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, 28000ÎĽs):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:
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.
Testplatform HP Pavilion DV-5 Entertainment Notebook PC (4GB RAM, 2GHz dual-core) with MicrosoftĂ‚® WindowsĂ‚® 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 MicrosoftĂ‚® WindowsĂ‚® 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 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'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.
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.
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.
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.
Since Jan-Feb of this year I have encountered the following issue while trying to play games on my laptop.
Abnormally High CPU Usage Extremely low FPS - After 5-20 Mins of play. Extremely High latency to servers - from 300 - 900 after 5 - 20 mins of play.
The thing is all of these started 1 year after I been using this laptop, after a full year of everything running flawlessly all these issues kicked in after I performed a clean install in Jan., I even performed one in Feb. and one 3 weeks ago
Here are my specs:
OS Name Microsoft Windows 7 Home Premium Version 6.1.7600 Build 7600 System Manufacturer Dell Inc. System Model Studio 1558 Processor Intel(R) Core(TM) i5 CPU M 520 @ 2.40GHz, 2400 Mhz, 2 Core(s), 4 Logical Processor(s) Installed Physical Memory (RAM) 4.00 GB Name ATI Mobility Radeon HD 5400 Series Adapter Description ATI Mobility Radeon HD 5400 Series Adapter RAM 1.00 GB (1,073,741,824 bytes)
the sound is crappier than ever. I have this quality loss for a while but now is repulsive. Ive reinstall windows 7, reinstall relatek drivers, get ones specified by my motherboad manufacturer, tried the latest ones.... put power management at high performance...etc my motherboard ASUS - Motherboards- ASUS P5GC-MX/1333
as stated in the subject, I am unable to hear any sound from my speakers since upgrading to the windows 7 64 bit. I followed the other post that I found on this but I still cannot hear any sound.I have a dell inspiron 531. The hardware ids from the device manager areHDAUDIOFUNC_01&VEN_10EC&DEV_0888&SUBSYS_1028020E&REV_1000 HDAUDIOFUNC_01&VEN_10EC&DEV_0888&SUBSYS_1028020EI have installed the realtek drivers and they as working but I still get nothing but a slight hiss from my speakers. I have tried them on my laptop and they work fine.Does anybody know what might be causing this? I am half tempted to get a new sound card but I am reluctant as it says my existing one is working (it just seems to have forgotten to tell the speakers!) If anybody knows a fix for this I really would be eternally grateful
I've solved my gaming graphics issues, namely by choosing the parts I wanted rather than buying yet another "Media-Center"-style all-in-one unit that did everything, but not very well, I'm now in need of a solution to my present awful headphone sound quality. I have a generic Creative Labs Sound Blaster X-Fi Xtreme Audio card that is not very good, sound-wise, and, because it doesn't even include an optical out plug, goes unused. I purchased a refurbished Turtle Beach headset w/DSS decoder, and, while it works as advertised, the headphones are terrible for music. I've replaced the TB Headset with a much better-sounding Pyle set, and will buy some "real" headphones as soon as I've determined that the source itself is sending out a good-sounding signal.I've seen pro and con arguments about sound cards, like the Xonar series that have headphone amplification included. My issue with that is I am more concerned with the graphics for games, and I've built this system with SLI (another gtx580) in mind, and I do not see enough room under or in between the dual GPUs for proper installation of such huge sound cards, though I'm glad to have my ignorance in this area demonstrated. The anti-Sound card group seems to be gravitating towards a separate headphone amplifier, and I"ve seen them from the $20 dollar model included free with another headset I purchased, to the $1800 tube amps. I think I would like to either go this route, or purchase a home stereo receiver that can output the PC sound, thus having both satisfactory amplification for low-volume music listening( or ear-bleeding levels, if desired) and the ability to power speakers elsewhere. I guess what I'm asking is for some entry-level priced PC headphone amplifiers to start off with. I see countless rating comments for the FiiO series, and while the prices are certainly attractive, the fact that they're so low-priced also makes me leery of their actual amplification abilities while staying neutral in tone.
Why when watching Live TV in media center does muting the sound there mute all of Windows sounds? Would like to be able to mute TV sound, use close captions but still have windows sound function for other programs.

Using a tuner card in my computer. When I mute the sound in Media Center Live TV, it mutes all the Windows sound. Would like to be able to mute the Live TV & run closed captioning while keeping all the other Windows sounds. Can't seem to find any options to set.
I just bought a new pc from Dell. I opted out of buying the SB sound card they had as an option and now I am sorta regretting that. I loaded RC 7100 as soon as I got the machine and after going through this forum I am sorta left with the impression that SB cards don't work with Win 7. Is that really the case?
I was looking at an "Sound Blaster X-Fi Titanium Sound Card" but if it will just cause me grief it's not worth it. Does anyone have a suggestion as to what I can get and not pull my hair out trying to get it to work? The main game I play sounds sorta mediocre with the on-board sound.

I'm experiencing a strange sound in windows navigation start sound if i play that file in a media player it works fine but sometimes this odd sound appears in windows navigation start sound.I've ran malwarebytes (no issues), sfc scannow (no issues).I'm running on board sound card.
Yesterday I installed a new external hard drive - following the installation - my sound no longer played through my television (video is fine, HDMI connection) and sound now comes ONLY through the laptop speakers.The option for HDMI Audio doesn't appear in the 'sound' menus. I have 'checked' "shoe disabled" and "show disconnected" in those menus. [code] I use my HD TV as my primary monitor for gaming, so having sound through laptop speakers and not TV is quite annoying.Perhaps my only solution is another sound card?
I'm in a pickle with my machine and Windows 7 after this latest update. On startup I get an error from MMDevApi.dll saying that it might not run on Windows or... something else. This also occurs anytime a program tries to use the sound card ie. WoW, Yahoo IM, Live IM, SL, etc. I've updated my sound card drivers to the newest ones. I still get an error that says the device is detected when going to "Sound Devices" in the control panel.
Trying to adjust the sounds themselves leads me to the Windows Audio thing... which won't start even from the component list.
normally i only have 1 sound card/sound device in sound settings when i use hdmi with my tv, i have 2 sound devices in there, and i can choose 1 one of them as default, and all applications i run will play sound on that default device, so i choose hdmi (my tv) as default, open chrome for my mom watch movies, sound play on my tv (hdmi), that's what i want and i open firefox, go to Internet, sound also play on my tv (hdmi), that's not what i want, i want it (firefox) to play sound on my pc, so my mom can watch movies on tv, and i can watch Internet on pc
is there a way to do this? a way to set per-application sound card/sound device setting? i know some programs like windows media player or vlc can let you choose sound card, but firefox, chrome do not. i tried indievolume and it did not work, even uninstalled, reinstalled but did not work, or is there any browser that let me choose sound card setting (like wmp and vlc, but these 2 are not browser)
and does anyone know if mac or windows 8 has this feature as built-in? if windows 8 does then i might upgrade
then i open WMP 11 and start playing some music. After listening to that i heard some weird sound lag, I believe its called crackling. I searched on internet found some solutions, but none worked and none was for mine sound card.This wasn't happening on Win XP. Oh and if i have older version of driver it works way batter (only hear crackling when my cpu goes up to 1000MB (100%) ), but then my Microphone goes really quiet like I disabled microphone boost.Hope you understand my problem.

My wife HP Pavilion DV6175ea laptop running windows 7 ultimate 32 bits was fine with the sound until a month ago. Note that upgraded from vista since the windows 7 launch. From that date till now it as no sound from the speakers but it is ok from the headphones. Tried different audio drivers but no results. Tried to insert and remove headphonde jack several times with no results.
