@fisherwei

try using the latest kext that I have attached.

DSDT editing is required

or use a HDAEnabler.

Used the latest kext that you attached and add DSDT patch from b1gdadd1 (page 1 #20) or add HDAEnabler=Yes/HDEFLayoutID=0x0C000000 into chameleon plist.

But, not any devices listed in Hardware/Audio.

 

If change to kext that I modified and same DSDT, devices can be found in Hardware/Audio, but also not work.

(My kext + chameleon HDAEnabler/HDEFLayoutID = no devices listed)

 

Kindly, please advise. @Mirone

In the Hardware/Audio, and don't have any devices in output/input.

AppleHDA.kext/            AppleHIDMouse.kext/       AppleHSSPISupport.kext/

AppleHDA.kext.bak/        AppleHPET.kext/           AppleHWAccess.kext/

AppleHIDKeyboard.kext/    AppleHSSPIHIDDriver.kext/ AppleHWSensor.kext/

Before in 10.8.5, my alc662 can be drived by 3 kexts(download from osx86.com), but 10.9 cannot.
