_________________________________________________________________________________________________________ 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 1:35:15 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: LAPTOP-G46LM8RA OS version: Windows 10 , 10.0, build: 17763 (x64) Hardware: OMEN by HP Laptop, HP, 8257 CPU: GenuineIntel Intel(R) Core(TM) i5-6300HQ CPU @ 2.30GHz Logical processors: 4 Processor groups: 1 RAM: 8081 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed: 2304 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): 4190,20 Average measured interrupt to process latency (µs): 6,153036 Highest measured interrupt to DPC latency (µs): 1785,60 Average measured interrupt to DPC latency (µs): 2,004611 _________________________________________________________________________________________________________ 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): 576,391493 Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation Highest reported total ISR routine time (%): 0,026097 Driver with highest ISR total time: Wdf01000.sys - Aparat wykonawczy struktury sterowników trybu j¹dra, Microsoft Corporation Total time spent in ISRs (%) 0,045467 ISR count (execution time <250 µs): 1751883 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 27 ISR count (execution time 1000-1999 µs): 0 ISR count (execution time 2000-3999 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.

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.
