Making a managed wrapper around DirectSound.   

Hy there, I use .NET 2.0(C#) in my applcations and now I need the app to 
support playing multiple sounds at once. I tried to use the waveout API but 
it did not play that well, and it gave some errors on XP. I understand that 
that is an deprecated tehnology, so I want to switch to DirectSound.

My problem is that I can ask the clients who use the application to install 
DirectX. My old app(written in native C++), uses DirectSound (3,I think) and 
it works good.

Can anyone gime me some tips how to start this project? I imagine that using 
Managed DirectX is easy, but I suspect that MDirectX is not a wrapper over 
DirectSound3. 

I could really use some tips on this.Thanks very much.

Re: Making a managed wrapper around DirectSound.   

waveOut is actually not 'deprecated', it just generally limited in what it 
can do.

DirectSound is actually deprecated for game audio in favor of XACT or 
XAUDIO2, but it is still supported for appcompat reasons and due to 
dependancies for other technologies. DirectSound8 (DirectX 9.0c from Summer 
2004) is built into Windows XP as of Service Pack 2 and all subsequent 
versions of Windows. Therefore, you don't really have to worry about 
redisting the native DirectSound component unless you are supporting Windows 
XP RTM or Windows XP SP1.

Managed DirectX (MDX 1.1) is a simple wrapper for DirectDraw, Direct3D9, 
DirectSound, DirectInput, DirectMusic, and a greatly simplified usage of 
DirectShow via the AVP interface. MDX 1.1. has not been updated since April 
2005, and is itself depcreated. Again, for game usage there are new 
offerings like XNA Game Studio and the XNA assemblies. Both MDX 1.1 and XNA 
assemblies require some form of REDIST package to get them installed onto 
end-user machines, and both of these also make use of the native D3DX9 
component which itself must be REDISTed.
