Question Latency issues causing audio clipping

Feb 12, 2020
I have been searching what's going on a lot and I can not figure it out.

My stats from latencyMon

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. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. 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 0:09:30 (h🇲🇲ss) on all processors.

Computer name: DESKTOP-K9MQD2B
OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64)
CPU: GenuineIntel Intel(R) Core(TM) i5-7600K CPU @ 3.80GHz
Logical processors: 4
Processor groups: 1
RAM: 8132 MB total

Reported CPU speed: 3792 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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): 5413,30
Average measured interrupt to process latency (µs): 3,581183

Highest measured interrupt to DPC latency (µs): 3280,50
Average measured interrupt to DPC latency (µs): 1,596356

Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 3395,858122
Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0,117243

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): 5346,849156
Driver with highest DPC routine execution time: rspLLL64.sys - Resplendence Latency Monitoring and Auxiliary Kernel Library, Resplendence Software Projects Sp.

DPC count (execution time >=4000 µs): 0

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.
