I currently have my Roku hooked up with an HDMI connectcion and it works fine--thru the speakers in my t.v. set. My surround sound system does not have an HDMI output, so I am looking for a way to be able to play my audio through my surround sound system instead of my t.v. speakers. I'm pretty sure that the component cable/RCA cable is the way to solve this problem, but I'm not sure how. Help!!
