Smooth Streaming SDK for Windows 8 - Error with Headphones Plugged

Question

I'm doing some tests with the Smooth Streaming Client SDK for Windows 8, and I have a very basic application playing a fullscreen video:

private MediaExtensionManager extensions = new MediaExtensionManager();

public MainPage()
{
    this.InitializeComponent();
extensions.RegisterByteStreamHandler("Microsoft.Media.AdaptiveStreaming.SmoothByteStreamHandler", ".ism", "text/xml");
extensions.RegisterByteStreamHandler("Microsoft.Media.AdaptiveStreaming.SmoothByteStreamHandler", ".ism", "application/vnd.ms-sstr+xml");
}

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    string url = "http://my.smooth.streaming.url/manifest";
    this.slPlayer.Source = new Uri(url);
    this.slPlayer.Play();
}

This seems to be working fine, unless I plug my headphones, at which point the application stops working. Adding a handler for the MediaFailed event informs I'm getting a MF_MEDIA_ENGINE_ERR_SRC_NOT_SUPPORTED error.

Any idea what may be causing this?

Badaro, I just tried this and was not able to repro the problem (on both x86 & x64, both starting with and without headphones and switching during playback). My guess is that you are either: 1) running into a driver issue. 2) there is something specific about the way your stream is encoded that causes this.

I suggest ruling out #1 by trying on a few different machines. or, rule out #2 by trying the sample smooth SDK stream: http://mediadl.microsoft.com/mediadl/iisnet/smoothmedia/Experience/BigBuckBunny_720p.ism/Manifest

Don't have another Win8 machine to test right now, but after doing more tests I'm leaning towards "bizzare driver issue". I'll accept this answer for now, and I'll update if I find something else. — Badaro, Mar 22 '13 at 18:16
