How can I play a sound as part of a triggered function

Question

I am trying to build a type of alarm clock with a Google sheet. Can anyone think of a way I can play a sound on a trigger?

Until the release of IFRAME sandboxes in December 2014 (and the subsequent months of bug fixes ;) it was not possible to support HTML5 audio tags through Google Apps Script's Caja-sanitized HTML. See issue 2196.

Here's a simple example that embeds a music player into a document sidebar.

Code.gs

var SIDEBAR_TITLE = 'Sidebar Musicbox';

/**
 * Adds a custom menu with items to show the sidebar and dialog.
 *
 * @param {Object} e The event parameter for a simple onOpen trigger.
 */
function onOpen(e) {
  DocumentApp.getUi()
      .createAddonMenu()
      .addItem('Show sidebar', 'showSidebar')
      .addToUi();
}

/**
 * Runs when the add-on is installed; calls onOpen() to ensure menu creation and
 * any other initializion work is done immediately.
 *
 * @param {Object} e The event parameter for a simple onInstall trigger.
 */
function onInstall(e) {
  onOpen(e);
}

/**
 * Opens a sidebar. The sidebar structure is described in the Sidebar.html
 * project file.
 */
function showSidebar() {
  var ui = HtmlService.createTemplateFromFile('Sidebar')
      .evaluate()
      .setSandboxMode(HtmlService.SandboxMode.IFRAME)
      .setTitle(SIDEBAR_TITLE);
  DocumentApp.getUi().showSidebar(ui);
}
