def play_one_audio_file(local_audio_file):
    '''
    Play a local audio file using soundfile and sounddevice.

    Parameters
    ----------
    local_audio_file : string
        Local location to the audio file to be played. When it is a directory,
        a file will be randomly chosen.

    Returns
    -------
    None

    Raises
    ------
    DLPyError
        If anything goes wrong, it complains and prints the appropriate message.
