Oh. If I understand correctly you're talking about 2 jacks, but there's
only one jack on this laptop, doing both mic and speaker.

Yes, turning it off makes the noise disappear. But I can't hear
anything, e.g. playing music makes no sound unless I turn it back on. :)

EAPD on 0x14 so I'm just explaining what I hear ;-)
