[SOLVED] Experiencing High DPC Latency and Popping Sounds. FIX: I updated chipset drivers and bios.

ItsYaHomie04 · Apr 16, 2023

I've had this pc a while now. When I listen to music or watch videos on youtube or with the windows media player I don't hear any of the popping noices. When I do run games, that's when the popping occurs.
I noticed I had DPC problems by using LantecyMon, I heard a lot of people talking about it in other places.

The things I've tried so far:
-Choosing high performance in power settings (Control Panel)
-Checked for updates of every audio driver in the "Sound, video, and game controllers" section
-Disabled each audio enhancement for my default sound device
-Lowered sound format to lowest option available (16 bit, 44100hz (CD Quality))
-Defragged each drive

The computer specs:
CPU: AMD Ryzen 7 5800x 8-Core 3.8Ghz
GPU: MSI RTX 3060 Ti Gaming X Trio (or just NVIDIA GeForce RTX 3060ti)
Ram: 32gb (2x 16gb) DDR4 (not sure which freq(?))
m.2 ssd: Sabrent Rocket NVMe 4.0 (1000gb)
SATA ssd: Crucial 2.5 in. SSD (unsure of the actual name)
Motherboard: MSI MPG X570 Gaming Edge Wifi (MS-7C37)
PSU (don't know if this would matter in the current topic): Thermaltake Smart 700W

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. 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 0:06:38 (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): 1416.20
Average measured interrupt to process latency (µs): 13.259649

Highest measured interrupt to DPC latency (µs): 1410.30
Average measured interrupt to DPC latency (µs): 3.856369

_________________________________________________________________________________________________________
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 19023
Hard pagefault count of hardest hit process: 14712
Number of processes hit: 36

Hi!

Video STUTTERING, Audio CRACKS/POPS and dpc/isr LATENCY (posting instructions)

ItsYaHomie04 · Apr 22, 2023

Doing everything based off the thread xilolee shared with me..

The issue I have is that when I do any resource demanding task on windows (such as playing resource demanding games) my audio/pops a lot. Especially when I try to screen record with OBS.

The steps I've tried to fix this issue have been:
-Enabling high performance in the control panel's power settings
-Reinstalled and checked updates for drivers in the "Sound, video, and game controllers" section of device manager
-Disabled sound enhancements (those keep switching on for some reason)
-Disabling exclusive mode
-Lowered sound format to lowest setting possible
-Defragged each drive

Speccy link (if this meant where I installed it from?):
OneDrive

1. OS: Windows 10 Home Edition 64-bit
2. x86 or x64?: x64
3. (Only for xp, vista, 7): Running win 10, so no service pack????
4. What was the original OS installed on system: Always had windows 10
5. Is the OS an OEM version or full retail version: according to windows script host, OEM_DM channel (dunno if me reinstalling windows (this was before audio problems came along) made it different though)
6. Age of system (hardware): 1/25/2021 (25/1/2021)
7. Age of OS installation?: 1/3/2022 (03/1/2022)
8. Have you reinstalled the OS?: Once did in the past, but not since the issue came around
9. System Manufacturer?: CLX Gaming
10. Desktop
11. Exact Model Number: Unsure how to find it on desktop
12. Motherboard: MSI MPG X570 Gaming Edge Wifi (MS-7C37)
13. CPU: AMD Ryzen 7 5800x 8-Core
14. RAM: Patriot Memory, unsure which model, using 2 and 4th slots on the motherboard
15. Graphics Card: MSI RTX 3060 Ti Gaming X Trio (or just NVIDIA GeForce RTX 3060ti)
16. PSU: Thermaltake Smart 700W
17. Driver Verifier: Enabled
18. Any security software: None, I just have the built in windows defender
19. I do have a vpn, just hardly use it. Mullvad vpn
20. No disk image tools
21. Not overclocking

xilolee · Apr 22, 2023

There are new bios and chipset drivers on your motherboard support webpage.
Try to install them (follow the instructions they provide): MPG X570 GAMING EDGE WIFI

If you are unsure about something, ask!

ItsYaHomie04 · Apr 22, 2023

I installed the amd chipset drivers a few days ago, should I also try those on-board audio drivers as well? If not I'll get a usb drive ready for a bios update

xilolee · Apr 22, 2023

Honestly I didn't check if you are using realtek drivers and the nahimic program associated with it (if I understood correctly).
If you do, then it could be worthwhile to update it too.

ItsYaHomie04 · Apr 22, 2023

There is Nahimic Mirroring Service in device manager, and I don't use the realtek drivers

xilolee · Apr 23, 2023

Hence, did you update the bios?

ItsYaHomie04 · Apr 23, 2023

I will update bios once I finally have an empty usb drive to load the update file onto

ItsYaHomie04 · Apr 23, 2023

Bios update fixed the problem, thanks for the help

xilolee · Apr 23, 2023

Good to hear!
