im just wondering where these AUX-inputs came from? i found this in one of the example profiles named 4way-iir-delay-mixer.
there are the normal inputs from the Pi and SPDIF but also Inputs 16+17 and 40+41
so how is this possible? are they using the add-on board for analogue inputs/outputs? im really interested in how they do this.
i can not understand why such great products were not documented and supported well. almost nobody know what is even possible with these boards and for adding a little thing like external volume control you waste hours of searching the internet.
