Hi, i have 4 speakers and a subwoofer. Mainboard is asrock xtreme4 which come with realtek hd audio. You may know the famous "rear speaker problem" on windows products. While speaker test just works fine, rear speaker never works on media player, winamp etc... But recently it become really interesting because, that rear speakers works fine on firefox browser 22.0. So it gave me hope the solve this problem once and for all. Right now, when i listening any thing on firefox, rear speakers works fine. But not working on Chrome and other stuff. What firefox 22.0 made to work speakers fine?
