I already knew that it works through the tv's internal speakers. The problem is that there are many times I watch TV shows (like AMC's Breaking Bad and Mad Men) through my home theater surround sound audio system. Roku does not allow me to do that.
Dish gave me a free Roku but it is useful to me only as a paperweight.
