Guys, I have a question regarding the sample rate. We are using ADAU1401 as a crossover. The problem is in external MCLK as we use different audio sources with different sample rates. So the crossover's characteristics will changed when incoming sample rate changes. How to fix this issue without adding an external MCU? In case if we use an MCU can we simply connect it to a I2C line and control the internal sample rate settings? How to control it?
