Repro Steps:

[Samples attached]
AudioExample1.html works as expected
AudioExample2.html makes a GET request for the MP3 before you click play. In IE 10 it makes 2 GET request for the MP3.

Create an html5 audio element with no source and add a child source tag via javascript afterwards. The browser will start to download the source even if preload is none on the audio element.

Expected Results:

The expected behavior is for the user agent not to download any media if the preload attribute is set to ‘none’ on the audio tag.

Actual Results:
