Headset Drivers are causing latency issues, PLTGC.sys

Q: Headset Drivers are causing latency issues, PLTGC.sys

This is a problem that has been driving me up the wall lately with my headset. A few months back I bought a headset called Plantatronics Gamecom 780. I put up with the issues for awhile since I was in school and had no real problem with restarting the computer to get rid of the issues. But it always comes back and I can't seem to get rid of it.

LatencyMon seems to show that the driver that is causing this is PLTGC.sys which is the driver that comes with my headset, uninstalling the driver has no effect on it. I have no other visible ports to plug the headset into on the computer (2.0 USB Port in the front is busted), so I only have the ones that come with the motherboard in the back.

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.)

I have a recording studio.

What type of latency problem are you having? If it is a latency problem. In recording, PC sound cards have poor latency and are considered poor for recording.

Have you run the DPC Latency Checker? The Resplendence Latency Monitor tends to go overboard some times.

Hello everyone, Happy New Year!

I just installed my Christmas present to my self, an Audioquest Dragonfly ver 1.2

While it does sound better then the internal sound card I have pops going along with the sound. I researched the problem and found that i have rather severe latency issues, (please see screenshot).

I am looking for advice as the best way to solve this problem. I am also experiencing issues with the audio and video not being in sync no matter what i do and was wondering if this latency issue may be the cause of this also.

A:I need help with latency issues causing audio pops

Considering this is a USB connected device, I would look at the USB for issues, if you didn't have problems previously with the on-board audio.

Also, if you haven't done it, disable the on-board audio in the BIOS to avoid any conflicts.

Hello every one, since installing windows 7 professional i have been getting random spikes every now and then, when streaming from the internet like youtube, and its driving me insane. I've tried lots of things to try and solve the problem... But to no prevail! I will list below.

1. Turn off intell speed thing in bios (stops the cpu from going to sleep)
2. Turn off "allow the computer to put this device to sleep" on power management for lan card.
3. Turn off on board lan and use a seperate dedicated lan card (the card is not expensive only a 7 pound stlab n-210) and turn off let pc turn it off blah blah
4.disable HD5770 HD sound (in device manager i disabled it, but i dont think thats the problem)
5. Stop using morzilla firefox and tried using microsoft explorer (a latency monitor program advised me a extension in firefox was causing the spike)
6. Turn off onboard sound and use USB sound instead (i have both usb speakers and usb headphones)
7. Reinstall windows 7 pro and get all updates.
8. Uninstall mcafee and try browsing without it
9. Praying
10. Shouting at the computer.
11. updating every drive on computer, lan cards, graphics, windows update and so forth.
12. Updating bios (flash update) 1.7 latest for my mobo
13. read lots and lots of threads on many differnt leads to the cause, but finally i'm in belief its the lan, since unplugging the internet stop all the spikes and replugging it in causes instant spikes.

So, I installed Windows 7 RC today on my Dell Mini 10 and everything was smooth sailing.

At this point my only available resolution was 800x576.

Windows Updates picked up a couple of drivers, one being the Intel GMA 500 drivers. I installed the drivers and the system restarts.

The restart seems slow. I have about 45 seconds of a black screen and my cursor can be moved easily and then all of the sudden the login appears.

I login and the taskbar comes up, but the desktop is black. If I refresh the desktop my wallpaper returns and everything runs fine. The resolution at this point is 1024x576.

If I disable the driver I'm back to square one.

Anyone else experience this problem? Is there a better driver that I should be using? Any help or insight would be greatly appreciated.

I have an HP4100 printer that I am trying to use with a new Windows 7 laptop, and I have had a range of issues. Let me explain the saga in case any steps are important.

At first, it seemed simple. When I plug in the printer, Windows 7 searches for and finds an HP PCL6 driver that it installs. The problem is that this driver gives me PCL XL errors on some print jobs. I found all kinds of messages on HP message boards that the HP PCL6 drivers give these errors whenever anything is slightly amiss. So, it looks like that easy default will not work for me, anyway.
I discovered that there is also an HP4100 PS (postscript) driver available from Windows if I go to Windows Update. However, I cannot find any way to choose that driver instead of the default. I could not find any way to get Windows to stop automatically installing its preferred driver and ask me what to do. As an alternative, I tried going into Devices and Printers, right click the HP 4100 printer and select Printer Properties, to Advanced, then select New Driver. This gives me a chance to go to Windows Update for more driver choices, and then select HP4100 PS driver. It seemed to work. However, I immediately get an error that the HP 4100 PS driver is not installed. It appears that the PS driver is working. However, I get the driver not installed message every time I right click on the printer and select Printer Properties. Strange.

