Re: Optimized AppleHDA for Realtek ALC 888 on Lion Edit dsdt.aml/HDEF as shown in the 1st Post of this thread. Delete S/L/E/HDAEnabler888.kext as it is not needed with a dsdt. Repair permissions, rebuild caches and restart. The front panel mic and front panel headphones show in System Preferences/Sound only when a mic and/or headphone is plugged in (automatically switches). It is not working at the present time because of the incorrect dsdt/HDEF. Reply with a copy of IOReg after the edits.
