Question

Can anyone help me on playing a file from a memorystream using FMOD or any other way?

So far i have this:
Variables

    private FMOD.System _fmod = null;
    private FMOD.Sound _sound = null;
    private FMOD.Channel _channel = null;

Code

        var file = File.ReadAllBytes("test.ogg");
        //MessageBox.Show("Bytes from file: " + file.Length);

        FMOD.Factory.System_Create(ref _fmod);

        var result = _fmod.init(2, FMOD.INITFLAGS.NORMAL, (IntPtr)null);
        if(result != FMOD.RESULT.OK) ShowError(result);

        var info = new FMOD.CREATESOUNDEXINFO();

        result = _fmod.createStream(file, MODE.CREATESTREAM, ref info,  ref _sound);
        if (result != RESULT.OK) ShowError(result);

Any help would be greatly appreciated

Firstly I highly recommend you take a look at the "loadfrommemory" example that ships with FMOD (it has a C# version too). But to answer your question here:

1. You need to populate some members of the FMOD.CREATESOUNDEXINFO structure:

   info.cbsize = Marshal.SizeOf(info); info.length = file.Length;

2. You need to tell FMOD you are providing in-memory data with the OPENMEMORY flag:

   result = _fmod.createStream(file, MODE.CREATESTREAM | MODE.OPENMEMORY, ref info, ref _sound);

That should be all you need to get going.
