I added an Amp today and connected my turntable to it. The set-up was quite confusing and a new room was created (TV Room 2) in the process.
The turntable only works if the TV is on.
Desired End Goal:
One room called TV Room. All Speakers and Amp paired and Line In to Amp does not require TV to be on.

The Amp also has the possibility to use passive speakers as surrounds together with the Playbase. The Amp will then become bonded to your playbase in the 5.1 setup and you would be able to re-purpose your Sonos One surrounds in 1 or 2 other rooms.
As you can see, Sonos offers many possibilities and configurations, but unfortunately sales reps are often not very well versed in what it can and cannot do and are just looking to sell. You are not the first person to start a topic on this community, having been sold or told things that are not possible, or in your case, having been sold a very expensive sledgehammer to crack a very simple nut.
