Get attachment thumbnail from get_posts function

Question

How do I get the id of the most recent wordpress audio media upload.
The reason for this is that I want to use audio cover images/ featured images as a post featured image.
Do I need to retrieve the ID of the thumbnail in the audio.

I tried the code below but it returned error

    $attachments = get_posts( array(
    'post_type' => 'attachment',
    'posts_per_page' => 1,
    'post_status' => null,
    'post_mime_type' => 'audio'
) );
    foreach ( $attachments as $attachment ) {
        $post_id = get_post_thumbnail_id( $attachment->ID);
    }
