Audio buzzing/pop
HiI have had a problem for a long time. Every once in a while when I listen to music or watch video, the sound is buzzing / pop. I updated the drivers, the bios, I performed a clean installation but nothing has changed. How can I solve it? I did a test with latency mon and this is the result:
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. 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 0:06:01 (h:mm:ss) on all processors.

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): 100360,30 Average measured interrupt to process latency (µs): 10,384257 Highest measured interrupt to DPC latency (µs): 100333,50 Average measured interrupt to DPC latency (µs): 4,431526 _________________________________________________________________________________________________________ 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): 2878,897796 Driver with highest ISR routine execution time: Wdf01000.sys - Runtime framework driver modalità kernel, Microsoft Corporation Highest reported total ISR routine time (%): 0,024353 Driver with highest ISR total time: Wdf01000.sys - Runtime framework driver modalità kernel, Microsoft Corporation Total time spent in ISRs (%) 0,024763 ISR count (execution time <250 µs): 42670 ISR count (execution time 250-500 µs): 0 ISR count (execution time 500-999 µs): 1 ISR count (execution time 1000-1999 µs): 1 ISR count (execution time 2000-3999 µs): 2 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. Highest DPC routine execution time (µs): 100370,170341 Driver with highest DPC routine execution time: ndis.sys - NDIS (Network Driver Interface Specification), Microsoft Corporation Highest reported total DPC routine time (%): 0,141570 Driver with highest DPC total execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation Total time spent in DPCs (%) 0,498228 DPC count (execution time <250 µs): 594039 DPC count (execution time 250-500 µs): 0 DPC count (execution time 500-999 µs): 4571 DPC count (execution time 1000-1999 µs): 74 DPC count (execution time 2000-3999 µs): 8 DPC count (execution time >=4000 µs): 0 _________________________________________________________________________________________________________ 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.