Looking for more options, I go back to HP to the only... Read more

A:audio drivers causing issues

I have a similar issue with a laptop that my church has used for several years as our music and video source. Suddenly there is noise and distortion in all audio sources, and even external sound devices have the same problem. VLC also starts to lag once the noise in the sound increases.

A deep analysis of hardware turns up a motherboard issue with audio sources that means the laptop is done being used for the purpose. We have acquired a new desktop system that is working 100% thus far. The laptop is now used exclusively for office and e-mail purposes only, replacing an aging desktop system that was starting to fail after 7 years of yeoman service.

A:Devices missing drivers... Updated, but still causing issues

Hi: The only issue I can definitely help you with is the driver for the pci serial port. You need this driver for that device. This package contains the Intel Management Engine Software version 11.0 for the supported Workstation models and operating systems. This package installs the latest Management Engine Interface (MEI) and Serial-Over-LAN (SOL) drivers, as well as Intel Management and Security Status (IMSS), to support Intel Active Management Technology (AMT) versions 8.x and 9.x. ftp://ftp.hp.com/pub/softpaq/sp74001-74500/sp74499.exe The multimedia video controller...do you have a tv tuner card installed? I do not think it is the graphics card. Please post the hardware ID for the multimedia video controller so I can figure out what it is. To find the hardware ID, go to the device manager and click on the multimedia video controller. Then click on the details tab at the top of the multimedia video controller window. Now you will see a Property drop down list, and it will be set to device description. Drop down on that list and select the 3rd item (Hardware ID's). Post the top string of characters that you see in the window. The SAS Controller issue, I would not be able to offer any suggestions for that.

I have the ASUS M2N-E SLI mobo. I'm using the built-in ethernet plug wired into my router. Lately what's been happening is when I turn on the computer the internet won't work. I have to right click the network icon in the system tray, click network and sharing center, click manage network connections, right click the one device listed (NVIDIA nForce 10/100/1000 Mbps Ethernet) and click properties. Then I click configure, drivers, update drivers, and I have to manually install one of the 2 drivers listed. One is from Mirosoft, and the other from nvidia. They are both named NVIDIA nForce Networking Controller. Either one works, I could install the microsoft one or the nvidia one and they'll both make the internet work, but as soon as I restart my computer it does the same thing again.

What I'd like to know is why it's doing this, and if there's a way to remove one or the other of the drivers from my computer. My idea is that it doesn't know which driver to use when the computer turns on so it doesn't use either one. If I can remove the microsoft one, I think it'd use the nvidia one.

Can someone PLEASE help me out, it's really becoming annoying. Thank you.

So I am pretty certain I'm having a PC side issue which is causing my pings to spike once per minute. I have talked with my isp and other technicians for long enough now to have eliminated all of the expected hardware / modem / isp network issues. They've changed the fittings on the modem/router (it's a combination one) and checked all the numbers, got the signal under control because it was getting overpowered at first, scanned for the wireless channel with the least noise and set the router to permanently use the channel as opposed to auto-scanning every minute (not that I could see this affecting the wired connection anyways).If I ping my router constantly (or any website, or run a tracert etc.) I will see a large spike in latency (up to 4000ms) once per 60 seconds, this only occurs when running my standard win7 boot from my SSD, if I run windows from another hard drive or from this SSD but in safe mode with networking the spikes do not occur at all. Other devices such as tablets and my phone do not experience the spikes on the same network.Network drivers are updated, I have run malwarebytes, ccleaner, adwcleaner, roguekiller, combofix and removed everything they found. I have tried disabling windows firewall (I re-enabled when it did not solve the issue), I have tried a couple of network tcp optimization tools. Nothing has solved the issue yet, I have already asked on various networking forums and no one can figure it out.I have tried closing all processes... Read more

Hi,

For the past few days I've been trying to fix the sound stuttering when I'm listening to music, and after monitoring the dpc latency it seems to be caused by a bad driver. I've updated all my drivers and tried finding which one is causing the latency spikes but no luck so far.

