Hi --- I have a receiver that I use when I watch a TV show or a play a DVD, so the sound comes out of my TV speaker as well as my four external speakers in my living room. The speakers are wired to the receiver. But when I hooked up Roku yesterday, the sound came out only from my TV. I figure I missed something on a setting. But I don't know if it's on Roku, my TV or my receiver. I don't know if it matters, but the other end of my Roku cable is plugged into a wall socket and not a USB port on the TV because I got a message that said the TV did not have enough power to run Roku. Any suggestions for proper connection would be appreciated.
