PCM5100A: Audio Line Out Issue/Headphone Pop Noise

Part Number: PCM5100A


Hi team,

When the power is turned on, there will be pop noise appearing in line out. We have used XSMT mute for about 7-8 seconds as below figure.

However, when I2S_CLK has a signal, it will hear a very obvious pop sound. Now it is -22dB, which is much worse than the specification -60dB.

Would you have suggestion to improve it?
