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 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  0:00:16  (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   3696 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):   2071.828562
Average measured interrupt to process latency (µs):   3.431079

Highest measured interrupt to DPC latency (µs):       2040.244120
Average measured interrupt to DPC latency (µs):       1.789729


_________________________________________________________________________________________________________
 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):              36.138528
Driver with highest ISR routine execution time:       dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Highest reported total ISR routine time (%):          0.000456
Driver with highest ISR total time:                   dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation

Total time spent in ISRs (%)                          0.000503

ISR count (execution time <250 µs):                   151
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 >=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):              44.946429
Driver with highest DPC routine execution time:       Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total DPC routine time (%):          0.000228
Driver with highest DPC total execution time:         Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in DPCs (%)                          0.000678

_________________________________________________________________________________________________________
 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:                 msmpeng.exe

Total number of hard pagefaults                       1
Hard pagefault count of hardest hit process:          1
Number of processes hit:                              1

Maybe try removing your overclock and running at stock settings, and then trying the test again?

Unstable OC can cause all kinds of problems.

It should be noted that the issue didn't occur with HBO GO so as I assumed for months, it's not hardware related. It happens on youtube and a few other sites which I can't name off the top of my head.

I'm not familiar with LatencyMon so forgive me, is the issue exclusive to one browser? Is general windows related sounds in sync? Not that there's many but have you noticed issues there?

It's not exclusive to a browser sadly, both Firefox, Edge, and Chrome exhibit the issue.

I'm sure you've already tried this but have you update audio drivers? Through Realtek or something similar?

Yes, I've tried that with multiple drivers, oddly like I said, the issue is site specific. I don't think the issue persists on Twitch.tv but I can't truthfully recall. I do know it certainly doesn't affect HBO GO or VLC app

It could be an issue with engine that those websites use to play video, you know how everything used to use Flash? I think Twitch uses HTML5 player now? Maybe your system doesn't like HTML5 player?

Definitely seems plausible, I don't know what's the cause or fix though. I've heard disabling hardware acceleration but that's not a compromise I'm willing to make. At the very best, it's a workaround rather than a solution. The issue obviously isn't the system's hardware.
