Premium USB 6-Channel Surround Sound Card Adapter with Optical Audio Input Output for PC

First of all, when I plugged it in, it was a slight improvement over a stereo configuration when using the 3 jacks for 5.1 surround. That being said, the balance was still off, so I downloaded and installed the software to fix that. This was my biggest mistake - all of my output devices disappeared (as in the screenshot), and, as the software took control of the USB sound card, it messed up the default settings so that the balance was even further off (Center and Right channels wayy louder than the others). Unable to fix this in the clunky software - It wasn't letting me change it to the 5.1 config - I decided to uninstall it. One restart later, and all of my Output devices were still gone, the balance for the device was still off, and I wanted to chuck it out of the window. It took me hours to restore my output devices, but I cannot figure out the balance. Support was not able to provide me with an alternate software, so I plan on writing one myself since I saw the potential in the hardware at unboxing.TL;DR:The software is a nightmare, don't install it. Works fine out of the box for the 3-port 5.1 surround. One star because of the hours I wasted attempting to fix what the software did to my PC.

I wrote them, and they just have the Win7 software and drivers. There is not webpage to support this product anymore... So buy it on your own risk.
