Core Linkplay Integration

In my case, media_player.join throws no errors and appears to group the speakers. However, in reality, nothing happens. The speakers are still independant, the native app shows no grouping and Home Assistant no longer sees them. They all just become “unavailable”.

…Are You Shpongled? :wink:

I hope I’m in the right place!?!

Since LinkPlay was integrated into HA, the media player does not provide the “media_content_id” attribute. Why?
