    Hello, and welcome to E2E!

    This is a good question, the device is capable of detecting the type of jack (3-pole, 4-pole standard, or 4-pole OMTP) using the I2C digital interface. This table, taken from the Register Field Descriptions section of the datasheet, shows that the status of the 0Bh register will indicate the type of jack inserted.

    Let me know if this helps!

    Best regards,
    Kate
