Ironsounds :
Hello... It is known that some MB's have higher Latency and Spikes than others... you do have a high end "special" intel MB, but I have No actual Data/experience with. The Audio has to be processed by the CPU with either card/chip (software device)... can you post a image of your data you collected so far?
4b) have you tried 24 bit/44khz or 24 bit/48khz with both devices?
6) do you have "core parking" disabled? win10 setting available? utube it.
7) Have you tried the OS setting to background services? Control Panel\All Control Panel Items\System\advanced system settings/advanced/performance settings/advanced-adjust for performance of background services.
8) Here is info that get passed around in the cakewalk forum http://www.blackviper.com/service-configurations/black-vipers-windows-10-service-configurations/
9) Go into all your Communication and OS APPS... under preferences Disable any Auto update/file searches and never.
So after a lot of testing and almost 2 days without having the trouble, I have come to the conclusion that the conflicting driver is USBPORT.SYS still haven't found a solution.
Heres the latencymon stats:

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 0:03:09 (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): 2066.044910
Average measured interrupt to process latency (µs): 4.199061
Highest measured interrupt to DPC latency (µs): 2062.500418
Average measured interrupt to DPC latency (µs): 1.079381

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.

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: chrome.exe
Total number of hard pagefaults 296
Hard pagefault count of hardest hit process: 142
Highest hard pagefault resolution time (µs): 69481.554231
Total time spent in hard pagefaults (%): 0.041433
Number of processes hit: 6
