First off: I'm sorry if this is the wrong sub forum but i've found similiar threads in it so i put it here!

Hello! For a few days now i have a problems that feels like it's getting worse. I've been using this exact same setup for a few years now with the only addition of a brand new SSD and HDD 2 weeks ago. That mean i also made a clean fresh windows 10 install at the same time and my old HDD is not even plugged in anymore. At first a restart fixed the sound stuttering, then the problem vanished after leaving the PC one for some time and now it's always there.


The Problem: I experience a lot of heavy sound suttering on my PC, nevermind if i'm just in teamspeak talking to people or playing games, the problem is always there.


What i've tried: I've been on google for a long time now and tried soooo many things, i've found some threads with a similiar problem in this and other forums. I have now finally narrowed down the problem with LatencyMon but there are so many things that could be the culprit now that i'm lost. I have absolutely no idea what to do. I've tried disabling and enabling many different audio and nvidia drivers, i've tried reinstalling them, older versions, tried different sound qualities, i made sure my performance settings are on high with the minimum and maximum CPU speed on 100% and nothing. Nothing fixed it. The latency is higher or lower sometimes but that changes just when restarting my pc so i can't give any infos on that. GPU up to date, multiple clean installations. All the other drivers are up to date aswell. I even installed the realtek audio driver to see if that makes a difference but it only made my microphone quality way worse.


7 Minutes LatencyMon report with only google chrome open:

edit: Several hours later for some reason this is how the ISR count is looking now: https://i.imgur.com/Kseasei.png


While clean installing my GPU drivers i have had LatencyMon open. At the point of the installation when it uninstalled my old GPU drivers the ISR count from dxgkrnl.sys immidiatly stopped rising and a few second later the ISR count from HDAudBus.sys aswell. Only the USBPORT.SYS, ataport.sys and stoport.sys kept climbing slowly. The installation is now finished and my dxgkrnl.sys started rising again but the HDAudBus.sys still stopped.


A video how the stuttering sounds: YouTube For some reason the sound isn't in sync with the video but for the sake of the problem it's sufficient. IT USUALLY ISNT AS EXTREME AS IN THE VIDEO, but it's there constantly with stuttering every second.


My PC Specs:


Operating System: Windows 10 Pro 64-bit (10.0, Build 17134)
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: GA-890GPA-UD3H
BIOS: Award Modular BIOS v6.00PG
Processor: AMD Phenom(tm) II X6 1090T Processor (6 CPUs), ~3.2GHz
Memory: 8192MB RAM
Page file: 4656MB used, 9688MB available
DirectX Version: DirectX 12


Since i can't really do anything with my PC at the moment because this is seriously annoying i will probably refresh this thread every few minutes and will be able to answer all the question you guys have should you decide to help me :)


Greetings,

[FONT=&quot]Okay i'm back. I've now tested the ubuntu on a usb stick and i didn't have any problems there, also restarted a couple of times and watched some youtube videos on it and i didn't hear a single stutter. Now back on my windows 10, at this point a clean install might fix it for a few days/weeks but from what i've found in many threads on the internet it will probably come back if not fixed proberly. It also appears to be a Nvidia driver problem since the ISR stopped going up instantly as soon as i made a clean install on my GPU driver and the installation was at the part where it deinstalled the old driver. I sadly don't have any other usb audio device to test.

Hi Geronimo2033,

Please install and run Speccy, give it 20 seconds or so to fully populate the report fields, use the File menu to Publish Snapshot, and then add the report link it generates to your next reply. It's probably the most efficient way to give us potentially important details about your system.

We could try capturing a trace using the built-in Windows 10 wpr command. You'd start it, let it run in the background using the system as you normally would until the glitch happened, and then stop wpr to save the trace to a file.

To do so, open a command prompt with administrator privileges (the title bar of the command console should show Administrator: Command Prompt). Then run the command:
Code: 
wpr -start GeneralProfile

Leave the command window open while you use the computer and when the glitch happens switch back to the command window and run:
Code: 
wpr -stop d:\general.etl

We'd then need to try and analyze the general.etl file so you'd need to make it available. They can get rather large so you'd want to zip the file and make the zip file available via a cloud drive or file sharing service if you'd like us to look at it.
 
Hello cwsink! Before we go into this further: I just installed a clean copy of windows 10 on my SSD, i made sure to fully remove the old windows. I wanted to be thorough with what i do and test if anything i did along the way maybe triggered it but for some reason, i can't even imagine to think of how that is possible, the problem is still there. Stuttering all the time.

Here is my public snapshot: http://speccy.piriform.com/results/CWaibmBFSxY7p0zZ2tTV73L
Here is the general profile you requested: File-Upload.net - generalgeronimo2033.zip
 
I downloaded the etl and I'll have a look. Glancing at the speccy report, it looks like you're using the FB BIOS for your motherboard and I'm guessing your motherboard is a revision 2.0 unit. Do you know if that is so? I ask because there are newer BIOS updates available and it looks like one addresses an audio issue for something... I'm not quite sure what. Anyway, that's something we may need to look into updating but let me see what the etl tells me (if anything.)
 
I bought the PC as it is from ebay so i'm not in possesion of any packages from the parts of my pc so i don't how i can detemine if my botherboard is rev 2.0 or 3.0. I also don't really know how i would begin updating my BIOS since as far as i know it doesn't have UEFI. I'm not sure if that's the reason tho, i've been using that motherboard for quite some time now.
 
The revision number on Gigabyte boards is usually found on the corner marked by the red box in the attached picture.

I'm seeing a very busy storahci driver. Please make sure all of the SATA cables are firmly attached to the motherboard and drives. Please also manually run Windows Update and make sure any and all availalbe updates are installed if you haven't done so already. I'll look further but in the meantime please address the above.
 
I wouldn't bother with drivers from the support page. We may update the BIOS but please hold off for now.
 
I will feel incredible stupid if after all this time the culprit is me not beeing able to proberly plug in stuff :D I will do that, walk the dog and will report back in about half an hour!
 
Update, now that my pc is back on for about 30 mins the latency is spiking up just as high as before it's not even close as frequent anymore, i can barely feel and hear anymore stutter but there are still some occasional clicking sounds. dxgkrnl.sys and HDAudBus.sys now have abour the same ISR count which is still extremely high.
 
Were you running LatencyMon while doing the wpr trace? It installed a driver that I'm guessing it uses to sample what it monitors but it's adding its own DPCs regularly which aren't necessary for the etl traces. They aren't a huge addition but it might be enough to push the total time enough to cause glitches. After stopping or uninstalling LatencyMon and rebooting please create a new etl trace and make it available. The DPC graph looks better already, though.
 
Did that trace have any audio glitches? It looks quite clean from what I can tell.
