Hi, it'd be glad to have patch_cirrus.c recognize model=imac27_122, (i'm adding a model because it's harder to auto-detect it), please find attached patch, tested on linux 3.2-rc7. I don't know anything about pin configs, just that it works with the ones in the patch. Note that i tried with model=auto (no sound) and model=imac27 (front speakers not muted when headphones are plugged in, and surround speakers not properly detected).
Thanks for the patch. But I see a problem in the code, i.e.
+static const struct cs_pincfg imac27_122_pincfgs[] = {
- { 0x00, 0x821c9700 },
- { 0x01, 0x011d9700 },
(snip)
- { 0x27, 0x401f5701 },
- {} /* terminator */
+};
This looks obviously wrong. The pincfg table should contain only the default pin-configuration values for pin widgets while you are setting some values to all widgets. Please minimize this entry.
It's working without overriding pin-configurations :) I tested almost everything except digital input/output.
A kernel with the following patch and options snd-hda-intel model=imac27_122 is enough to get sound working.
OK, that's much better. Could you give the patch with a proper changelog and your sign-off so that I can merge it now?
ALSA: hda/cirrus - support for iMac12,1 and 12,2 models
Those models just need to have headphones on GPI02 instead of GPI01, and use BIOS pincfgs.

Could you check whether the device has a unique PCI SSID (check lspci output), and add the corresponding entry to cs420x_cfg_tbl[]? If it's about 10de:xxxx, it should be unique. If it's 8086:xxxx, then we'd need to check the codec SSID instead of PCI SSID.
The PCI SSID is 8086:1c20 How can i get the codec SSID ?
Check /proc/asound/card0/codec#* file. This id should be added to cs420x_codec_cfg_tbl[], but before the entry SND_PCI_QUIRK_VENDOR(0x106b, "Apple", CS420X_APPLE) which matches all 106b:*.

I get Vendor Id: 0x10134206 Subsystem Id: 0x106b2000
