I am trying to do this method but it's too difficult for me I have difficulties in chapter 2 with modifying AppleHDAHardwareConfigDriver.kext and also point 3 - Editing and platform.xml layout12.xml or Layout1.xml because when I open layout1.xml I get a different code something like this (xúÌ]Ys‚∫∂~Ó˚+rûSΩ—<ÏÍ€U¡d` »¯rÀÄÃ`¿ÿ8ÎØIw'qb pHÄ>N’fiù¿í,≠OZ£¥¸£m∑ºüˇs˛¸ËY≥ü%s6ÙΩ|ÓGfÒ◊Øœm«≥,˜'¸ë˘ÛÎKÉ™Èu Ê®f›ønb∫Æ˘˚˜ßø_ûÚ¸—Çÿ∂≠V‰aœ_øÈ·˘Û?#@L2…)AoıLòâÈ·È°«è^Ÿn≈=Û˝(üùYf{b-˛_;{”8 ) APÒ2∫ofl~¸Á˚˜o?‹∂È˛õ…0N ÚÁ7kÏ€S≥o9fiÅ7<8‰ˇÄvˆ‡˚w≈8 ægùVÛïe#@)

I tried this one http://www.osx86.net/view/3100-applehda.kext_alc272_mountain_lion_vers_...html no luck what should I try next ?

yes its layoutid 1 but unfortunately it doesnt work

These are my original and modified dsdt files for HDEF alc 272 can someone look and say if there is something wrong with it. Thanks dsdt-original.aml.zip dsdt-modified.aml.zip

I tried it but no success my mac is in french so I tried: dsdt=/Ustilisateurs/sahbin/Bureau/dsdt.aml and dsdt=/Users/sahbin/Desktop/dsdt.aml I also putted -v -f and AppleHda.kext loaded but still no sound and no icon.

hmm ok I will try this as soon as possible, thank you

I have booted with this line "dsdt=Desktop/DSDT.aml -v" to test the dsdt and to be safe in case I have a kernel panic.

I installed applehda.kext and rebooted but no sound and no icon of sound in the top bar

Here is what I have done can you say if its ok or am i doing something wrong first I have opened dsdt editor and i extracted my dsdt then I runned the AZAL to HDEF patch first and the HDEF patch donwloaded from this website (index DSDT patches) then I runned IASL but I got 7 errors I fixed them but there was one error that it couldnt fix it was DTGP so I found another patch on this website for DTGP and patched. all errors were fixed but there are still warnings. I saved the DSDT as in IASL (btw I changed 0x0C to 0x01. Now I will install applehda.kext downloaded for ALC 272. Am I doing it right ? Thanks

this is what ive made is it correct? Device (HDEF) { Name (_ADR, 0x001B0000) OperationRegion (HDCS, PCI_Config, 0x54, 0x04) Field (HDCS, DWordAcc, NoLock, Preserve) { , 15, PMES, 1 } Method (_PRW, 0, NotSerialized) { If (LEqual (WKMD, One)) { Return (Package (0x02) { 0x0D, 0x03 }) } Method (_DSM, 4, NotSerialized) { Store (Package (0x0c) { "built-in", Buffer (One) { 0x00 }, "layout-id", Buffer (0x04) { 0x01, 0x00, 0x00, 0x00 }, "PinConfigurations", Buffer (0x00) { 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } Else { Return (Package (0x02) { 0x0D, Zero }) } } } } } }

thanks for your quick reply but I am a beginner and I don't know how to patch AZAL to HDEF can you explan me ? thanks

Hello I have a laptop parchard bell lj65 with alc272 I installed AppleHDA.kext but when I go to my dsdt I cannot find HDEF. so I cannot patch my dsdt I only have AZAL Device (AZAL) { Name (_ADR, 0x001B0000) OperationRegion (HDCS, PCI_Config, 0x54, 0x04) Field (HDCS, DWordAcc, NoLock, Preserve) { , 15, PMES, 1 } Method (_PRW, 0, NotSerialized) { If (LEqual (WKMD, One)) { Return (Package (0x02) { 0x0D, 0x03 }) } Else { Return (Package (0x02) { 0x0D, Zero }) } }
