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.