Also, I don't know if this means anything but when I open up hwinfo32 and the hardware summary is shown, i get this pattern:

When I close the summary it's back to normal. Does this mean it's related to one of the parts shown in the hwinfo32 summary?

My main computer just randomly started spiking constantly for no reason and now I can't even isolate what is causing the latency.

I am using Windows vista on my main computer that is directly connected to a DSL modem. Somehow this computer specifically causes my internet to spike really bad and really often, when I am playing games I would usually get a ping of 90 ms, I now get anywhere from 300-1500 consistently. I tested my other computers connection when this computer was not on the internet and it is completely fine but the second this one connects back to the internet, it goes back to being terrible. What makes it really weird is that the problem randomly started when I hadn't even changed or installed anything and it even persisted through a reformat of the computer.

Something that might be associated with the problem, around the same time this started happening I started getting a message says the Microsoft host process has been ended.

I set up a new system 2 months ago (mobo+cpu+ram+gpu). Fresh install of w8.1 with drivers from manufacturer install disk. I started getting huge lag spikes, which appear mostly when dragging windows around on the desktop or wiggling the cursor around. Basically the whole system just halts for 0,5-1 seconds. Also happens mkv playback, browsing etc, but most notably when moving the cursor.

I thought I messed up with the installation of windows so I reinstalled it again. No help there, so I started going through things that could be causing it, mainly bios settings, mobo drivers and various windows settings. Especially the management engine driver and HPET timer forcing/disabling. I thought I had it fixed for about 5 weeks, which it worked perfectly.

Couple weeks ago I upgraded my cpu. The system was 100% stable with 4,3ghz cpu overclock and some gpu overclock, IBT very hard passes, some tough memtests and 30 hours of Dying Light without any problems. Everything was fine until I needed to fix a non-related mobo network driver memory leak. Just a simple registry fix to stop network monitoring at system startup, but I also ran ccCleaner. After this the problems started again and its unbearable.

Mouse movement: I've used 3 mouses and the ones with high polling cause the worst problems. With 500hz/1000hz the interrupts become apparent eg. full second halts, but with 125hz settings its not that apparent. The latency is lower, but still there are problems, low fps in games for exam...

Hey guys, so I posted this topic a few weeks ago and told myself I'd just live with the issue - now I'm fed up...
 
Back story - explorer.exe is eating up a lot of my PC's resources. Basically taking up anywhere between 1-4.5gbs of ram as well as 10-100% of usage. I'm running Windows 7 Home Premium, i5, 64 bit, 6gb of ram. I've never had this issue in the past, but it appears to be an ongoing issue even after running numerous anti-malware/viral software. I've done a clean boot as well and that also did not fix the issue. I used Process Explorer to try and locate the issue, but had no success. And I also noticed that there are two explorer.exe process but both with different command lines.
 
Somewhat related: I play a lot of League of Legends and recently the ping has been well above 200 for me (usually like 80-100). So I opened up the resource monitor, and a lot of the latency is coming from the explorer.exe process. So when I kill the process, the lag goes away...or at least when I ping the server with Ping of Legends.exe. I'm not really sure what this means, but if it helps, then all the better.
 
Any suggestions would be extremely helpful. If you need more information, I will do my best to provide it. Thank you very much in advanced.

So I was at my wits end yesterday trying to troubleshoot this issue and when I read the guide it said the culprit will have the highest DPC count so I presumed it was the file at the top, turns out my problem is related to USBPORT.SYS. Now I'm beginning to verify all my drivers are up to date, which this is a fresh install of Windows so I also presumed all the drivers to be up to date. I disabled Windows from installing drivers but when I removed them and rebooted to begin the troubleshooting process, Windows had installed them without my permission. Any suggestions?

I know I have already solved this problem in the past, in task manager a process called "system interrupts" is displayed every time I move my mouse and it uses anywhere from 1% cpu all the way up to 80% cpu. System interrupts is also present when I'm not using my mouse and causes my videos and audio to stutter.

