Just figured out my own question. Navigate to the Line-in option at the top level of browse. Using the tv hdmi ‘in’, music storage Ethernet ‘in’, and a karaoke fifine box rca ‘in’. The audio auto-switches well enough from tv and music, but can’t get the rca audio to work. Figured it out.

You have to manual choose the rca in from the browse menu in Sonos app - at the very bottom Line In …. auto-switch doesn't work with the RCA on the new Sonos Amp.
