Audio Output on Separate Sound Card (1 Viewer)

[Dadeo]

I have onboard audio and a separate Aureal Vortex 8830 soundcard. I have specified the audio output in the audio renderer settings for Television and the Movie and Music player, and it works, but is there any way to simply direct all audio output to the second soundcard? The system sounds, remote sounds etc still output to the computer speakers.

In particular, how do I set the volume control to mute, or increase/decrease the volume on the second sound card, not the default sound for the computer.

If not, is this something that will be available in MediaPortal II?

Thanks.
