connecting to sonos bar on tv

Sonos does make an Arc soundbar. 

As previously pointed out, Sonos devices are not transmitters of Bluetooth, only receivers. You’d need to have the WiFi turned on on both devices, or have them both connected back to your router with an Ethernet cable to group them. There will still be a 75ms delay between the Arc any any ‘grouped’ room. However, if a pair of speakers is set up as surrounds, and ‘bonded’ to the Arc, there is no delay, but the surround speakers will carry the surround channels, and not the front channels.
