ADAU1787 EVB I2S in & out non-reasonable
Hi ADI, I recently used ADAU1787 EVB and found some weird. When I ues I2S function which pin are SAI, I didn't give any input to AIN0 &1, even AIN0 &1+ tie to ground should have nothing at I2S ouput.

EVAL-ADAU1452 - distortion on i2s inputs
Hi there, I have an external i2s source which I connected to my logic analyser to confirm a solid digital signal: It shows a 3MHz SCLK, 48kHz LRCLK and the i2s analyser gets good 24-bit data values. I
