Hi Zhanpeng,

What kind of pop is heard?

Is it startup pop, power down pop or AC-off pop?

Actions below will help to narrow down this issue:

To measure the pop waveform with PDN;
To check whether sequence (startup/power down) on page 43 of ds are followed or not? Captures are needed for analysis;
To share the I2C initialization header file for the check;
To measure the DC offset value in idle mode (PWM switches but no input music)

BR,
