Loop 5 second alarm sound and stop when disarmed

Configuration
1

I have been trying to build a loop for most of the afternoon, but seeing some strange behaviour. This is the code atm (without a loop yet)

- alias: 'Manual - Alarm triggered'                                                                                                   
  trigger:
    - platform: state
      entity_id: alarm_control_panel.home_alarm
      to: triggered

  action:
    - service: notify.mobile_app_xxxx
      data_template:
        title: 'Alarm'
        message: >
            Alarm triggered - Siren
        data:
          push:
            sound: "sirene.wav"

    - service: media_player.volume_set
      data_template:
        entity_id:
        - media_player.keuken
        - media_player.woonkamer
        volume_level: 0.1

    - service: media_player.play_media
      data:
        media_content_id: http://x.x.x.x:123/local/sirene.mp3
        media_content_type: music
      target:
        entity_id:
        - media_player.keuken
        - media_player.woonkamer

It plays the 5 second sound once for media_player.keuken but loops for media_player.woonkamer. Anyone got an idea why that might be?

Also trying to stop it playing when disarming does not work. It just does not stop playing.

- alias: 'Manual - Alarm disarmed'                                                                                                   
  trigger:
    - platform: state
      entity_id: alarm_control_panel.home_alarm
      to: disarmed

  action:
    - service: notify.mobile_app_xxx
      data_template:
        title: 'Alarm'
        message: >
            Alarm disarmed
            
    - service: media_player.media_stop
      data:
      entity_id: 
        - media_player.woonkamer
        - media_player.keuken
