Hello, any news on the matter?
Stupot, does it happen to have some USB bridge cards in some disk enclosure connected to the PC and powered on when the pops occur?
I have two, on a different controller than the soundcard, but playing from the two bridge cards.
The cards are based on JMicron chips, that had an old firmware, I call those "first generation firmware".
They had an issue I've found lately - could not support larger than 4TB disks unless the firmware was upgraded to a "second generation firmware".
After this, the pops disappeared.

Off topic, being JMS539 chips, have a sleep timer, that render the devices in an unrecoverable state, until the power down and on again, but I was lucky enough to solve the problem with the cards manufacturer (Lycom) that worked side by side with me and insisted to JMicron to get a "sleepless" firmware, despite the chips end of life was declared 4 years ago by JMicron.
I've seen a lot of trouble with these chips, and newer, regarding this sleep policy (probably due to the new environmental laws, but incorrectly applied technically speaking, IMHO). I hope you'll have the same chance with yours too, if it's the case.
For an idea, look here:

I happened across this article today and I'm hopeful, because it matches my system specs (AMD, Ryzen, X370). Not sure if you'll fall into the same boat. https://www.phoronix.com/scan.php?page= ... t-Audio-WA

I didn't have any issues lately, seems that it is fixed.

Wrong! It's back!
Stupot, can you confirm?
I did not change any hardware, I've only updated the system.

The pops are now unbearable. It does not matter the volume, the pops are at maximum!
What fixed them for a while? Why are they back? Is it a regression?

Interesting. I actually haven't heard any for a while. But it's hard to even recall if I made a tweak that helped or not. I was trying lots of random things and it's been a while....

Mine could have been fixed by the article I mentioned previously. The timing lines up, but I can't say for sure.

Yeah, the same, I don't remember what fixed it. I've tried lots and seemed to work out of the blue. And so came back. Possibly some upgrade overwrote some file... I wish I could reset the setup somehow. As freshly installed. But I don't even know what packages are involved. Or what driver, if there's any. It's a pain.

I just looked, and I don't have any special settings in /etc/pulse/daemon.conf like I had previously tried. I never attempted to change any kernel parameters or compiling anything special. I think my issue was most likely addressed with the workaround implemented for AMD Ryzen systems that I linked in the phoronix article, and nothing that I ever did.

Thanks. I don't have an AMD, but it seems to be less aggressive lately.
I'm baffled.
