To be honest, I have not much idea about this whole Dolby Surround System or total assets. But the COMDIS Sro I-TEC USB 2.0 Audio Adapter 5.1 channel fulfills very well its purpose.
It is easy to use and after a short installation on the PC you can start. On the PC you can select options, for example, how many speakers are connected. It's really easy to use.
Disadvantages struck me about this product so far to not large. The only thing that could be improved, is the length of the USB cable, there is unfortunately only so 30cm long.
On the whole, the COMDIS Sro I-TEC USB 2.0 Audio Adapter 5.1 Channel, Audio Device, USB HID is very well suited for use with sound systems.
