System interrupts, Latency, HDaudbus.sys

Hi there! This solution seems to have worked for many of you guys, but I just tried it (updated the specified key in the registry from 0 to 1), restarted and the problem is still here - crackling in the audio. I have a Lenovo Legion 5 Pro with Windows 11. Any further help would be much appreciated!

To fix this, you need to switch "High Definition Audio Controller (Microsoft)" to MSI mode. In the registry in the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI""YOUR HD AUDIO PARENT""\DeviceParameters\Interrupt Management\MessageSignaled\InterruptProperties\ "MSISupported" Change to "0x00000001"
YOUR HD AUDIO PARENT see in Device Manager\Sound, Video and game controllers\hdaudio, realtek and other\Properties\Details\Parent

This fix worked for me so far with HDAudBus.sys. However, I changed it to MSI Mode vide MSI Mode Utility v3.1. Yet, the latency is still high for this driver at 56 compared to the rest of my system (not including other latency spikes from the drivers mentioned near the end of this comment. That being said, there's a few other drivers causing the same issues. Wdf01000.sys is extremely high at 242.1. When it's not this driver it's a Direct X driver dxgkrnl.sys or another Nvidia driver. nvlddmkm.sys. Any idea how to resolve these as well since they are all related? Wdf01000.sys has extrememly high ISRs at nearly 600,000 with roughly the same amount of DPCs. HDAudBus.sys has 52,000 ISRs with 54,000 DPCs. dxgkrnl.sys has 0 ISRs and 22,000 DPCs. Nothing else on my system is causing ISRs or DPCs.
 
Hello! First of all thank you for the solutions, it all worked super well at first. After changing the MSI from 0 to 1 the crackling stopped... However, just yesterday I got a Windows 11 update and the crackling is back. The MSI setting is still at 1, I've tripple checked, I have no idea what the updates did... This is so frustrating, I'm using and external audio interface (Steinberg UR44) and just a couple of days ago I was able to get a stable ableton live session... I just had to switch on plane mode, restart, and music was go... now I do the same and it's impossible to run, it crackles and interrupts audio... the audio driver itselfs says it's an USB interruption... but it's the same message that I got when I changed MSI from 0 to 1... after the change the message never appeared again...

This is very frustrating, I don't know if it is due to windows udpating, but that's the only change in the computer from a completely working Ableton session to an impossible nightmare I'm faced with right now... :(
Does anybody have a similar problem or has found any permanent solution?

Ok! This is rather bafling, but unplugging the Ethernet cable seems to have helped... If somebody smart knows why that would be the case and if that could have been the problem in the first place... It'd be fun to know why though...
 
This is what I did to fix the crackling audio (I also had some freezes when I clicked on the volume symbol in the taskbar, it would freeze for a second, and then back to normal) on my Legion 5:

0 - Create a Restore Point first, or something.
1 - Open Device Manager
2 - Go to Sound, video and game controllers
3 - Disable everything but Realtek Audio, or what you are using as output.

My POV:
*Sound, video and game controllers*
Nahimic Easy Surround device - Disabled
Nahimic mirroring device - Disabled
NVIDIA High Definition Audio - Disabled
NVIDIA Virtual Audio Device (Wave Extensible) (WDM) - Disabled
Realtek(R) Audio - Didn't touch

4 - Update the driver that is left, Realtek(R) Audio.
5 - Choose: "Browse my computer for drivers / Locate and install a driver manually."
6 - Choose: "Let me pick from a list of available drivers on my computer"
7 - In my case I got the following list of drivers:

High Definition Audio Device
Realtek High Definition Audio Version: 6.0.9088.1 [22/12/2020]
Realtek High Definition Audio Version: 6.0.9363.1 [07/06/2022]

8 - Only installed the "what I assume" is the base one: "High Definition Audio Device", the first one on the list.
9 - It will ask to restart. When I did the crackling was gone. Till now...

Follow on your own risk.

Went to watch a video where I heard the crackling problem and know it's gone.
The freezes aren't happening but with this problem I will need more time to see if it happens again.

Goodluck!
