Developer tools successfully submits this YAML to send a radio stream to the receiver, but nothing plays on my Denon X1200W receiver:
action: media_player.play_media
data:
media_content_id: media-source://radio_browser/799cef6d-51d7-435a-b973-1a469cc05513
media_content_type: music
target:
device_id: 5213f6bc1f06b3d0d0a482667613302c
The log shows:
2025-01-22 22:00:41.530 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [547291177760] Entity media_player.denon_avr_x1200w does not support action media_player.play_media
But it is a DLNA media player and does play MP3, AAC, FLAC, so am I misunderstanding how to specify the content-id? Using this same content-id I can play the stream to a Sonos One successfully, just not to the Denon AVR. I also tried https://streaming.live365.com/a49833 (a known MP3 stream), which also works as the content-id for the Sonos.
