I tested it now (both "1" and "2"), but it does not make any
difference...

By any chance, have you attempted the position fix quirk, as documented here?

I tried "aplay -D pulse" and "aplay -D sysdefault:CARD-PCH" and
it is all the same, no matter if I play over pulseaudio or not.

I already asked for help on pulseaudio-mailinglist and they said
if I hear crackling even when playing sound without pulseaudio,
then problem must be elsewhere...

And when I hear clear sound with "that other evil OS booted",
then I can exclude hardware problem too. So it must be either
driver- or alsa-related...

Hello there,

Here's a workaround:

https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches.2C_skips_or_crackling

Tested on the ALC898 (5.1 surround sound system) on Ubuntu 16.04LTS,
as set up here:

      Hi ALSA-users,

      I have problem with sound on my PC: it is somehow distorted,
      "crackling" every few seconds. No matter what player or media
      I try, it is always there. I can hear it even when log-in
      desktop sound is played...

      Motherboard has Realtek ALC892 chip. Nothing new, but still
      used with many other mobos. I tested aplaying sound directly
      without pulseaudio, crackling is still there.
      Any idea how I could fix it?


Sometimes "crackling" is a hardware - electrical problem, such as a
broken
connector or cable.  What are you using to listen?  headphones into the
headphone output, speakers into the speakers output, S/PDIF into a DAC?
Do
you have other configurations you can try - headphones, speakers,
outputs?

C'est ma façon de parler.



I do not think this is hardware problem. I switched drives
and booted from the old one with Windows7/64b again: sound
is clear without any crackling...
