Audio Stutters and Buzzing Caused by DPC Latency

Q: Audio Stutters and Buzzing Caused by DPC Latency

So, I downloaded LatencyMon as stated in threads concerning people with my same problem. The closest I got to finding someone with my same problem was when they were having problems with usb.sys or something or other, can't recall the exact filename. What makes my predicament tricky, or so I think, is that the problem is being caused by what seems to be a binary file within System32\drivers named DDDriver64Dcsa.sys and another was ACPI.sys, the former having the highest DPC routine execution time (501188) and the latter having the highest ISR routine execution time. (82.5)

From what I'm reading, I'm interpreting it that DDDriver64Dcsa.sys is the cause of my problems. I've disabled ACPI.sys and it has had no effect on the audio stutters. The good thing is that I know what to try next, the bad thing is that I don't know what to do with this other file. It is a binary file within some other package. Systemexplorer.net has it that "This file belongs to product Dell Diags Device Driver and was developed by company Dell Computer Corporation. This file has description DDDriver.sys." I'm a bit scared to just up and delete it, as I'm not entirely sure what it does.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: Audio Stutters and Buzzing Caused by DPC Latency

Amazing that I found this. Same exact issue. For about 3 days or so. DDDriver64Dcsa.sys seems to be the culprit but I am not sure how to proceed or exactly how to get rid of it.

This occurred today, Just after I had installed a copy of The Secret World, I was in a skype call and playing Dawn of war 2. I noticed the issue, but dismissed it as the computer was simply using too much CPU or something (I apologize, I am only just starting to get into the specifics with computers, sorta new). So I did the obvious, turn it off then on (via restart). Nothing changed, so I shrugged it off an played one game of League of Legends with minimal success not due to computer problems. I restarted after that with a manually scheduled Disk Check. Did it's thing for three hours, came back, messed around, still the stutter and buzzing. Did some fishing around on the net, did a sfc/scannow (don't know what that did), and uninstalled any background components to Norton and MacAfee if they weren't already gone, and updated my realtek codices.

One forum I read with similar symptoms suggested it was my motherboard going. I just want to be sure.

System stuff (it's also on my profile to the best of my abilities)
Computer: Dell XPS 15z
CPU: Intel Core i5 2401M
GFX: Intel(R) HD Graphics Family/ NVIDIA GeForce GT 525M
Motherboard: Dell 0XK6HV A00 (according to CPU-Z)
(I'd need help finding other stuff, but that's another forum issue :V)

P.S. Move this thread to a more appropriate area if it is necessary.

I have some serious audio issues that seems to point to some type of hardware or driver I recently installed. I have a lot of popping, cracking and stutters that actually make video playback stutter when it happens too. I play a lot of video games, it doesn't seem to impact games outside of having stutters and pops (i.e.: the game doesn't stutter or freeze like video).

I want to say this started happening when my machine mysteriously crashed a few weeks ago. My USB portable hard drive would cause Windows7 to hang on startup and would take 30 minutes to load Windows. After that time, I noticed my audio had broke it's drivers and I reinstalled new ones for an external sound card. I used the computer with the broken audio for another week and now I'm just getting tired of the issues. I assumed it was just with the sound card I was using, thus I removed the hardware and went back to onboard audio with my old Gigabyte Motherboard. However, the issues are still present even though I'm using a different audio source and utilizing different (REALTEK) drivers that are up-to-date.

My wife said she uninstalled some codec, but I have no idea what ones were uninstalled. I suspect that could be the issue, however my Catalysis Control Center for ATI is no longer working either. I assume my graphical drivers could be a cause as well. If not, I'm at a loss other than the recent memory I added. I put in 6 gigs of memory (2x 2gigs + 2x 1gigs) when of course, my 32bit Windows 7 Ultimate... Read more

Hi all, I've just bought a brand new Lenovo ThinkPad Edge E540, running Windows 7 Professional x64, and am experiencing such bad audio drop outs that listening to music is completely impossible.

I've done all of the standard changing power management options etc but to no avail. Here is a screen capture of the main offenders according to LatencyMon.

