[SOLVED] High DPC latency and popping noises

[PC Cheah]

Hi, recently I've built a new pc, when I listen to music , watching videos or playing games. I will hear some popping noises (that's kinda annoying)
I ran the LatencyMon and it shows the PC have some DPC latency issues. I searched on Google for the problem and I tried many solutions(different forum threads) but sadly those ways doesn't fix my PC. So I decided to post another thread at here.

Things I've tried
-Updated to Latest BIOS
-Chosen High Performance at Power Options
-All drivers are updated to latest version (especially Realtek HD Audio Driver, Nvidia driver and Intel LAN driver.)
-Disabled all enhancements at the default audio device
-Defragmented HDD

My computer specs:
CPU: Intel i5-6500 @ 3.2GHz
RAM: Kingston HyperX DDR4 8GB 2400MHz (downclocked to 2133MHz)
Motherboard: ASUS H170 Pro Gaming
GPU: MSI GeForce GTX 1060 Gaming X 6GB
SSD: Samsung 850 EVO 250GB
HDD: Western Digital Blue 1TB

ALC1150 audio codec on the mobo​

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. 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 0:14:36 (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.

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.

Would you try these steps?

Preamble
In case you don't know how to open an elevated command prompt in windows 8.1, this is the simplest procedure: right-click windows start, click command prompt (admin).

• Left-click on Start, type directly msconfig, press enter.
  Is the radio button on normal startup?
• Launch this command from an elevated command prompt:

  dism /online /cleanup-image /checkhealth

  Do you get my same result?
  Read More:

  C:\>dism /online /cleanup-image /checkhealth
  Deployment Image Servicing and Management tool
  Version: 10.0.14393.0
  Image Version: 10.0.14393.0
  No component store corruption detected.
  The operation completed successfully.

• Advanced disk cleanup with cleanmgr:
  • Open an elevated command prompt
  • Type cleanmgr /sageset:1 and press enter.
  • Select all the options, or leave unticked the ones you prefer.
  • Type cleanmgr /sagerun:1 and press enter
  • Let it work until it finishes.
• Launch this command from an elevated command prompt:

  sfc /scannow

  If you get the following message:

  Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log

  Read Windows Update Forum Posting Instructions (click) and provide the necessary (and missing) informations to the experts.I.e., you should:
  • export and zip/compress the entire CBS folder on your desktop
  • open a new topic in the windows update sub-forum (in sysnative.com)
  • attach that zipped file to that new topic
  If the CBS compressed folder will be too large, you can check the second post on that thread (to use the sfcfix tool with a script) or you can use a (possibly fast) web service like MS OneDrive, Google Drive, DropBox, Box, Mega, Apple iCloud, Amazon Cloud Drive, and so forth...
  Instead if you get the following messages, go to the next step:

  Windows Resource Protection did not find any integrity violations
  Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.Log %WinDir%\Logs\CBS\CBS.log

• Check you system partition, then post the result here. Steps:
  • Open an elevated command prompt.
  • Type chkdsk c: /b and press enter.
  • You'll get:

    The type of the file system is NTFS.
    Cannot lock current drive.
    Chkdsk cannot run because the volume is in use by another
    process. Would you like to schedule this volume to be
    checked the next time the system restarts? (Y/N)

  • Type Y and press enter.
  • Then restart/reboot and wait until it finishes this check.
  • To find chkdsk result:
    • Open an elevated command prompt
    • Copy/paste this command and press enter:

      wevtutil qe application /c:1 /rd:true  /f:text /q:"*[System[Provider[(@Name='Microsoft-Windows-Wininit')]]]" > "%userprofile%\desktop\ChkDskLOG.txt" & notepad "%userprofile%\desktop\ChkDskLOG.txt"

    • It should create chkdsklog.txt on your desktop and open it: paste its content here.
    • If the command won't work, type eventvwr, press enter, in the event viewer window double-left-click Windows Logs to expand it, left-click Application, double-left-click the information event with source wininit, copy its content and post it here.
• Defragment your system drive (using windows default defragmenter). Steps:
  • Open an elevated command prompt
  • Type defrag c: /h and press enter
  • Wait until it finishes

After all those operations, reboot your machine and see if the problem persists.

sorry for the late reply.

I ran all the steps and it doesn't seems to reduce the latency, so I went to BIOS and tried enabling the Intel SpeedStep from "AUTO" and disabled the "Depop" at HD audio driver option in my BIOS and surprisingly the HDAudBus.sys has running better (no dpc latency problem) so the popping noise reduced a little. I ran a speedtest for no reason, I get a very high ping result 250~270ms (usually 19~23ms) and I refreshed the webpage and still get some high ping result. So I suspect that something is wrong with the Intel LAN.
P/S: STORPORT.SYS and NDIS.sys are still having a high DPC latency.

