Hi

I have ran Latency Mon as I am getting issues when using using my Traktor Kontrol s3 DJ controller causing real time audio play back issues and the above driver is reporting Highest execution of over 5.83 which appears to be causing the audio issues - have you any advice on what I can do to improve this?

Windows/drivers/BIOS are all up to date

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.

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): 418.20

Average measured interrupt to process latency (µs): 18.544421

Highest measured interrupt to DPC latency (µs): 399.30

Average measured interrupt to DPC latency (µs): 5.148406

_________________________________________________________________________________________________________

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): 72.415941

Driver with highest ISR routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total ISR routine time (%): 0.008239

Driver with highest ISR total time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in ISRs (%) 0.008239

ISR count (execution time <250 µs): 68316

ISR count (execution time 250-500 µs): 0

ISR count (execution time 1000-2000 µs): 0

ISR count (execution time 2000-4000 µs): 0

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): 5830.930749

Driver with highest DPC routine execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Highest reported total DPC routine time (%): 0.116586

DPC count (execution time >=4000 µs): 1

_________________________________________________________________________________________________________

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 49848

Hard pagefault count of hardest hit process: 23033

Number of processes hit: 76

    Hi, I solved my problem. (HP victus 15, Windows11)

    I got this message from 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. Also one or more ISR 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.

    I did followed steps and still had the problem.

    1. windows update
    2. checking driver updates from hp(There was no recent update)

    But finally, I solved problem by:

    1. Installing nvidia gaming graphic driver
    2. Changing default GPU from 'auto select' to 'high performance nvidia processor' in nvidia control panel(3D option and PhysX)

    I'm not English native so be aware of translation.

    Not solved, but reduced...

    Hello!

    So many years I have same problem on Windows 10 (22H2) with Behringer UMC202HD USB 2.0 (every driver since 5.00, now it have 5.57).

    The overall audio dropouts when I playing Naraka Bladepoint. The sound dropouts for 1 second every 1-2 minute.

    Behringer driver 4.59 worked fine, but Behringer support doesn't see the reason in their drivers.

    There is no any problem with onboard Realtek HD Audio and Creative X-Fi Titanium PCIe.

    Chiming in to say that, after months of searching for a solution, this suggested NVidia settings tweak mentioned above was *finally* the fix for me as well: Nvidia Control Panel -> Manage 3D Settings, and setting Low Latency Mode to "Ultra", and Power Management Mode to "Prefer Maximum Performance".
