    Files not accepted?

    Hi all,

    I'm working on my first Teensy 3.2 with audio shield and so far I really love it, so thanks!
    However, I do have some issues on loading my own WAV files instead of the public available test files.

    I did do some searching in finding any content-requirements/limitations, but couldn't find a page describing this.

    At this moment, when loading my own files the device won't play the sound.
    The thing that is really different as the sample files is filesize and track length

    My track is around 100Mb and has a length of 7 minutes.
    (track length is not final, but will stay below 10 minutes)
    I named it the same as the sample file("SDTEST1.wav")

    I put the files in MediaInfo to see if I could find difference, the only difference I noted was the bitrate and the sampling rate.
    Is there anyone on the forum who can tell me how to make this work?

    Here are the MediaInfo results (left the Complete Name blank due to privacy reasons):

    without changes, the Teensy audio system is working with 44.1 kHz and not 48 kHz sampling
