In fact I don't have jack in 'Front Headphone Jack', my jack is plugged in 'Line Out Jack':

1) Fix did not help:
> Then edit /etc/modprobe.d/alsa-base.conf and add this line:
> options snd-hda-intel jackpoll_ms=250
However this fix (or maybe together with the second fix) made sound interruptions to appear more rarely (e.g. once in a minute instead of once in several seconds).
Tried jackpoll_ms=250,250 and jackpoll_ms=1000,1000

2) Fix did not help either:
Commenting out the following in the
/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf

#[Jack Front Headphone]
#required-any = any

#[Jack Headphone]
#required-any = any

3) Fix did not help:
ALSA level: start alsamixer in a terminal and change "Automute mode" to "disabled"
On my system I basically don't have 'Automute mode' option

4) The only solution helped is to physically disconnect front panel audio connector on the motherboard. Only then those sound cracking and popping disappeared completely.
