Audio Crackling In Game (DPC Latency)?
Jun 28, 2012
Recently the sound from my speakers has started to crackle when I am in a game and also when a UAC window pops up. I have used DPC Latency Checker and seen that when the audio crackles, the latency is very high. This screenshot shows the results of a UAC window popping up and being closed at the point when the bars are red.I was hoping it would resolve when I re-installed windows 7 and updated my drivers but the crackling still persists. By checking DPC latency when some devices were disabled in Device Manager one by one, I noticed that without my graphics card (nVidia GeForce GTS 250 512MB) driver installed, the audio crackling and latency was gone.

I just recently received a new dell xps 9100 loaded with an intel I7 six core 930 processor, 16 gigs of ram, 2x1tb hardrives, soundblaster x-fi soundcard, ati radeon 5870 1gb video card and a few other goodies. when im listening to my music while running other applications it starts to crackle and pop and drops in quality drastically. I have tried installing a new soundcard, installed new drivers, changed the power settings and its still doing th e same thing. I am running windows 7 64 as well. The dell technician has even been here and tried to resolve the issue with no success. with the headphones on as well it still does the same thing.

i was forced to perform a system restore today, and i restored to what i had about 6 days ago, when my audio was working fine. now, everything sounds like crap, with a bunch of electronic crackling on Internet and windows 7 sounds. i tried to reinstall my motherboard audio drivers, but i'm not sure where to extract the files.

When using the WMC I have noticed crackling sounds when playing m2ts video files containing AVC and AC-3. I have noticed crackling sounds primarily on start up of the video file and sporadically during playback. At first I thought it might be a hw issue but now I'm not so sure. BTW the video playback appears to be okay...just a problem with the audio.
On the windows sw side I am fully up to date i.e. with Windows 7 HP x64.
On the hardware side I have updated by video and audio drivers to the latest...in fact all the drivers are upto date. The Machine is an Acer Aspire X1470 desktop model with 4 GB of ram. AMD Radeon HD 6410D Graphics (display adapter). AMD A4-3400 APU.
I have tried connecting the audio thru the on-board sound system. I've also tried using an external USB based sound I/F. Which one I use makes no difference...The crackling still comes thru.
Part of the reason I'm led to believe this is not strickly a hw issue is because I've tried playing these same files with XBMC and they play cleanly. So it would seem there is some kind of interaction issue hw and sw when using WMC on this computer. BTW I've tried using WMP (my preferred choice) but the audio and video degradation is markedly worse than WMC. I've included the Media info data for one of the files I've played below:

I'm having an issue with my audio that is driving me up a wall. I'm having that (apparently common) issue of crackling/popping/static-y audio on a Realtek chip. I've tried multiple drivers, from Realtek official to Generic to Vista ones. My latency graph has little to no spiking too! (A problem most people identified in the previous megathread). I know this is a solvable issue because previously I've had it under control. It was just so long ago and I've forgotten.[code] Bios, video card, and OS are up to date. If you need any other information I can get it.

Testplatform HP Pavilion DV-5 Entertainment Notebook PC (4GB RAM, 2GHz dual-core) with Microsoft® Windows® 7 7048 x64 and Creative Sound Blaster X-Fi Surround 5.1.Driver:USB_W7DRVBETA_US_1_01_0091.exe. Tested with clean installed OS and only this driver.The Sound Blaster X-Fi Surround 5.1 is connected with optical TOSlink to a 5.1 Pioneer reciever. There occures great (and increasing) latency while playback of videofiles.-Sound will very noticably loose sync from video within a minute (all filetypes, not a codec problem). The latency will not occure with the internal notebook speakers, nor on same system with Microsoft® Windows® Vista x86. The Notebook ships with HPs "AMD USB Filter Driver" that should improve the performance of USB accessories, such as USB speakers or a USB TV tuner. I have tried to install this also on the testplatform to resolve the problem, however even though it seems to install fine the latency/syncproblem still resists.

