Windows 10: Loud popping sound from time to time (Latencymon report included)

Hi,


Some sound issues have been stressing me out.


I just solved the "Windows Audio Device Graph Isolation" error by disabling startups, at least for now.

But there's another one, the loud popping/clicking sound that occurs every few minutes.

I followed some guides online, ran Latencymon and got a report.


Now I don't know what to do with the information.


What I did so far was disabling sound enhancements and reinstalling audio driver.

Power throttling is disabled.


Here's a screenshot: https://prnt.sc/ojxv6m


The detailed report:

_________________________________________________________________________________________________________

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 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 2:18:50 (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): 34834.90

Average measured interrupt to process latency (µs): 8.851877



Highest measured interrupt to DPC latency (µs): 34619.20

Average measured interrupt to DPC latency (µs): 2.438135

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): 671.108302

Driver with highest DPC routine execution time: storport.sys - Microsoft Storage Port Driver, Microsoft Corporation



Highest reported total DPC routine time (%): 0.002576

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.



Process with highest pagefault count: msmpeng.exe



Total number of hard pagefaults 38354

Hard pagefault count of hardest hit process: 19864

Number of processes hit: 79

delivery report pops out several times

Hy friends,

From last 2 days, from time to time, after I send a sms the delivery report keeps pop out, pop out for many several times. I dont know why. I have made a virus scan and no virus has been detected.

I dont know why the delivery report keeps pop out even if I sent the message for 4 ours.

Is very weird.

Which can be the problem???



P.S. the phone does not send messages auto, but the delivery report keeps popping out for many times for the same sms.

 

every time adjust volume, I hear windows sysem sound, annoying loud


Sorry, I don't know of any way to do that as I've never heard anything like that. How are you adjusting the volume? And do you experience the same thing if playing a mp3 file or when a video is not playing, for example?

How are you playing it? From a file? On line?

If there were such a sound it would be listed here:

Check your DPC latency with something like LatencyMon

Press play and let it monitor for a few minutes, if the bars with the highest interrupt to process latency , dps and isr routines goes to red switch to Drivers tab, sort by Total Execution Time and see what you have there. The drivers with the highest execution time can be responsible for your sound popping issue.
