I just made the jump from Dish to all streaming with a Roku Streaming Stick +. My TV connects to a Sony audio receiver via optic cable, which worked through the Dish remote. I can get the Roku remote to control the TV speakers, but when I change the setting to Optic, it doesn't work. Any ideas?
FWIW, using the TV's native remote also works - when using the volume buttons, it shows on the screen the signal is being sent to the Optic connection and controls the volume.
Maybe I'll try swapping out the optic cable for HDMI from audio receiver to TV.