Have been optimizing my windows 7 alot recently, i always do it when i reformat as it runs alot more efficient. Something i never did though was get my latency down. I had an issue were my latency was spiking to 1700, so i uninstalled my network driver and that brought my ping down alot, it spikes as high as 160 roughly. Is that fine for gaming or should i expect alot less? I have done the ping fix and other various tweaks to my nextwork and that seems to be the lowest i can get it.

I've been having DPC latency problems lately. It seems as if the latency ONLY spikes when using the internet. That's it. I play music in the Media Player; latency is fine, sound is fine. I play Halo and the sound is fine. I don't get it. Does the internet effect the latency? It only spikes when I'm watching a video or listening to music while online.

Recently I upgraded my computer hardware to a new motherboard, graphics card and processor. I moved my old hard disks (from my old hardware) into this new computer, turned it on and it started right up, I just had to re-validate Windows 7, which went without a hitch.Yesterday, I bought a new headset and started using it with my PC (before I was using desktop speakers), however, when I turned on some music, I was hearing a lot of stuttering/static while it was playing. I had this problem before, but it usually only happened when there was a program running that was taxing the CPU, and that isn't an issue now.I read around for a while last night about the issue, and it turns out that it's something called "DPC Latency", so I downloaded all the tools and tried to troubleshoot it for a few hours before I went to bed with no luck.So far I've tried:
-disabling HPET in bios & switching it to 64 bit mode (it was on 32 previously)
-turning off Powermizer on the Nvidia card
-disabling all USB ports one by one
-disabling all audio and network drivers
-changing the power settings for the CPU and HDD (tried this http://www.sevenforums.com/tutoria [...] -dipm.html
-updated all my drivers except by BIOS so far (I haven't tried that because it seems kind of risky, but I suppose I would do it as a last resort)
Another issue I was having was with my processor making this high pitched whistling noise, but when I turn off "disable processor idle" in the Windows power management area, it stops making noise. The weird thing to me is, it changes my dpclat.exe from full red bars to this for about 1-3 minutes (but after a few minutes it just goes back to full red bars, 28000μs):Before I went to bed last night, I turned on a 2 hour audio track and set it to loop with LatencyMon running. You can see in the screenshot below that the main culprits are:
-ndis.sys
-ataport.sys
-usbport.sys
-dxgkrnl.sys
-HDAudBus.sys
I've looked around on how to fix these individually, but I can't come up with anything at all. If I purchase a PCI sound card, would it fix these issues? I would prefer to fix it without having to do that, but if that's the only way to fix it for sure I can do it.

I'm looking to buy new DDR3 memory but I am totally puzzled by the CAS Latency and the numbers.It seems like the difference between a stick of DDR3 with 11 11 11 and 7 7 7 is only measured in nanoseconds, so how would the end user, we humans actually notice the difference between these specifications, or in fact can we at all.

My memory: MXD3C13334GS :: Memory :: Products :: Mach Xtreme Technology
There is no note on the stick upon the memory sticks; Right now the CL is 9-9-9-24 (auto in bios)
Is there anyway to find out whats the true CL ?
I know that bad voltage settings may cause a bad mem test and BSODS. wrong CL settings may have a similar effect ?

Can someone do a speedtest using the server in New York, NY?I've been getting an latency error everytime. Other servers work fine and the one in New York worked before. It's the one that's nearest my house, so that's what I generally use.

After about 24 hours of booting my computer, I have seen my DPC Latency spike tremendously. At first, I thought this was an issue with my network card (since disabling it would drop DPC Latency), so I bought a new card. The problem didn't go away, so I realized it was something else. High DPC Latency is a problem since it causes audio and video lag.
As I troubleshooted the issue, I have realized the spikes were caused from network activity. For example, when I am seeding [not necessarily uploading] many torrents or am loading a website, it shoots up.
Does anyone know what may cause this and how I could prevent it?

I downloaded the DPC Latency checker and I've been getting a lot of spikes. When I open my laptop and start the checker, it's all green; but as soon as I open Chrome or Firefox it starts to spike. It's spiking as I'm typing this. It's reached 65,795. I've disabled devices to try and find the cause but I can't figure it out.

