Question Audio crackling and major FPS drop ?

Audio Crackling and FPS Drops.

A few days ago my headphones started crackling. I figured that they were just getting old. The issue continued to get worse, until it made gaming impossible due to performance issues. Here is my LatencyMon results.

Highest ISR routine execution time (µs): 120.760
Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%): 0.002760
Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Total time spent in ISRs (%) 0.003772

ISR count (execution time <250 µs): 48484
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 0
ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0

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.

Highest DPC routine execution time (µs): 1668.880
Driver with highest DPC routine execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 527.56 , NVIDIA Corporation

Highest reported total DPC routine time (%): 0.063454
Driver with highest DPC total execution time: nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 527.56 , NVIDIA Corporation

Total time spent in DPCs (%) 0.186277

DPC count (execution time <250 µs): 477176
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 459
DPC count (execution time 1000-2000 µs): 7
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 0

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: msedge.exe

Total number of hard pagefaults 23260
Hard pagefault count of hardest hit process: 4428
Number of processes hit: 60
