So, I first uninstalled my realtek drivers (control Panel/Uninstall Programs/ Realtek) then installed the beta driver directly from asus. After the reset I tired it out with my astro a30's (no mixamp) and the sound was horrible so much echoing with no bass at all. I used my a30's with no amp before and it wasn't this bad. I tried messing with the settings that didn't work.
Also For some reason the S/pdif out is always checked on the menu.
Funny thing is when I have my z623's in the front Out it works fine only not with spotify. It wont play, says something is wrong with my soundcard... *sigh
