Can anyone test what happens when you call media from these below urls to Google Cast using a group with Mini's AND a hub?
http://192.168.2.51:8123/local/path/mixdown.flac
https://ha.domain.com/local/path/mixdown.flac
target:
entity_id: media_player.alle_speakers
data:
media_content_id: media-source://media_source/local/audio/mixdown.flac
media_content_type: audio/flac```
And also what happens if you use the media picker and let it add media-source:// ? See above