Recently I've bought the Roccat Kave gaming headset and to enjoy it ( i would not say to the fullest but at least the bass ) I bought along a Creative SB X-fi Titanium PCI-e sound card. It was all fine untill a couple days ago, where I started to feel distortion and crackling sounds when listening to anything on the computer. It is not from the headset because it works just fine when connected to the audio tray on the motherboard

a couple of weeks ago i bought and downloaded a copy of the "aos system optimizer" and after using it to 'optimize' my system it instead screwed it up big time... now my sound crackles and stutters when i play all media, online or offline, dvds, Internet, games, etc.technical support from them didn't solve my problem, needless to say i've asked for( and gotten) a refund from them, but i'm still stuck with this annoying problem..i've tried the usual methods, such as rolling back drivers, uninstalling all the audio drivers (nvidia and realtek) restarting and letting windows 7 reinstall them, all to no avail.

ive been revieving some stutter noticibly when playing and form of video or audio and it has been getting worse as of late. Overall performance has dropped as well.Ive tried using Latency Checker and Latencymon and Realtek Ethernet Diagnostics Utility to try and diagnose the problem and the closest thing ive come to is that it has something to do with 'Realtek PCIe GBE Family Controller' as when I disable it the stutter appears to vanish and latency readings drop however I need that to connect to the internet so keeping it removed is not really an option.I have tried using a variety of drivers and methods from this forum and others and none have come to be of any use as of yet.

I received my copy of Windows 7 Home Premium. I skipped the Vista bandwagon, so I was moving directly from Windows XP Service Pack 3 (32-bit) to Windows 7 Home Premium. I opted to install the 64-bit version of Windows 7, as I had no issues when running the 64-bit beta.
As it turns out, I seem to have encountered an issue with my network adapter on Windows 7. Using any speed test site, such as speedtest.net, I get an extremely high ping (500ms +). I have tested another machine behind my router running Windows XP and there is no problem. Also, on the speed.io website, which tests connections per minute, I can only get around 200 on Windows 7, whereas I could get 2000+ on Windows XP with the same hardware.
Strangely, in games like Counter-Strike: Source, my ping is normal and in the 25-60 range on most nearby servers. Also, when running the ping command from the command prompt, most servers return a result lower than 100ms ... which is also normal. So, I don't understand why on speedtest.net, pingtest.net, and dslreport's flash speed test.. I get a ridiculous ping time of 500+ms. Web browsing does seem to be slow as well, as images take longer to load then they should.
I'm not sure whether this is a driver issue, or what. I have tried disabling both my firewall and AV software, so they are not at fault. I've tried 3 different version of the drivers for my NIC. One from the Gigabyte website, and two from Realtek's website (they released an updated version yesterday). My motherboard is a Gigabyte GA-EP45-UD3R (rev 1.1). I have all of my system specs listed on my profile if anyone needs to know more.

I am really stuck, basically what is happening is I am getting a crackling noise from my speakers and headphones on windows 7, it is not my sound card as I use a separate usb card for the headphones meaning this cant be a problem with the drivers as they are both using different ones right? Windows 7 was basically my version of vista, vista worked perfectly for me, I just don't know what is going on and it has me annoyed as i invest a lot in my audio just to have the os crap on it.

how can I play a video in jet audio (or any other media program) on one monitor while I play a fullscreen game on the other. I can get it to work with streams off of website like own3d.tv and twitch.tv, and I can even run the streams in full screen. However when I try to run a movie through jet audio or even just play music through zune player, they freeze up. The audio will still come through, but either the picture is frozen in place or the zune player seems to get frozen.

