Solve : Random audio crackling?

Answer»

I contact you because I have a problem that I can not solve. This goes beyond my computer skills.

Indeed, for more than a year and a half, the crackling sounds appear randomly when a video is launched. Mainly via web browsers but also via Windows readers. (Problem occurred suddenly, probably because of a software update of one of the components)

observations:
What's interesting is that the problem intensifies when the reading application is in the background. (reduction of a window, or at the back of another window).
The problem does not occur when I use an external sound card or use the audio source of the HDMI cable that comes out of my graphics card.

To be specified: when the problem arises, (Example on Netflix or Youtube), the sound is out of sync. the sound is offbeat (late on the image) with each crackle.

I made a video with the famous cracklings:

My attempts:
I tried to spot the problem by trying other components: Ram, Power, Case, motherboard, graphics card (except processor).

Updated CG drivers, reinstall windows, change port jack, change headphones, update bios, reinstall REALTEK drivers ...

I then contacted the support.

Intel tolds me :

I checked the reports you sent and I can see that the processor is working in the specifications.
In addition, the processor is not responsible for creating the sound, the sound card does it, in your case, the sound card NVidia.

Nvidia tolds me :

Je remarque que votre carte audio est une Realtek, je pense qu'il faut se PENCHER sur ce volet là puisque LE SOUCI n'est pas apparent si vous passez par le HDMI de la carte graphique.

Realtek still did not answer me...

My Setup:
I7 7700K intel (Dark Rock Pro 3)
GTX 1080 Gigabyte
16Gb Ram 3000Mhz Corsair Vengeance (Profile XMP Activé sur CM)
z270 tuf mark 2
Alimentation TX650M
Corsair Carbide 275R

SSD250GB (Os + software)
2To HDD (Jeux)
1To HDD (Documents)

Conclusion:
In my opinion, this is probably a software problem. A program interferes with the audio driver of my CM.

Do you have any ideas about this phenomenon?

Thank you in advance for your answer.

I disagree, but I have no proof. I think it is a defect in the sound chip.  Good and cheap sound chip replacements are easy.
A cheap USB audio solution can be found at amazon and other vendors.
Search for USB sound card adapter and find lots.

If your using latest drivers which were intended for your OS, I'd say avoid use of that sound device and use the others that dont act up. Does the audio/video sync issue happen with external sound card ( assuming USB) or HDMI from video card?Thanks for your replies !

No, because I've changed my mother board twice and the issue still here.

Yes, I think I'll do this if I cant solve the issue.

Do I have to  install old windows 10 version ?
