I am trying to test if some audio files we currently have, can be played via HTML5.

The html code is as follows:

```
<audio width="720" height="405" controls src="https://machinename/media/play?ID=2" type="audio/wav"></audio>

```

When the page loads, it seems to be doing something, and later fails with a message that says `Invalid source`.

If i then look at F12 for more debugging info, it says:

> 
> AUDIO/VIDEO: Unknown MIME type
> 
> 
> 

The content being rendered by the tag `src="abc"` is a wav file.

What am i missing? I am testing in IE11 and Chrome 43.
Any help much appreciated.
