No Sound in Windows 8 apps like XBOX Music or Video applications

No Sound in Windows 8 apps

The reason behind this is some specific Windows Store app that may be using JavaScript. Such an app is similar to an app for Internet Explorer or for any HTML5-compatible browser, and may typically consists of components, documents, resources and behaviors developed by using the following technologies:
  • HTML (HTML5)
  • CSS (CSS3)
  • JavaScript (ECMAScript)
The process that hosts and executes a Windows Store app using JavaScript is called WWAHost.exe. This process provides a superset of functionality greater than that provided by the Microsoft Internet Explorer browser, says Microsoft. Therefore, if your web app runs under Internet Explorer, it can also easily be run under WWAHost.exe.

So if you find that sound is disabled in webpages which are HTML based, CSS based or Java-script based, none of the Windows 8 Store application that are ported from web-based application will have sound. To fix this we need to check and make sure “Play sound in Webpage” is enabled in the Internet Explorer.

Enable sound in Internet Explorer

To enable sound in Internet Explorer follow these:
  • Open Internet Explorer (Desktop version)
  • Go to Settings and click on Internet Options
  • Under Internet Options click on Advance Tab
  • Under settings section scroll down and find Multimedia section
  • There, make sure you enable all the check boxes except “Show image downloaded placeholders”
  • Click on apply and click OK
  • Now you may need to reboot the system.
Now most of the Windows Store applications should be working fine.
