prometh wrotehow about the 2+ Version which uses a PCM5102A DAC, does this one work already?
That's the DAC used in HiFiBerry DAC+, IQaudIO Pi-DAC+ and RaspyPlay4, so it's worth to try to select one of them from the I²S kernel modules select menu in the Settings screen, and see if it works out of the box. If you have the possibility to test it please report the results here.
