Sound stuttering and high latency from Wdf01000.sys and ACPI.sys
I've been having an issue with my sound were it starts stuttering after some time for no reason. I've downloaded LatencyMon and it showed me that wdf01000.sys goes over 50ms after a couple of hours while ACPI.sys can go higher than 1ms. They both got high DPC with wdf driver going off the scale.
So obviously the culprit is wdf01000 driver. I wanted to know if there is a way to found out which program or hardware uses this driver? Using trial and error method i've found out that it is probably a software program called LCDHost which displays temperatures, weather, loads and other settings on my g19s keyboard LCD screen but its kinda hard to believe that it would cause this issue.
Also i couldn't find out what ACPI.sys does besides being related to power management or bios. I've got a warning number 15 in my windows event log saying that BIOS is trying to access EC embedded controller and an error 56 related to "Application Popup" which mentions ACPI. I don't think that ACPI.sys is causing any issues but it is the second highest latency culprit.
