Sound is choppy

Since installing OS 10.5 and subsequently updating to 10.5.1 I have experienced choppy sound in all applications. VLC, DVD Player, Windows Media Player, iTunes, everything. And those apps that use sound skip because of the sound loading problem as well. I've repaired permissions, updated all that I can, restarted, cleared more HD space, etc. Has anyone else experienced this problem?

Hi,
This has happened to me, too, but not all the time. Originally, I thought that I had inadvertently caused it when I set QuickTime's "Movie Download Cache Size" to zero in System Preferences, but the choppiness is happening to me now, and I reset the QuickTime settings about a week ago. I also think that on one occurrence of the choppy sound, Spotlight was using a lot of CPU cycles to index my drive, but that's not happening now, either. If I find out anything more useful to control and/or cure this problem, I'll post back.

  • Please need help!! Voice sounds really choppy

    I HAVE A LIVE CAM VIDEO IM VF0350, I hooked up my mike and wanted to test the sound and hear a horrible choppy sound,
    Any one know what this might me caused from?

    Yeah, it might just be a playback thing, because a lot of audio can drag the speed down, and then the audio plays like it's in quicksand. If you have enough tape you should do a test export; meaning...export all 15 minutes of your project so far. And then watch it just to make sure the audio is still working.

  • Sound very choppy and out of sync on videos. Fine when playing music

    Whenever I try to play a video on iTunes I must use quicktime instead because the Audio makes it so unbearable. It becomes choppy and delayed by a few seconds. It almost pulses.
    My audio is fine when I try to play music and fine on quicktime.
    Anyone got any idea???
    Thanks

    Did you ever get an answer on this?  I have the exact same problem.  Windows Vista, iTunes 10.5.3.3
    Songs play great, videos are choppy and warble but they play fine on QuickTime.

  • Qpaeq - sound very choppy / delayed in some applications

    Seems to be a thing with Valve games (SDL?) and Mumble. Works fine otherwise. Can't seem to find any information on Google about the problem.
    Is pulseaudio-equalizer-gtk still around? Didn't have problems with that one.

  • Itunes Sounds Choppy, particularly when on the internet

    Hey there,
    Itunes all of a sudden sounds very choppy; jumpy, particularly when surfing the internet. Don't understand why; running latest Windows with intel core i7 processor and plenty of RAM so it shouldn't be an issue. Any help would be very greatly appreciated.
    Thanks in advance,
    P

    Try this alternate version:
    iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)
    which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases. Some users have found this eliminates the issue.

  • Satellite P100 - choppy sound from DVD and CD

    When playing a dvd or cd, the sound is choppy. When playing mp3, the sound is perfect. When playing a game, the sound is fine. What could this be from? I'm using a P-100 with WXP Home edition.
    Thanks for any suggestions!

  • Mac mini choppy sound

    hi ive got a problem with my mac mini mid 2009 model, when i plug some headphones in or external speaker into the audio output, the sound is choppy it sort of goes on then off very quickly with like 1sec intervals. its unlistenable. please help

    If you bought your mac second hand, you might not have got the install dvd that came with it. Your mac can boot from a dvd or external disk. If you have a mac friend he might be able to help you with that.
    When you boot from a clean system on a dvd you can eliminate problems caused by faulty files in the system software.
    The other possibility I can think of is hardware. Either in the circuitry or simply in the connector. The intermittent sound you describe does not indicate problems with the plug, but does it crackle if you wriggle the plug?
    If your mini has a HDMI plug, you can plug that into a tv and try if the sound is better that way.

  • Sound and Video are choppy when running on battery

    When I try to watch a DVD the video and sound is choppy or if I just listen to a CD or MP3 the sound is choppy.  I think that I set all of the power options to maximum performance while on battery but that did not seem to make a difference.  Can anyone please help me?
    Thanks

    I went through an annoying password reset process to post on here, haha, I was experiencing this issue and managed to resolve it for a flash animation I was making that was going to be sent out; thus fixing it for myself wouldn't change things for others. I know this is old, but if anyone is in this position, I hope it helps.
    I was using Swish Max for my scenario.
    Under the Export Settings, I found that by default it was using SWF Version: SWF8 - when it had the option to go up to SWF10. I changed it to 10, and set the hardware acceleration to Level 1 - Direct.
    I exported, and it still didn't work. The music was choppy as heck and terribly inconsistent with speed. I even created a preloader, which appeared to work but didn't resolve my issue.
    FINALLY, I kept it at version 10, and found that it had an option that said "Preload Content: Disabled." I set that to "At Preload Frame" and though I had a loading animation setup to do the preloading, I still placed a preloadcontent keyframe at frame 1. Then I set Hardware acceleration to Level 2-GPU and exported.
    IT WORKED. The terrible, seemingly non-fixable audio cracking lag was gone and it worked flawlessly.
    Hope this helps someone, I originally found this when I was trying to find a fix for the issue.

