Currently testing this on an older Pi 2 model B. I have the DAC+ADC connected but I'm getting no sound when connecting via aux 3.5mm from Hifiberry to my speakers (powered). I've tried this with both new installs of HifiberryOS and Volumio with same results.
Is the 3.5mm for input only? or am I limited by the older Pi i'm using? I have a model 3 I can test with but was hoping to use the oldest one for this project.
