CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 0:00:30 (h:mm:ss) on all processors.

Computer name: DESKTOP-4LJ7B8U
OS version: Windows 10 , 10.0, version 1903, build: 18362 (x64)
Hardware: G3 3579, Dell Inc., 03TF0Y
CPU: GenuineIntel Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
Logical processors: 12
Processor groups: 1
RAM: 16243 MB total


_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2208 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): 1246.90
Average measured interrupt to process latency (µs): 4.954838

Highest measured interrupt to DPC latency (µs): 1201.0
Average measured interrupt to DPC latency (µs): 2.224474


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
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): 266.134964
Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total ISR routine time (%): 0.037869
Driver with highest ISR total time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Total time spent in ISRs (%) 0.040033

ISR count (execution time <250 µs): 1837
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-999 µs): 1
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): 1888.673913
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total DPC routine time (%): 0.07530
Driver with highest DPC total execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Total time spent in DPCs (%) 0.171703

DPC count (execution time <250 µs): 110887
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-999 µs): 816
DPC count (execution time 1000-1999 µs): 2
DPC count (execution time 2000-3999 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: latmon.exe

Total number of hard pagefaults 56
Hard pagefault count of hardest hit process: 31
Number of processes hit: 4

Hi Shesh Narain Tewari. 🖖

Try to update windows to the latest version.
There's an urgent bios update for your laptop: version 1.11.0 (6 gen 2020); check your laptop downloads in dell support for your laptop (and read CAREFULLY their instructions).
These two updates/upgrades could hopefully solve your problem.
 
hey guys,
the problem is still not resolved. Please Help.
