Hey all,
When working out an issue for a person in #alsa, i found that the onboard sound in their laptop (A110-225) has the Subsystem IDs 1179:ff01 . The card has an ALC861 codec.. the issue (non-fatal thankfully) is that the above mentioned Subsystem IDs match in patch_realtek.c to 'dallas' which is for an ALC861VD codec..
SND_PCI_QUIRK(0x1179, 0xff01, "DALLAS", ALC861VD_DALLAS),
The user was getting the non-fatal:
hda_codec: Unknown model for ALC861, trying auto-probe from BIOS...
in dmesg..
Note that this is *NO* error or warning at all. This is nothing but a info. Ideally, all hardwares should be handled in that way. Only hardwares that don't work with auto-probe should have the preset.
I had the user force the 'toshiba' model (which is valid for ALC861) and the warning went away, and sound continues to work as it should..
Just wanted to make sure this problem (even though non-fatal) is documented, and we are aware of it. Perhaps this laptop, and the 'Dallas' need to be matched on some other level.
ALC861 and ALC861VD are different codes, so they have independent preset tables. Maybe that's why.
