Chromecast 4k not as audio device for routine

[Mar14]

Hi all, I would like to play a Spotify playlist when I come back home with a routine.

I have a chromecast 4k connected to my tv and I added it to a home group.

When I enter my home, I am able to turn on the tv but not to play anything. A message in the routine warns "No device for audio available ".

I searched on web a possible solution but everything refer to chromecast audio.

Is there a solution? Which is my mistake?

Thanks in advance
