running.
    Disconnect all peripherals from your computer. Boot from your install disc & run Repair Disk from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
    Select your language.
    Once on the desktop, select Utility in the menu bar.
    Select Disk Utility.
    Select the disk or volume in the list of disks and volumes, and then click First Aid.
    Click Repair Disk.
    Restart your computer when done.

  • Audio stuttering in Yosemite iTunes, Mavericks OK

    Ever since installing Yosemite, I've noticed a quite annoying problem: stuttering audio. I listen to music a lot and so iTunes has been the app that shows the problem the most. However, it's not as clear-cut as just playing audio on iTunes.
    I've been trying experiments over the last few weeks. I've used tools like top and Activity Monitor, trying to determine if something is taxing the CPU for a split-second or not. Unfortunately, I found no concrete evidence of this. It's random, and it's annoying.
    I've also quit all apps that could be causing it like Safari. The audio still stutters.
    Symptoms: music played on iTunes will randomly stutter for a fraction of a second. Like a hiccup.
    Tests:
    iTunes with low-quality audio (64kps). Happens sporadically.
    iTunes with high-quality audio (24/192, 24/96). Still happens sporadically, but no differently than low-quality audio. I thought maybe higher quality audio was taxing the system.
    Music is on an external thunderbolt My Book from Western Digital.
    Movies streamed from the same Thunderbolt drive do not have issues.
    Music played using Quicktime from the same Thunderbolt drive does not have issues.
    Music played using VLC from the same Thunderbold drive has issues, but not as often as playing through iTunes.
    Movies and music streamed to my AppleTV do not have problems when played from the same Thunderbolt drive.
    YouTube is OK. No stuttering at all.
    So, something seems to be happening with iTunes on Yosemite, and sometimes VLC.
    As a developer, I have a small partition for OS testing. I put Mavericks on there and copied some albums with high and low quality audio. Not a single stutter. Not one.
    So the problem has to be Yosemite. It's obviously the same computer (mid-2011 iMac, 20GB RAM, 3.7 GHz i7).
    I have no clue how to solve this problem. At first I thought it was some kind of Thunderbolt issue, but even with the Thunderbolt update it still happens, and doesn't happen at all with Quicktime.
    The only wildcard is the strange stuttering I get with VLC but I'm wondering if it's a red herring.
    So is it iTunes, or is there something wrong with the Yosemite sound system?
    What can I do to check something like this?

    Linc,
    I had not mentioned I already tried that, but when I tested it a few days ago, nothing came up in Console.
    Just now, I tested it again. It looks like some kind of problem between the Alesis Multimix 8 driver and Safari, but when I quit Safari a few weeks ago the problem still occurred. I just tried it now and it didn't happen. I did upgrade the Alesis driver a while ago and I don't remember if I tried the Safari test before or after that.
      Regardless, here's the dump. This does NOT happen every time there's a skip. In fact, nothing shows up in the log when there's a skip, but the dump below does show up when Safari is running.

  • ITunes 11.1.3 issues - freezing during audio playback.

