You are setting things up in the wrong order. Try changing it to this: if (listVmItem != null) { var file2 = await _finalStorageFolder.GetFileAsync(listVmItem.FileName); var stream = (await file2.OpenReadAsync()).AsStream().AsRandomAccessStream(); AudioPlayer.MediaOpened += AudioPlayer_MediaOpened; AudioPlayer.CurrentStateChanged += AudioPlayer_CurrentStateChanged; AudioPlayer.SetSource(stream, file2.ContentType); AudioPlayer.Play(); } and move these calls to the MediaOpened handler: TimeSpan recordingTime =...
How to use existing camera app(not create one using MediaCapture) and take picture in windows phone 8.1(WinRT)?

Windows Phone 8.1 - HttpClient SendRequestAsync will never return with a response
