When the user hovers over the link, an audio file starts playing.

The actual behaviour may depend on the user agent. On Windows XP, the following behaviour was observed. In Internet Explorer, the audio file was loaded in an instance of Windows Media Player. In Firefox 2.0 and Seamonkey 1.1, audio file was played by QuickTime (in the same tab as the referencing file). In Opera 9.0, the audio file started playing in the background, with no audio plugin being visible.

The user initiated the change of context.

The user hovered over the link, which initiated a change of user agent.
