Hi @rudtek

You need to get the post title for the order sort. It should be something like this:

function my_acf_sort_post_object( $value, $post_id, $field ) {
	
	// vars
	$order = array();
	
	// bail early if no value
	if( empty($value) ) {
		return $value;	
	}
	
	// populate order
	foreach( $value as $i => $post_id ) {
        $post_title = get_the_title($post_id);
		$order[ $i ] = $post_title;
	}
    
    $order_lowercase = array_map('strtolower', $order);
	
	// multisort
	array_multisort( $order_lowercase, SORT_ASC, SORT_STRING, $value );
	
	// return	
	return $value;	
}

add_filter('acf/load_value/name=session_speaker', 'my_acf_sort_post_object', 10, 3);

Could you please test it out?

I hope this helps 🙂
