This might be a kernel issue and not just a problem with Ubuntu since
I've had this exact same issue on an HP Envy 13 i5 Kaby Lake running
ALC295 on pretty much every distro. Back when I'd dual boot, I used to
boot into Windows before booting back into Linux to fix this problem and
it worked on every distro. Now I have a machine with only Linux on it
can't seem to make this issue go away. Here's a list of the audio
devices used.

Title:
Crackling and popping sound when using headphones
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Laptop is HP Pavilion - 15-au118tx. The laptop has B and O play and
the output from speakers are just fine, when using headphones there is
some kind of crackling and popping sound in both ears but prominently
in the left ear.
The issue happens only when the sound is played, if i reduce the PCM
way low using alsamixer, the effect is minimized but the volume is
also reduced. Increasing the volume in the panel increases the PCM as
well.
