NOTE: The app produces various files, off course you do not have to use them all:
Use aDummyHDA.kext + edited config.plist for Clover (Ozmosis works similar) For all other bootloader use the full patched AppleHDA.kext (+ HDAEnabler.kext or DSDT edits... not both). Use CodecCommander.kext if the sound does not work after the sleep (wake), read more here. aDummyHDA.kext goes in /System/Library/Extensions
