Why doesn't sonos turn on?

hi guys, can you see if something here is wrong, everything here happens except that sonos doesn’t turn on?

  • action:
    • alias: Info LARM OFF
      data:
      message: AV
      title: LARM
      service: notify.ios_marcus_iphone7
    • alias: Info LARM OFF

      message: AV

      service: notify.ios_hedvigs_iphone
    • alias: Sonos_on
      data:
      entity_id: media_player.vardagsrum
      volume_level: 0.15
      service: media_player.media_play
      alias: Info LARM OFF
      condition: []
      id: ‘1510506379404’
      trigger:
    • entity_id: switch.larm
      from: ‘on’
      platform: state
      to: ‘off’

Can you mark your YAML with the </> button (Preformatted text) please - as explained in the large blue box at the top.

As Tinkerer says, it’s hard to spot any other errors because of the formatting, but

service: media_player.media_play should be service: media_player.play_media

And I think you also haven’t specified which media to actually play.

perfect - now it works
