Do you know how to access the browser source settings menu of the display in question? I know there is a chrome browser on board.
I would like to authorize the automatic playback of sounds on a web page without user interaction
For Signage questions you should go to the B2B Portal and there is a community there.
I would assume that the browser is based on Chromium, like Chrome that is what Samsung Internet is based on.
