I can confirm witht he p8z68v- pro/gen3 that the provided dsdt crashes.. I've made my own and it works ok, don't know what advantage I'm getting. I can use Toleda's apple hda for audio over sp/dif, but still no 5.1 / 7.1 and no hdmi, those changes keep crashing my dsdt. (I'm doing something wrong and still experimenting)...
