audio/wav data URIs stopped working in Mobile Safari in iOS 5.1

Status:Open Resolved:
Product:Safari Product Version:5.1
Classification:Other Bug Reproducible:Always
 
Summary:
I am trying to dynamically generate audio data in javascript and then play it.  The method is build a wav file and encode it into a data URI. (https://en.wikipedia.org/wiki/Data_URI_scheme)  Then playing it by putting the data URI into a HTML5 audio element or by calling open() on it.

This works on the desktop, and used to work in older versions of Mobile Safari.  Now it just displays a dialog saying "The operation could not be completed"

Steps to Reproduce:
1. In Safari on iPod/iPad/iPhone with iOS 5.1
2. Goto http://tadpol.github.com/Avrian-Jump/avrianjump.html
3. Tap on the right arrow button on the lower right hand side of the page. (➜)
4. Get the dialog saying: "The operation could not be completed"

Expected Results:
Expected that it will play the sound data.

Actual Results:
Get the dialog saying: "The operation could not be completed"

Regression:
Prior iOS version 5.0 would play the sound.

Notes:

A web page doing a very similar thing: http://www.sk89q.com/playground/jswav/