 

[xilolee]

Then provide the logs and I/we'll check them...

Possible problematic software: MSI afterburner and Bitdefender antivirus free.

RAM KHX2400C15/8G kingston 8GB

• pc4-19200 - DDR4-2400 (1200 MHz) - 1.2V
• not listed in the QVL of your motherboard (possible incompatibility?)
• I didn't find it on Kingston website
• CAS# Latency (CL - tCAS) 15
• CAS# to RAS# Delay (tRCD - tRC) 15
• RAS Precharge (tRP) 15
• Cycle time (tRAS) 35

Graphic Card MSI GTX1060 Gaming X 6G

• not listed in H170-PRO-Gaming_Devices_report (possible incompatibility?)
• I've found, as examples for compatible graphic cards (under ASUS, but probably also other manufacturer models could work):
  • GT 610
  • GT 640
  • GTX 690
  • GTX 720
  • GTX 730
  • GTX 740
  • GTX 750
  • GTX 750TI
  • GTX 960
  • GTX 970
  • GTX 980
  • TITAN-X

Now I'll look into the trace.

 

[xilolee]

I forgot another possible culprit: intel raid software.

I didn't find anything useful in the trace (maybe that's too advanced for me). Were you trying foobar2000 to reproduce the noises?

Try to uninstall MSI afterburner, intel raid and Bitdefender (use ms defender in the meanwhile).
Then reboot and see if the problem disappears.

 

[PC Cheah]

Still the same, storport.sys and ndis.sys high latency
the latency spikes everytime i open Google Chrome.
I need foobar2000 to listen to music, I uninstalled the MSI Afterburner, i didnt install intel raid software, and there are some problems to remove the antivirus.
maybe i have to try to reformat the os and reinstall everything?

 

[xilolee]

Try to download/run their tool: Bitdefender 2016 Uninstall Tool (click)
In control panel you could find intel rapid storage technology, IRST, intel RST.

 

[PC Cheah]

The antivirus uninstallation was successful. I didn't found any Intel stuff inside my control panel (except my cpu name).
There are still the same :thud:
The latency is fine before I open Google Chrome while I'm listening to music. Everytime I open chrome the NDIS.sys latency spikes.

1) Set bios default settings (load optimized defaults)
2) not sure about the versions of these files: iastora.sys, iastorav.sys, iastor.sys.
Maybe you can install the version provided by your MB manufacturer: ASUS H170 PRO GAMING Intel Rapid Storage Technology Driver software 15.2.1.1028 2016/12/14 (click)
3) install or reinstall ASUS H170 PRO GAMING Intel LAN Driver V20.2.3001.0 for Windows Win8.1 64bit---(WHQL) (click)
4) Check also if you have the (non-beta) versions listed in chipset, audio, vga and usb sections: ASUS H170 PRO GAMING Driver & Tools (click) (if not, install those versions)
5) Reboot and see if something changes.
6) If it doesn't, try to uninstall the intel RST (hopefully this time you should see it in control panel).
7) If it's still the same, provide a new trace (last hope)

I'm sorry that I've upgraded my windows 8.1 to 10. I have set the bios default settings,disabled "depop" at the hd audio settings
I reinstalled everything, and ran the latencymon(for 1 hour while playing some videos on youtube using chrome), the result i get show below.

_________________________________________________________________________________________________________
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. 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 0:27:13 (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): 665.021810
Average measured interrupt to process latency (µs): 4.537722

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 4944
Hard pagefault count of hardest hit process: 1248
Highest hard pagefault resolution time (µs): 611799.781642

[xilolee]

Did you install the default drivers present in your MB support page, intel rst included?

 

[PC Cheah]

I did install the Intel LAN, Realtek audio driver, asmedia USB controller, Intel USB controller and that's what I installed from the mobo support.

 

[xilolee]

Ok, install intel RST and check if that helps.
If it doesn't help, uninstall it and see how it goes.

Does this happens with Chrome only? Did you try other browsers?

Now I'll check your new logs/trace.

Edit:
I also checked the latest NVidia drivers and in their Changelog "says" [375.86, GP104] Corruption in YouTube video playback when two or more videos are playing at the same time in Chrome. [1843100].
Hence maybe this problem could also be caused by NVidia drivers.
