surfninja I got this dac working using the hifi berry dac+ driver with my RP2. I bought it for my OpenElec instance but it works much better with RuneAudio.
technosf Dito with a Wingoneer PiFi Digi+ (it has SPDIF/TOSLINK), one of the many PCM5122 based PiHats. It's a HiFi Berry Digi+ to Rune. Works just fine.
