Hello!
The snippet cited by lingthusiast worked for me, however, only on desktop and not in AnkiDroid. What made it work on both platorms was
<script>
var elem = document.querySelector(".soundLink, .replaybutton");
if (elem) {
elem.click();
}else{
window.onload = function(){
var elem = document.querySelector(".soundLink, .replaybutton");
if (elem) { elem.click();}
}
}
</script>
but then I had to disable automatic playback of audio fields for the deck in AnkiDroid.
