We have a board with one ADAU1442 and one ADAU1966 in TDM16 mode. As soon as we upload a SigmaStudio file with some processing, one output drops samples (probably almost output 1, 2, 3 or 4). You can easily see what goes wrong when we insert a sine generator of 4 kHz on channel 2 in this case. I've included the SigmaStudio file for reference. Any ideas?
