Separate sound devices?

Is there a way to send radio communications uot to a headset while playing other sounds through speakers?

Actually I don't know of any game that supports multiple sound devices.
You can send the sound of the game to one device and the rest (windows sounds, any other program) to another, but that's about it.
(And I'm not even sure this is going to work for an OpenAL game like WCS.)

Thanks for the answer.
