Realtek HD Audio Service
RealtekAudioService.exe is the background service within the Realtek High Definition Audio package that initializes and manages Realtek audio hardware. It communicates with the Realtek driver to maintain mixer controls, sample rate handling, and device switching, enabling features exposed by Realtek Audio Console. The service starts with Windows and persists to support ongoing playback and recording operations.
The service runs under the Realtek HD Audio Driver package, coordinating with the driver to expose endpoints via Windows Audio Session API. It does not perform DSP processing; it handles startup, driver communication, and configuration updates for Realtek audio features.
