I did the test but I can’t analyze it…unfortunately
CONCLUSION
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. 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 0:03:12 (h:mm:ss) on all processors.

SYSTEM INFORMATION
OS version: Windows 10 , 10.0, build: 18363 (x64)
Hardware: Precision 7540, Dell Inc., 0T2FXT
CPU: GenuineIntel Intel(R) Core™ i7-9850H CPU @ 2.60GHz
Logical processors: 12
Processor groups: 1
RAM: 32522 MB total
\
CPU SPEED
Reported CPU speed: 2592 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.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
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): 15070,50
Average measured interrupt to process latency (µs): 16,178741
Highest measured interrupt to DPC latency (µs): 15059,10
Average measured interrupt to DPC latency (µs): 6,159348

Highest reported total ISR routine time (%): 0,007272
Driver with highest ISR total time: ACPI.sys - Sterownik ACPI dla systemu NT, Microsoft Corporation
Total time spent in ISRs (%) 0,011779
ISR count (execution time <250 µs): 7032
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 0
ISR count (execution time 1000-1999 µs): 0
ISR count (execution time 2000-3999 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): 15017,692130
Driver with highest DPC routine execution time: dddriver64Dcsa.sys - Dell Diags Universal Device Driver, Dell Inc.

DPC count (execution time <250 µs): 125707
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 1087
DPC count (execution time 1000-1999 µs): 27
DPC count (execution time 2000-3999 µs): 11
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: svchost.exe
Total number of hard pagefaults 122
Hard pagefault count of hardest hit process: 41
Number of processes hit: 15
