    for the past couple of weeks i've been getting weird almost crackling noises on my laptop and i assumed the speakers were going until they persisted with headphones as well. Here's my LatencyMon

    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. 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 0:16:34 h:mm:ss on all processors.

    CPU SPEED

    _________________________________________________________________________________________________________

    Reported CPU speed: 2494 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: 20495.60

    Average measured interrupt to process latency µs: 7.813180



    Highest measured interrupt to DPC latency µs: 20470.80

    Average measured interrupt to DPC latency µs: 2.431609





    _________________________________________________________________________________________________________

    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: 313.953488

    Driver with highest ISR routine execution time: i8042prt.sys - i8042 Port Driver, Microsoft Corporation



    Highest reported total ISR routine time %: 0.001682

    _________________________________________________________________________________________________________

    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: 20820.840016

    Driver with highest DPC routine execution time: ndis.sys - Network Driver Interface Specification NDIS, Microsoft Corporation

    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 5380

    Hard pagefault count of hardest hit process: 721

    Number of processes hit: 110

  3. Audio stuttering/buzzing and storport.sys high dpc latency

    I've only had this audio issue for a few weeks already after I did a custom windows 10 install bc of a previous problem. I've also posted twice about this but no one has helped me yet. I'll post the following possible solutions and suggestions that
    I've already done to avoid repeated answers

    I did: audio troubleshooter, uninstalled then reinstalled audio drivers, disabled audio enhancements and tried different audio quality under the advanced tab.


    After more searching online I tried using DPC Latency Checker (and then LatencyMon to be more detailed) since I read that having high dpc latency can cause problems with real time audio among other things. Apparently
    storport.sys is the problem? I literally just have basic knowledge about anything regarding this kind of stuff and I don't have any clue on how to fix this so I just hope someone can help me and give me steps by steps suggestions on how I can solve this. my
    audio has just been driving me crazy with those stuttering sounds and I don't want it to worsen.

    I would also like to know if having
    Ricoh SD/MMC Host Controller
    and nothing else aside from that, under
    IDE ATA/ATAPI controllers
    , is okay and won't cause problems?

    please, I hope someone can help and answer this time around!

    Audio/DPC latency and performance issues

    DPC Latency while using LatencyMon

    which of the DPC Latency issues do you have? Video? Audio? Networking? or all 3? are you sure your using the term "DPC Latency" correctly? Examples of DPC Latency are when video or audio or networking has big slow downs for a second or two then back to normal, like video frame rate drops way down then comes back or audio cuts out momentarily and then back as normal or networking goes into a strange no down or uploading like it froze for a moment....Did you run a DPC Latency bench that said you have issues? Please tell us what is going on with your PC.
