XPS 8950, wdf01000.sys causing severe latency
I have been dealing with severe latency issues (probably with Wdf01000.sys) on this rather new Dell computer.
Somebody help me or I want to return this computer. I have been dealing with this for months. It is killing my business.
latencymon reports the following:
_________________________________________________________________________________________________________
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.
LatencyMon has been analyzing your system for 0:15:42 (h:mm:ss) on all processors.

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): 4431.70
Average measured interrupt to process latency (µs): 5.277287
Highest measured interrupt to DPC latency (µs): 1092.80
Average measured interrupt to DPC latency (µs): 1.73730
_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

_________________________________________________________________________________________________________
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: svchost.exe
Total number of hard pagefaults 6766
Hard pagefault count of hardest hit process: 1734
Number of processes hit: 55

I believe you are correct about doing a poor job in assigning priorities.

Waves should be listed on the Windows Add/Remove screen in Win 11. Good idea to manually set a System Restore point before uninstalling Waves. Or, you can use Revo Uninstaller (free) to uninstall Waves. It can create the System Restore point for you. It will also scan your PC for any "leftovers" after the uninstall is done, and you should also delete those. (Never delete anything that appears in red on the Revo "leftover" screens.)
You'll have to reconfigure Waves after you reinstall it. First, make sure Waves is set to load at every boot. Then power PC off normally from Windows and disconnect all audio outputs (eg, speakers, headsets). Power on and after you get to desktop, plug in front left/right speakers.
Waves should pop up and ask what you connected (may take several seconds to appear). Select best option from list. Then plug in rear left/right speakers, if any, and see if Waves pops up again. Plug in subwoofer, if any, last and see if Waves pops up. Then open the Waves control panel ("W" icon on taskbar) and click the big Playback box. Make sure Output Device correctly recognizes your config.Try to change it there, if necessary.
You can also enable the Equalizer on that same configure and select type of music, and change bass settings etc. Save the profile with a new name (not Waves default name). You can create multiple profiles with different names for different types of audio. Last one used is loaded at next boot, but you can change that by opening the Waves control and selecting a different one.
Note: Waves doesn't apply if you're using (NVidia) audio over HDMI to speakers, or if you've installed an add-in audio card. In this case, make sure NVidia (or sound card) is selected on Windows Sound screen instead of Realtek Audio, and make sure Waves doesn't load at boot.

Ron, can you clarify this:
Note: Waves doesn't apply if you're using (NVidia) audio over HDMI to speakers, or if you've installed an add-in audio card. In this case, make sure NVidia (or sound card) is selected on Windows Sound screen instead of Realtek Audio, and make sure Waves doesn't load at boot.
I am using DELL XPS8950 and Focus Rite 2i2

@mywebguytaylor - Not familiar with Focus Rite 2i2.
Is it compatible with Realtek Audio?
Do you have to change the Windows Sound Output device setting to something other than Realtek?
Are speakers directly connected to Focus Rite 2i2 or to the Audio Out ports on the PC?
If Waves is loading at every boot, have you tried disabling Waves?
Do you have latest drive installed for Focus Rite 2i2, if any?
Maybe you need to contact their tech support for assistance...

Hello,
I know this thread is old, but I’ve been looking for an answer to my latency problem for months now and I had to join in.
In March 2023, I bought a Dell Inspiron 3910, 12th Gen Intel Core i5-12400 running at 2.50 GHz with 16GB or RAM. This new PC is replacing my old Dell T1500 (around 12 years old) running a i7-870 CPU.
I’m doing audio recording (Focusrite Scarlett 18i20) and quickly noticed some pops/crackles, etc. This is when I started looking for the problem. LatencyMon, BIOS tweak, Power management, etc., etc., etc.
After many tests, the only thing that gave me the best results was to delete the Dell bloatware. Unbelievable.
I have been using audio DAW for almost two decades now and it’s the first time I’m experiencing this kind of problem. I just can’t believe that I have to make any adjustments to the CPU (which in my case is probably 100x more performant than what I used to work with over the years for doing music stuff) or whatever else for that matter. I just can’t believe it.
Even if my system is somewhat “ok” now, I’m still experiencing crackles when doing almost nothing. I’ll just say that my confidence is greatly affected towards Dell products and that I can no longer make music with pleasure, being always worried that the system will generate some glitches at some point.
I just found this interesting explanation on Youtube (July 2023) that the 12th, 13th and 14th gen Intel CPU are different in the way that the interrupt chips “IOH, Input Output Hub” is not implemented in the same way and cause more DPC latency. https://www.youtube.com/watch?v=6dNuR16gJ2A (Just viewing this video, I had audio glitches).
I cannot explain anything of this, I'm just curious to know if this has anything to do with the problems I, and many other people out there are experiencing.
Anyone here good enough to help me understand what this is about?
BradHof: I won’t be buying any Dell computer neither (this is my third one).
Rohe : I'm sorry, I cant agree when you say that I paid Dell for the hardware and Microsoft for the software. I bought a computer from Dell. Dell installed Windows in it and is responsible for that choice. Your argument is like saying, your microwave oven does not work because of the firmware in the controller that was programmed by XYZ so we are not responsible for this. I will never accept this.
