Do you mean setting the pinctl 0x22 (PIN_VREFGRD) to NID 0x19?
Yes. It was mentioned that PIN_VREFHIZ works too.
Changing this via hda-verb with model=auto state also fixes the issue?
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).
For the kernel, try: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git For alsa-driver snapshot, try: ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz
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.
