For watching movies I’m using my ATV to send audio via airplay to utilize my whole house audio (ceiling) speakers and a subwoofer that are hooked up to centralized system (amplifiers are downstairs). I need a local soundbar to fill in a dead spot and if my ATV could output sound via optical or HDMI to use either a soundbar or my tv speakers simultaneously I would be all dialed in. Is it possible to do this with an ATV?
