How to use two audio devices simultaneously with Windows 7?

I have an audio connector on board (Asus P8H67-I) and an USB audio card (Teufel). How can I use the two devices simultaneously?

As far as I can see I have to set one device to the standard output device. I am looking for a way to set both to the standard output device in order to hear on both the same sound.

Any ideas?

Windows does support multi streaming audio.

Microsoft calls it stream routing.

This actually existed back in Vista. . .

For a hands on example, play something on Youtube. Fire up Windows Media Player. Go to Tool, Options, then click on the Devices Tab. Doubleclick the speakers and switch the output to, say from Back Speakers to Front Headphones. Now you have Youtube through the Back connections and an MP3 going on the front headphones.

Media Player Classic along with VLC also support this feature, again, which was available since Vista. In MPC, it's an obscure listbox on the bottom of the Output options. VLC, switch to Advanced and look under the Audio tree.

As long as your Audio drivers are updated and the Application supports it, then you are good to go. Some programs can be fooled into playing onto another output device by switching the default device after you've hit play. . .
