So what I am attempting to set up is the following. I have a DAC2 Pro with the DSP addon module connected to a Pi 4 and running the HiFiBerry image. The interface shows in the system information that it recognizes the sound card being attached to the Pi. However, when I go to "Sources" I do not see the analogue inputs as a selectable source.
For comparison, I used a DSP DAC with the optical audio ports and was able to select the input and pass audio through the device.
The question at hand is - why am I not able to see the input ports on the sound card when the RaspPi can clearly detect the device?
