Form auto submit no longer working

I have an auto submit on some forms where audio is playing, it’s simple code and it’s worked for months, but since the update isn’t working. I’d appreciate any help!

Here is the code:

> <h2 id="heading" style="display:block; text-align:center;"><a onclick="playAudio()"><u>Volume Up - Click Me</u></a></h2>
> 
> <audio id="audio">
>   <source src="https://moebiusinc.com/wp-content/uploads/2021/04/mixdown-1.mp3"  type="audio/mpeg">
> Your browser does not support the audio element.
> </audio>
> 
> <script>
> 
> var audioStore = document.getElementById("audio");
> 
> function playAudio() { 
>  audioStore.volume = 0.5;
>  audioStore.play(); 
> } 
> 
> document.querySelector('audio').addEventListener('ended',function()
> {
> jQuery( 'form#gform_1' ).trigger( 'submit' );
>   }, false);
> </script>

Many thanks in advance

Update on this, i’ve had to downgraded my version of Gravity Forms and it’s now working, so it’s definitely the new update that has broken the functionality.

Anyone have any idea why?
