The project consists of Tonio daemon software, implementing Jukebox functionality, and a set of carefully crafted Buildroot external configurations for selected boards.
Still, you may want to build the root image yourself. Supporting a new board or adding more codecs than the default are all good reasons for doing so.
Nope. But you can create tickets for the wider audience or fix issues yourself and contribute. Sure enough, you can also say thanks and show your Tonio at work!
You're wellcome. Pull requests are the way to go. Just in case you're out of ideas look at the board for version One dot Zero at https://github.com/comick/tonio/projects/2.
