_________________________________________________________________________________________________________ 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 0:30:18 (h:mm:ss) on all processors. _________________________________________________________________________________________________________ SYSTEM INFORMATION _________________________________________________________________________________________________________ Computer name: DELL-INSPIRON-5 OS version: Windows 10, 10.0, version 2009, build: 19044 (x64) Hardware: Inspiron 5567, Dell Inc. BIOS: 1.5.0 CPU: GenuineIntel Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz Logical processors: 4 Processor groups: 1 Processor group size: 4 RAM: 16282 MB total _________________________________________________________________________________________________________ CPU SPEED _________________________________________________________________________________________________________ Reported CPU speed (WMI): 270 MHz Reported CPU speed (registry): 2712 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. _________________________________________________________________________________________________________ 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): 3932,30 Average measured interrupt to process latency (µs): 22,928162 Highest measured interrupt to DPC latency (µs): 3861,40 Average measured interrupt to DPC latency (µs): 6,672666 _________________________________________________________________________________________________________ REPORTED ISRs _________________________________________________________________________________________________________ Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

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 412 Hard pagefault count of hardest hit process: 107 Number of processes hit: 24 _________________________________________________________________________________________________________ PER CPU DATA _________________________________________________________________________________________________________ CPU 0 Interrupt cycle time (s): 31,158931 CPU 0 ISR highest execution time (µs): 287,113201 CPU 0 ISR total execution time (s): 0,539782 CPU 0 ISR count: 4342 CPU 0 DPC highest execution time (µs): 3954,720133 CPU 0 DPC total execution time (s): 9,624364 CPU 0 DPC count: 654432 _________________________________________________________________________________________________________ CPU 1 Interrupt cycle time (s): 12,574556 CPU 1 ISR highest execution time (µs): 28,172566 CPU 1 ISR total execution time (s): 0,000221 CPU 1 ISR count: 20 CPU 1 DPC highest execution time (µs): 712,172566 CPU 1 DPC total execution time (s): 0,965935 CPU 1 DPC count: 35366 _________________________________________________________________________________________________________ CPU 2 Interrupt cycle time (s): 12,894698 CPU 2 ISR highest execution time (µs): 0,0 CPU 2 ISR total execution time (s): 0,0 CPU 2 ISR count: 0 CPU 2 DPC highest execution time (µs): 1766,1250 CPU 2 DPC total execution time (s): 0,894501 CPU 2 DPC count: 56552 _________________________________________________________________________________________________________ CPU 3 Interrupt cycle time (s): 12,260526 CPU 3 ISR highest execution time (µs): 0,0 CPU 3 ISR total execution time (s): 0,0 CPU 3 ISR count: 0 CPU 3 DPC highest execution time (µs): 894,917404 CPU 3 DPC total execution time (s): 0,469539 CPU 3 DPC count: 25542 _________________________________________________________________________________________________________
