Eventually I have been able to get the runeaudio UI to work on the Pi. I can change audio ouput between 3.5 jack on the pi and the hifiberry. However, there is no sound from the DAC only from the Pi jack. How do I know if I have a duff DAC. the Rune debug log states hifiberry but not sure if that is code or from result of the OS detecting the DAC.
