  • Forum Post: BIOSPSP audio example for C674x

    Yan8622
    Hi, The audio example given in the C674x BIOSPSP package would stop running if the audio processing between SIO Rx and Tx takes too long. I think a better handling of this situation would be to skip the a few audio frames but without breaking anything. Any advice how to do that? Thanks
