Sound crackling/popping

Another thing to consider trying is; completely uninstalling the sound card listed in system devices in the device manager; rebooting; letting windows re-detect and reinstall the drivers for the sound card; then go to the sound card manufacturers site and see if there are any updated drivers for your card and download and install them and see if that resolves the issue. Sometimes i believe what can happen is for one reason or another; something within windows will "Corrupt" the audio drivers which can possibly cause the issue you are having. Give this a shot and report back if it doesnt and we can try and go from there.

I have tried both, deleting realtek drivers and let windows download them back, and also manually download from realtek website.

Here is two sound recordings. Using speakers, not headset and problem still exist.

In this video i turn volume completely off and then back on

In this video I only change volume, but i keep it on and wont turn off at all. Using some low sound and bass turned to low.

It happens only when I am adjusting volume or start/stop video

Try connecting your front panel audio and plugging into that with the headphones.

Connected front panel audio to Mobo, exactly same thing there.

Strange, I tried my old computer (bought some cheap GPU and RAM) and it still has same crackling problem, and my new built system has it also? Also bought new GPU to this new computer, only RAM exists from old computer, but that shouldnt be the problem because got new ram for old computer and its still crackling.

What the hell.



What is that CPU throttling? how I can disable it?

Ok made new test with latencymon when I was playing and using mumble
CONCLUSION
____________________________________________________________________________________________________ _____
Your system seems to have 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 0:06:18 (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): 1383,111268
Average measured interrupt to process latency (µs): 3,409666

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: arma3.exe

Total number of hard pagefaults 263
Hard pagefault count of hardest hit process: 84
Highest hard pagefault resolution time (µs): 1509260,805396
