Audio stutters in playback

Hello,
After my ibook has been on for a while I get intermittent but fairly consistent stuttering in all audio playback (regardless of app). I'm running 10.2.8 w/classic active but can't seem to narrow it down to a conflict w/any other app. It usually takes some time to occur but once it's there, only a restart will resolve it (until it starts happening again).
I recently switched out my 256mb chip for a 512, but if the ram were the culprit wouldn't it happen right away?
Thanks in advance for any ideas

Thanks for the response and ideas Klaus,
I tried what you suggested but, unfortunately, the problem persisted. I'm fairly certain it's not an issue of inherent speed of my machine or its architecture or the os or version of quicktime. The same machine w/same system, playing the exact same types of mp3 files, has been working without these stutters for a long time, and nothing has changed w/my audio apps or the os. Also, the stuttering occurs on all and any audio app, even ones that I believe don't use quicktime (VLC etc...). This problem started only recently.
My hunch is that it could be a bottleneck of some sort or RAM or cache not letting go of or not flushing unnecessary data, or maybe a conflict w/an another app (though almost none are running when the problem crops up and the ones that are have been in use for a year or so w/out these problems).
So if I take the machine/speed out of the troubleshooting, I'm left to wonder if it could be the new RAM I installed. But, again, the stuttering doesn't happen right away and sometimes takes a day or so of the machine being on to start happening. but once it does, it doesn't go away until a restart.
**If it were faulty RAM, would the problem show up right away?
**Or is it a corrupt preference file somewhere, but, again, wouldn't that cause the problem to show up right away, too?
Thanks again

Experiencing lots of audio stutters / choppy playback

With Adobe Flash Player in Youtube I am experiencing lots of audio stutters / choppy playback. The problem started happening only recently and seems to be getting worse. I am running Flash Player 11.2.202.208 in Internet Explorer 8 on Windows XP (SP3) with a pentium 4. I cleared my internet history / cookies. I did a disk clean up and defrag. I tried uninstalling and reinstalling Flash Player, and also turning off hardware acceleration in Flash Player. What else can I do?
Thanks.

Hi Daniel,
I think the best approach at this point would be to gather system information and open a new bug report at bugbase.adobe.com. Could you take a look at the following FAQ and gather the info needed and open a new bug report? Once opened, please post back here with the bug URL.

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?

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

I'm noticing that in general it's running extremely slowly now, even with only the browser running.

Strange "Audio Stutters" in All Exports

Hello,
What I can only describe as "audio stutters" occur at seemingly random times in my Premiere Pro exports created with Media Encoder. They are very brief but noticeable intrusions that sound like glitches.
All audio sounds perfectly normal in Premiere; there are no problems on the timeline. I have tried the following troubleshooting steps:
Restarting the computer
Restarting the software
Cleaning Premiere's cache through the preferences panel
Changing the Renderer to "Mercury Playback Engine Software Only" in Media Encoder
Unchecking "Enable Parallel Encoding" in Media Encoder
These "stutters" occur in all exports; I have experimented with different projects stored on different drives, as well as with different formats (ie., H264 and Quicktime) and audio codecs (ie., AAC and MPEG).
The only way I have found to create an export WITHOUT "stutters" is by sending a sequence to Audition, creating a mixdown file, importing this file into Premiere, using it to replace the original audio, and then sending this single-audio-track sequence to Media Encoder.
I would love to be able to export from Premiere without having to run my audio through Audition. Any and all leads are welcome!
For your reference, I am running Premiere Pro CC on Windows 8.1, with a 3.60 GHz processor and 16 GB of RAM. I have 11 GB available for Adobe products. For what it's worth, I know for certain that I did not experience this problem prior to the 7.2 updates.
Thanks in advance!

Clearing the Cache is best done outside of PP using Windows Explorer. You can get the location of those files under Edit>Preferences>Media...
(On a side note, this Cache cleaning could use some improvement. Please add your vote. http://forums.adobe.com/thread/1369263?tstart=60)
If that changes nothing, it would be helpful if you could upload a file somewhere for us to hear the issue.

Movie audio stuttering

Since ITUNES last software update, Quicktime Movies (taken from my didital camera) which I convert to play on my ipod, play with the audio "stuttering". It is not an ipod problem, since the converted file stutters even when I play it back on my PC. I have some Quicktime files which I had conerted BEFORE the last update, and, they still play OK. However, If I convert them again with the latest software, the resulting file will stutter on playback.
I do see that the older converted files have a "BIT RATE" of 128 kbps while the most recently convert files have a bit rate of 94 kbps. This may be the problem....does anyone know how to set the bite rate for file conversion in Quick Time??

