Grouping Chromcast + Cast Audio

What is best practice to create media_player group to stream video to a Chromecast device and audio to one or more Google cast audio

I tried to create a group with all these devices and also to create a mediay_player join automation. But both things aren’t work (it I did everything right).

For example there are three devices:

  • media_player.chromecast
  • media_player.audio_left
  • media_player.audio_right

Any proposal?
