Trying to update the title of the playlist playing when playing other files besides the default one. A video should be instructive. Note, the URL is behind a password, ilovenews.

Thanks!

it is a bit of a custom implementation, but essentially just a gutenberg block.

add_action( 'newspack_theme_entry_meta', function () {

    if ( ! has_block( 'core/audio' ) ) {
        return;
    }

    $block = '';
    $post = get_post()->post_content;

    $first_block = parse_blocks( $post )[0];

    $isFirstBlockAudioPlayer = $first_block['blockName'] === 'core/audio';

    if ( $isFirstBlockAudioPlayer ) {
        $audio_url =  wp_get_attachment_url( $first_block['attrs']['id'] );
        $block .= do_blocks( '<!-- wp:sonaar/sonaar-block {"player_layout":"skin_button","show_volume_bt":"false","show_speed_bt":"false","show_shuffle_bt":"false","show_tracks_count":"false","show_meta_duration":"false","show_publish_date":"false","show_skip_bt":"false","playlist_show_playlist":false,"playlist_show_album_market":false,"playlist_hide_artwork":true,"notrackskip":true,"button_align":"flex-start","hide_player_subheading":true,"audio_player_play_text_color":"#000000","audio_player_play_text_color_hover":"#ffffff","hide_player_title":true,"player_inline":true,"soundwave_show":true,"use_play_label":true,"audio_player_controls_color":"#ffffff","audio_player_controls_color_hover":"#000000","play_text":"Listen","shortcode_parameters":"feed=\u0022' . esc_url( $audio_url )  .
