sound is easier than wifi, let's go step by step
There are several ways to get the sound working.
1. The easiest way is to use VoodooHDA : http://www.insanelym.../728-voodoohda/
2. you can run toleda's scripts as the second way to enable the sound audio_codecdetect.command, run the command, take a snapshot and post it here
Got my wi-fi working already with some atheros kext.
