I have recently bough a Traktor S4 Mk2 DJ controller and noticed some issue with random popping in my audio playback. I am using a HP ENVY - 13ad010nd as my portable traktor laptop. I have already ruled out the speakers or headset as the culprit as I notice no issues when the Dj controler is connected to my desktop computer. So from what I could gather this seems to be one of two issues: (1) My hardware being out of date or defective (2) The drivers on my laptop interfering with audio latency.
I came to this conclusion after following the windows tuning guide available from the native instruments site. I have attached some screenshots from the LatencyMon diagnostic.
If anyone has anymore knowledge on this problem or a fix that worked for them I would love to know.
Further conclusion fron 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. Also one or more ISR 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 0:22:20 (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): 10845,90
Average measured interrupt to process latency (µs): 7,573529
Highest measured interrupt to DPC latency (µs): 10826,10
Average measured interrupt to DPC latency (µs): 1,813702

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: msmpeng.exe
Total number of hard pagefaults 174324
Hard pagefault count of hardest hit process: 50293
Number of processes hit: 101