It is my experience that the DVD will also have the audio stuttering. I've had several projects with the same issue. It's frustrating. There is a thread that addresses the audio stutterning problem. I was not able to work around the problem on a video that I created. I will enclose the link:

4 stream Multicam stuttering in playback

I have a 4 stream multicam timeline with 1080/30P footage, 2 streams from XDCAM EX cameras and two from 5D Mark III's. Clip is 29 minutes long and after the first 4-5 minutes playback is stuttering regardless of where I have playback resolution set. I double checked that I was on Cuda render. I'm using an internal 7200 rpm drive with write speed at 150.5 MB/s and read speed at 179.1 MB/s. Any suggestions on how to remedy this rather annoying issue. If I pause and restart it will play for 5-10 seconds then starts stuttering again. Trashed preferences & restarted with no apparent effect.

You're right, I have changed the frame size and adjusted an inconsistency in settings (in one place, I had audio set to 44 GHZ). It's working fine in playback now, BUT I still have the problem in print to tape mode, audio stutters in different place every time.

Where else do you suggest I troubleshoot?

Audio Stuttering

We are experienceing a audio stuttering problem on playback. Very annoying. The ouputs are okay. It is just in the monitoring of audio. Any solutions? Thanks.
P.S. We are on a Mac and using AJA Kona 3 card.

I am experiencing the exact same problem on two brand new toshiba laptops.
Definitely wi-fi related, my problem goes away if I disable wi-fi - But it seems to be much better on some wireless networks than others - I suspected the security encription - I changed to WPA 2 from WPA and things seemed to get better - but then after a week it went back to being bad again.
Skype, CD, MP3 on the laptop, youtube - all give the problem
Did you have any luck on solving the problem?

How to fix stuttering song playback?

Over the past week, I began experiencing stuttering song playback in iTunes. I tried to lower the sound enhancement settings to no avail. Please help. System: XP Home, 32 bit.
Note: Am using iTunes 10.7 because I had problems with missing tracks and error messages in the most recent version of iTunes. Haven't had any other problems since the downgrade.

Hello Ayanna R
Verify that you have done some of the other steps in the article below to resolve issues with audio playback. The only other advice I can give is updating iTunes.

Audio stuttering in all browsers

I am having a constant issue with audio stuttering when playing videos, which has persisted for a couple of weeks now. This occurs in Firefox, Chrome and Internet Explorer.
I have tried downgrading to previous versions of Flash (including both 10.3 and a previous 11.X version), and (unless I am not doing this correctly) this has not fixed the issue.
I have even attempted to solve the problem by resetting Firefox, and then upgrading to the latest 15.0 beta, but this did not work as well.
Is there anything else I can do to resolve this issue, or is there something more fundamental broken with my machine? (I ask this as I have had problems with both Windows Update and a virus recently, and before these issues I did not have any problems with Flash playback.)
I am running Windows 7 on a Lenevo G570 laptop. I am currently using the latest version of Flash (11.3.300.268), and before I upgraded to the Firefox 15.0 beta I was using Firefox 14.1. (I believe that both Chrome and Internet Explorer are up to date, but I predominantly don't use these browsers.)

Stuttering flv playback issue- need help asap

We need help asap. Have a project is due to deliver today (5/14).
We have a video to go on a dvd-rom, live action with Motion Graphics behind.
When output is done thru Projector the Motion Graphics stutter as they scroll.
Here is more technical info:
Stuttering flv playback issue:
Prores 422 timeline 29.97fps 1280x720 output from fcp using current settings.
Mov file is approx 7gb, plays relatively smooth on a mac pro with no raid.
Frame by frame analysis shows all frames are present with no jumps tears or skips.
Tried several output paths, programs and settings to create a smooth flv file to no avail.
We adjusted data rates from 2k, 3.5k, 4k and 8k, no luck
We adjusted keyframe rates from low to all frames, no luck.
We tried cs3 flash encoder, cs5 media encoder, squeeze ect, same results.
Playback in the flash projector seems to choke slightly no matter what we do.
Have also posted in the Director Forum.
Any help much appreciated!

Here are a few ideas off the top of my head:
Try playing the file using a different xtra, sometimes different ones will work better. If you have Director 11.5, there is a native flv playback xtra.
You can build a player easily in Flash using the flvPlayback component, then bring that into Director as a swf.
Once you have the video in Director, try making the member Direct To Stage (DTS). If it is already DTS, try making it not DTS.
Make sure the video is not transparent, and nothing in Director overlaps the video... in fact, when the video is playing, nothing should be moving at all, and try to keep the amount of code that is running to a minimum.
Try lowering your video's data rate further or try using a different codec.
Using VBR (Variable Bit Rate) compression often makes the video appear to play smoother.
Try compressing the flv with different software. FFMpeg, for example, is free and does a very good job, often better than the Flash Video Encoder that comes with Flash/Creative Suite.

