cracking/dropout audio problem.. (DPC?)

[Jaewoong]

Hello. I am first to this forum..

I have an audio problem. it is cracking.

I searched the Internet and tried several solutions suggested : updated GPU driver and sound driver, and command "verifier /reset"

There were some changes on LatencyMon, but the sound is still cracking.

Please help me..

thank you . I will answer the first question ASAP

The most visible problem is you are using two or three firewalls:

• windows firewall service is running
• Kaspersky Internet Security includes a firewall module
• MyFirewall 4.0 Service exists on your machine, even if it's stopped

Remove MyFirewall 4.0 completely, if you are not using it, and re-check windows firewall status (it should be enabled either windows firewall or Kaspersky firewall).

[Jaewoong]

Thanks for your kindness.

I turned off Windows firewall.

(sorry for language)

and I removed MyFirewall 4.0 from my PC.

So Kaspersky is the only firewall on my PC.


After all
Unfortunately, the audio is still cracking..

Here is my new trace.etl after disabling and removing : https://1drv.ms/u/s!AkTRHfXmXU1sg9JmhDsMFPrqsN79tA

thank you.

Is nProtect (nossvc.exe, nosstarter.npe) another antivirus? If yes, uninstall it (or use that instead of Kaspersky... I.e., use only one antivirus).

Try to update (or reinstall?) the driver(s) for your network adapter.
If your NIC is realtek RTL8168, it should be this: realtek.com.tw - Win8/8.1 setup for RTL8168 (click)

That should work also for RTL8168B, RTL8168C, RTL8168E, and other models... See next link:
