Known issues

No Mic on AMD:

This is a common issue with when running AppleALC with AMD, specifically no patches have been made to support Mic input. At the moment the "best" solution is to either buy a USB DAC/Mic or go the VoodooHDA.kext method. Problem with VoodooHDA is that it's been known to be unstable and have worse audio quality than AppleALC
