First confirm that Windows is using the intended speakers, headphones, or microphone and record any Device Manager error code. Install Windows updates, then update the Realtek device through Device Manager. If Windows finds no newer driver, use the support page for the exact laptop, desktop, or motherboard model. Reinstall or roll back the driver only after the safer checks match the way the problem started.
Open Settings > System > Sound and select the intended Output or Input device. Then open Device Manager > Sound, video and game controllers and record the Realtek device name and any yellow warning or error code.
Open Settings > Windows Update > Check for updates. Install offered updates, including a clearly matched audio update under Advanced options > Optional updates, then restart the PC.
Right-click the Realtek device, select Update driver > Search automatically for drivers, and restart if Windows installs one. Do not use a third-party driver-download website.
If Windows says the best driver is already installed, open the official support page for the exact laptop, desktop, or motherboard model and Windows 11 version. Install its audio package only when the model matches.
If the device still shows a corruption error, right-click it, select Uninstall device, confirm, and restart. Windows should detect the hardware and reinstall a compatible driver. Test before installing another package.

Roll back only after a recent update
If sound stopped immediately after a driver or Windows update, open the Realtek device Properties > Driver and use Roll Back Driver when that button is available. Restart and test.
Test built-in speakers, headphones, and microphone separately. If the same code returns, give the PC or motherboard maker the exact model, Windows build, Realtek device name, driver version, and error code.

If it does not work
If Windows audio works but one app is silent, check that app in Volume mixer before reinstalling a system driver.
If Realtek is absent and Device Manager shows an unknown device, use the PC maker's hardware scan and exact model support page instead of choosing a similar Realtek package.
