Drivers/Hardware :: Sound Stuttering And High Latency
Sep 16, 2015
I've been having an issue with my sound were it starts stuttering after some time for no reason. I've downloaded LatencyMon and it showed me that wdf01000.sys goes over 50ms after a couple of hours while ACPI.sys can go higher than 1ms. They both got high DPC with wdf driver going off the scale.
So obviously the culprit is wdf01000 driver. I wanted to know if there is a way to found out which program or hardware uses this driver? Using trial and error method i've found out that it is probably a software program called LCDHost which displays temperatures, weather, loads and other settings on my g19s keyboard LCD screen but its kinda hard to believe that it would cause this issue.
Also i couldn't find out what ACPI.sys does besides being related to power management or bios. I've got a warning number 15 in my windows event log saying that BIOS is trying to access EC embedded controller and an error 56 related to "Application Popup" which mentions ACPI. I don't think that ACPI.sys is causing any issues but it is the second highest latency culprit.

At first everything seemed fine. Everything was working, I only needed to upgrade the VGA driver. I have a xonar D1 card with uni-xonar which worked immediately.
Than when I listened to music I noticed clicking and stuttering which got really horrible after while.
Talked about it on hydrogenaudio: Clicking, stuttering after upgrade to Windows 10 - Hydrogenaudio Forums
I clean installed VGA, updated the LAN driver, re-installed xonar. Things improved but they still suck. Clicking is still a regular occurrence.
I checked latency when LAN and the soundcard was disabled but latency still sucked:
Since I was using the very same hardware for years without these issues and I have doubts that several hardware or their drivers suddenly started misbehaving I'm guessing it might be an issue in win10 itself.
I attached the latest measurements. (screenshots and report) The worst values still belong to the same as the first time: VGA, soundcard, LAN, USB, ntoskernel

GPU: EVGA GeForce GTX 980 Ti
CPU: Intel Core i7-3820 Sandy Bridge-E Quad-Core 3.6GHz

My problem I believe is Windows 10, I've googled like no other but I can't seem to fix the issue. I set my PC up for easy wipes, because of this I did clean installs of 10 then to 7 and then back to 10. Windows 7 did not give me this issue.So onto the issue: I get weird popping sounds in my headset and what I can only describe as momentary episodes of extremely rapid stuttering, there is FPS drops that I can see sometimes, not sure if it's the stutter or par to the issue. Sometimes I can open up a game like League or Warframe and not have any issues. Sometimes the issue will pop up mid-game, late-game, or simply just randomly. I can be watching youtube at my desktop and it will start. Sometimes it starts with Windows.Just to be clear, the sound issue is on W10, I didn't have this issue on 7. I am nearly 100% sure it's not the headphones as they sound absolutely glorious in 7 and sometimes with 10 (when the issue isn't happening).Some issues that I don't really think are related but I've noticed since the upgrades:
- On W7 I had some start-up issues, happened 2 or 3 times, didn't stick long enough with 7 to find out.
- In some games, the resolution is messed up in that I've got a box that my mouse cannot pass that is smaller than my resolution (resolution is set to 4k). I can see the entire game, but my mouse can only go so far. This is fixed by restarting the program (sometimes).
- Watching Twitch in full screen drops FPS.
- Something that makes me wonder if W10 hates 4k resolution is that VERY often programs like TeamSpeak and Steam don't stick to where I place them.
They'll be reset in random locations throughout my desktop.I think it has something to do with Creative. I've heard a lot of talk about how great their tech is and how poor their software is.

I've built a new PC (i5 6600k, GTX 970, 16 GB DDR4 RAM) that's cost me a lot of money only for it to have to have loads of sound cracking whilst gaming.
I've already had someone else on another forum have a go at fixing this but they couldn't get to the root of the problem. They believed the problem was something to do with my storage subsystem.
Anyway, I've done the usual recommendations. Updated Bios, disabled my network drivers, uninstalled realtek audio and disabling CPU states and all thing related in bios.

Every time I reboot it seems I lose my audio on my sound blaster x-fi titanium pci express sound card. Also; it seems like every time I turn my audio controller off for awhile then back on; i get at high pitched hum sound and then when i try and play something I get crackling audio. What the heck is up with windows 10 and these issues? Ive never had these problems with my sound card under windows 7.

