    hi

    it seems address cannot be detected.

    have you change the tas5760 chip on the evm?

    you can take a measure to the pin12(SPK_SLEEP/ADR) to see how it behavior when power supply go up.

    also, you need to check these pins: 

    /SPK_SD, ANA_REG, GVDD_REG, AVDD, PVDD, GVDD.

    tks
