last time i installed leopard i found the drivers i needed through a simple google search but now i have installed leopard again i cant find them, i have tried many different ones and none of them work. Also at the time i searched i didnt even know that sound card was sgmatel and i still managed to find them.

also when i go into sound prefrences its says no output devices found, last time, even without the correct drivers it detected some onboard hd audio thing.

my sound card is a sigmatel high definition 92xx

EDIT: I think it only worked last time because i used some headphones with inbuilt sound card