Today, I upgraded my Toshiba Laptop to Windows 10, it was previously windows 8 but the computer was windows 7 default. My sound was working fine until I installed Windows 10..I upgraded to Win10 and I played a youtube video and I hear choppy glitchy like sounds few once in a while.. How do I stop it from chopping out? My brother has the same computer as me and he upgraded, his doesn't make the choppy sound. I tried with his headphones in my computer, it still occurred. How do I stop it from chopping out?

I've got a really weird problem with my sound on my PC. Whenever i try to listen to anything on my computer using headphones, i can hear the music/background noise perfectly clear, but when the volume is High, sound stop for 2/3seconds, and couple of seconds sound - and again. Headphones are new and I do not use Realtek.

I have a Fangbook III made by Cyperpower PC. I am unable to play sound via the on-board speakers for the laptop. I am however able to play sound through the 3.5mm auxiliary jack input. I have speakers set as default device under the playback settings.
This is where is gets strange. Whenever I attempt to delete the Realtek audio driver, whether it is through windows or a 3rd-party driver uninstallation software, Realtek always comes back within a few seconds. Right before it does come back, under playback, it separates speakers and headphones with both having the driver High Definition Audio Device. If I hurry before the Realtek driver comes back the speakers seems to work! But once the Realtek audio speakers comes back, the default speakers and headphones goes away and I continue to have the same problem with the Realtek driver.
I attempted to reformat the computer with windows 10 and erase all drivers but Realtek was already installed. I assume it is required for this specific laptop? How to direct the Reaktek High Definition Audio driver to use the speakers instead of the auxiliary jack?

my computer will always randomly freeze for 1-3 seconds when I do normal tasks (like using chrome and skype). The freezes cause audio and mouse to also freeze during that time.
I tried to swap CPUs, get a new mobo, use different RAM and nothing works. I've got this problem since Windows 8. But its been progressively worse. Now I also sometimes have problems POSTing and the display will turn black when I boot up to the login screen.
I used latencymon to check which drivers are causing the problem and when I disable my GPU drivers the stuttering is gone. I don't have any of these problems when using DirectX apps. My GTX 660 has the latest drivers installed.

The Conexant HD Audio Sound Driver was replace by High Definition Audio Device after i update to Windows 10 Home Version 1511 from 1011
Now if i want to plug my earphones to the left side of the computer where the audio jack socket is located the sound does not transfer to my earphones except i will change the default sound device from speakers to headphones.
How can i set it to automatically when i plugin my headphones/earphones/external speaker automatically transfer the sound to this device without changing the settings?

I just bought this sound card and installed drivers for Windows 10. (and a crapton of bloatware with UI of Win XP media player...)
Everything works well except one thing: when I change the sound (or mute) I don't see Windows 10 volume bar. I mean these:
The sound itself changes, but there is no indicator. Is there a way to fix that?

I have been having some high CPU temperatures on my laptop while I have just been using MS Word. While this has been happening, I have been looking at the temperatures in HWmonitor, on average it was reading 110 degrees Celsius.
So I put the laptop into hibernation and and let it cool down to room temperature, when I turned it back on the temperature was reading 85 degrees Celsius. I think that there may be a problem with the temperature sensor, but when Touch the area where the heat is coming out of, it still feels very hot when I am only word processing (HW monitor says 110 degrees celsius).

Macbook pro early 2011 bootcamp was not willing to let the SSD run in AHCI mode in windows 10, so I did EFI installation of windows 10. Everything seems to work but the audio card.
Code: This device cannot start. (Code 10) in the High definition audio controller.
I tried installing the drivers manually and automatically and from the bootcamp but this error persists.
Is the problem in the EFI implementation of the macbook pro early 2011 that windows cannot read , or is it related to drivers ? I downloaded latest videocard Intel HD 3000, and realtek generic driver. The audio drivers seems to be from currus logic.
On Bootcamp install (BIOS) the sound card works fine, but in EFI it can not start the driver.

i had my HP Pavilion dv6 7050ca laptop for 3 years now and it was working perfectly until today...I put in my battery (I usually only run my laptop with power cable without battery) and unplugged it to go downstairs to work. After I was done, i put it to sleep, brought it back upstairs and replugged in everything (headset, mouse) including the power cable and once I woke up the laptop, it became insanely stuttery, from the windows 10 interface to the mouse cursor to games to web browsing to everything! Everything still opens fast but it is just the movement of things: mouse cursor, gaming, web browsing, videos, etc. I already tried shutting down and taking out the battery and running it with only power cable like I used to, reinstalling graphics drivers, restarting the computer, unplugging nd re plugging, nothing seems to be working!

