I would like to suggest the development of a new component that allows you to play live streaming audio.
Unfortunately the Browser and HTML components do not work with HTML players that contain the "Autoplay" function. This makes it impossible to broadcast live radio on any device with the Signage Player.
The autal component of "Radio" is just a Playlist, and does not have advanced features for broadcasting an external live radio.
This sounds like something very simple to develop since there are many streaming players available on the internet that work perfectly in any browser, but in Signage Studio components this is not possible.
