I'm kinda clueless here, it seems like a bug. On the emulator I can't load songs from the MediaLibrary (it's empty), and I don't have a device yet. What method are you using? Did you try this one maybe? http://msdn.microsoft.com/en-us/wp7trainingcourse_2dgamedevelopmentwithxnapart2lab_topic2.aspx

I have the same question with windblow. It will be great that you have insight on this. Thanks!

Hi, I have a question regarding integrating the XNA's MediaLibrary

I am trying to use MediaLibrary to load all the songs and then play the songs using MediaPlayer.play(song). However, I find that it only works when the emulator is started by Visual Studio debug mode. Otherwise, the MediaLibrary cannot find any song in the mediaLibrary(including on the real phone). A workaround is if I enter Gamehub first, then run my application, it will load all the songs from the MediaLibrary with no problem. I know this might be a bug in WP7. But do you have any idea what does the "entering gamehub" do so that the songs in the MediaLibrary is accessible again?

Thanks!

I couldn't reproduce it, but you can still stop it in the Application_Closing and Application_Deactivated (App.xaml.cs) methods by stopping its DispatchTimer.

When I add the XNAAsyncDispatcher to my application I get this exception on exit:

A first chance exception of type 'System.Threading.ThreadAbortException' occurred in Microsoft.Xna.Framework.dll

Do you know why this is happening?

Thanks

Thanks for your really useful article,

I had some problems with updating that "FrameworkDispatcher", and you solved it ;)

Thanks a lot!

Now everything is working fine.

Hi,

you have to put this in the App's constructructor (in App.xaml.cs)

public App()
{

this.ApplicationLifetimeObjects.Add(new XNAAsyncDispatcher(TimeSpan.FromTicks(333333)));

};

and this is the ApplicationLifeTimeObjects (but i think you have that figured out):

Hello,

thanks for your post. I want to play a simple sound after pressing a button in Silverlight with the XNA-Framework. I realize this with your code snippet, but it don't work. The program told me, that there was no definition for ApplicationLifetimeObjects. Where have I put that? I've put it in the constructor of my MainPage, was this wrong?

Thanks.

Thanks, you're right, something is wrong with the snippet boxes, the copy icon is not appearing. I'll try to fix it.

Thanks for posting this - really helped me out. FYI, having the line numbers in your code samples make it a pain in the ass to copy your code.

after you saved it:

using (var isf = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    using (var isfstream = new IsolatedStorageFileStream("effect.wav", FileMode.Create, isf))
                    {
                        isfstream.Write(soundByteArray, 0, (int)soundByteArray.Length);
                    }
                }

you can play it like this:

using (var isf = IsolatedStorageFile.GetUserStoreForApplication())
                {
                    using (var file = isf.OpenFile("effect.wav", FileMode.Open))
                    {
                        byte[] buffer = new byte[file.Length];
                        file.Read(buffer, 0, (int)file.Length);
                        effectSE = new SoundEffect(buffer, sampleRate, AudioChannels.Mono);
                    }
                }

                effectSE .Play();

IsolatedStorage.

hi,

are you using the IsolatedStorage (eg. download the sound on runtime and saving to IsolatedStorage) or just adding to the project as content? If the latter, make sure it's build action is set to "Content" (in the Properties window)

I'm trying to play an audio file from isolatedstorage, but I'm getting an error when trying to set the uri. Can you give a better example of playing an audio file from isolatedstorage?

thanks,

Darick
