MediaElement does not play a stream

Question

So basically I just opened a new store C# blank app and put this in cs file:
private void MediaElement_MediaFailed(object sender, ExceptionRoutedEventArgs e)
gumb.Content = e.ErrorMessage;
System.Diagnostics.Debug.WriteLine(e.ErrorMessage);
private async void gumb_Click(object sender, RoutedEventArgs e)
var myUri = new Uri (string.Format("http://173.192.137.34:8042"), UriKind.RelativeOrAbsolute);
var uriStreamReference = Windows.Storage.Streams.RandomAccessStreamReference.CreateFromUri(myUri);
var uriStream = await uriStreamReference.OpenReadAsync();
MediaElement.SetSource(uriStream, "audio/aac");
MediaElement.Play();
And I put this code in XAML:
<Grid>
<Button x:Name="gumb" Content="Play" Click="gumb_Click" />
<MediaElement x:Name="MediaElement"
Width="400"
AutoPlay="True"
AreTransportControlsEnabled="False"
AudioCategory="BackgroundCapableMedia"
MediaFailed="MediaElement_MediaFailed"
/>
</Grid>
And so the Play button only generates this output: MF_MEDIA_ENGINE_ERR_SRC_NOT_SUPPORTED : HRESULT - 0xC00D36C4
Note that when you load that streaming URL in VLC player it plays normally and says that stream is of type M4A/AAC which I have found to be supported by windows phone store app (documentation).
There is one more possible stream (of the same radio station) which also does not work:
http://173.192.137.34:8006/
One more interesting fact is that I have found a few internet streaming radio stations that DO play in my simple code so it feels like this codec maybe unsupported by my code, but I was unable to understand what is missing. So far... Although I'm already wrecking
my brain for weeks on this.
I am developing this app primarily for Windows Phone 8.1 / RT but I would like it to be universal, if possible, for future to make a version for tablets.
One other thing is that this same code WORKS on my Windows 8.1 store app, on my x86 tablet/laptop. But I cannot understand why it does not work on Windows Phone. I am deploying on Lumia 930 with Denim, but I suspect it does not matter which Lumia 8.1 is
it.

Those appear to be Shoutcast streams and report content type audio/mpeg.
Windows Phone does not support Shoutcast natively, you would need get or write a MediaStreamSource implementation which can handle shoutcast streams.
