The strand thing that it's working perfectly in AIMP3 , but when I'm playing a movie in classic media player or YT video, only the center and right speakers are working . The others have this weeird , super low delayed sound , barely Noticeable .
This is my motherboard , maybe I've downloaded wrong drivers
or something, but I'm pretty sure that before reinstalling my Windows 7, I had this user friendly configuration tweak with sound options . Now it seems to be gone . http://www.asus.com/Motherboards/AMD_AM3/M4A88TM/
