High pitch noise in headphones

I can hear high pitch noise after some time in headphones.
Headphones connected into jack input by cable.
Even recorded it by iPhone and extracted and amplified with Audacity, you can hear 2 seconds sample here (Warning! LOUD):

It disappears right after connecting/disconnecting laptop to power adapter, but returns after some time (5-10 secs).
It disappears if I press mute for headphones output, and returns when I unmute.
It disappears after pulseaudio -k, but returns after 3 seconds of playing youtube video in Firefox.
