autoplay audio

Im new atthis sorta stuff. well i did this 20 + years ago, and lets just say my memory isn't what it used to be. I can't seem to get my audio to autoplay. I've seen where ya'll say I need to add a code block tnen add the code for the music etc. I'm not sure what you mean by code block. nobody ever mentions how to codeblock. can someone help a old mimi out ? i would be so ever grateful. i just need a memory jolt then i wouldnt bother yall. thank you in advance!!!😶‍🌫️

What is your site url?
