i've already done any kind of installation methods ... still not working, and then when i checked on asus website All of maximus xi models have supremeFX with SS3 integration except for APEX model , only SupremeFX.. no sonic studio integration mentioned. so i guess this mobo is only superrior on its VRM than the other models with less features..
Indeed, the ROG MAXIMUS XI APEX motherboard is not SS3/SR3 compatible.
You must use HDA FF00 drivers (Realtek HD Audio Drivers with Realtek HD Audio Manager Only (Standalone) case, use the FIRST INSTALL/CLEAN INSTALL tutorial) : https://rog.asus.com/forum/showthread.php?105878-DRIVERS-Realtek-HD-Audio-(HDA)
