Solved! How do I connect my new RokuTV to my old audio receiver?

Feb 9, 2019
I want to enjoy better sound than my TV's crappy speakers provide when I watch streaming or whatever on my new Roku TV. The TV has no RCA ports and the receiver doesn't have HDMI. TIA
You can get an adapter for whatever audio outputs the TV does have to the inputs on the receiver. Most likely would be optical out to RCA or something along those lines.
