A quick look does not find such a feature. However it appears to have optical audio out which would go to your sound system and from there to other things.
Beware that multi-room can create a delay that you hear at stadiums and any networking could induce even more delay. Stay wired?
I want to stream(wirelessly) TV audio to my receiver/amp that controls multi-room wired speakers. Can a Samsung smart tv (e.g. UN65F7100) do this with its wireless capability? If not how can I do this?
