I have the Philips MMS205 which consists of 4 satellite speakers and a subwoofer. My sound card is a Soundblaster Live! X-Gamer. My satellites are properly hooked up to the subwoofer. The line IN on the subwoofer is connected to the line OUT on the computer, and the surround IN is connected to the Rear OUT on the computer. However, the problem is that only ONE of the satelites and the subwoofer are working, the other three satelites are not emitting any sounds. Please reply if you know what is wrong and/or what i can try. Thanks.
