As in the title I was going to use Volumio 1.55, run a rpi-update before to plug DAC+ on the Pi but now the Pi doesn't boot and it's showing only the splash/rainbow screen.
Everything works ok without the DAC, everything was working fine with Volumio 1.5b before the rpi-update.
Any hints? Thanks!
B+ and DAC doesn't boot after rpi-update