IDT HD Audio stuttering 3d apps/games/tf2 - Windows 7 x64 - Pavilion dv7-4113tx

As per the rules I need to state:
I am a HP employee, my views/opinions/etc are my own and do not represent those of HP.
This is cross-posted from freezes/lockups.
I would file some sort of bug report - but I wouldn't know where to start, I don't work in an area that has anything to do with manufacturing HP products; and this is my free time now and I don't have intranet access .
I recently picked up a HP Pavilion dv7-4113tx Entertainment Notebook PC [ XV780PA ] for my personal use and overall it's been pretty good. It comes with windows 7 Home Premium x64 bit.
there is however an issue that I must bring up in regard to gaming, or i would assume any intensive 3d application, most notably Valve games, my test of choice is Team Fortress 2.
The game will work fine in native resolution - I get around 100-120fps but about every 30 seconds - 2 minutes, there is a audio/video stutter (by stutter, it will repeat the last .5 seconds of audio about 3-4 times in a loop while the screen will freeze on where the first audio stutter started), which will cause the game to 'freeze' for approximately 2 seconds and then continue where you left off.
Team fortress 2 is an incredibly time critical multiplayer online game, and this delay essentially means my e-death on multiple occasions.
I initially thought it was the graphics card, or the drivers - I upgraded the drivers to the latest on the ATI site, that increased my fps, but the stuttering was still there. After searching around on the internet a bit, i found a suggestion to disable the audio driver (device manager lists it as - IDT High Definition Audio CODEC) as a test - so I did so.
The game purrs like a kitten - absolutely no stuttering. my score went up immediately
So, my next step was to try and get some Updated Drivers for the IDT Audio device (note, i cannot find a model name anywhere in the hp specs - or on the internet really) - I found out IDT themselves cannot release drivers, that these can only be obtained through OEMs.
which brings me to here.
now - the closest I have found to the drivers I required are here: IDT High-Definition (HD) Audio Driver for Microsoft Windows 7
Note: - it says on the page that they are 32 bit drivers - but I've found they work with the 64 bit version of windows.
these worked a little better - it fixed another annoying issue - the fact if you use the volume controls in a fullscreen application that it will switch back to the desktop to display the on screen slider bar of the volume going down (which was arguably redundant as windows 7 displays the speaker volume in the bottom right hand corner) - and it just turns the audio down as intended.
however - the stuttering is still very noticeably present .
I then tried to use the HP Support assistant to run automated diagnostics and troubleshoot... which then downloaded the old drivers that gave me that fullscreen volume control issue back again - so i assume the original drivers.
So I installed the other drivers again.
My next test will be to use an external USB or firewire soundcard to see if this will allow me have games with sound.
Can an appropriate agent at HP please address this concern and notify when this bug will be fixed - IDT says they work with OEM's to fix issues regularly on the IDT link above.
I believe this is such an issue that will likely require a bug fix.

Video/audio Stuttering on Macbook 13

Hi All
I have a mid 2007 Macbook 13 running OS X Lion 10.7.4. all up to date. Initially I had 4G's of ram ( I know it only reads 3 ) now I have it running on only 2.
Problem is video/audio stuttering when running movies. mostly netflix and or connected to a flat screen tv. on wireless or wired connection. but it also happens just running youtube videos or videos that I have on the system mostly in .AVI format. I could be running movies with VLC or quicktime and same ting. I've tried turning every running program off. like firewall, little snitch, sophos AV, etc. after turning them all off I do a restart. I have done permssion repair, checked the disk, run the daily scripts, even downgraded to SL to see if Lion was too much for the system and nothing. of of the 4G's of ram that I have. I swapped them to see if maybe one or 2 of them ware bad. when I install the operating system, I do a clean install. delete partition, format, the whole thing and bring it up to date. not all at one time. disk permissions repaired after each big updated. almost half the time the videos will run ok and than it starts stuttering. when is doing it. not even the mouse responds in those few seconds. is like something is grabbing all the system memory for a few seconds at a time. it has gotten to the point that the system completly frezzes and I get that black translusent window that says the system needs to be restarted.
I have about 40% free HD space.
Any ideas ?
Thanks

