Try with this DSDT:

DSDT.aml.zip

where I've changed the PinConfigurations part of your HDEF device from this:

                        "PinConfigurations", 
                        Buffer (0x04) {}

to this:

                        "PinConfigurations", 
                        Buffer (Zero) {}

 

If you still get no joy with AppleALC, try to:

  • remove AppleALC
  • replace the vanilla AppleHDA in /S/L/E by the patched copy below
  • install the dummy IDT90HD92 kext below in /L/E
  • repair permissions to /S/L/E + /L/E
  • rebuild your cache

AppleHDA.kext.zip

AppleHDA_IDT90HD92.kext.zip
