When I built a new house a few years ago I planned to buy some chrome audio devices and amps to power my ceiling speakers. Alas, chrome audio devices were discontinued and I ended up using a combination of regular chromes, hdmi to tv convertors and Aiyima A07 amps. This worked OK but volume control required access to the amp volume control knob.
I've been watching for all in one solution, other than Sonos, which doesn't have a multiple user feature compatible with Google Home. This all changed recently with the release of the WiiM Amp which is a 60W per channel stereo amp with built in Chrome, among other apps. Check it out.

This thing is great and only $299. I bought one a few weeks ago and am totally impressed. So nice to have volume control!
BTW I have no affiliation with Wiim.
