I assume the ** were an attempt to show the code here and are not part of the code you embed.
I’m not familiar with jwplayer I’m afraid, looking at their documentation - https://support.jwplayer.com/articles/how-to-autostart-on-page-load https://support.jwplayer.com/articles/how-to-embed-an-hls-stream
there does not seem to be much more than autostart: true, but perhaps there is something missing, I’ve never used that.
The autostart or in this case even the playback will highly depend on the Android version of your device, it might also be the case (same as with YouTube autoplay) that it is not working on all android devices.
Regarding the HLS itself, if you’re running 1.8 series CMS and player and your android is using at least Android 6 you can use the direct HLS URL in HLS module in Xibo.
For android devices running earlier Android version, you might be able to play that via localVideo module instead.
