I'm not aware of a way of doing this within .net framework. But you can use the direct sound api:

DirectSoundEnumerate to find available devices and then use the guid of the desired device in DirectSoundCreate .

Please, do not change the default device of the PC by messing around with the registry (or at all). This would be a major annoyance for your users.

Here 's some sample code for playing a sound in DirectX natively.

You could check out Managed DirectX and/or XNA. It may make life easier for you by providing you with a managed wrapper for DirectSound.
