I have audio popping. All drivers and BIOS are latest.

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. At least one detected problem appears to be network related. In case you are using a WLAN
adapter, try disabling it to get better results. 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 0:01:00 (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): 2407,30
Average measured interrupt to process latency (µs): 14,744584
Highest measured interrupt to DPC latency (µs): 2364,80
Average measured interrupt to DPC latency (µs): 4,004081

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.
Process with highest pagefault count: none
Total number of hard pagefaults 0
Hard pagefault count of hardest hit process: 0
Number of processes hit: 0
