Hi, i've spent the last months looking for a solution to this problem. Basically i get a lot of annoying audio pops and cracks whenever there's something playing on my computer. I've run dpc latency checker and LatencyMon and they display a latency of 1100 us. Ive also run the windows performance analyzer, i'll leave the results of everything at the end. I tried upgrading every driver and bios. I tried disconnecting every usb device. I tried changing options in the bios(the only one that made a slight difference was disabling c-state but it only reduced the latency of 100 ue, without removing the pops). There seems to be a lot other people suffering from this problem on the web, and on this website also but i didnt managed to find a solution that worked for me. I would prefer not to re install windows (also for a lot of people this seems to not be a solution). If there is something else i need to provide in order to get to the bottom of this problem feel free to ask me.

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): 533,172676
Average measured interrupt to process latency (µs): 5,157127

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
