Yes. It was mentioned that PIN_VREFHIZ works too.

Yes, that's how the quirk-patch came out (I've zero knowledge of
sound/alsa development, I was just asked to cook a patch based on that
suggestion, as nobody was doing it).

Tried latest of both, yet no luck out-of-the-box.
Still have to apply the quirk-patch or manually change via hda-verb
each time to have a working sound output. 

Ciao, Luca
