Hello. I have HP Probook 4730s. After I installed Windows 8.1 update 1 the sound driver stopped working properly. When I want to play some music, video or even system sounds, sound appears after 1-2 minutes. At that time HDD usage is 100% cause of windows audio device graph isolation. I’ve installed that IDT High Definition (HD) Audio Driver from HP’s driver support site, but that’s not working. As I see in device manager driver’s release date is 24.10.2012. I think, it’s too old for Windows 8.1. Can you help me? Is there any other newer version of that sound driver? Also I’m sending two pictures where are HDD usage and driver release date.
