I couldn't find any occurrence of SND_PCI_QUIRK() to mess up with in
patch_ca0132.c.
I gave a look at patch_realtek.c and got something like:

enum {
    CA0132_FIXUP_CORE3D_EX
}

static const struct hda_fixup ca0132_fixups[] = {
    [CA0132_FIXUP_CORE3D_EX] = {
        .type = HDA_FIXUP_PINS,
        .v.pins = (const struct hda_pintbl[]) {
            { 0x0f, 0x032110f0 }, /* headphones */
            { }
        }
    },
    {}
}

static const struct snd_pci_quirk alc861_fixup_tbl[] = {
    SND_PCI_QUIRK(0x1028, 0x0685, "Alienware 15", CA0132_FIXUP_CORE3D_EX),
    {}
};

But I don't know how to load this on ca0132.
It there any simple documentation about quirks? I fear this is beyond my
capabilities.
