ADAU1761 pops at power switch
There is a problem with our use of ADAU1761, which is detailed as follows：
There was a relatively obvious POP sound in the system during power-on and power-off. After investigation, it was found that the amplitude of differential signal was inconsistent during power-on and power-off of AUDAU1761, resulting in the output of differential mode signal to the speaker。

Hello sunyun,,
This can be minimized by increasing the size of the common mode filter cap and the output series capacitors but it will not fully go away. My suggestion is that an external muting circuit be used to mute the output while the power supplies and codec all stabilize.
