    Hi, Sonmook,

    I am not familiar with the TMD part, but the  question about the data handling would be better addressed if you ask for it in the Processors Forum. We can help you with the codec configuration questions.

    Hi SonMook,

    To add to what Diego said, you need to make sure that the Processor and Codec are programmed for the same Serial data.

    so if the codec is setup for 48k 32bit, in I2S mode, then the processor must also be setup for that, otherwise you have two different devices communicating in different modes, and you get garbage.

    The AIC3106 is easily set up for 48k, 32bit, I2S mode. please let me know if you need help with the codec settings. As diego said, that's as much as we can offer in the audio forum, for help with McASP setup, you can go to the processors forum.

    best regards,
