So i have bought a new samsung smart tv which comes with a external box with all the inputs and outputs but unfortunately it doesn't have a aux output and my old home theater system only has aux input. And i did some research online and found out that i can use a optical to rca converter to make the sound system work with my system. So i just want to ask here before i buy the converter that if there's any better alternative to it or not.
Here's the pic from the back of tv and home theater system.
You are correct, only really efficient way is to use an optical to RCA converter and connect that to the VCR inputs. Keep in mind that you will only get stereo sound that way, so if you want to have surround sound you need a newer setup with HDMI or optical input directly.
