      The background Audio Sample doesn't work on PC, only emulator WP.
      Can you take a look?

      Hi Christian - There is a bug in the Background Audio on the //build OS that prevents an x86 audio process from starting on an x64 PC. If you update your target type in VS to x64, the sample should work.

      Hi David, yes I know that now. Got help from the Github page.

      Hello, I would like to know if it will be possible to create a universal app reproducing an audio stream with RTP (Real-time Transport Protocol) for example?

      Hello,
      thank you for your clear presentation, I would like to ask you a question.

      I currently have a C#/C++ mixed XAML app running on Windows Phone 8.1 runtime that uses a C RTP stack to listen to audio streams.

      The RTP stack is running in foreground with the application UI, this means that when the user switches to other activites the audio coming from RTP stream is not played back.

      I would like to move the RTP stack and the audio playback to a background task.

      This option was not available in XAML app running on Windows Phone 8.1 runtime, Voip like background tasks are available only for Windows Phone 8.1 Silverlight apps.

      I saw in the presentation a new Voip background tasks profile for Windows 10 Universal Apps.

      Is this profile available in XAML Universal app running on Windows Mobile 10?
      Have you any example of a Voip background task for XAML Universal app?

      Thanks
      Claudio

      Hi, I have been developing a similar application (which uses an RTP stack to play/listen audio streams) for over a year.

      I can say that, since playing an audio stream in background with RTP is only possible with a Windows Phone 8.1 Silverlight app, you should better go with Android to do such a thing!

      @Claudio:The UWP VOIP Platform is not in the early builds of Windows 10. It will be soon, and we'll post a sample on github with the others.
