I am using the DSP Add-on board and I have noticed that there is a SPDIF ipnut pin on one of the extension headers. I would like to use this as input source and do some crossover (so the 4way profile would be ideal). Can I use one of the example DSP profiles provided in the github repo? I found that some profiles have a 'channelSelectRegister'. Do I change the input source with this parameter? If so, how?
Are there some detailed descriptions of the sample profiles and their parameters?
