Universal Media Player - Source List

Hello,

I’m trying to set up Universal Media Player (Universal Media Player - Home Assistant) with a bunch of Chromecasts and Google home speaker groups as sources. I have just started working with home assistant so I’m still learning exactly how things work.
this is what I have so far added into my configuration.yaml

media_player:
  - platform: universal
    name: All Devices
    children:
        - media_player.all_speakers
        - media_player.living_room
        - media_player.office
        - media_player.surround_sound
        - media_player.upstairs_speakers

This works, and will display the item that’s actively playing something that highest on the list. But it doesn’t show the name of the source and there is no way to change between them.

I’m assuming i need to do something with source_list and select_source but i don’t really know what

Any help would be appreciated.
