How can I add a sound to a lightning button in LWC?

import { LightningElement } from 'lwc';
const audio = new Audio("https://www.fesliyanstudios.com/play-mp3/387");

export default class GetRandomQuotes extends LightningElement {
    sound = audio;

What you're likely experiencing is a limitation imposed by Salesforce CSP. In order to make it work, you need to Manage CSP Trusted Sites. Go to Setup | CSP Trusted Sites, and add the site to enable access to the media files. Outside of Salesforce, LWC has no problem loading and playing the click sound.
