I’m assuming you mean a PLAY:5 Gen 2, as so far, there is only one version of the Sonos Five. 

The PLAY:5 series of speakers isn’t designed as TV speakers, unlike the Beam, PLAYBASE and Arc, but you could conceivably take an analog output from your TV and connect it to the Line In on the PLAY:5. Unfortunately, any analog line in on a Sonos would incur a minimum delay of around 75ms, so lipsync would be problematic with the TV.

You would be much better off getting one of Sonos’ sound bars to use with your TV.
