topics in ASP.net for project

I have a table called volume_issue that looks like this:

 +----+-------------------------------------------------------+-----------------+-----------+---------------------+
| id | url                                                   | journal_title   | issn      | volume_issue        |
+----+-------------------------------------------------------+-----------------+-----------+---------------------+

    $query = "SELECT  SUM(amount) FROM income_daily";
    $sum = mysqli_fetch_row(mysqli_query($con, $query));
     echo "Total Income : ". "¢" .$sum[0];

     echo '<br>';
    echo '-';
    echo '<br>';

     $query1 = "SELECT  SUM(amount) FROM expenses_daily";
    $sum ...

I need some help to add few audio effects to website.

I found some examples like following,

audioOn: true

audio.muted = false

setAudioOn true    

 ref: "audio",
    attrs: {
      "id": "projects-audio" ...
