Quick start
How to install a Realtek audio driver
For the best match, start with the computer or motherboard manufacturer's support page. Realtek notes that its generic packages may not include manufacturer-specific customizations.
Tip: Before replacing a working driver, record the current driver version in Device Manager. If the new package causes a problem, you can compare versions or roll back.
1
Identify the computer
Find the exact laptop, desktop or motherboard model. Manufacturer audio packages can be customized for that system.

Download the correct package
Choose the driver matching your Windows version, architecture and audio hardware. Avoid installing a package for a different codec or platform.
3
Extract if necessary
If the download is a ZIP archive, extract it first. For an EXE, double-click the installer and follow its prompts.

Restart Windows
Complete the installation and restart the computer when prompted. Check Device Manager and test speakers, headphones and microphone.
Frequently asked questions
Common questions about Realtek audio drivers and Windows.
Is RealtekAudioDriver.com the official Realtek website?
No. This site is an independent informational and driver-resource website. Realtek's official website is the appropriate source for Realtek's own generic driver packages, while PC and motherboard manufacturers may provide customized packages.
Should I use the Realtek driver or my PC manufacturer's driver?
For a laptop or branded desktop, start with the manufacturer's support page because the audio package may contain system-specific components or customizations. Realtek itself advises users to obtain manufacturer drivers when those customizations are needed.
Can Windows install a Realtek audio driver automatically?
Yes. Windows Update can provide audio drivers. If Windows does not find the right package, use the computer or motherboard manufacturer's support site and verify the hardware model.
How do I find my Realtek hardware ID?
Open Device Manager, expand Sound, video and game controllers, open the audio device's Properties, select Details, and choose Hardware Ids. The PCI or HDA identifiers can help distinguish devices.
Why did my sound stop working after a driver update?
Check the selected output device, restart Windows, inspect Device Manager for warnings, and consider rolling back the driver. If the issue began immediately after an update, the previous manufacturer package may be a useful comparison.
