I have a HP-Laptop - 15-dw2084ne and a few days ago I noticed a buzzing/crackling/static sound coming from my earphones. I then found out that if I remove the charger, the noise goes away completely, and when I put it back on the noise comes back. I have tried different chargers and outlets but that does not do anything. Opening programs seems to make the noise be louder, and the noise is still there when I mute the audio. And the laptop speakers are fine.
I have the latest audio drivers, the noise is still there while using different earphones and headphones, all drivers are up to date.
Any suggestions? I just got this laptop in February.

EDIT:
I just found out that interacting with the keyboard such as changing the volume and the brightness makes a more louder static sound in my earphones.
Same for the mouse when I click and move

The underlying cause of the problem is perhaps interference on the 2.4Ghz bandwidth.
Search for articles and help to better determine whether this is your issue with your headset / headphones.
For example, search for "2.4ghz interference with headphones"
