It doesn't work like that, and there's no simple way to do what you're proposing in real time.
1-You'll need to output your analog source into an ADC, connected to a PC. A USB audio interface is the best.
2-Install this onto the PC with a USB audio interface https://github.com/SamDel/ChromeCast-Desktop-Audio-Streamer/releases
3-Setup the CCA on the system that you want to play.
4-From the PC with the USB audio interface, Connect it to the CCA upstairs with Chromecast desktop audio streamer.
5-From the PC with the USB audio interface, in sound properties in control panel, set it to "listen" to the USB audio interface, make sure analog source is playing.
There will be around a 8-10 second delay
Installed the latest release and windows installer but windows will not let it run. hmmmm
