This completely shuts down the speaker: no noise, but no sound at all if I play something.

hda-verb /dev/snd/hw0D0 0x14 SET_EAPD 0x02 to turn on.

That makes it back to normal, with noise. :)

Also, try to mute all sources in NID 0x0b, hda-verb /dev/snd/hw0D0 0x0b SET_AMP 0x7480

This seems to not change anything at all.
