This is happened because, in Windows 10 OS, the Realtek sound driver is downloaded and installed automatically from Microsoft Update and this driver package contains only the basic drivers for your sound card and does not contain the Realtek HD Audio Manager application. The Realtek High Definition Audio Manager application is installed when you install the Realtek HD audio driver from the support site of your motherboard, (or your PC) manufacturer, or from the official Realtek support site.īut in many computers, especially in Windows 10 based PC's or Laptops, the Realtek Audio Manager, is missing from the taskbar. The 'Realtek HD Audio Manager' is an easy tool to control the sound and to tweak several audio settings on Windows 10, 8 or 7 desktops or laptops, when a Realtek Sound card device is installed on the system.