  • Distorted / choppy recorded sound with Audigy 2 ZS and Vista 64-bit

    Hi, I wonder if anybody has any idea of why this issue is happening. First let me give you my PC specs:
    CPU: AMD Phenom II X4 940 @ 3.0 GHz
    Mobo: Gigabyte GA-M57SLI-S4 rev. 2.0
    Graphics: 2 x BFG GeForce 8800 GT 52MB
    RAM: 4 x GB G.Skill PC6400 @ 800 MHz
    Sound: Creative SB Audigy 2 ZS
    TV Tuner:? Hauppauge WinTV PVC PCI II (26xxx)
    OS: Windows Vista Ultimate 64-bit SP
    ?So here's the deal. I have no problems whatsoever with audio playback with this sound card. The issue I am having is while recording sound with it. When I record my voice via a Microphone with the Windows Sound Recorder and then play it back, my voice sounds very choppy. It sounds as if I was talking in front of a fan. The same happens with any program I try to use. If I use Audacity to record sound, the playback is also distorted / choppy. The main problem is with Skype, as I cannot use it to talk to people because they cannot understand what I'm saying because of the issue. Does anybody has any ideas why this happens? My PC is a dual boot PC with Vista 64-bit and XP 32-bit, and this issue only happens with Vista. Sound recorded plays back fine under Windows XP.
    I am using the latest drivers available for this card from the Creative site.
    I'd appreciate your help,
    Daniel

    A little bit off topic here, but 64bit does not mean more performance at all lol.
    Sure, but there are in some cases drastic performence diferences. Under a fresh installed Vista X64 i have less CPU usage, as under 32 bit. But of course X64 uses more RAM (some tasks are double 32 and 64 bit).But the main reason I have more performence is, that the games I often play, get almost a boost. Dont ask me why, but under 64 bit EAW and FOC have the same FPS as under 32 bit. But under X64 I use a bit more Details and a higher resolution. (both are 32 bit games, so its a bit funy )?______________________?Sure there are other ways to install the drivers. But if some Setup dosent work, the first thing I try is to get it via Divice Management. And as this worked for me, I dont waste time to try other methods (Had bad experience, you can break the driver faster than install it *G*)?______________________?Some Questions I have left (after a few hours undr X64 with Creative Drivers):?Could it be, that the driver causes sometimes havy CPU usage?Could it also be, that the driver causes some lags, after you copy a file (the end sound, copy is finihed, but takes more time for "final finish", than without the drivers) - I know that Vista has some problems, on some PCs with copy, and that MS has an inoficial Patch (but dosent help for my PC so far)

  • Choppy Sound on video import

    I use a Sony HD Handycam to record video. During playback on the camera the sound and video is flawless. But when I import it into iMovie HD the sound is choppy and difficult to understand and the video playback is also choppy, almost like it's playing back at a higher speed than it was recorded.
    How do I solve this problem? HELP!

    Hi
    First thoughts:
    • Did You record in LP-mode (90min on a 60min tape) ? Don't
    And if it is so:
    Use same Camera + set iMovie pref to NOT import as individual clips
    • Free space on internal (start-up) hard disk less than 10Gb ?
    I try to have at least 25Gb free
    • Lot's of audio clips > 50 ?
    Mix down audio to one audio .aiff file
    • Other programs running in background
    Turn them off + Simple desktop back ground (not animated/changing)
    Turn off energy save
    Turn off screen saver
    Don't use "File Vault"

  • Airplay Mirroring sound choppy

    I have an AEBS running in radio mode 802.11n only (2.4GHz), and AppleTV (not the 1080p one) an iPad 2. All network devices are in my living room. My iPad is about 4 feet from both AEBS and AppleTV. When using Airplay mirroring, the sound is choppy. There is basically nothing else going on on the network. Any ideas?

