Universal Media Player - need help!

Need help with configuration of Universal Media Player. I can’t get source working as I want. If there is only media_player.orange|source its have attribute “source”. Maybe some1 could help me out to make it working well.

media_player:
  - platform: universal
    name: Kino domowe
    device_class: tv
    toggle_power: false
    children: 
    - media_player.plex_plex_cast_chromecast_5
    - media_player.plex_plex_for_android_tv_bravia_4k_vh2_2
    - media_player.orange
    - media_player.salon_tv
    # - media_player.android_tv_192_168_1_74
    commands:
      media_next_channel:
       service: media_player.media_next_track
       data: {}
       target:
         entity_id: media_player.livebox
      media_previous_track:
       service: media_player.media_previous_track
       data: {}
       target:
         entity_id: media_player.livebox
      select_source:
        service: script.turn_on
        data: {}
