I have four speaker which are fitted at my ceiling of the my house and I play them through my DVD(5.1 Channel) and Sony music player. Each speaker is having two wires total six wires(connecting). In PC we generally use green port(single port) for our 4.1 or 2.1 or so channel music for computer as common port for all the speakers of the computer . Now I want to connect all my external speakers to the common green port of the PC so that I can get music through my PC to the speakers. Is it possible to do so, if yes, What should I do ?