I guess the problem is with my drivers but as far as I know I have the latest drivers for everything. Really stuck on this and would appreciate some help, thank you.

A:Audio drop outs, probably caused by high DPC latency?

Much of that refers to networking and especially Wi-Fi. Wi-Fi is a known offender.

Pops/clicks/hesitation/dropouts are an often reported problem. Unfortunately there is no "one fix" for the problem. Each one has to be handled on its own. Its not all Lenovo's as I have a Lenovo ideapad and it does not have the problems you have. In fact I used my ideapad for on-site audio recording (I have a recording studio).

First thing to do is update all drivers that are available. Especially audio and video drivers. Along with Wi-Fi, they are two of the major causes. Check Lenovo for any updates.

Look at what is in startup and in the notification area. Many times programs in startup or in the notification area are not required and contribute to problems.

An unrelated item, you have the 64 bit OS but only 4GB of RAM. The main reason for a 64 bit OS is that it can address more than 4GB of RAM. In fact a 64 bit OS uses more of the available memory than a 32 bit OS thus leaving you less for programs. Consider upgrading the memory to at least 6GB (8 would be better).

Every once in a while, seemingly at random (could be playing a game, browsing the internet, sometimes just after start-up) I will hear a short burst of buzzing (not static) from my speakers. This happens for a second or two, stops for a second or two, and then starts again. Also, at the same time the buzzing is happening, my whole computer will stutter....the mouse will jump, the display will stutter, the whole computer seems to quickly freeze and unfreeze for a second or two, then be fine, then stutter again. Basically it makes it unusable.
The only "cure" Ive found so far is to just restart the computer, and it usually goes away.
Any ideas?

Not sure if I'm posting this in the right subforum - I've been having crackling/popping audio issues while playing games and using audio programs, and I've been trying to isolate the source/fix the problem, to no avail.

I ran LatencyMon for almost an entire day without really touching the computer or running any programs. Here are the results. Run on a Lenovo Thinkpad T530i.

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

I've been having trouble recently with audio clicking and popping, and I've traced it to high DPC latency caused by USBPORT.SYS, mostly during periods of high CPU usage but it also just seems to worsen over time. I've tried disabling non-core drivers one by one to attempt to find the culprit of this issue to no success and I'm at a loss for what to do next. I am unfortunately not the most tech savvy past what I've already attempted, so if there's information that you need from me to help press into this issue please feel free to request it, I'm just not sure what type of information I would have to provide.

This is a recent problem for me, my PC is only a year or so old and generally performs very well.

But just recently whenever I play a game, it randomly BSODs. It seems to happen mostly when there is some sort of cutscene or audio, although in the game I'm playing (Max Payne 3) there are more cutscenes than gameplay so it could be a coincidence. Basically it locks up, the screen freezes, and an awful grinding buzzing noise appears followed by a BSOD (uncorrectable hardware error). After rebooting, I copied the error information and it said this:

Hello all - hoping some real experts can shine a light on this one.

Installed a brand new mobo - Asus Sabertooth 990FX - and DPC latency checker was showing full red. Used Latency Mon to track down the culprit which was storport.sys. Searched everywhere for a driver update for storport in Win 7 and nothing exists.

Then went further and installed Windows Performance Toolkit and ran the Performance Analyzer to look at what was going on with storport. PA showed that the "RaidAdapterTimerDpcRoutine" was causing storport to spike so badly.

I'm not running any RAID drives - they're all set to AHCI in the BIOS, so I'm at a loss what to do next. All latest drivers & updates are installed. Are there RAID related drivers I can disable from device manager? Or switches in the registry?

Windows 7 x64 SP1
Asus Sabertooth 990FX mobo
AMD Phenom II X6 1090T black edition CPU
8gig ram


A:Very high DPC latency in Windows 7 x64 caused by storport.sys

Well I seem to have finally fixed my endless DPC problems. I performed a fresh install of Windows 7 and carefully installed all drivers and updates for everything in the following order:

- Asus motherboard drivers
- Flashed the BIOS and reinstalled latest vers.
- AMD CPU drivers
- All Windows 7 important updates incl SP1
- GPU drivers
- and lastly, the drivers for the external firewire audio device.

