I have a Sonos surround sound system which is nice and convenient, but limited. It has a single input for digital audio. It's designed to take input directly from your TV. The problem is my TV only outputs surround sound for content it tunes or its built-in apps. So I've been using the really crappy Samsung Smart TV apps, but the selection sucks and it's laggy. I need to find me a TV that will output a 5.1 Dolby signal from its sources.
