I submitted a background audio app for certification and has failed with two reasons

I submitted a background audio app for certification and has failed with two reasons in which I could not figure out why.

Reason 1:

This app failed to correctly respond to at least one of the play,
pause, or play/pause events.

I understand that the MediaControl events for Play, Pause, Stop and PlayPause need to be catered, and have done so (and tested on both tablets and local devices that they are working) in the code. However, due to the reason that stopping a media stream and restarting it requires a longer-than-expected time, I used MediaElement.Pause() for both “Pause” and “Stop”.

I read another post who had similar problem at the certification phase. Somebody recommended to use MediaElement.PlaybackRate = 0; instead. However, this is not ideal for long pauses as the stream will not move on.

What I wish to know is am I doing this the right way? For all my MediaControl events I have made sure that the MediaControl.IsPlaying property is correctly set as well.

Also, another reason it failed was this:

App failed the Perf test in the Windows ACK. See the following links
for more information: Test cases ran:
http://msdn.microsoft.com/en-us/library/windows/apps/hh920274.aspx

I have ran my app against the ACK and it all passed. The only thing I can think of is that the app does not enter suspend mode when the hardware (or on-screen) media control pause button is pressed. I have placed a debugger in the App_Suspending event but it never hits there.

As the description is too vague I am not sure if this is the problem. But if it’s the case, can I know how do I force the app to enter suspended mode? I tried looking in the Window.Current class and Application.Current class, but to no avail.

Thanks!

    After nearly 10 attempts in releasing the app, I finally got to the root of the problem, thanks to some guessing work by the folks at Microsoft too.

    My app will automatically start the MediaElement streaming after the app is started. The background-capable audio will prevent the app from passing WACK because it will never enter suspended mode!

    So, in order to get pass the store’s WACK I had to remove the auto-starting feature, and now the app is in the store! (Phew).
