asus a7n8x in 5.1 suround

Imam plato asus a7n8x, win XP in zvočnike Creative 5.1. Ali kdo ve kako se vključi 5.1 suround na tej plati. Na asusovi strani sem prebral da ta plata to podpira, na nekih forumih pa, da to podpira samo deluxe verzija. Poizkušal sem že vse. Imam vse nastavljeno kot piše tu:

If you wish to adjust audio to 5.1 channels under WinXP, please go to Start -> Program -> Accessories -> Entertainment -> Volume Control -> Advanced -> Other controls. In addition, check if Rear speakers are connected to Line-in, Center speaker and Subwoofer is connected to Microphone,?Front speakers are connected to Line out.

vendar še vedno ne dela ( dela samo line out ).

Za odgovore se vnaprej zahvaljujem !
