Step 1: Click in the Windows Search button, type Control Panel, and press Enter to launch it. The best way to check whether the problem exists lies in the Control Panel. When the Realtek HD Audio Manager goes missing, then it’s likely that your computer will also suffer issues with the Realtek HD Audio driver on Windows 11. Check for Realtek HD Audio Manager in Control Panel Before we begin, you’ll need to check if the Realtek HD Audio Manager is still installed on your computer. When you can’t find the Audio Manager, or it goes missing, it’s most like a software issue and not a hardware problem. The Realtek HD Audio Manager gets installed with the driver and rests in your PC’s system tray, taskbar, or general notification panel. With that software, you can configure, tweak, and customize the sound output as per your preference. The Realtek HD Audio Manager helps to detect the audio devices like headphones, speakers, and microphones on Windows 10 or Windows 11. Worse, the Audio Manager goes missing when you install another third-party audio app that changes the sound drivers, a malware, or after a Windows Update. When the sound suddenly stops working, you will only check the volume levels but it won’t change anything. Realtek HD Audio Manager comes with Realtek’s High-Definition (HD) Audio Driver on almost every Windows 10 and Windows 11 computer.
