TAS5414C: no output

Part Number: TAS5414C

Hi 

The customer can capture the I2C Address, but after passing the front-end codec output to the tas5414c input, the tas5414c also does not output sound, but it is confirmed that the codec output has sound output.

Do I need to do other initialization settings after the I2C is powered on?

    Hi Gareth,

    It appears that the device is in HI-Z mode.  This is the default mode when it is powered up.  Change register 0x0C to 0x00 to turn the channels on and unmute them.  A thorough read of the datasheet for Load Diagnostics and protection with also help undestanding this device.

    Regards,
    Gregg Scott
