Setup: 2 channel ADC set up as master into ADAU1446, as slave.
I'm having a slight problem in that I am getting full range noise (white noise/hiss) on one channel of my ADC, only when a signal is present. If I invert the polarity of the LR clock in sigmastudio the noise moves to the other channel on the converter. Clock signals look ok.
Has anyone got any suggestions on what this could be or where to look please.
