Smart Home Audio

Cool post. 

To answer your question, yes smart home audio systems exist. 

Sonos in ceiling speakers are probably your best option. Many folks I know who live in really big houses love their Sonos T.V. sound bars. They are very popular and can be configured quite easily. 

I once visited a relative who had some Sonos speakers in her kitchen. Wall mounted, so she controlled it with a Sonos amp and to be honest it sounded amazing for such a small set.

I know exactly where they can program any thing in your house. Sirin software can do this. They were advised to me on other forums and I am satisfied with the results of my project. You can get acquainted with their services in detail by the link  https://sirinsoftware.com/services/

It's great that you wrote a post like this. I too am interested in this topic. I've only found individual systems, but not in their entirety. Soundbars don't always connect correctly, and it's a horror of sorts.