Hardware wise, I changed the slot that the GPU was installed on. I had it in PCI slot 3, and on reading the manual, they recommended slot 1 for the GPU. I also removed an Astrotek PCI firewire adapter card which was not being used. The new mobo has an external firewire slot that I've plugged into instead.

I also kept the driver installs "lean". Only installing the essentials. So I did not install the AI utilities for the Asus mobo, as I saw the AiCharger.sys misbehaving at one point. I also only installed the graphics drivers for the GPU - not PhysX, or 3D etc etc.

Something in that mix of changes was the secret sauce to fixing the DPC problems. Now I can run video, audio, flick between screens rapidly at any resolution and DPC never peaks above about 153. I've even still got aero running. I've got fingers and toes crossed that this remains stable, but this is the first time I've ever had Win 7 so calm since first installing it 18 months ago. I was never able to install and run my audio production software through Windows 7 due to these issues and had a dual boot mac... Read more

Iv'e had a set of good quality speakers for some years now. Just in the last week iv'e noticed they are buzzing but not loudly. I sounds much like a dial up tone (intermittent or continuous) and seem to only be active when something is buffering or downloading, any internet connectivity etc. The volume of the 'buzzing' isn't affected by increasing the volume and there has been no new wireless devices added to the house in that time.

Anyone have any idea what is causing this bizarre noise? Thank you

so I just got a new projector, and plugged it in to my headphones and computer. As soon as I put the headphones on, they were buzzing rather noticeably. I have done a bunch of searches on the internet and to troubleshoot the problem, and the solutions I saw on the other forums didn't work for me. I need to know if there is A box I can buy that is capable of isolating and removing the buzzing so I don't go insane. My headphones are some standard in-ear ones.

A:Speaker/headphone buzzing issues, caused by projector

If your connections aren't inserted all the way in, they won't make a clean connection and makes that "buzz".

Also, buzzing is more noticeable at high volume than it is low. Try checking volume controls on the projector.

Starting about a week ago whenever any audio is being played through my computer (speaker or headphone) I will hear a buzzing sound and occasionally the audio with skip. This happens weather I am playing audio that is being streamed from the internet or that is on my computer directly.

I have tried several things to fix this problem including installing all windows updates that are available as well as updating my audio drivers.

I am running windows 7 home premium 64 bit. My computer model is hp pavilion dv7t quad 6100 and I have IDT high definition audio codec driver version 6.10.6381.0 which my computer says is the latest driver version. Updating to this version has not solved the problem, however.

Any help with this problem would be greatly appreciated. If there is additional info that is neccesary, please let me know and I will post it.

A:IDT High Def Audio, buzzing sound when playing any sort of audio.

Unplug the speakers from the PC and see if you still get the buzz with headphones. Some "buzz" problems can be related to "AC power ground loop" problems if some separately powered devices are connected.

Noise and skipping are problems that have been posted here before. There is no "one fix" for that. There are possible hardware problems, drivers (including video drivers), Interrupt issues, Wi Fi caused, etc.

Skipping can be because the other device that is on the shared Interrupt that the sound is on is interrupting the sound. Sound is always on a shared interrupt (IRQ) with a higher priority device. You can try this: go to the Device Manager, RIGHT click on the entry for the IDT and then LEFT click "Uninstall". DO NOT check the box to uninstall the drivers. Then restart the PC and when Windows starts it will detect the sound and reinstall it and some times put it on a different shared IRQ.

I think the audio drive is to blame. Cause if it was brought from the cpu or processor , it will halt your audio system and you can hear nothing.

After having my motherboard, graphics card and RAM replaced due to a power surge, I have been experiencing high audio latency, along with very poor sound quality which includes static noise, crackling. The sound is similar to that of an untuned radio.
The sound quality is decent when I am running limited audio programs, but when I run multiple (Such as Skype + Youtube), the sound quality starts to become poor.
The sound quality also becomes poor quite frequently when I am only running one audio program.\

I've already tried going into Device manager and disabling/reenabling drivers to see if they were the cause of the problem.
I've also tried updating the drivers to the latest version.

Not really sure what to do now, help is appreciated gratefully.

