Windows 10: Audio Stuttering and Pc Freezing Randomly

This issue is driving me insane for a while I've dealt with it but I really would like to get rid of it if possible. Sometimes when I'm using my computer it will randomly have what I like to call micro freezes/stutters where the mouse freezes, the audio stutters and gets choppy and the game I'm playing lags like it would if you had high ping. I ran latencymon and saw that something obviously wasn't right but I don't know what to do. I've done some things to try to fix this issue and they include

Sfc /scannow

Dism

Uninstall/reinstall audio drivers

Clean boot

Disk Defrag


The specs of my rig are

Processor-IntelR CoreTM i7-9700F CPU @ 3.00GHz, 3000 Mhz, 8 Cores, 8 Logical Processors

Graphics Card-NVIDIA GeForce RTX 2070 SUPER

Ram-16Gb

Motherboard-Gigabyte Technology B365M DS3H WIFI

OS-Windows 10 Build 1904

Here is the stats from the latencymon, if anyone knows what will help please let me know, its driving me insane, my theory is that it has something to do with the wireless driver but I don't know what I could do. Thank you


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 0:05:58 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: 54654.40

Average measured interrupt to process latency µs: 46.696861



Highest measured interrupt to DPC latency µs: 54587.60

Average measured interrupt to DPC latency µs: 43.986990





_________________________________________________________________________________________________________

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: 552.386667

Driver with highest ISR routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, Microsoft Corporation



Highest reported total ISR routine time %: 0.009247

Driver with highest ISR total time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation



Total time spent in ISRs % 0.013585



ISR count execution time <250 µs: 69475

ISR count execution time 250-500 µs: 0

ISR count execution time 500-1000 µs: 4

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: 50330.070

Driver with highest DPC routine execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation



Highest reported total DPC routine time %: 0.015880

Driver with highest DPC total execution time: ntoskrnl.exe - NT Kernel & System, Microsoft Corporation



Total time spent in DPCs % 0.042711



DPC count execution time <250 µs: 254878

DPC count execution time 250-500 µs: 0

DPC count execution time 500-10000 µs: 30

DPC count execution time 1000-2000 µs: 0

DPC count execution time 2000-4000 µs: 0

DPC count execution time >=4000 µs: 25





_________________________________________________________________________________________________________

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: svchost.exe



Total number of hard pagefaults 2267

Hard pagefault count of hardest hit process: 911

Number of processes hit: 19

Windows 10 freezes randomly

I had already tried turning off fast startup, to no avail.
Will look at the list you provided, thanks. Hard to do when computer freezes on the Windows loading screen though. *Biggrin

I had tried that as well... no result.

 

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

 

Random audio stuttering and mouse freezing


"High Definition Audio" suggests you only have the generic, basic function, Windows installed sound driver rather than the correct sound hardware driver. If this is the case, install the correct sound driver as step 1.
