I'm considering getting a Philips Smart TV which I need to connect to my existing soundbar. I don't want to use cables for the sound connection, so I'm thinking about using some kind of Airport Extreme bridge (my soundbar has SPDIF connections, but no Airplay).

So the question is: can I use Airplay technology to send wirelessly sound from a Philips Smart TV (whichever model) to a soundbar, using something like Airplay on both sides? Can Smart TV act as Airplay senders?

Other routes would be using a wirelles sender-receiver to convert the audio digital out from the TV to the audio digital in from the soundbar, sure...