We are having ongoing problems with Windows 7 and mapped drive latency on our network. Our environment is as follows:Multiple servers running Windows 2008 & 2008 R2, some VMware servers (including our file server). Windows 7 x64 came preloaded on a brand new Lenovo think-pad, 4gb memory. This occurs on 4 different laptops. This problem ALSO occurs in exactly the same way on an HP Compaq x64 desktop running Windows 7 32. All systems are fully patched & up to date on SP's. Running IP 4 & 6 on all servers & Windows 7 machines Connected to GB Cisco switch.We run login scripts via GPOs that map drives (with net use commands) to 3 shares on our file-server, drives G, H and S.A fourth mapped drive to an IBM I-series does NOT experience these issues.
In Windows Explorer, mapped drives may or may not appear with red X's, but when clicked on they hang with a spinner and the green bar at the top of Explorer begins to run. This occurs randomly, but usually not right after boot up. It can take over a minute to complete. Also, in Word, which has references to these drives in file locations, file opening and saves can be very slow as it attempts to access these shares.This issue has delayed our roll out of Windows 7.Its unacceptably slow and cannot be used in a production environment.We have tried every suggestion we can find on the Internet:Turned off auto-tuning, indexing, thumbnails, set auto-disconnect to the max (both 99999 and ffffffff). Server & clients. No luck. Changed properties on the mapped drives to optimize for documents...no change.Changes setting on the network cards to disable flow control, set static link speed & duplex. Network drivers have been updated. Even tried using our wireless network and disabling wired connection...no change.All bios and hardware updates are completed...no change.Turned on and off network discovery..no change.
Disabled SMB2 on servers & clients...no change.Disabled firewalls, and unloaded antivirus (Trend)...no change.Safe boot with networking & clean boot with no services other than Microsoft...no change.

My sound is acting strange since i've installed Windows 7. (Ex-Vista user). It's making static/crackling sounds when I listen to music, or play games anything that makes sounds is getting disturbed by some kind of interrupting sound that makes crackling sounds..
Things I've tried:
1. I tried switching the cables (bought new ones)
2. I tried different speakers
3. I tried 2 different headphones
4. I tried cleaning my computer (dust)
5. I tried to get rid of any disturbing devices (phones, radios)
6. I tried uninstalling my device (HD audio device) and test it, and reinstall it, and test it again
7. I tried a reset boot (holding button for few seconds)
8. I got rid of my webcam it contained a microphone.

I have been dealing with this problem for a long time but something gotta happen. The random restart happen well randomly during idle, game play, surfing the web or anything that has to do with the computer. One minute I'm enjoying myself and the next I see the Dell logo. No BSOD just loads back to desktop. I have searched the forums and have nothing out there that gives ME and idea of what's going on. I have formatted and reinstalled the OS and it still happens. It happened before and After I upgraded my PSU and Graphics card. It's happens multiple times a day. Now my second issue. I have I play AION and during game play I hear a LOAD crackle through my speakers and I'll hear it for a range of 2 sec to 10 sec and then the system restarts. No BSOD on report. This also happened before and after new PSU and graphics card and before and after format reinstall. I've updated my graphics card sound card, Bios, chipset, everything I can find a driver for I've installed it. I cant find any resolution. I doubt this forum will have an answer for this problem but while I'm listing my problems I'll add this one. During gameplay of AION I will get a message that AION game client OTCbuildclient32_wogg(30) has stopped working. I have also gotten a couple alerts from Norton that that same process is using a lot of memory.

i'm using the onboard sound card for my Gigabyte GA-X58A-UD3R Rev 2.0 mobo.The sound chipset is Realtek ALC889. I've updated the latest drivers, but there is crackling/static noise when I play music.Currently I mainly use a 2.1 speaker system. But Ive tried testing it with headphones the static/crackling noises persists.It is not constant, but it shows up periodically. Furthermore, when there is no music/sound playing the noise is not there. This leads me to believe its a hardware/driver issue and not so much a speaker/interference issue.

When I install a game in Windows 7 and Windows recognizes it it dumps the game's shortcut in the Game folder of the Start Menu. That wouldn't be a problem except Windows 7 prevents the game from creating the shortcuts it would have created had the operating system not been Windows 7- things like the game's Read Me, Uninstaller & Configuration options.
