I am having this strange sound lag/stutter/pop and sometimes FPS drop while playing games and videos from youtube in chrome/firefox.
I scanned with latencyMon and it shows DPC latency issues with some buffer thing sometimes while at other times it shows CPU throttling and network issue.
I isolated the network(Unplugged the LAN cable and disabled network adapter) and the issue was still there so it can't be network issue.
Its not related to my speakers since it happens with in ear 3.5 mm sony headphones too.
My PC is 8700k, 1070ti GTX, 32 GB RAM(I replaced RAM recently and issue is present with both old and new RAMs).
Temperatures usually fluctuate around 65 Degree Celcius for CPU with average 40% load and 60 degree celciuos for GPU.
HwInfo tool shows no thermal throttling in CPU and I disabled C states in Bios. I even tried turning off idle mode for CPU in windows so it constantly used 100% CPU and the issue was still there for the audio stutter/pop.
I give up now. I have reinstalled network drivers, nvidia drivers audio drivers and what not.
It seems to happen all of a sudden and than after restart it goes away for a while.
I have a corsair RM 850x PSU and I am sure its working fine. I have removed GPU and cleaned any dust from components and reinstalled everything except CPU and HDDs.
This issue started happening after I got M.2 SSD installed last month maybe it is related(I don't know). The games on this SSD works fine though.
I once moved TEMP directory paths to this new SSD, but than I reverted to original windows TEMP directory.
Below is the latest report from LatencyMon.

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 0:07:05 (h:mm:ss) on all processors.

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): 4242.10
Average measured interrupt to process latency (µs): 3.434262
Highest measured interrupt to DPC latency (µs): 4239.50

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: mrt.exe
Total number of hard pagefaults 5126
Hard pagefault count of hardest hit process: 2335
Number of processes hit: 129
