Re-use the AppleHDAworking the Mics + IOAUDIOFanily.kext.repair permissions rebuild caches.for your IOREg use this: IORegistryExplorer
The audio situation is still the same. The moment I use the patched IOAudioFamily, it prevents the audio from working. Using the stock IOAudioFamily produces the results I mentioned above (mic input working on the first micfix, but not the second, etc.). This IOreg is missing the audio device because AppleHDA isn't loading to begin with, because it doesn't like the patched IOAudioFamily kext.
