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

  • 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.

  • 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.

  • 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.
    How do I troubleshoot and report problems with Flash Player Video?

  • Audio stuttering in generated MP4 file from Captivate 6

    I'm using Captivate 6.0.1.240 on a Windows 7 machine. I opened a project that I created in Captivate 5.5 and published the project to an MP4 file. This project is straightforward: I captured video, imported audio into the captured file, and then edited the file so the video and audio match up.
    The problem is that I get audio stuttering in the generated MP4 file. This problem doesn't occur when I preview the file within Captivate or when I generate an SWF file. I've implemented the potential solutions in this forum but so far nothing has worked. Since I'm viewing the MP4 file on my hard drive, bandwidth isn't an issue, either.
    My project is for an online course for RoboHelp, so I would prefer to use Adobe technologies to create the course. However, I can't do that if Captivate won't generate working MP4 files. I would be happy to share the output file so you can see what's happening. If you need any other information to solve this problem, please let me know.

    Hi, Anjaneai. The size of the generated MP4 file using the default settings is 115MB. However, as I said in my original message, I'm generating this file on my own hard drive so there aren't any bandwidth issues. I have noticed that the time it takes to generate the MP4 file takes significantly longer than the time Captivate originally estimates. For example, Captivate says the project file will take a little over 3 minutes to convert, but the actual time was a little less than one hour. I'm not sure if that's due to the fact that I was running Firefox and the associated Flash plugin at the same time.
    The audio is a separate object on the timeline. I simply added the audio within the Properties tab.
    I'm not sure what smaller resolution I should try. Please send a suggested setting (perhaps the lowest one?) and I'll regenerate it to see if that works.
    Thanks,

  • 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.)

  • Audio stuttering problems with certain exported MP4 files

    I'm currently running Captivate 6.1.0.319 on my old and decrepit Pentium 4 machine that has 4GB of RAM and is running Windows 7 SP1. I'm developing an online training course on RoboHelp 10 for Udemy, and they require all lecture files to be in MP4 format. Unfortunately, some of the MP4 files I generate from Captivate have audio stuttering starting a few seconds into the generated video and nothing I try fixes the problem.
    All the videos are being recorded with video dimensions of 1360 x 978 pixels. I import the .cptc file I recorded into the .cptx file, and then I import an MP4 audio file into the .cptx file. When I finish editing the .cptx file, I publish it to an MP4 file using the highest video settings and the highest variable bitrate audio settings.
    I have tried the following to try to fix the problem:
    Turned off SWF compression.
    Created a new .cptx file and copied the slide from the problem .cptx file into the new one, and published that new .cptx file.
    Disabled all software operating in the foreground and the background.
    Tried generating the MP4 file on my laptop; the laptop runs the same version of Captivate on Windows 8.
    As I said, Captivate generates some MP4 files perfectly without any stuttering, and others have the stuttering problem. If this problem sounds familiar, it's because I wrote a couple of messages about this a few months ago and despite some good suggestions, I wasn't able to solve the problem. I've spent my time during the past few months trying to find another program that will convert SWF files to one of the formats Udemy supports -- MP4, MOV, or FLV -- without success. Captivate exports to SWF and HTML5 format files without any trouble at all. But MP4 generation is spotty and I need to get this resolved so I can get this project off my plate and start making money off it.
    If you have any further questions, please let me know. I look forward to hearing your suggestions.
    Thanks,
    Eric Butow

    Hi,
    I am having the same issue and cannot figure out what is causing it, as it occurs randomly - but fairly frequently  - when I publish to mp4. And it is not tied to the project - seems to be something happening during the publishing. The issue might occur one time when pubishing a project and if republished again it may or may not occur again. I would be very interested in finding exactly what is causing this and any step that are tested and proven for getting away from the problem.

  • 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?

  • Two issues getting a headless error form windows & my clips audio plays in the preview but not once placed in th timeline. I taped with a panasonic HC 750 V. i believe it is with clips filmed using directed not surround audio.

    The title more or less says it all. I have Elements 13 & am Using the Panasonic HC 750V. I shot in AVCHD 1080/60p & instead of surround sound choose the directed feature to focus on the voices in front of me. The audio works in preview but not on the timeline. I am also getting Headless errors when working with premiere that pop up in windows but it does not shut down the system.
    Any help apprecaited.

    pc
    Have you updated your Premiere Elements 13 to 13.1 using an opened project's Help Menu/Update. If not, please do so.
    Just some points of clarification on the AVCHD 1080/60p with which you are having audio problem in Premiere Elements 13.
    a. I see no option to record to tape with your Panasonic model. Is there one? if not, what was recorded to, a memory card?
    b. When you talk about directed not surround audio, are you saying that your video uses Dolby Digital 2 channel stereo instead of 5.1 channel?
    c. Is your AVCHD footage presented to you as AVCHD.mts rather than AVCHD.mp4. I think that is the case if you are referring to Dolby Digital
    rather than AAC audio.
    Are you saying that you get play back video and audio if you double click the video's thumbnail in Project Assets, but you get video but no audio after you drag the file to the Timeline and play back its contents in the Edit area monitor?
    a. Have you checked the Volume control under the Adjust Tab/Adjustments Palette/Volume Panel expanded to make sure the Volume has been taken all the way down? Under that condition, you will get play back in the Preview Window, but no audio from the Timeline level play back in the Edit area monitor.
    b. In that same regard, if you look at the Timeline audio clip, note a yellow orange line that runs horizontally across the duration of the audio clip. Is that at the bottom of the frame or is it in the middle or at the top?
    Do you work with the Elements Organizer at all? That Headess issue sounds like an Elements Organizer issue. More on that later. That issue should not prevent you from continuing your work. But we will explore that next.
    Thanks.

  • 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:
