VIA does not make PCI or ISA sound cards, they make chipsets and sell them to people who do.
If would have been helpful if you had included the motherboard/computer brand and model along with the VEN/DEV/SubSys numbers found in the device properties of Device Manager. With the vague info you posted, all I can suggest is to visit the VIA website.
However, I can tell you up front that VIA does not have this chipset listed in their sound drivers section. And if it's in a laptop, generic drivers from VIA would never work as they will fail install. If it's used in a laptop you must use specific drivers from the laptop maker OR special "hacked for laptops" drivers. These sites might help if this device is installed in a laptop computer:
