I was looking a way to do it, but found a lot of question regarding this on forum but no real solution. Hope someone write a plugin.
Need to clear queue, auto open and play a user Playlist on each startup.
I found a temporary solution, it’s not too good but at least works.
If to make ‘queue’ file readonly via ssh (sudo chmod 444 queue) then it will load each time on startup even if cleared or changed by user later via web interface. Hope someone find useful.
And then it’s necessary to install and enable autoplay plugin
