Re: ISO soundbar for Samsung Plasma TV 5350 (not smart).
If you get a true Roku soundbar or streambar it has built-in roku streamer so won't need another roku. It can replace your express, and use the hdmi input its using on your tv. If the tv doesn't have hdmi-arc input, you'll have to use combination of hdmi input and optical output.