To fix this before I simply located the service in services.msc and disabled it thus system interrupts no longer operated under the DPC, but now I cannot locate the service associated with this process, I never wrote it down. Now I'd like to fix the problem rather than sweep the problem under the rug which I did by disabling a service. Any and all help will be greatly appreciated.

My problem is when I am watching flash videos, specifically YouTube and Twitch.TV, my sound stutters when opening another tab or just when simply watching the video and not doing anything else. Things like games and iTunes DO NOT stutter.

A good thing but sort of bad thing for troubleshooting is that the stuttering/popping of sound starts after a good 10 hours to a day of up time but DPC latency spikes are almost always there after a couple hours.

A:High DPC Latency, causing Audio STUTTERING after a couple hours uptime

If I'm correct, this only happens with Flash applications.

I assume you have only run DPC Latency Checker??? Have you run the Respledance Latency Monitor ? If not, suggest you run that as it may help you in troubleshooting.

Along with Sound drivers causing stuttering, Video drivers are also suspect, along with the Flash Player.

One other issue is the fact that Audio is on a Shared Interrupt (IRQ) with a higher priority device and in some circumstances the higher priority device can cause interruptions that sound like stuttering I haven't found how to manually change the Audio IRQ, but sometimes if the audio is uninstalled in the Device Manager (but do not uninstall the drivers) then the PC is restarted, when Windows starts it will detect and reinstall the sound. In some cases this will put sound on a different IRQ.

Recently I upgraded my Asus N550JK with a 512GB SSD, MX100 from Crucial, and replaced my DVD drive with the old hard drive. I successfully wiped the 1tb hard drive I had in before and installed Windows 8.1 64-bit onto the SSD. Almost everything is working
as intended.

When I opened task manager, I notice an odd thing, my cpu usage was higher when my computer was doing nothing at all. (seen here: http://i.imgur.com/bav1ACJ.png )

After doing some research I began using two tools to uncover the problem. The first of which, LatencyMon, told me that the ACPI.sys driver was causing issues. This is what I see:

I have also used the "Windows Performance Analyzer" developed my Microsoft, and found similar results:

http://i.imgur.com/E2xsz0L.png

I have updated my bios to version 208 and updated my chipset drivers to the latest version. I reinstalled the ATKAPCI package for the model N550JK and have had no luck.

I've contacted support many times and they cannot figure out what is wrong. I am slightly frustrated because my laptop only lasts for an hour on battery life due to this issue.

I can send you the .etl file if necessary, but I want to solve this issue. Research I've done indicates owners of computers with SSD's are more likely to have this issue, and it is surprisingly common in laptops.

Other people have suggested on various forums to rollback the bios to an earlier version... Read more

A:ACPI.sys driver causing large amount of DPC latency on Asus N550jk

Update and solution:

I've successfully fixed the problem.

On my HDD caddy, http://www.amazon.com/gp/product/B004Y8SGXW , there is a tiny switch on the side that when I switched it to the other position I no longer have any problem with ACPI.sys creating system interrupts. 

Another forum I was reading suggested that their HDD caddy had messy soldering so I took apart my caddy and only then did I realize that there was a switch. I tried to do some research on my caddy but couldn't find anything except in the reviews on Amazon,
where other people suggested flicking the switch if they were having any sorts of problems. Flicking the switch solved all of my problems.

From what I recall and a little searching I've been doing, it would appear that it could be caused by numerous drivers, although typically it's a network driver. I also came across an issue that was resolved by changing the AV software.

To rule out other software, you could likely perform a clean boot and then test latency.

I recently started playing WoW (on vista) since my computer is now way over the recommended requirements. The problem now is my connection. The first couple of days were fines with the latency at 150-200 ms which is good for a cable connection. In the past 2 days, however, the latency spikes and then overloads. I'll just be playing normally and the latency will spike up to 7000ms and will run poorly until it disconnects. Is there any idea on why this happens? I would like to get it fixed.

Recently been getting significant latency issues on my desktop after roughly a day/two of use (hibernating at night). This causes audio stuttering and static. Issue seems to be caused by ndis, and tcpip.

Using DPC Latency monitor I noticed it would skyrocket to red whenever the internet got a burst of use, for example refreshing a browser page, or receiving a message on skype. A la:
Spikes are page refreshes. Everything else is yellow (yellow not green as the software has issues with Win8).

