As was mentioned, a TV can be connected to both using HDMI ARC/eARC for soundbar and optical to another device. But, the audio output will need to be set manually on many new TVs in an either/or scenario. I'd go the two speakers with powered sub hooked up to the Fosi and placed accordingly here and forget the soundbar. The Fosi only supports PCM signals so the TV's optical port will need to be set for PCM output as Dolby and DTS signals will not work and will produce no sound or, worse, loud noise when played.
