I need to make a raspberry when i plug the power supply auto start play music from folder or usb etc. But carefull! i need this for a car audio project so in my project DOESNT exist external display or mouse-keyboard etc so i need only plug and play if is possible. As i say and before im new to this world so i need step by step.. ex. What software must use, (now im using openelec), how to setup, etc..
My raspberry is Raspberry pi 3 model b
Thanks in advance
