Dietpi with Soekris DAC

Has anybody tried the driver for the Soekris DAM 1021? I cannot get any signal through to the dac from the Pi. I have installed Roon, and in the audio I have picked the Soekris Dac. There is a LED on the Soekris that lights up when it locks. It works fine with a USB2DAC board, but no luck with the Pi. Any ideas?

got it working :slight_smile:
