Hi to everyone, i had a problem with my laptop, detected this after the sound began to buzzle and freeze while executing working programs such as Android Studio and others (sometimes this happens during meetings).
Struggling with this for more than 2 months, if no additional programs run the sound is perfect, and when Windows launching the greeting sound is always freezing too(in that case disabling quick boot helps).
What i have already tried:
- updated drivers
- rollbacked drivers
- updated bios
- rollbacked bios
- update windows
- Restored Windows to factory settings
- changing power settings to max productivity
- in clean boot the issue is not disappeared
- in cmd
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
DISM /Online /Cleanup-Image /CleanHealth
- something else but I do not remember
wdf01000,
nvlddmkm
dxgrln
ACPI
ntoskrkln
some of them always with very high DPC, depending on what program I use and some other conditions that I do not know, sometimes launching the same program shows different drivers with high DPC but in half of the cases it is wdf01000
P.S. u can write your suggestions advice and questions in English or Ukrainian or Russian. Thanks
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.

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): 182839,10
Average measured interrupt to process latency (µs): 16,999999
Highest measured interrupt to DPC latency (µs): 182835,50
Average measured interrupt to DPC latency (µs): 11,000308

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.

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: msmpeng.exe
Total number of hard pagefaults 539
Hard pagefault count of hardest hit process: 201
Number of processes hit: 22