Hi everyone!
I'm not sure if this is the right section to post this, since I'm not sure if my problem is hardware or software related, so please bear with me :)

I'm running Windows XP SP3, and I've been having a problem for several days now, where I can pretty much only run one slightly demanding program at a time.

The issue occurs whenever a program is actively running and I try running another one. What happens then is I get stutters at pretty much everything.
For example, running Mozilla Firefox goes smoothly, even with a lot of tabs open (say 12 tabs). If I minimize Firefox and run any game, however, the game's graphics and audio would both stutter and break every few seconds. I'd have to close the browser completely to run the game smoothly, and I'd still get such stutters during my anti-virus auto-update (I'm running Nod32, definitely the lightest AV out there).

Another example is I've been running a program update just now, and I see now that even my cursor's movement is broken, as well as any animation on screen in Firefox (be it flash or even a gif image).

The issue only started about a week back, and I haven't installed any new hardware or software. I've considered system restore but found it was turned off

I tried disabling a lot of the programs running in the background (now I only have Nod32 and Skype constantly running), and it still didn't solve the problem.

I'm not sure what to check and how, or even if this is an OS problem or a hardware ... Read more

"I have tons of stuff to back up"

Not bothering to make backups until you run into a situation where you might have to make them is sheer folly. What if the hard drive suddenly failed? You wouldn't even be able to make backups if that happened.

Try running the Disk Defragmenter on the C: drive

Consider having your system checked for performance-sapping malware (antivirus software cannot detect everything - you need specialised software which detects everything that's currently running on your PC.

And get those backups done while you're able to or one day you'll regret it.

I am having this really weird problem. Suppose I am watching a movie and a friend of mine decides to message me through google talk. Then for the time that gtalk goes "ting ting" the audio on the movie stutters, and as soon as the gtalk sound stops, it becomes normal. Now this specifically uccurs only with gtalk and gmail. I have played a movie and different music together and nothing happens, they both play normally.

Wonder whats wrong?


A:Audio stutters with gtalk

Three possible issues
driver issues (not that likely if able to have other multiple audio feed at once, bu possible)
If you are using x86 apps a x64 app simutaniously (gtalk being x86), can cause conflicts (this of course only applies if Win x64 installed)
Most likely candidate in your case is running short of memory. To check this, when noticing these issues, right-click on an empty area of taskbar and open Task Manager. Keep an eye on the memory levels. If running short, you may need to look at upgrading RAM, or as a quick fix,bumping up Virtual Memory.

This might be a hardware related problem but I decided to post it here as I'm not sure what the problem might be.

Recently I have installed a TPLINK TL-WN951N wireless adapter for our new internet. Now, when I stream videos in youtube or any other website, it often stutters.

What's even worse is that if I'm downloading something, this problem occurs much more often and happen also in games, movies and mp3 files in the harddrive.

This was not happening before installing the wireless adapter which makes me a bit suspicious. Before installing the adapter I did not have a high speed connection so it may also be a harddrive issue.

My specs are (the ones on my profile are old and I can't remember how to change them).

Win 7 professional 64 bit.
Intel I5 2500K 3.3Ghz + Overclocked to 4.5Ghz
4 gigs ram.
Asus Geforce GTX 560TI gfx card.

While downloading something, I monitored my cpu and ram usage and there is a huge spike in the cpu usage when the stuttering occurs.

The PC is quite new and has no performance issues except this issue which started happening after installing the TPLINK wireless adapter.

Any help on this issue is much appreciated. Thank you.

It stopped after about 2-3 minutes but after i had hit alt+f4 and ctrl+alt+delete, I then proceeded to play some Counter Strike : Global Offensive and In-Game my computer repeated the exact same process... It happened several times after that too. I restarted my computer and still it occurred, i updated my graphics drivers and it still is occurring. I also uninstalled Tune-Up Utilities 2012 and it still occurred. I do not want to re-install Windows 7 since i'm not sure where my disc is... I'm not even sure if it came with a disk since i got this laptop used.

Please any solutions or any help would be very helpful. Ask me any questions because i may have forgotten something in this post.

