Howto get Denon HEOS status

Configuration
1

Hi,

I would like to check the status (play, stopped) of my Denon HEOS loudspeakers. What is wrong in my YAML?

  - if:
      - condition: state
        entity_id: media_player.wohnzimmer_links
        state: playing
    then:
        ....

Many thanks for all your hints!
Christof
