I’ve installed Volumio on my RPi3, and installed the Squeezelite plugin, and it works really well, except that it doesn’t restart when I restart Volumio, so I have to login in, disable and re-enable it… then it works fine again.
I assume it’s not been registered in some form of login script - I’m happy and able to do this (I can drive putty etc) if someone could tell me what to do.
