PCM9211: eARC Questions

Part Number:PCM9211

Hi, Team,

A customer considers to use PCM9211 as eARC receiver. I have a basic questions.

- Do we need software to control PCM9211?
- Do you have the sample code for PCM9211?
- Is there a reference schematic of PCM9211 eARC configuration?

Best Regards,