Recently, I have gotten an ASUS notebook as a gift and I've noticed that there is one big issue with it. Whenever I stream music from Spotify or watch a movie on Netflix, the audio begins to create a crackling static noise. The issue with the stuttering is whenever I have something playing in the background such as Spotify, whenever I begin to switch tabs or load a new site, the audio begins to stutter and mess up. I don't know what the problem is. I've tried updating my drivers. I've tried changing the default playback on my playback device as well but to no avail. My computer has the Realtek High Definition Audio driver. I have heard that Realtek drivers and ASUS machines don't usually function well together but I am not sure if that's the case. Any one know anything that might help?

A:Audio stutters and creates static

I have a desktop with an ASUS motherboard and RealTek and no problems. I have not seen any trend of RealTek problems with an Asus laptop.

One thing that is a know contributor to crackling/popping is Wi-Fi. If possible connect that using a wired internet connection and see if you have the same problems.

Another issue is other drivers (e.g. video).

Memory (amount) can be another possible issue.

Finally, sound is always on a shared Interrupt (IRQ) with a higher priority device and the higher priority device, in some cases, can cause interruptions in the audio (stuttering).

I have had my XPS for about 5 months and I have had some problems with it when trying to play games on it.
On many game such as Dead Island, Crysis, Command and Conquer Zero Hour, Killing Floor, Garrys Mod, Homeword 2 and maybe some others.  My system will usually play them without any problems for a while, and then, seemingly at random, the screen will freeze(not go black, just freezes), and the audio will stutter on what sounds like a 0.1 second loop.  This sometimes continues uninterrupted and also sometimes the screen will resume moving for about a half of a second, but then freeze again and the audio will start playing the game music as if nothing happened.
It never recovers however.  If I try to go to task manager and end the process,  then my computer will lock up and require a hard restart.
Sometimes it happens right when I start playing the games and sometimes I can play for an hour or two.
One interesting thing though.  My laptop never freezes on Runescape, IL Sturmovic 1946, and Dead Rising 2(DR2 is very graphically intensive).
This has been happening for about 3 months.  This did not happen when I first got my computer.

Currently I'm playing music on Google Play music which plays fine until I'm about to click on another page or go to the home of google play for example and it stutters for a few seconds.Also not sure if this is related, when I use my bluetooth speaker, audio stutters really bad, worse than when using internal speakers. Possibly two different problems but for now I really only care about the internal speakers stuttering as I rarely use my bluetooth speakers on my pc. Any hardware can be specified.

Dear all..

I have 2 issues with my computer that are really bothering my everyday computing usage..

OS - Windows 7 x64
? CPU:Q6600
? Video card Gigabyte GTX 460
? MB: Asus P5Q
? Power Supply: 550 Watt

*1st issue

My computer now gets BSOD randomly after I upgraded my video card from ATI 3850 to a NVIDIA GTX 460.. It doesn't crash in games, any games (I tried several games include SC2 beta, team fortress 2, and some others from steam), it only crashes under normal windows usage (browsing the web, youtube, music etc..)

I am pretty sure that the GTX 460 isn't defected as I have 2 GTX 460s, both of them crashed on this computer but both worked well on my other Vista computer.

I would be really appreciated for any helps...

Additional information about the problem:
BCCode: 10d
BCP1: 0000000000000008
BCP2: 0000057FF8DD4FD8
BCP3: 0000000000000003
OS Version: 6_1_7600
Service Pack: 0_0
Product: 256_1

*2nd issue

I have a Yamaha N8 firewire mixer/audio interface, I am getting a real weird problem that my audio (music, youtube, movies) stutters whenever there is internet traffic going on, stutter goes away if there's no traffics or if I disabled my lan card/wireless wifi card. (tried both, both of them stutters)
*this happens before I changed my video card.

Thank you all very much...!!