This started happening the same day I upgraded from 8.1, but it went away. Suddenly it's come back worse than it ever was. I've tried uninstalling my Realtek drivers and rebooting and I've tried changing the sample rate. No change. I can't listen to music, watch videos, play games without the audio stuttering.

Im using firefox on windows 10. I had choppy video when I first bought this computer a month or so ago and installed windows 10. I changed the webmedia thingy to false to stop html5 and that fixed the problem for quite awhile till this morning. I had been watching netflix on the computer the day before (for the first time) Now today I have the choppy video back. Also noticed the non full screen view appears different. The resolution seemed smaller. The non full screen was smaller and now appears bigger. Resolution is still set right as far as I can tell.
Now I get the choppy video on you tube only and only if using firefox. I also noticed my add on for opening in foreground tab had been disabled. I did not disable it. I re enabled it. I would like to continue to use firefox and windows 10 but fear I may have to go back to 8 or just use internet explorer. About all I use the computer for is watching videos and mostly on youtube. Now I have a worthless to me computer. If I go down to 144p it works fine but anything higher gives me problems. I also have no way of doing a system restore. Only offers me an option for windows 7 even though I am running 10. says there are no restore points even though I set up my computer to save restore points.

After i upgraded to win10 i've encountered a problem i can't seem to figure out what is causing it. This happens on youtube in firefox, on twitch in opera and in vlc playing local files (all apps are latest version). But it's not a constant issue, it's intermittent. So it might happen every 10 min or so where something seems to hog all resources for a second.
What i've tried.
Completely uninstalled and reinstalled vlc.
Dism /Online /Cleanup-Image /Restorehealth
sfc /scannow
All completed successfully, but with no change.

My Desktop computer has been having issues with games constantly stuttering and occasionally crashing for what seems like no reason. There are error logs reported on Event Viewer for the crashes but no information that I can see related to the stuttering.
I can only describe this stuttering as a sudden drop of FPS to 0 with sound glitches and then back up in a second or 2 working fine. Other instances of this happening can also be a drop of FPS to around 20 with sound glitching out much more and for a longer period of time. The sound glitching I refer to sounds like a something being constantly repeated over itself so for example instead of "Hi" it would sound like "Hihihihihihihihihihihi". It may also be worth mentioning that I have a external sound card installed on my system, a SoundBlaster Zx.
The crashes I refer to happen instantaneously and I have not been able to explain them whatsoever. In the event viewer I have noticed with games Fallout 4 and CS:GO they appear with the application error event 1000. fallout 4 refers themselves as the faulting module and CS:GO refers to a Nvidia process called "Nvd3dum.dll" (See Screens Below)
Since these issues has shown up I have replaced my PSU and my RAM to see if that would change anything. The specific PSU and RAM I got is a Corsair RM850 and a 16GB set (2X8GB) of Crucial Ballistix Sport. These changes have done nothing to alleviate the issues I have been experiencing. I have also attempted to unplug all HDDs and SSDs as well as reseat all components of my Desktop. I have reinstalled windows 10 multiple times using a USB flash drive. I have attempted Reinstalling GPU Drivers (Nvidia) and tweaking Graphics settings using the NVIDIA control panel. None of my attempts to fix have worked thus far.
Most of the fixes I have tried are related to the error 0xc0000005, which appears in the event previously mentioned above, but I am not the most savvy when it comes to more in depth analysis and repairs.

Sound comes through perfectly fine on my laptop's built-in speakers. However, when plugging my headphones into the 3.5mm headset jack, there is no sound whatsoever. The system recognizes that my headset is plugged in. In fact, the microphone on my headset functions perfectly when plugged in, but the headphones themselves are outputting no sound.
I tested the headphones on other computers and devices, and they work. In Device Manager, the device is listed as "Realtek High Definition Audio". However, the only sound device listed in Control Panel is "DTS Audio Control Panel".
I've tried uninstalling the audio device from Device Manager, and then reinstalling the driver from Realtek's website. However, this is met with the exact same results... no sound through the headphones, and "DTS Audio Manager" is installed in the Control Panel instead of Realtek HD Audio Manager.
If I navigate to Control Panel -> Sound -> Playback, "Headphones" is not listed as a device. Instead, Speakers/Headphones is listen as the sole device. Also, I ran DirectX Diagnostic Tool, and it returned absolutely no errors.
