How can I use "media_content_type: Audio Player"

[Tidabblju]

For listening internet radio I'm using TuneIn Radio. It's working well with Alexa Media Player in Homeassistant.
But, I get a lot of advertisement. When using the same radio station in "Audio Player", I don't get this ad's. Is it possible to use "Audio Player" as source? I already use "audio player" or "audio_player" as "media_content_type" but it doesn't work.
