Tool/software:
We use this IC:TLV320AIC3101, when the motherboard is powered on, the I2C SDA line keeps being pulled low and can't be boosted to 3.3v. It can only be restored to normal after the chip has been reset.

Hi Zhang,
Double check that you are following the power sequence recommendation from the datasheet, especially keeping RESET low until all power supplies are stable.
Best regards,
