MacBook :: Audio Tearing Distortion - How To Solve It
Jan 9, 2010
Sometimes, while watching a streaming video on my Macbook, the audio begins stuttering and tearing (that's the best way I think to describe it). Pausing and refreshing the tab is useless, and, usually, closing and reopening the browser is equally useless. This problem is not limited to just one steaming site -- issues occur on Youtube, Hulu, Megavideo etc... For about ten minutes (though sometimes longer), the audio across all programs on my Macbook does not work properly until the problem mysteriously solves itself.

My MB started doing this really strange thing where the screen gets all weird and distorted when scrolling. There are photos to show what's going on.
I have 4GB of OWC memory installed, but this was happening before I installed that so I can kind of rule that out.
Has anyone else had this happen, or know what causes it. I've tried all of the usual fixes like a fresh Leopard install and combo updates.

I recently got my MBP and I noticed there's a issue with headphone audio distortion. When I plug in my earphone or headphone without any sound playing, there's a clear whining noise like zi zi zi sound which is really clear, sounds like old 80s radio noise. When I play the music, of course it was covered by the sound of music but it really bugs me out knowing that I cannot listen the pure sound of my music. The volume of this distortion noise would not change while I turn up or down the volume of my MBP. I asked someone professional, he said it's a famous issue of screen frequency disturbing audio in macbook pro.

whenever I'm listening to music or watching a video after a while the audio will drop out, stutter, or become horribly distorted. If I pause the video or music for a second then start playing it again the output will be okay for a few seconds to a few minutes then stutter again. If I leave it stuttering the output will either eventually go back to normal or just stay stuttering or muted. Once or twice I've got a 'you need to restart your computer' kernel panic error (log attached/linked to below) and twice my computer has seemingly randomly restarted itself.
I know it's not an issue with my connection as it happens on locally stored files as well as streaming media. I know it's not a hard drive issue as I've had the problem across two different hard drives (I used the Migration Assistant to swap my stuff from one HD to another, presumably bringing across whatever causes the problem). I've had it with two sets of RAM as well. It happens whatever web browser (for streaming media) or music/video player I use for local files. If I restart the computer I get a longer period of time before the stuttering starts, and it gets more frequent the longer I leave my computer running - a RAM issue maybe? These screengrabs where taken either during or shortly after the stuttering had taken place. This top output is after a particularly bad stutter: and here is a log following a kernel panic: [URL]

I have a Core Duo 2006 Macbook 2ghz, 2gb RAM, running 10.6.2 and whenever the CPU is taxed for an extended period of time, chances are I'll get some audio issues. What usually happens is that the audio will stutter for a second or so, then change instantly into a heavily distorted 'bitcrusher' output. The only way to resolve this is to restart whatever program is outputting audio. So far, this has happened in both Firefox & iTunes.

I'm having issues with audio distortion on my BLUE Snowball mic. This happened in GarageBand on my old MacBook running Leopard as well as my new MacBook Pro running Snow Leopard. I've tested mics, cables, and USB ports. Nothing is consistent.
I'm using 3 mics simultaneously. The distortion doesn't not occur in any predictable manner. Sometimes it's present from the start, while other times it doesn't happen until I'm halfway through my podcast. It's not clipping audio, more-so clicks and interference type noise. I've read some people saying there are often issues with audio drivers and USB, and others saying that it's because the power going to the mics from the USB port is dirty.

I have a 24" Intel iMac, with the latest version of Snow Leopard. I bought it last July and have AppleCare. For as long as I can remember I have this problem with it:
* Every 30 seconds, almost to the second, the audio from the built in speakers distorts and gets slightly louder. This lasts about half a second then goes back to normal
* It only manifests through the internal speakers, it's fine through headphones
* Rebooting makes it go away temporarily
* I've reset PRAM and SMC to no avail
* I've tried turning Time Machine off to no avail
* I've taken it into my local Apple Service Centre, they couldn't replicate the problem, it only seems to happen in my house (every room I've tried it in is the same)
* I bought an expensive power filter/conditioner, this hasn't helped at all

I'm having some weird screen tearing when I scroll via the trackpad (two fingers). It does not occur if I scroll with the up/down arrows. This occurs in all windows, including safari, mail, itunes, any windows that scroll.

I've been patiently waiting for a SU to fix the problem assuming that it is something that everyone is experiencing, but I finally decided to start looking around for a fix and am not seeing a lot of info about the problem.

Does anyone else have this problem? All the DVDs I put into the Super Drive have the edges torn up (i.e. they become jagged).

So, for the last week or so I'm been experiencing very strange symptoms, which I think are probably all connected:
1) My MBP (running 10.5.8 bought in August 2008) has from time to time just been turning itself off. Like, I'm just working on something and then it suddenly turns off.
2) My mouse from time to time stops responding to input, sometimes the keyboard does the same thing
3) When I restart after 1 or 2 occurs, it doesn't work. The computer turns on, I get to the screen with the apple on it (there's a chime all of that), then it goes to a plain blue screen and just stays there - the log in box never comes up.
4) In what I think may be related, my computer seems to be running extremely "hot" right now. After just normal use, I'm reaching GPU temperatures as high as 75 degrees according to iStat and CPU temps around 70.