Ran a LatencyMon scan with my network card disabled:
Quite the difference, stayed completely in the yellow in the DPC monitor.

Network card enabled:
Looks like tcpip and ndis are the offending drivers.

Been happening for a few weeks now. Restarting solves the problem but only for a day or two. All drivers are updated as far as I can tell.

Tried:
chkdsk r f
sfc scannow
dism scan/restore
defragment
disk cleanup
full virus scan
driver updates (as best as I can tell)
lots of other small solutions that escape memory

I have a mod that shows latency in real time when executing any ability in game, when the data center was 40 miles away latency stayed under 20(on the casting bar mod) at all times, now it spikes as high as 500(on the casting bar mod). Is this due to the long distance? My computer is much more powerful now too, so I dont know if this is an issue with AT&T or if its just something i have to deal with due to the long range of distance.

Hi there

I have been having some bizarre DPC latency issues with my system. I recently just did a clean install of the OS and updated all my drivers with a driver updater program (may have been where I went wrong here). I now have huge latency spikes according to LatencyMon and I was told to run xperf or something to find out which drivers were causing it.

the main problem drivers:

dxgkrnl.sys
cmudaxp.sys
nvlddmkm.sys
USBPORT.sys
tcpip.sys

system restore didn't seem to work. I have tried disabling drivers in device manager to no avail. I have disabled the network adapter, the USB controllers, the sound card, and my video card. Nothing has helped

I experience a fair amount of pops, buzzes and drops in sound. I don't know if computer performance for gaming is affected by this but it seems to be.

Please let me know what I can do here. Thank you for the help

I have major latency issues and from DPC checker have figured out that its my network adapters (or at least I think?). When I disable them, I get nearly perfect sound. Ive re installed them/downloaded new drivers multiple times and no difference.

I've disabled/enabled devices correctly in the BIOS.
I've tried various memory sticks, sound card devices, PSU's, network cards; non of which makes any difference.
I've 'run' memtest, and used extensive testing with post probe/micro-scope (micro 2000) which revealed no issues. I also dismantled it and gave it a thorough dusting and 'contact' clean, non of which has made any difference at all?
The problem goes away when the network is disabled. I don't want to have to disable the network connection every time I listen to music! All my drivers are up to date on windows 7. Also using pentium 4 CPU/DDR2 3Gb. All other functions work perfectly. The network card is a tenda W322p/PCI.
The same problem exists with either the motherboard on-board sound, or seperate sound card.
It sounds like a fast repetitive stutter similar to a vinyl LP styli that has got stuck in one groove over and over again; e.g. "gra-gra-gra-gra-grateful".

Been having some audio issue and I'm really close to giving up.

I re installed windows and in one of the past few stays I've started having audio crackling/static. Ended up with LatencyMon to see if it was driver related but the driver reports don't spike ( http://puu.sh/e39Fh/e43544115e.png ) unless I'm understanding this wrong. And I've disabled the cpu throttling for the most part. (I think)

It's very noticeable during a couple of songs, and it also happens when I quickly change between in-game menus (dota 2 for example, clicking on each of the menu tabs in quick succession causes a crackle)

Is this my onboard audio dying? I'm pretty sure I have the same drivers as my last windows install (although I'm somewhat confused about that, the gigabyte website states I have a VIA audio chip but their driver downloads only list RealTek Azalia stuff.

What can cause this aside from drivers and onboard audio hardware? Bad gpu drivers? Bad RAM?
edit: I just tried with some other peripherals and the crackling persists. Earbuds, different earphones and a USB headset. Tried in front and rear jack.

here's a pastebin with everything from latencymon audio issues / latencymon - Pastebin.com

A:LatencyMon measures high latency but doesn't appear to by drivers

For testing, uninstall the audio drivers and let Windows install the generic High Definition Audio drivers and see if that makes any difference.

To Uninstall the device and drivers, go to the Device Manager, Sound section. RIGHT click on the entry for the sound and then LEFT Click "Uninstall". ALSO, check the box to also uninstall the drivers. Restart the PC and when Windows starts it will detect and install the generic sound driver. See how this works.
