Connecting a 7.1 surround

[GGisr]

Hi,
I recently bought an external USB audio box (ENMAB-8CM) and plugged in my 7.1 surround speakers.
Windows has installed the driver automatically.
The problem is, only the 2 rear speakers are working. When I configure and test my speakers through windows, ALL the speakers are working properly but when I play a song in WMP or playing a game I can only hear from the 2 rear speakers.

Any idea?

You have to buy sound card for 7.1

Just use your external speakers in surround sound mode. They'll emulate 7.1

USB doesn't output 7.1

Just use your external speakers in surround sound mode. They'll emulate 7.1

How do I do that?

Set it on your amplifier
