>>How should i progress?

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
