AudioMix wakelock in Android Monogame

Thank you @TomRumilus for your fix. I had the same problem using CocosSharp (based on MonoGame).
Since the OpenALSoundController is an internal class I couldn’t use your solution. But, bases on the MonoGame source I found out that OpenTK caused the problem. Adding CleanUpOpenAL function to OnStop() solved the problem.

protected override void OnStop()
{
    base.OnStop();
    CleanUpOpenAL();
}
private void CleanUpOpenAL()
{
    try
    {
        var context = OpenTK.Audio.OpenAL.Alc.GetCurrentContext();

        if (context != OpenTK.ContextHandle.Zero)
            {
                var device = OpenTK.Audio.OpenAL.Alc.GetContextsDevice(context);

                OpenTK.Audio.OpenAL.Alc.DestroyContext(context);
                context = OpenTK.ContextHandle.Zero;

                if (device != IntPtr.Zero)
                {
                    OpenTK.Audio.OpenAL.Alc.CloseDevice(device);
                    device = IntPtr.Zero;
                }
            }
        }
        catch (Exception e)
        {
            _logger.LogMessage(LogLevel.Error, "CleanUpOpenAL FAIL msg: " + e.Message);
        }
}
