I have a samsung soundbar model E250 soundbar and a Samsung LCD tv model #LN46C610N1F . I can't seem to get any sound at all. My TV does not have ARC. It only has Optical out for audio. My sound bar only has HDMI in-port connection. What do I need to buy to get this hooked up

Your speakers have also 3.5mm AUX input (Manual, page 7, item #9). So you can get optical-IN-to-RCA adapter, and RCA-to-3.5mm cable