Welcome to Apple Support Communities.
The behavior you mention is typical of MacBooks with the GMA 950 video chipset and 64MB VRAM.
The best solution I've found is to quickly pause the video and let the video load completely before watching, IF the website allows it and will preload the content. Not all of them do. Some sites automatically buffer before they begin playing.
Watch in a window rather than full-screen.
Watch content on your MacBook screen rather than a HDTV.
The Safari Extension "ClickToFlash" lets you choose whether to load Flash content at all. It also allows 'preferring' H264/HTML5 web video content when available, and seems to be a bit better than simply defaulting to Flash content for every website.
I have a mid-2007 MacBook 2,1 with 4/3GB RAM. It is the very oldest model capable of supporting Lion. After reading of performance issues with these older systems in these forums, I chose to remain on Snow Leopard rather than upgrading to Lion. Snow Leopard runs most things I do very well in 3GB. Lion really seems to need 4GB and would like 8GB, from what I read here.
You don't mention how fast your internet connection is. A faster internet connection MIGHT help some. A wired Ethernet connection MIGHT offer a bit more throughput than WiFi. Worth trying out, especially if you have a friend with a faster connection where you can try before you pay to upgrade.
Ultimately we're talking about 5-year-old computers. That's "ancient" in computer life cycles, and the best solution (not most cost-effective) is a new(er) Mac. It's not a problem unique to Mac. Old Windows XP systems lack the performance of new hardware running 64-bit Windows 7.
New or recent Refurbs with 4GB or more RAM, faster video chipset, more VRAM, faster clock-speed, Intel "Sandy Bridge" (or "Ivy Bridge" likely coming soon) dual-core or quad-core processor, and, yes, a hefty pricetag to match. Anything else is at best a temporary measure to buy a bit of time (a year, maybe?) until you can purchase a new(er) faster better Mac.

Audio stutters with WRT54G v7.00.1

Hi all,
Last week I installed the Linksys WRT54G V.7 router. Since then, my audio stutters every 30 sec/minute . Music and movies just freeze for a second, than continue, 'till it happens again. When I disconnect from the router, everything works fine.
My router is also connected to a Xbox 360 (wired) and a Nintendo Wii (wireless, wifi). I've checked the security settings with the router's webutility, I use WPA2 AES, Beacon Interval: 50, Fragmentation Threshold: 2306, RTS Threshold: 2307.
I've tried for days, but nothing works. I have a Sound Blaster Live Value soundcard. Could anyone PLEASE help me?? I'm getting really annoyed. Thanks in advance.
Greetings,
Pater

Oh really? I forgot to mention. The computer having the audio problem has a wired connection with the router. Could it be affected by the wireless antenna's?
But I could try it. Won't this have a negative effect on my wireless connections (Nintendo Wii, Notebook)? Does it matter wether it's the left or right antenna?
I'm not at home at the moment, but tomorrow night I'll try your suggestion. I'll let you know, ok?
Thanks in advance.

Audio stutters in slideshow

Hello All,
I am a newbie with encore, trying to put together a slideshow with audio and subtitles. I used VBR mp3 encoded using iTunes. I rendered this slideshow and checked the preview to find that the audio stutters.
Any idea if encore doesn't like VBR mp3?
BTW, I will be glad if someone could explain what encore did by 'rendering'?
Thanks

In fact, I have most of the collection in VBR mp3 format only but I can still make AIFF files out of the CDs those are with me (and most of the collection is back home with parents)
Is there any way around to work with mp3 files like exporting to wav and using them etc? I am sure there will be a quality loss but is such thing possible?

Windows 8.1 Audio Stuttering

Since upgrading to 8.1 my computer's audio has been stuttering. For instance whenever I play music either on windows media player or on youtube etc, when doing an activity while its playing, the audio stutters.
Heres my specs:
Motherboard: Asus P8Z68-V lx
Processor: Intel(R) Core(TM) i5-3570K CPU @ 3.40 GHz 3.40 GHz
RAM: 4.00 GB
System type: 64-bit Operating System, x64 based processor
If more information is needed I can send the dxdiag file.

Hi,
Faced the same problem on updating my Dell XT2 from windows 7 64 Bit to Windows 8.1. As windows automatically installed its default HD audio drivers, I did not bother to use the actual chipset drivers that came along with the XT2. The audio used to stutter
very badly, especially when on Power Saver mode / Balanced mode and some other process would start. The stuttering reduced when I shifted to the High performance mode, but still took place randomly.
Just went to the dell site, downloaded the IDT drivers (A16) for windows 7 6 bit, and installed it in the compatibility mode. Hey presto, no stutter, even in the power saver mode!!!!
Enjoying my music. The issue is with the windows default drivers and the priority assigned to the task in the low power consumption modes. Try Installing the original drivers that came with the machine. Should resolve the issue