    I'm having the same issue. The audio here also cuts comepletely out at times. Not good!

  • DVD Sound choppy with onboard sound

    Okay, I have this problem with playing any dvd's through any version of power DVD.
    With the onboard sound chip with the latest realtec drivers, any dvd (especially high fidelity funny enough) plays with the sound really choppy and nasty. If I switch to my second soundblaster soundcard, the sound is really perfect. So i'm just wondering what is causing the A97 chip to output choppy sound when playing dvd's, wheras normal mp3's play fine
    Thanks
    Dan

    Cant think of much though have you enabled DMA on your DVD drive?
    Because I had somany problems with my onboard sound card I went and got my self a creative live sound card.

  • Itunes + Gaming = choppy, scratchy, icky sound.

    I consider myself a proud owner of an ipod. I chose the best I could get imo for my listening pleasure. Up untill the latest itunes version I was pretty satisfied with itunes. I could easily buy new music without having to leave the home. I even bought some music after I upgraded. Now i'm also hooked on one of the best known MMORPGs.... before I had no trouble playing music while gaming. Yet since this last version It seems impossible to do so.
    I have a Soundblaster Audigy 2nx, (the usb thing with the 24bit sound). 5.1 surround. Before there was no trouble running my game and itunes together and still be able to listen to both the sounds. Now if I play my music in itunes without the game running, nothing happens. Even better: before I can even have the game running, switch to desktop open itunes play my music but !the moment! i switch to the game. The sounds gets choppy, scratchy, icky. And only the itunes part. The sounds within the game remains unaffected. I've tried all the solutions apple has handed to us users. 16-bit, 24-bit, stereo, 5.1, 44.1khz, 48khz, Lowering the sounds output of windows and raising the sounds output in itunes. ENABLING enhanced sound ( it was off to begin with on my comp), Turning on safe mode within quicktime prefs. All to no avail. Even tried looking for additional plugins which I had none...
    So can somebody plz confirm that they have no troubles playing music (newly bought, and bought before) untill they switch to a game (that uses direct sound of course) and the trouble starts there?
    I know apple is real handy in saying.... well u shouldn't use that game then.... NO, it worked before, I paid money for the songs I'm trying to play, I paid money for the ipod I have and that is the reason I use itunes. So plz fix it.
    So another topic to add to the endless list of problems

    I am having the same problem...yet the recorded music on the ipod sounds great. I just cant listen to any of the tunes while recording or just playing the cd. Its weird!
    I have reset the Ipod what a job, plus gone in and made some speaker changes etc;, but nothing seems to work, and then some times it will play perfectly.
    I have Windows Media, so naturally It opens when I put a cd in, so I have to turn it off on Mute and mute itunes and the it records great.
    Help, I would like to listen to music while downloading and working on the computer..So does anyone out there have the same problem and a fix?
    Thank YOU

  • Choppy sound on K7T Turbo2

    Putting together a new system for a friend.  It is based on the MSI K7T Turbo2 MB.   I am using the onboard sound.  But when I play back music or video, the sound is choppy.  It gets worse when I am doing things on system, like opening files or accessing programs.   When I do this, the sound goes into a "slow down mode" as if it does not have enough power to keep up - like it's losing resources.
    I am running windows XP pro with athlon xp1800 cpu and 256mb ram.
    Any suggestions?  I have tried three different drivers so far (one from windows, one from the cd, and one from the website).
    Any suggestions would be most helpfull!   Thanks!

    OK!  Just wanted to post back my findings.. as I tried some last few ditch efforts before replacing the board entirely.
    Just trying different things moving to hardware, since I didnt think it was software related at this point.  I was thinking hard drive, because of the slow down of the sound while doing other things.  I was thinking of replacing the hard drive and trying, but I thought I would change the IDE port.
    I moved the hard drive from IDE0 to IDE1 .. and low and behold!!!  Sound issue fixed!!!   Its flawless now.   Craziest thing I have ever seen!   I still don't know if IDE0 is a bad port or if the system just doesnt like IDE0.. but I dont care at this point.. it works.
    *shakes head*

    Welcome to the Apple Community.
    You must restore from a computer.
    Get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
    Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
    Connect the micro USB cable to the Apple TV and to your computer.
    Reconnect the power cable (only for Apple TV 3)
    Open iTunes.
    Select your Apple TV in the Source list, and then click Restore.
