Hello, I´d installed window 7 32bits, and my soundblaster live 5.1 dead, then I installed kx 3550 drivers and ...........wow, its alive, but in winamp rears speakers don´t work. Testing speakers return me "failed to create sound", but testing in windows panel control all is ok. I tried to change to 5.1 front=rear in sourrander panel but don´t work. In control panel is master mixer the selected playback device. Thanks.
