How to fixAUDIO-CONTROLLER-NO-SOUND

Realtek/Intel audio controller no sound (Code 10)

What this error means

AUDIO-CONTROLLER-NO-SOUND shows up as a low-severity motherboard fault. The onboard audio controller reports Code 10 (This device cannot start) in Device Manager, resulting in complete loss of audio. This is extremely common after Windows updates that replace audio drivers, or when the Realtek HD Audio driver conflicts with Intel's Smart Sound Technology (SST) driver on modern platforms. Work through the steps below in order.

Before you begin

Save open work and back up important files. Use instructions for your exact device and software version. If Windows cannot start, see the startup guide.
