    Hi Li,

    Can you please elaborate on the the issue? 

    1.) Are the output PWM's switching?

    2.) Are the I2S inputs present and look okay? What are the clock frequencies?

    3.) Are the terminal pins (MUTE, PDN, RESET) all high? and are the format pins set to the correct configuration?

    4.) What are the voltages on the supply pins (PVDD, AVDD, DVDD, AVCC) & also on the BST, VCLAMP pins?
