didnt seem to help me. still getting audio crashes and high dpc latency from tcpip.sys, dxgkrnl.sys and wdf01000.sys. cant figure out what is causing it.

Hi
I have ran Latency Mon as I am getting issues when using using my Traktor Kontrol s3 DJ controller causing real time audio play back issues and the above driver is reporting Highest execution of over 5.83 which appears to be causing the audio issues - have you any advice on what I can do to improve this?
Windows/drivers/BIOS are all up to date

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns
appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing
for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for
BIOS updates.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the
moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an
event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 418.20
Average measured interrupt to process latency (µs): 18.544421
Highest measured interrupt to DPC latency (µs): 399.30
Average measured interrupt to DPC latency (µs): 5.148406
_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.
Highest ISR routine execution time (µs): 72.415941
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation
Highest reported total ISR routine time (%): 0.008239

REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it
is interrupted until the DPC has finished execution.

DPC count (execution time >=4000 µs): 1

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped
file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and
blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream
resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 49848
Hard pagefault count of hardest hit process: 23033
Number of processes hit: 76

2024-03-20T10:50:43+00:00 #1 Find the audiosrv and audioendpointbuilder services (start taskman in admin mode, go to services tab, locate said services by description)
#2 Right click and "go to process"/"go to detail" (windows 10)
#3 Change the affinity (meaning what core the process runs on) to something other than cores 0 or 1 if you have a 4 or more core system.
It works because ACPI.sys and wdf01000.sys tend to run on cores 0 and 1. You put the audio stuff on cores 2 or 3 (etc.)
You leave your audio service free from interruption on other cores.Hi Daniel,
Thanks for the advice !
Since a few days I had latency problems with sound and graphics.
Thanks to LatencyMon I identified a problem with wdf1000.sys and applied your solution.
Since then, everything work fine ! :-) -

I'm running a Core i5 13600k, Gigabyte Z790 UD AC, 32GB DDR5, M.2 disk drive and keep getting random clicks during playback in my DAW (Cakewalk, latest version).
It drives me crazy and I'm getting tired to troubleshoot this issue that's being going on for the past year or so...
DanielNieto81, As soon as I right click on either audiosrv or audioendpointbuilder/"Go to detail" it brings me back to the Details tab and nothing is highlighted in order to pick a process to change it's affinity. How to know which process it's tied to?
Thanks
i might be super late to this reply, but when you look in task manager right before you right click and select go to details you will see a pid (process id number) for mine its 4400 and 5212. thats how you will know which to adjust affinity for. im testing this out now to see if it solves the issue for myself too.

2024-03-04T11:20:01+00:00 What finally fixed this for me (also using FocusRite) was to use the NVidia Game Driver, rather than the Studio driver...
No idea why the graphics driver was affecting the sound, but after trying every other fix and fiddle for latency issues, this was the thing that finally fixed it.
