PCI SSID is 1028:0685.
Codec: Creative CA0132 Address: 0 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x11020011 Subsystem Id: 0x10280685
Codec SSID is also 1028:0685.
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.
snd_pci_quirk_lookup() just returns a value matching in the given table. Provide a table like:
enum { QUIRK_NONE, QUIRK_ALIENWARE, };
static const struct snd_pci_quirk ca0132_quirks[] = { SND_PCI_QUIRK(0x1028, 0x0685, "Alienware 15", QUIRK_ALIENWARE), {} };
then somewhere in the probe, check the table
spec->quirk = snd_pci_quirk_lookup(codec->bus->pci, ca0132_quirks);
then refer it appropriately
if (spec->quirk == QUIRK_ALIENWARE) { spec->out_pins[1] = 0x0f; .... } else { spec->out_pins[1] = 0x10; .... }
The current ca0132 code has way too may fixed assignment, so the pin reassignment like other codec drivers doesn't work as is. We'd need to sort it out first. So, start from the simple workaround.
