Find other examples, and port to your platform. Read/Review the documentation for the IC

    "I2C only" - for control hopefully?

    Or does it accept audio data via I2C? Which is very unusual, so you hopefully mean to transmit audio data via I2S ?

    Anyway, as TDL said: RTFM ;)

      As the others have suggested, the datasheet will answer that; eg:

      You can see that the I2C is not in the audio path

       

      A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.
