Monogame SoundEffect Crash

Question

I am trying to re-program some old Arcade games in C# with the Monogame engine. However, I have encountered a certain problem.

Since my code tends to be a bit messed up, I am often not taking the effort to reset everything when the player successfully completes the game. Instead, I am simply closing the current Game-instance and opening a new one, like this: (in Program.cs)

    if (startgame)
    {
        do
        {
            using (var game = new Game1(level, points, soundOn))
                game.Run();
        } while (continueGame == true);
    }

Now the problem. In Game1, I am declaring and playing various SoundEffects. The first run everything works fine, but in all following Game1-instances, my program will always throw an System.AccessViolationException related to SharpDX.XAudio2.dll at the moment I am calling the .Play()-Method of a SoundEffect.

I tried playing SoundEffectInstances instead of the actual SoundEffects. Now it doesn't crash anymore, but is being completely silent from level 2 on instead.

Do you know what could be the reason of this error? Is my game-restarting loop causing problems I did not know about?

Thank you in advance.

(I am using Win 7 64 Bit, VS Express 2015 and Monogame 3.6)

Yes. Do not do it. You are destroying the whole game object just to reset the game. This is a very bad style, because it destroys the whole instance and everything that is connected to it. If you use static variables within it, they will remain in memory which may be the problem you have.

If you want to reset your game, simply write a Reset-method for everything and call these instead. Cleanup and nice code is something you should use instead of terrible hacks.

Can you show more code, so it is possible to understand, what went wrong?

PS: Never write something like while (continueGame == true) always go for while (continueGame).
