WP7 audio stream problem

I'm using MediaElement to play audio mp3 stream, everything goes ok, but now I have mp3 stream that does not end with .mp3, ( http://server2.fmstreams.com:8011/spin开发者_如何学Go103) and I'm getting

AG_E_NETWORK_ERROR

I found solution to add ?ext=mp3, but it didn't work for me, any ideas?

If you are streaming live radio, the stream may be encoded by an IceCast server or ShoutCast server. To read these streams, you will need to decode the stream in memomry and pass it to the MediaElement once it has been decoded.

have a look at Mp3MediaStreamSource : http://archive.msdn.microsoft.com/ManagedMediaHelpers

and Audio output from Silverlight

I lost tons of time on this, and this is the best solution I found so far.

You also have to be sure that while you are testing, the device must be unplugged from the computer.
