Windows 10: Audio stuttering/faults and very high latency due to "ndis.sys"

Dear forum,


I am experiencing very high latency and audio stuttering when gaming or listening to music.

According to the diagnostic program LatencyMon it is because of "ndis.sys".

The stuttering is sometimes very bad (2-3 times in 30 secs), sometimes its much more frequent (when gaming for example), as in 2-3 audio stutters in 15 seconds.


You can see a screenshot attached. I have already tried cleaning the interior of my machine with a vacuum, reinstalling windows and changing the driver vor my network adapter. Nothing worked. Maybe it is good to know that my network adapter was not originally included in my machine. I bought it myself and installed it later on, yet this was last year and I've never experienced these problems before February. Until then, however, they keep coming and going. They were gone after my new installation of windows at the beginning of April but coming back now. I am using no virus defender apart from the native windows programs. Steam and Origin are running normally.


Can anyone help me out?


I've included a screenshot of my latencymon test and a file that I have made using Windows performance recorder. While "recording" my performance, I could identify two clearly distinctive audio problems.


I would be very grateful if someone could help me out, the problem is driving me nuts.


Thank you everyone!

High DPC latency causing audio stutters


Quite different hardware but this may have your attention.

Sound artifacts and high DPC latency seemingly related to storport driver can be caused by switching between Cx power saving processor states. My pci-express add-on soundcard works correctly only if C states greater than C1 are disabled:





If you want to give it a try, see your mobo manual:

 

Audio stuttering/buzzing and storport.sys high dpc latency

I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
I've already done to avoid repeated answers

I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

I would also like to know if having
Ricoh SD/MMC Host Controller and nothing else aside from that, under
IDE ATA/ATAPI controllers, is okay and won't cause problems?

please, I hope someone can help and answer this time around!

 

Sound stuttering and high latency from Wdf01000.sys and ACPI.sys






Unfortunately updating logitech software did not help.

So is there any way to find out which program or hardware uses that Wdf01000?