I have used a Macbook Pro from 2007 and have now recently bought the all new 17 inch Macbook Pro.
Something that really annoys me (and my ears) in the new MBP is the crystal clear sound of the Macbook pro speakers when i hit the Volume up or down key on my keyboard. The sound is just too treble and so loud and it gets even worse when i put headphones on and turn down the volume its even more deafening.
Anyone think the same?
Is there a way to solve this problem?

My iMac suffers from some screen tearing during normal use, for example, YouTube videos. I also get some screen tearing when playing the Sims 3. However, it handles and plays large and HD video through iTunes and QuickTime fine.

what I imagined was a documented 8600GT nVidia issue with my SR MBP (purchased in April 2008 without Apple Care, d-oh), turns out to be a different issue altogether. The display gets distorted and it seems as if the LCD needs a v-sync controller. I have posted a video of it here[URL]. If I move the LCD slightly the distortion will go away. But it inevitably returns after a while. It gets unusable for that period of time. Oddly enough I can go hours without this problem manifesting, and then hours when this problem doesn't go away.
My recourse has been to connect an external monitor to the MBP, and it works great that way. So I am pretty convinced that it is an LCD/Cable issue as well. The Genius seemed to believe it was an LCD issue as well, something about the cable being torn or stretched or something. He quoted an amount ~$650 to get the whole assembly changed. Here's my dilemma: this is my work machine, and I can't afford to have it gone for a few days/week. Is there anything I can try at home before handing it to Apple for repair... like try and reseat the cable... I have opened the MBP in the past to replace the HDD. Should I even bother to get it repaired, if I can't fix it myself, or should I just save the money and get a new MBP?

I recently bought a 2010 Quad Core Mac Pro and I�m experiencing some serious screen tearing with games like FFXIV. I�m not sure if this has to do with my monitors refresh rate (8MS) or my graphics card (ATI5870). If you check my other threads you�ll notice that I�ve already been having graphic card issues. I�m running the game with Windows 7 64 bit through Boot camp and have all the latest ATI drivers.

Just got a new white MacBook yesterday (MB403LL/A) and have noticed, that depending on a slight change in viewing angle, pastel colors can get really distorted, even appearing as other colors, e.g., light green->gray and light orange to pink. One example would be Google calendar when editing an event. Looking at the screen in a normal position, the background appears gray, but when slumped down in my chair it looks green (the actual color). Is this a normal problem with MacBooks or could my display be defective? I took a couple snaps with iPhone that didn't turn out to hot but illustrate the point:

My two previous older macs have been perfect to me, but this new MBP I5 model is giving so many issues lately. Every once in a while, my computer's graphics (I am assuming) goes crazy, and I get this pixelated distortion that's right in the middle of my screen that's about 2"x5" on my 17" screen. This happened just earlier, while I was using Safari. However, even after closing all of the Safari windows down, the distortion will still be there, and will stay there regardless of what I have or don't have open. Logging in and out will fixes the problem, and everything goes back to normal for the mean time. Any one ever experience similar problems or know what I could do to see what's going or fix it?

I've just received a brand new MBP 15 i7 with high res. matte screen. Occasionally the screen becomes sort of distorted by red pixelated shadows that seem to depend on the current wallpaper, and also to some extent stay in the background when white background windows are opened. I have posted a picture taken by camera on Flickr, since a screenshot will not capture it. The funny thing is that I can make it disappear by closing the computer and reopen it again. I cannot force it to appear again though. Is it a driver problem? It doesn't appear on the startup splash screen or on secondary monitors. Here is the photo of the phenomenon: [URL]

I used boot camp to install windows 7 on my imac 10.6 and after it finishes installing the computer restarts and it'll just bring me back to the installer and when I eject the disc it brings me back up to osx without any way to go to windows. I can view the partition and it says that windows 7 is installed but I dont know how to get the windows 7. Every tutorial I see windows automatically boots up. I might just be missing something really simple, but its frustrating and I want to solve the issue

Since I updated to 10.6.6 I can no longer open my mail application. I get a message stating that "You have version 4.3 (1081/1082) of mail. It can not be used with the Mac OS X Version 10.6.6."
When I was updating my mail was not in the application folder but within a separate folder in the app folder, so it may not have been updated.
Now my question is how do I solve this, I can't work properly without the mail application!

I have made a movie on iMovie HD (using a Mac Book Pro) and have burned it onto DVD using iDVD. When I play the DVD on my TV or another iMac there is distortion during any rapid movement, e.g. a quick moving arm appears jagged and lined. There is also a slight blurriness to the general picture (the sound is faultless). Why this distortion is occurring?
