Instead of the Chromecast Audio I got a Pi 4 and Startech 7.1 usb audio. With Pulseaudio you can remap channels, so I have 5.1 going to my old Yamaha (which lacks hdmi) and 2 channels going to a Denon that drives ceiling speakers in the adjoining kitchen. This handles movies, and has played everything up to Atmos, downmixed to 5.1. Also upmixes stereo to 5.1, sending <150Hz to the sub channel. It plays the same audio to both amps because it's open-plan, but the amps are separate so I can turn one down or off, or change to another source.
The Pi runs gmediarender-resurrect (a DLNA receiver) so I can fling audio from my laptop (pulseaudio-dlna) or phone (bubble upnp).
