Realtek ALC271X edited AppleHDA.kext_v2.3.7fc3

Actually it works fine in 10.9.2 but it should work in 10.8 (maybe starting from 10.8.3)

 

You must use layout 28 (0x1C, 0x00, 0x00, 0x00) in your DSDT or change the content of HDEF device in your DSDT like this:

Device (HDEF)        {            Name (_ADR, 0x001B0000)            OperationRegion (HDAR, PCI_Config, 0x4C, 0x10)            Field (HDAR, WordAcc, NoLock, Preserve)            {                DCKA,   1,                 Offset (0x01),                 DCKM,   1,                     ,   6,                 DCKS,   1,                 Offset (0x08),                     ,   15,                 PMES,   1            }            Method (_DSM, 4, NotSerialized)            {                Store (Package (0x16)                    {                        "AAPL,slot-name",                         Buffer (0x09)                        {                            "built-in"                        },                         "codec-id",                         Buffer (0x04)                        {                             0x69, 0x02, 0xEC, 0x10                        },                         "built-in",                         Buffer (One)                        {                             0x00                        },                         "name",                         Buffer (0x0F)                        {                            "Realtek ALC269"                        },                         "layout-id",                         Buffer (0x04)                        {                             0x1C, 0x00, 0x00, 0x00                        },                         "model",                         Buffer (0x10)                        {                            "Realtek ALC271X"                        },                         "device_type",                         Buffer (0x06)                        {                            "Sound"                        },                         "device-type",                         Buffer (0x25)                        {                            "High Definition Audio Controller"                        },                         "subsystem-vendor-id",                         Buffer (0x04)                        {                             0x86, 0x80, 0x00, 0x00                        },                         "hda-gfx",                         Buffer (0x0A)                        {                            "onboard-2"                        },                         "PinConfigurations",                         Buffer (Zero) {}                    }, Local0)                DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))                Return (Local0)            }

Thank you very much for your patched AppleHDA and its DSDT edit. It works like a charm with my ASUS X53E laptop running Mac OSX 10.10 Yosemite GM 3.0. Before this, I have to use VoodooHDA V2.86.MAV.pkg for audio.
