[SOLVED] Kernel 4.15 - glitchy headphone sound when inactive

Hello,
I don't know where to start, so I will just describe the problem then maybe someone (with some more experience) will tell me where to go next...
So after recent 4.15 kernel update when starting to work in desktop environment I start to hear cracking noise from speakers that are connected to headphone jack. When I start playing any sound the cracking stops, but after few seconds when no sound is playing I start to hear the cracking again till I start playing any sound or attempt to mute/unmute headphone output.
The cracking also happens even if I mute the output.
No additional logs in Xorg or Journald and I don't know how to bite it..
It's pretty annoying...

OK, solved it.
Power saving feature of snd_hda_intel was causing it. So I turned it off:

options snd_hda_intel power_save=0
