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...?
