But my question was: if you plug to an external mic jack and leave the headphone jack, the speaker noise is still there, right?
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.
I see.
Turning EAPD on/off on node 0x14 makes difference?
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. :)
(note that this may be obvious to you, but I don't understand what's EAPD on 0x14 so I'm just explaining what I hear ;-)
It's something like: hda-verb /dev/snd/hw0D0 0x14 SET_EAPD 0x00 to turn off, and hda-verb /dev/snd/hw0D0 0x14 SET_EAPD 0x02 to turn on.
Also, try to mute all sources in NID 0x0b, hda-verb /dev/snd/hw0D0 0x0b SET_AMP 0x7480
