Chromecast support

[eniriop]

I’ve been keen to do this for awhile to better control Spotify Connect with voice commands.  Are there many alternatives or hacked together workarounds.  I’ve tried connecting a Google Home Mini to the Phantoms by Bluetooth and setting as default speaker but the connection drops after a while of non-use. Could connect a chrome cast audio via optical to the Phantoms, but their optical auto switch doesn’t recognise the chrome cast turning on (at least doesn’t work for me but auto switch has always been flakey for me. Any other ideas?  Or tips to get optical auto switch working?

The optical auto switch is turned on only when you play a file through the optical wire plugged to one of the phantom (for example when you turn on the TV if the optical wire is connected to the TV audio out).