    Like many other folks on here, I'm having some playback issues with iTunes 11.1.3.
    Macbook (couple years old) 2.4 mhz 2 core- 4 gigs ram
    We use this computer primarily for music playback for dance classes and performances. Have run dozens of shows over the last year or so with zero issues.
    There *might* be a better playback software option, but iTunes doesn't get in the way with too many options, has (up until now) been rock solid, and has never let us down, and is less prone to user error causing huge WHOOPS during something important.
    That is, until 11.1.3. Didn't really notice any issues at first, but wife came home from a dress rehearsal Wednesday evening and complained - "it froze a couple of times while playing back Act 1. What's wrong with my computer?". (Act 1 - approx 50 minutes of music - 40ish total cuts).
    I looked at it - she had a ton of other stuff running - mail - wifi - DVDPlayer - iPhoto - you name it. I figured that was the problem, shut all the other stuff off, and figured it was solved.
    Nope - I'm running audio during our final tech rehearsal this evening before performances start in the morning.
    35 or 40 minutes in - froze again during a track.
    It just stopped - buttons became unresponsive - beachball came up - we waited a minute - and then it freaked out while trying to catch up with anything I had pressed, skipped around a bit, then resumed acting normal again.
    Took a short break - checked nothing else was running that didn't need to be and made some adjustments:
    Wifi off
    Cloud off
    Check downloads, sync, podcasts ... all off.
    Reset all warnings. Reset cache ( which took a surprising amount of time)
    Match and Genius, off
    Opened Acitvity Monitor and stopped any processes that were not essential
    Reboot ....
    Another 30 or 40 minutes later - froze again.
    Luckily, the lighting guy had a PC laptop with him. I quickly authorized his computer, transferred everything, and the rest of the evening went without a glitch.
    Not sure what to do next. I'm pretty sure it's NOT the computer.
    Disk checks OK. All hardware test are OK.
    Couple of observations:
    1. If I repair permissions - it finds a TON of messed up (?) iTunes permissions and fixes them. One day later, it find just as many again. What's up with that?
    2. If I watch disk access in the Actiity monitor during playback - on occassion there's a WRITE spike. Odd. What's it writing? This is with NOTHING ELSE running but iTunes, which didn't glitch during the spike, but still, what's that? A contributing factor? A clue?
    3. CPU and memory use looked OK. Haven't managed to get it to glitch again while I'm actually watching this though.
    Between what I've tried, and what I've read here, I'm pretty convinced our Macbook isn't at fault here. I'm pretty sure there's a problem with 11.1.3
    If anybody has other observations or suggestions, I'l love to hear them.

    Are these recent releases?
    I had troubles right after iTunes 10 came out because Digital copies were misreading "10" as "1" since the version check script was only looking for a single digit version number. Newer releases shouldn't have this, but if it's more than two years old, it might do this.

  • Randomly Pausing Audio Playback/Restoring Question

    My iPhone 3G will on it's own, randomly pause audio playback (Pandora, iPod) when a 3.5 mm jack is plugged in, this takes any-wear from 10 secs to 30 mins, and this never happens when I use Apple OEM iPhone headphones. I went to an Apple store and the proposed resolution was to restore my iPhone as new. So my first question is: if I restore my iPhone as new, load music and a few apps on it and this does not fix the problem, can I restore my iPhone to the current state that has all my apps and data? My other question is, does anyone else have this problem?
    Thanks!
    -Mike

    I don't have this problem.
    But your question about restoring your phone to it's current state, yes. When you plug your iPhone into iTunes, right click on the phone in the column on the left and select "backup phone". (That is if iTunes doesn't automatically start syncing/backing up.) After that you perform a restore which erases the phones and updates to the current version. At that point, iTunes should prompt you to install the backup.

  • ITunes 11.0.4 playback stutters

    Hello,
    Since upgrading to the lastest version of iTunes, every 30 seconds or so the playback of audio tracks stutters like it does when the CPU is very high.
    However, this is not the case as it does it when only iTunes and nothing else is running. This is becoming very infuriating and would appreciate some pointers as it can't be anything serious. Hopefully it's just a buggy upgrade. I've re-installed iTunes, checked for soundcard driver updates to no avail.
    I'm on Windows 7 service pack 1 64-bit. Thanks in advance.

    Continuing the conversation with myself, I have created a new user account and tried to play some tunes there. On inital startup of iTunes in that account, no sound would play when playing a song in iTunes.  Playing songs in quicktime player or in the browser worked fine, but for the life of me I couldn't get sound to come out of iTunes for music files.  Tried a TV episode and that worked fine.
    So I nuked the prefs file for iTunes, and restarted.  Finally some sound from music files!  And I've now played 3 albums in iTunes in this account with no hangups in playback. 
    Now the question remains, what is wrong with my existing profile and do I try to fix it or do I move all my content into this new profile and forget about the old one?
