Hoping someone can help before I purchase. I have a 2016 Samsung Smart TV and a Sony Surround Sound System (much older) that is hooked up through the TV. My Samsung TV cannot access some streaming channels due to outdated software so I was looking at getting a streaming box to assist. I am a bit confused reading about audio systems and wondering if I will have to reconnect my surround sound to the Roku box in order to work. If so, it will be useless because the cables are the old colored cables which the Roku do not have available. Can I leave it hooked up through my TV (it is also hooked up so it works with my BluRay player)? Can the remote be set up for the volume to be used with the surround sound system and not the TV? Thank you for any help!
