I am facing a sound issue on my system. The audio is not working. I checked in device manager and found that there is some problem with Microsoft UAA bus driver. I tried location the update of driver from web but somehow it is not available. I am having a hp computer. While in my system Realtek ALC888s looks like is installed already. I need some help here to collect the most latest driver updates and configure it on my system. Can anyone here help me on the problem.
