Hi to Dave_B
As you can see I have the same Motherboard as you and I have the same 15 minute peak as you, LatencyMon tells me it is Ntoskrnl.exe.
I have managed to lower it from the 1000’s (40000) at it’s highest to under 600.
All my other readings are now below 140.
The Things I have done successfully to lower latency.

Disable Core Parking in the registry
HOW TO DISABLE CPU CORE PARKING IN WINDOWS 11.
Open the registry editor.
Navigate to:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings
Right click the PowerSettings folder and search for dec35c318583.
Double click ValueMax and change the value to 0.
Restart the computer. -
I use a very old firewire interface and Set it’s IRQ priority to 1.
You could probably do the same with a USB interface.
Open msinfo32.exe and go to “System Summary\Hardware Resources\IRQs”
Find the IRQ for your audio interface.
Next, open the Registry Editor, (regedit.exe) and navigate to HKEY_LOCAL_MACHINE\SYSTEM CurrentControlSet\Control\PriorityControl.
Create a new DWORD value in this key, and call it IRQ#Priority, where # is the IRQ of the device you wish to prioritize
In my case it was IRQ 17Priority
Double-click the new value, and enter a number for its priority. Enter 1 for top priority, 2 for second, and so on.
Close everything reboot and it’s done.
- Use PowerSettingsExplorer app
Under Processor untick these two boxes 1) Processor idle demote threshold 2) Processor idle promote threshold ------ restart.
Then go to power settings in Control Panel ---- Set to high performance then under “change plan settings” then under “change advanced power settings”
Make sure 1) USB suspend is disabled 2) wifi suspend is disabled (max performance) 3) GPU set to maximum performance.
Then under Processor Power Management you will find two new settings, Processor idle Promote and Demote Threshhold. Set both to 100.
Then Restart.
The biggest difference came from disabling Core Parking.
Please back up registry before starting.
I also did what was in the video you posted and found that if I set it at 3000 I got best results, any higher than this and other readings got worse.
But as with you none of these stop the 15minute peak caused by Ntoskrnl.exe, there must be a way surely – it is just so annoying.
At least with it being below 600 I can make music.
