Looking at these lines, it seems a permalink related setting might help me out:
// Audio file
$audio_file = $ss_podcasting->get_enclosure( get_the_ID() );
if ( get_option( 'permalink_structure' ) ) {
$enclosure = $ss_podcasting->get_episode_download_link( get_the_ID() );
} else {
$enclosure = $audio_file;
}
Let’s find out ??