I have P50 thinkpad - I used it for home recording with very old USB audio interface - Presonus Audiobox.It is an old hardware - 10 yo or so but I had no major issues with it - apart from quality of D/A A/D convertersand latency problems when trying to use plaugins in DAW.Recently I upgraded audio interface to ZOOM U44. It is USB 2.0 based - fairly new (2yo or so ) technology.You can clearly hear the difference in converter quality. However to my utter dismay I cannot get U44 towork with P50 at all. The simplest tack of playing MP3s with U44 set as playback device results in audiohaving constant "hiccups" - every 5-10 secs it halts and skips. I unplugged everything, reinstalled U44 driver,tried every port on P50 (they are all USB 3.0) and the result is the same - does not matter if I use DAW orjust MP3 player. I have no such issue with AudioBox - playback is flawless. How can I solve it?

For about the past 2 weeks I started having a very annoying and strange problem watching videos and listening to any music files on my computer. When watching streaming internet videos, at random moments, for example, for 2 seconds in a 15 minute clip, a loud audio/video stutter will occur, even when the video has completely buffered, if someone is in the middle of saying something one syllable will be repeated 3-5 times, video will hitch, and then things will continue on as normal. At first I thought it was just on one site but its happening on multiple sites, in both flash and divx players, both of which I have up to date.
Now I don't think its even an internet issue, because its happening with video and music files I have on both internal and external hard drives. At seemingly random intervals the video will hitch, a syllable of dialogue will stutter, for 2-4 seconds, and then things will continue on. I have a new Gateway laptop that is running Windows Vista Home Premium 64-bit SP1. It has Intel Pentium Dual CPU T3400 @2.16ghz and 4GB of RAM.
I didn't have any of these issues prior to the last few weeks. I have broadband wireless internet, and other computers on the network play media files fine. I have kept up with windows updates, run regular malware bytes scans that have come up empty, and everything else is running fine and normal so I don't think its any sort of virus or malware causing this. The only significant system change I've made in this re... Read more

A:Video&Audio Stutters Online&Offline in Vista


Read other 2 answers

Win 7, 8 gigs ram, dual core. 
When I have several tracks up and want to listen to one of the tracks and edit it, (using Cakewalk Sonar X3) the audio stutters and video gets jerky also. 
Question is: Would that situation be helped by going to a SSD hybrid drive? 
Is the CPU just too slow to keep up? It's audio at 24 bits 96,000 samples per second. And maybe 4 tracks. Is that too much for a CPU to keep up with? There is no video. That is about 9.2 megabits per second to deal with. What would be the major slowdown here? 
When I get through, say, adding a track, the audio comes out fine, it is just in the editing process while listening to a track and recording another that the audio stutters but it ends up ok, the stuttering audio is not recorded, the result is fine.

A:audio/video stutters/lags when moving mouse

Depending on the wireless keyboard and mouse those devices may be the problem and not the PC. I have a desktop, with an i7 CPU and had similar problems with a Logitech keyboard/mouse unit. I returned those devices to the store and exchanged for a Microsoft wireless keyboard and mouse and no more problems.

So here's my problem

When I watch YouTube videos I get random stutters where the sound skips. The image doesn't seem to freeze though, just the sound

I also get issues with the sound streaming music online, where it pauses for a second and stutters even though it's not buffering.

When this happens, NT Kernel & System shoots up in task manager and uses more CPU than the browser. This by the way happens in every browser, IE, Chrome or Firefox.

It doesn't happen when playing music in iTunes or watching videos from my hard drive.

That being said I'm not posting about a buffering type stutter, I am aware of that and this is not it. This is like basically suddenly the computer has a big spike in memory or cpu usage and the video/sound clip stutters for a sec. But it happens often enough to be very annoying. In a 15 min YouTube clip it happened 10 times.

I have reinstalled my IDT High Definition Codec and my Intel HD Graphics 4000 driver, but still the problem persists.

Any thoughts of what I can do?

A:Sound stutters when streaming video or audio online.

Try this test: Start a Youtube video and immediately hit the pause button. Watch the movement of the red progress bar until it fully loads the video. This obviously eliminates any buffering issues if the problem is still there when you try to play the video this way. You might also want to do a speed test on you internet connection. Here are my results:

Now, I know you are convinced that it is absolutely not a buffering issue and you have done nice testing to that end; however, I would still try the tests as described above. Good luck.

