Yes, you need an audio source. What I would recommend is getting a SONOS Connect that way you plug into that and then the rest of the speakers would receive the audio signal from the Connect. The Connect is very small and easy to hide, you might even be able to figure out a way to hide it behind the tv. The only way you could get Zero wired would be for Sony to have a Bluetooth connection option and SONOS would have to set it up to where the speakers could connect through Bluetooth, but I do not think that will happen.

Sorry, there was a problem. Please try again later.A wireless system can be achieved using Sonos. The Sonos system allows you to install a complete surroundsound system without any wires to the speakers. The base is exceptional and the sound is exceptional. It is well worth the cost and investment. The system I have installed allows me to have a full surroundsound system in the greatroom, stereo sound on the patio, stereo sound in master bedroom, stereo sound in garage, and stereo sound in guest suite. This was achieved without the installation of any speaker wires. Contact your Sonos dealer to resolve your issue.
