I am trying to set up the ADAU1781 as an audio codec for the Pi 3 B, communicating with the Pi via the GPIO pins. Which pins would I use for I2S audio input and output? I have been doing a lot of research on the subject and cannot seem to find a clear answer to the question. Would it be the TXD0 and RXD0 or is it one of the GPIO_GEN pins as set up by the driver?
