Abnormal output of AD5112



My customer is using AD5112 in wireless audio volume control project,they had run pp test and find that When they had control AD5112 with MCU by I2C,output side with A or W pin will have level of change, then it had audio volume's variety, but the output has noise, refer to the detailed wave from the snap picture attached. We had suggested it slow down speed With I2C clock, but it doesn't work.

Would you please share any suggestion for this technical issue?
