WAV files require a browser "Plugin" to play correctly. Users will have a different experience, depending on the users browser and what plugins they may or may not have installed.
Typically, browsers will prompt users with a yellow bar across the top, letting them know that additional software or plugins are required. They must then choose to install these. Many sites will add instructions with a few graphics to help users through this process
