I bought the sound card to the whistling noise and disgusting the onboard card rid. Obwohll I've never even great things around plugged on the motherboard, the assembly with the aid of the mainboard plug plan was simple and very well explained. With my Win8.1 I had no problems, but I have loaded my beta driver from a driver Portal down because on the supplied CD existed no suitable version. Too bad, but I can live well. Technically sound can be heard really the card, who is accustomed to the onboard sound-mud, will definitely feel the part as an enrichment. In music, as well as in games and movies more details come to light. Verry nais! I give 4 out of 5 stars for a nice piece of hardware, only the lack of software is a small, annoying little limp, but the leaves well cope.
