I'm trying to see if I can add a digital audio input to my RPI using the hifiberry digi+? If so, can it input and output digital audio at the same time? I want to bring digital audio in, do some DSP in the raspberry pi, then send digital audio out.
Second question: does the digi or any of the other rpi audio products output in balanced digital (AES/EBU)? I'm currently using a transformer to go from single-ended (SPDIF) to balanced digital (AES), it would be convenient to not need the transformer.
