Thanks MaLd0n, but still no joy. Have followed the instructions, deleted kexts from everywhere except /Other, tried all the layout ids available, performed the HDAS to HDEF patch, but nothing. One thing I noticed when running DCPIManager is that I don't have my Realtek ALC887 codec listed in audio device like in your example pic in the audio instructions page. Is this a problem I need to address?
