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.
