This is Mavericks 10.9.2 AppleHDA 2.6.0f1 patched to work with ALC662.



I used VCH888's patch from Insanelymac, so thanks to him for the binpatch!



I made this to my Gigabyte G31M-S2L, but maybe it works on other boards too.



- LineOut (tested,works)

- Headphone(autoswitch) (tested,works)

- RearMic (tested,works)

- frontMic (not working)

- LineIn (not tested but it should work)

- SPDIF (not tested but it should work)



You need these in your DSDT:

Device (HDEF)

{

Name (_ADR, 0x001B0000)

Method (_PRW, 0, NotSerialized)

{

Return (Package (0x02)

{

0x09,

0x05

})

}

Method (_DSM, 4, NotSerialized)

{

Store (Package (0x06)

{

"built-in",

Buffer (One)

{

0x01

},

"layout-id",

Buffer (0x04)

{

0x0C, 0x00, 0x00, 0x00

},

"PinConfigurations",

}, Local0)
