Crackling and popping sound when using headphones

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.
