I have a Samsung smart TV which was set up with surround sound a few years ago through a MX-890 universal remote. I then installed a Roku a couple of years ago but decided to upgrade it to one where I can control the TV ON/OFF and volume through the Roku controller only. Well, I just connected the new Roku with the HDMI cable and USB power cable and it set up fine and I can turn the TV on and off through it. However, I am only getting sound from the center speaker using the Roku. I can still get surround sound using the MX-890 remote. I checked the audio settings for the Roku and it is set to auto to get the best digital sound. How can I get the surround sound by controlling the volume on the Roku controller?
