I have a roku streaming device (not the stick that goes directly into the hdmi port). It has 2 connections in the back of the little box for hdmi and power. I normally connect it directly to the tv. I have a Samsung sound system (with a blue ray disc player) that I want to hook up to the tv and roku. The back of the sound system has only one hdmi connection, an optical connection and the connection for the cord with the different colors (sorry I can't remember the name lol). Is it possible to have the roku sound go through the sound system? I do want the best sound possible. Any suggestions will be VERY much appreciated. Thank you so much! =)
