Music Assistant fails to stream anywhere

[Gekko23]

I'm new to Home Assistant and have an issue with Music Assistant: The player does not stream anywhere to. I selected 'Home Asssistant' as a plugin provider first. After that i defined 'Home Assistant' as a provider of a 'player'.

After that, i defined two destinations inside the Home Assistant 'player' for media playback: an AppleTV and a Smart-TV:

When i now start a song while i use one or both of the destinations, nothing happens. I can change the volume with the devices giving feedback that they changed their volume, too. But the song will not start, no transport indicator is showing up, no time starts running:

The destination with a closer look - song doesn't play:

This is what the logs looks like:

What am i doing wrong? Please be kind, i'm using Home Assistant just for 3 days, so i'm a bloody newbie. But i didn't find any clue for this behavior anywhere.

Thanks for hints and tips!

Oh...i forgot to mention: If i start the song using Music Assistant in a webbrowser with the webrowser as playback destination, the song plays flawlessly!

What provider are you using to playback to the web browser?
