Lazyload not working for <audio> Tag

[kutec]

I tried to implement lazyload for <audio> tag and it's not working.

<audio controls>
    <source data-src="https://www.w3schools.com/html/horse.ogg" type="audio/ogg">
    <source data-src="https://www.w3schools.com/html/horse.mp3" type="audio/mpeg">
</audio>

Do I need additional configuration?

Thanks.
