I have done all of these steps mentioned and I have also reset the device back to factory settings, and I am still unable to get the sound. I have tried every audio setting mentioned, I have restarted, I have unplugged I have switched HDMI ports, I have checked the volume, I have sound on the regular tv but as soon as the Roku is used NO SOUND.
The sound worked one day. Turned it off and the next day it would not and hasn't since then. I have spent three darn days trying to get the sound to work and the support simply is not good. Please assist in any way possible.
