TAS2557EVM: no sound output during playing specific song

Part Number: TAS2557EVM

Hello,

In general, it works fine, but found the output will drop sometimes and not recoverable by playing specific song. 

- it always stopped at the same point

- by reducing the volume, the stopped point changed

- it's not related to playing order, e.g. to play 10 songs, always this song has problem

And after, no sound from the speaker and need to power cycle to recover. The I2S interface is ok, the player keeps playing. 

What might cause this and how to fix?

  • Hi, Christy,

    Thank you for the details you provided. Our team will take a look at this and will come back as soon as possible.

    In the meantime, could you provide the registers configuration or PPC3 settings? Do you also have details about the power supplies and jumpers placement you are using?

    Thank you.

    Best regards,
    Luis Fernando Rodríguez S.

  • Hi Christy,

    Could you please read registers 0x68 and 0x6C from book 0 page 0 after the audio stops? I want to check if there is any flag being triggered.

    Are you using the EVM or a custom board? If using a custom board, can you please share your schematic?

    Best regards,

  • Thanks, Ivan.

    It happened at out board, and we fixed this issue, it's from input power, The analog block register was set to down, 00 when it happens.
