Audio and Video Stuttering since update to Lion

Hi all,
since updating to Lion my macbook has had the issue that when you play any kind of sound or video whether it be itunes or streaming online, the sound cuts in and out and video cuts in and out. Is anyone else having this issue? Does anyone have any suggestion to fix this problem?
Thanks.

Okay, so I've tried it while unplugging my laptop and using VLC Media Player instead and that seems to work. The only hangup I have while plugging it back in to charge is that I get tiling like what you see on a cable box.
Surely there has to be a way to where I can watch movies feasibly on my laptop without having to unplug it.

QT audio and video stutters in WinXP - IE7 and Firefox - DSL

Every time I click on an audio or video link on a webpage, QT Player opens to play the file. However, every file it opens - audio or video - stutters in a specific pattern. Each segment (chunk, packet, whatever the unit term is) repeats four times before the next one begins. This renders all files unplayable. Reinstalling has not solved the problem. I'm running the latest updated version of the QTPlayer. I don't know the number, but it updated last night, 3/9/2007.
Anybody have a solution?

Yosemite issues with Airplay (audio and video stuttering)

I have two very annoying issues with Airplay after upgrading to OS Yosemite (these issues were non-existent with the OS Maverciks) -
1. Periods of Image and audio stuttering lasting approximately 20 seconds, coming on and off at regular and frequent intervals,
2. It is virtually impossible to disconnect the airplay from the Apple TV by selecting "disconnect airplay display" - one needs to restart the machine to disconnect.
The configuration I am using includes the latest release of Apple TV (with latest software), the latest Airport Extreme (with latest software) and the 2013 iMac with the latest OS - Yosemite. I would like to reiterate there was no image and video choppiness / stuttering issue with Macericks. A serach for the stuttering issue shows it was reported by other users as well (following upgrade to the official Yosemite) and was first reported by a number of users during the beta testing of Yosemite.
I would appreciate your advice how to fix the issue.

Hold down the menu and down buttons on the apple TV remote for 6 seconds. It worked for me.
I must admit to be getting a little tired of finding workarounds to Apple's glitches. I now spend hours searching the net to find out how to get their products to do what they say they will.
Remember when things just worked?

Audio Fails in Games since update to Lion

I'm running the most recent version of Lion to date on my iMac. Whenever I log into games, the audio fails either immediately or after a few moments. Specific games are Fallen Earth and Heroes of Newerth. Sound is fine elsewhere. I read on one of the game forums something about updated API with Lion being the issue, but I am clueless. Is there any help out there?

Hi John
The following outlines the downgrade process:
http://appletoolbox.com/2010/10/how-to-downgrade-itunes-10-0-1-to-itunes-10-0-ge t-genius-sidebar-back/
(FYI: I had to do the "recreate library" step.)
I did not notice the inter-channel level difference you speak of, but clearly something is not right
so who knows what the various impacts might be and how they might manifest themselves
in different setups ...

Streamed audio stuttering since update to Yosemite

I have a big problem with stuttering streamed audio and video (Spotify, Deezer, Netflix etc) since I updated to Yosemite. It seems to get much worse when the stream in question is not the "active" thing on my screen. For example when the screen goes black due to standby mode when listening to Spotify or when surfing on one tab while listening on Deezer on another. Also, while watching Netflix on another screen with the laptop lid closed, it doesn't take long before the audio and video becomes off sync. Does anyone else have this problem or have any idea on a solution?
I have a Macbook air 13" mid 2012 and 100 mbit connection. I completely erased the hard drive before installing OS X Yosemite.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Why, after three months of apple tv working perfectly fine, is it now cutting out constantly and the audio and video out of sinc?!@

Why, after three months of apple tv working perfectly fine, is it now cutting out constantly and the audio and video out of sinc?

Playing rentals, Netflix, from local iTunes, other?
Firstly restart router and AppleTv after unpowering to see if that helps - may or may not but quick and easy to try.
Connection via ethernet or wifi? If wifi are there any new devices in the house which may be causing interference or new neighbouring networks? If feasible try to eliminate wifi issues by using an ethernet connection.

