biox78 Posted October 7, 2011 Share Posted October 7, 2011 After months of reading threads, finally I've found a solution to use AppleHDA on ALC887!!! First, you have to modify your DSDT in this way: - into the Method (_L0D, 0, NotSerialized), add the following: Â Notify (\_SB.PCI0.HDEF, 0x02) Â - Add an HDEF Section under the PCI0 device with the following lines: Â Device (HDEF) { Name (_ADR, 0x001B0000) OperationRegion (HDCS, PCI_Config, Zero, 0x60) Field (HDCS, DWordAcc, NoLock, Preserve) { VID0, 16, DID0, 16, Offset (0x4C), DCKA, 1, Offset (0x4D), DCKM, 1, , 6, DCKS, 1, Offset (0x54), , 15, PMES, 1 } Method (_PRW, 0, NotSerialized) { Return (Package (0x02) { 0x0D, 0x05 }) } Method (_DSM, 4, NotSerialized) { Store (Package (0x0E) { "subsystem-id", Buffer (0x04) { 0xA0, 0x00, 0x00, 0x00 }, "subsystem-vendor-id", Buffer (0x04) { 0x86, 0x80, 0x00, 0x00 }, "codec-id", Buffer (0x04) { 0x85, 0x08, 0xEC, 0x10 }, "layout-id", Buffer (0x04) { 0x77, 0x03, 0x00, 0x00 }, "platformFamily", Buffer (One) { 0x00 }, "MaximumBootBeepVolume", Buffer (One) { 0x40 }, "PinConfigurations", Buffer (One) { 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } Â - copy modified DSDT on root and inside E/E Then do the rest: - install LegacyHDA_ALC887.kext in E/E - install AppleHDA.kext 1.7.9 in S/L/E - repair permissions in E/E and S/L/E - reboot - once rebooted, verify in System Profiler/Audio if all is recognized correctly, and choose in System Preferences/Sound "line-out" for the output.
