Hi Everyone, Okay here's the problem. My friend reformatted his computer (not using the recovery CDs) and now his realtek sound card isn't reconized. So we went to HP.com to get the drivers but when we tried to install the drivers we get a message saying that we need Microsoft's UAA bus driver. We googled and even tried contacting HP technical support but with no success. HP says we have to use the recovery CDs which we don't have and it will take about two weeks for them to send new ones. I was hoping someone here can help us out. All we need is Microsoft's UAA bus driver. Any help would be greatly appreciated. Thanks in advance.
