Do you know the make and model of this USB sound card?
What is the make and model of the 7.1 speakers?
My best guess
For getting "Expanding Stereo" audio with this USB sound card.
First set System input to 2 CH (2-channel)
As it has the Output Mode set to 7.1, it might automatically reconfigure itself to expanded stereo,
so the 2-channel audio comes out all 8 speakers
If just switching the System Input to 2 CH does not solve the issue.
Then click on the DSP Mode button and see what options it gives you.
Your looking for something called Expanded Stereo, or something that fits the same description.
