AppleHDA for ALC727 (Realtek/Intel HiDef) Laptops

[smartie77]

 

APPLEHDA.kext for Realtek (ALC) 727 HDA // Intel HiDef ( for example in Toshiba L500 )

 

kext works in 10.6.8 Snow and 10.7 Lion , 32+64bit

 

 

 

KEXT : AppleHDA.kext.zip( put in S/L/E , remove all other Sound kexts )

 

**might work with HDAEnabler/LegacyEnabler** , but works 100% with DSDT mod as follows :

 

copy and replace entire (HDEF) section in your DSDT,recompile and put in /extra or EFI partition whatever you use.