A:Computer runs slow and audio skips and stutters

Please post more detailed specs and or the model of the computer along with the Operating System. More problem details might help as well. If your computer is running slow and sounds are stuttering a program(s) might be using most of your processor. Which could be anything, from an unwanted program to a virus, so please add more details.

@Forum ADMIN: Please delete the previous thread. The subject line is incomplete.

Hello everyone,

I'm new to the forum and this is my first post. I have been having a nagging problem with my Thinkpad R500 for a little over a week now.

Audio playback in iTunes (and other players such as Winamp) stumbles and stutters whenever I open a webpage or basically if there's any kind of bandwidth activity on - it's becoming pretty damn unbearable to say the least!

I checked to see if it might be an issue with the WLAN connection by hooking it up directly to the router by means of a network cable, but the issues persists.

I tried searching on the web and other forums, but couldn't really find a solution.

Any hints/advice would be greatly appreciated!

Yesterday afternoon, I was playing Grand Theft Auto IV on my PC and while I was in-game, the sound started to crackle and slow down and then suddenly turned off (sound only). I was still able to play the game without any issues but there was no sound!

I exited to Desktop (Windows 7 SP1) and there was NO SOUND AT ALL! Nothing made the sound work. I had to reboot the computer and then the sound came back but after a couple of minutes, again, the sound stopped working. This time, I was NOT playing any game, I was just surfing the web!

I rebooted again and then went to YouTube and tried playing a video; the video played like slow-motion (couple of FPS) and there was no sound again!

After another reboot, I tried playing a video I had on my computer using Windows Media Player. It played fine for a couple of minutes and then it started to stutter/lag (like slow-motion) and the sound the cut-off!

I can't figure out what caused this issue and I'm not sure how to go about fixing this!

Please help! This is so frustrating I can't use my PC because there is no sound and I can't view/watch any videos!

I've been having several issues with GTA IV (missing textures etc.) so I completely removed/uninstalled the game and ran CC Cleaner to remove any traces of the game. I also updated all of my drivers (there was a Windows 7 update yesterday so that might have caused it (?)) and checked Device Manager to make sure nothing was out of sync. I also checked Task Manager to see if ... Read more

A:Audio Stopped Working and Video Stutters/Lags! -HELP!-

BUMP! Someone help!

Read other 4 answers

My computer takes 3 minutes to shut down. Also, it occasionally has problems where the audio stutters, and the only way I can fix this is by restarting. Unfortunately, it takes the computer 3 minutes to shut down, and probably a little over 1 minute to start. A few weeks ago, it took 15 seconds to shut down, and about 6 seconds to start up. This is a Windows 8.1 computer. I am not sure if the audio problem is the computer, or the speakers/headphones. I do think it is the computer, though.
Anybody have any ideas on how I can fix this?

I have the exact same computer as you and even the exact same monitor, with all the same specs. I've also had this computer only 2 months.. and I'm having the same troubles as you. The audio randomly goes laggy and glitchy and sounds so strange through my speakers. Got no idea how to fix it but I'm probably going to take it back to the store if I can't fix it.

When I'm loading Civ 5, Sims 3 and Sims 2, I can hear loud buzzing/screeching form inside my case. It only occurs when first loading the games, not like when I'm actually in a household in Sims or moving units in Civ, and stops if I bring up another window when they're loading. As soon as a switch back to their window, though, the sounds start again. I'm well above required and recommended specs for the games that cause the buzzing, and I had the same problem on my old computer, which was also above recommended specs. Is my onboard sound trying to play some of the game's audio? Or is it just some weird error I have to deal with?

A:Audio buzzing during certain games

Check to see if your hard drive is mounted securely. Your hard drive will be under increased load when first loading games.

hi, When i record audio the timing is out on each track! ranging from almost bang on to about quarter of a second. Sometimes it can be almost on time for 5 or 6 tracks then a big jump to quarter of a second. I've tried different programs (cubase, ntrack, sonar, etc) but the same problem excists in all. i have been talking to cakewalk about this and nothing they have told me does any good. ive tried changing all the settings (under audio) and changed drivers, even reformatted xp with fresh install but no luck.


I have come to the conclusion that it must be hardware related. (i think)
