Windows 10: Audio stuttering Help

Good day,


I have a problem with my PC lately. There has been some audio stuttering that has been driving me crazy. I am not very savvy with technology so I do not know the cause of this or how to fix it.

Upon searching the internet, I came across this program called LatencyMon that apparently detects the cause of the stuttering. Unfortunately, I do not understand anything about it and I do not know what to do to fix my problem.


Here is the copy of the text in 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. 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 0:00:19 (h:mm:ss) on all processors.

SYSTEM INFORMATION

_________________________________________________________________________________________________________

Computer name: JOEL-PC

OS version: Windows 10 , 10.0, build: 17763 (x64)

Hardware: 80SM, LENOVO, Toronto 5A2

CPU: GenuineIntel Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz

Logical processors: 4

Processor groups: 1

RAM: 8097 MB total

CPU SPEED

_________________________________________________________________________________________________________

Reported CPU speed: 240 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): 100747.20

Average measured interrupt to process latency (µs): 8.121185



Highest measured interrupt to DPC latency (µs): 100686.80

Average measured interrupt to DPC latency (µs): 3.470433





_________________________________________________________________________________________________________

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): 55.236667

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



Highest reported total ISR routine time (%): 0.003923

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



Total time spent in ISRs (%) 0.003923



ISR count (execution time <250 µs): 572

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

ISR count (execution time 500-999 µs): 0

ISR count (execution time 1000-1999 µs): 0

ISR count (execution time 2000-3999 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): 100912.688333

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



Highest reported total DPC routine time (%): 1.185801

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



Total time spent in DPCs (%) 1.483709



DPC count (execution time <250 µs): 40820

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

DPC count (execution time 500-999 µs): 20

DPC count (execution time 1000-1999 µs): 0

DPC count (execution time 2000-3999 µs): 0

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: chrome.exe



Total number of hard pagefaults 4

Hard pagefault count of hardest hit process: 2

Number of processes hit: 3

Audio driver conflict causing stuttering?

Hi Techhelper89,

Unfortunately, I did the instructions as mentioned in the thread and the stuttering persists. I used the link provided: and the steps requested

http://www.tweaking.com/files/setups/tweaking.com_windows_repair_aio_setup.exe

I also tried reinstalling the Realtek Audio drivers as suggested by the thread to no avail.

I've also added some links of how the stuttering looks and sounds like to the main post of this thread. I hope it helps identify the issue.

One more thing I noticed after the above steps is that I can boot with Nvidia HD Audio drivers disabled but the stuttering persist. Enabling then disabling "cures" the stuttering for a while. Although, when this is happening while the Nvidia Audio drivers are
disabled (as there is an enable option) the icon doesn't look like one that is normally disabled (with a small circular arrow down icon).

Cheers,

Ben

Hi marcosdipaolo,

I find an article: [Solved] Realtek Audio Stuttering After Upgrade to Windows 10 Does this can help you in some additions?
