After communicating with CS FAE, the same issue was also tested on the CS43198 development board. FAE found some information about the non-oversampling filters which is NOS native, without oversampling, with authentic sound and more high-frequency spikes. The pop sound can be heard with high-sensitivity headphones.

This is a characteristic of the CS43198 filter. We have attempted to optimize it but were ultimately unsuccessful. We hope you can understand.
