[SOLVED] PC Audio and Video Stutter

[KeelerMcNugget]

So I've seen a few threads that appear to be having the same issue such as this one which is explaining my issue exactly: https://forums.tomshardware.com/threads/solved-pc-audio-and-video-stuttering-issues.3452273/. This began roughly one week ago with my video and audio losing sync while I watch any streaming service, but I could refresh the page and fix it for around 15 minutes before I had to do another refresh. Just a few days ago, the issue escalated to stuttering. When I turn on or restart my computer, the issue isn't there but gradually gets worse . As long as there is no audio or video, my computer will run fine. When I am only playing music on spotify though, I have no issues unless I am running something else with video and audio. Video games become unplayable after 30 minutes to an hour of playing from constant audio stuttering and sounding robotic, and video stuttering with frame drops at the same time; they are definitely correlating. I recently factory reset my computer, with the first thing installed being the antivirus, Bitdefender, so it is highly unlikely that it is caused by malware or viruses. In the thread I posted above, the user said they were able to fix their system by removing their pci adapter driver and using an ethernet cable instead. I don't feel this is likely in my case though because I am already using an ethernet cable, and when disabling my wireless adapter, nothing changed. I did have Driver Easy installed but don't think I actually installed any drivers through it but rolled back recent installs anyway to be safe, and reinstalled drivers through Alienware's SupportAssist program. Additionally, I also completely uninstalled and reinstalled the driver for my NVIDIA GeForce RTX 2070 SUPER, so that shouldn't be the issue either. To check for hardware damage, I used both SupportAssist and Hardware Diagnostics through BIOS. I have not noticed any issues through task manager either, with my CPU only running a max of 40% and GPU reaching a high of 79 degrees celcius while playing. I'd be inclined to say it is a software issue, but I am just about lost at this point. Any help at all would be much appreciated, and I am happy to try any suggestions or answer any questions. Thank you, and I apologize for the length of this.

If it is helpful at all, here's some info on my computer:
Alienware Aurora R11
Intel(R) Core(TM) i7-10700F CPU @ 2.90GHz 2.90 GHz
16 GB RAM
NVIDIA GeForce RTX 2070 SUPER

audio/video sttuters issue is mostly cause by incorrect bios settings or weird driver installed or some 3d party app/service running

so lets start with reseting bios settings either by clearing CMOS or loading bios default values from within BIOS
run pc with that (no bios change pls)
then see if it got resolved
if not, do a clean boot
https://www.manageengine.com/patch-...How-to-perform-Clean-Boot-in-Windows-8-and-10
if it doesnt help, run latencymon
https://www.resplendence.com/latencymon
run it in background, it should tell something

Hello, I haven't responded because the stuttering appeared to be resolved, and it was for a while but it has popped up again.

Another forum I seeked for help on suggested resetting network settings, which did appear to work.

I am pretty sure I did reset my bios settings. I also did a clean boot as well, and am still doing it.

Running latencymon states the following:
-I do not have a WLAN adapter
-I set power management to high instead of balanced through settings (didn't see it in BIOS)
-I have tried looking at BIOS updates and DPC routines, but am still confused on what I need to do exactly or what they mean

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 0:24:48 (h🇲🇲ss) on all processors.

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): 34395.30
Average measured interrupt to process latency (µs): 5.415135

Highest measured interrupt to DPC latency (µs): 34376.70
Average measured interrupt to DPC latency (µs): 2.901506

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.

_
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: bdservicehost.exe

Total number of hard pagefaults 1197
Hard pagefault count of hardest hit process: 576
Number of processes hit: 19

Sorry for the length of this, but I may as well show all information. Thanks.

 

[kerberos_20]

u can use BB codes [ code], but nvm
latencymon reports ndis.sys which is microsoft kernel drive that runs network, if you dont have WIFI, then lan network remains
uninstall your current network drivers, then download new driver from your network card manufacturer (intel maybe?)