Updated FCP 5.1 to 5.1.2 - Audio and video now out of sync

I just noticed in my software update that FCP needed to be updated. So I updated the program.
Now when I open exisiting projects the audio and video are out of sync even though they appear perfectly in sync in the timeline. Has anyone else had this problem? The problem also persists when cutting clips in the timeline. I will use the razor tool to make the cut and I cut the clip on a ceratain frame in the timeline and then in the viewer the clip was really cuts a second or two later. Does anyone know what is going on?
Very furstrating to say the least. Any help is much appreciated.
Thanks,
Clay

I am still wondering why you're recommending that I use an external drive for this project.
Because the internal has more than enough to do running Mac OS X and the applications. It is constantly writing files. While DV video is at the lower end of the scale, it is still asking a lot of the drive's read and write head.
I always used external drives, but we had many problems with delays and processing problems.
At the very least, you should be using FireWire external drives. USB is no good for video as it delivers data in packets, not the sustained stream that video needs. The drives must also be formatted as Mac OS Extended. Windows FAT 16 of FAT 32 formatted drives have file size limits of 2 and 4 GB respectively. Anything larger is segemented and can cause problems on a Mac.

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.
Repair permissions after you reach the desktop-http://docs.info.apple.com/article.html?artnum=25751 and restart your computer.

Hi Richmoller51,
Welcome to Apple Support Communities.
See this article for some troubleshooting steps that can help with video playback in iTunes or Quicktime:

Stuttering audio and video

Hi
I have iMovie 4 - I am creating a very short video using 2 audio files and edited video footage with altered (sped up) speed. As soon as I sped the speed up to the fastest setting, both audio and video stutter like crazy. Its imperitave that the video is played this fast. This happens when I play it in iMovie, open the quicktime file saved in iMovie and play it in iDVD. Your help would be appreciated.
Many thanks
Emily

Well it momentarily fixed itself and actually burnt the DVD - which you were right - worked perfectly smoothly - sans stutter.
HOWEVER later when I had burnt all my projects onto DVD and deleted them to free space, the ibook went crazy!
Firstly it wouldnt detect any external devices - DVDs CDs or USB pens. Then it wouldnt save anything onto the HD saying that there was no space - a total lie - Id just trashed (and emptied out) about 20GB of video! Then it gave out completely - only a blue screen when I turned it on.
Took it to local Macrepair - they said the Hard Drive had gone completely - would cost about 300 quid to fix. With all the work Ive had done on that machine I figured it was better to start over and got myself a shiny new Macbook - fingers crossed for this one eh? If it gives out in 3 years time Im making the move back to PC - which is sad because I love the style of Mac. At the end of the day though it all comes down to performance and durability I guess.

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

Audio and video sticking and jumping after installing windows 8.1

Hello,
I have a HP Pavilion G6 - 2292sa
The product no is C1Y93EA#ABU
I have recently upgraded my system from windows 8 to the windows 8.1 update. Since I updated my audio won't work properly at all. During random intervals when playing songs on itunes the song will jump and stick for a few seconds then continue playing with random jumps like this throught all the songs. When I watch a music video on youtube the audio does the same thing as it does in itunes as well as the video sticking and jumping. I have tried an audio fix I saw on the HP forums that suggested I delete the hd audio driver, hard reset then reinstall them but this didn't have any affect what so ever. This is a huge problem since I can't watch netflix, listen to songs or pretty much do anything media related.
Any help you could give would be really apreciated.

Hi Greum,
Welcome to the HP Forums!
I would like to take a moment and thank you for using the forum, it is a great place to find answers. For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I see that after updating to Windows 8.1 your audio and video sticks or jumps and you have been unable to resolve it. You have tried uninstalling and reinstalling the audio driver to no avail.
I suggest you run The HP Support Assistant to look for updates and help resolve issues. You also have a built in troubleshooter in Windows 8 and 8.1.
Press the Windows key +C to open charms
Type troubleshoot audio/video and press enter

Photo Booth Audio and Video not in sync!

I am a YouTube musician. When I go to record I find it easiest to use the video feature in Photo Booth. However, ever since I upgraded to Mountain Lion my audio and video in my videos has been off of one another. They start off together but by the end of the video the audio is ahead of the video. When I went to try and see where it messes up I found that the video jumps frames creating almost a transition effect. I don't know how to fix this and would really like your help!

Audio And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.

Photo Booth Audio and Video are out of sync?

Hi. So there is this glitch that when I take videos on Photo Booth the audio and video are out of sync. This started after I upgraded to Mountain Lion, and since I use Photo Booth a lot, I really do care. Is there anyway that I can fix this until Apple fixes this bug? Thanks.
Extra Info: The first video I took was not out of sync, but after that they got more and more out of sync.

I've read all the forums. It's a big problem for most Photobooth users, Apple acknowledges it, but does not yet have a fix.
The best solution I have come up with is to dump Photobooth (I know - it was a great program, wasn't it? But so was Hypercard) and use Quicktime to make videos. You'll have to spend a little more work savings or exporting, but at least Quicktime is free.
Just open Quicktime Player and under the File menu you'll see "Record New Movie."
The downward slide continues...
