[alsa-devel] HDA_PINCFG_NO_HP_FIXUP question

[David Henningsson]

Hi,

I'm trying to fix a bug where the docking station is not working. I 
started by adding pins for them (because that was not present), like this:

	[ALC269_FIXUP_LENOVO_DOCK] = {
		.type = ALC_FIXUP_PINS,
		.v.pins = (const struct alc_pincfg[]) {
			{ 0x19, 0x23a11040 }, /* dock mic */
			{ 0x1b, 0x2121103f }, /* dock headphone */
			{ }
		},
	},

However, this caused the real (non-dock) headphone out to "fixed up" to 
a line out, which is wrong. I'm a little unsure about the best way to 
resolve this, I can think of a few different options:

1) Also override the non-dock headphone out to have sequence number 0xf

2) Set parse_flags to HDA_PINCFG_NO_HP_FIXUP in patch_alc269

3) Try to improve the fix up algorithm to not fix up this particular 
case, but since I don't know when and where this was needed in the first 
place, I'm not sure how to do that without throwing the baby out with 
the bath water...?
