I posted the question before but it just disappeared anyway. I have a laptop that got optical output in 5.1 channel but the amplifier that i have got 5.1 input in RCA connectors only which are 6 different for every speaker. Is there any way that i can a converter or optical processor to do the job for me which will take in Optical and will give out audio in rca connectors. Or is there any other way to connect?? Please!!!!!!
