Re: Setup Roku Ultra with Dish and Samsung Sound Bar
Assuming your soundbar's HDMI/ARC port is connected to the TV's HDMI/ARC port, then you should be able to connect your Roku (and your Dish or anything else for that matter) to another HDMI port on the TV and the sound will route to the soundbar (assuming the TV is in ARC mode).
