I was using old but awesome tower speakers with my Yamaha receiver. I bought an Energy soundbar that only has optical and RCA connectors. I can not get any device such as cable box, dvd player or what not to play out of the Energy soundbar. I have to run an RCA from each component to the soundbar. I can get the radio to play though the receiver and out of the soundbar. Everything is connected to the receiver by HDMI, should i switch to RCA for everything?
