Hello
@Shablbl ,
Refer
the link and use it in Rich content Editor -> source(<>) of question
To autoplay you can use below code:
`<embed src="source url" type="audio/*" width="180" height="90" loop="false" autostart="true" hidden="true" />`
To play audio after your chronometer(what chronometer are you using?) then add following line to the chronometer end event in the js of question (if yor are using audio tag to play audio not embed tag)
` jQuery("audio").play();`
