If your sound is not working on Windows 10 or Windows 11, if you are seeing a red cross on the speaker icon, or if the Realtek audio driver is missing from Device Manager, then the Realtek Audio Driver may be missing, corrupted, or not installed properly.
In this guide, I will show you how to download and install the Realtek Audio Driver for Windows 10 and Windows 11 using the official method. This is a safer option because you do not need to use third-party driver updater tools or unknown driver websites.
When Do You Need to Install the Realtek Audio Driver?
You may need to reinstall the Realtek Audio Driver if you are facing any of these problems:
- No sound on Windows 10 or Windows 11
- Red cross mark on the speaker icon
- Realtek Audio missing from Device Manager
- Realtek Audio showing a yellow warning icon
- Speaker or headphone output not showing in Sound settings
- Audio stopped working after a Windows update
- Realtek High Definition Audio Driver is corrupted
If you are facing any of these issues, follow the steps below carefully.
Step 1: Check Realtek Audio in Device Manager
First, we need to confirm whether the Realtek driver is actually missing or corrupted.
Right-click on the Start button and open Device Manager. Now expand the section called Sound, video, and game controllers.
Here, check if Realtek Audio or Realtek High Definition Audio is listed.
If you see Realtek Audio with a yellow warning icon, that usually means the driver is corrupted or not working properly. If you do not see Realtek Audio at all, that means the driver may be missing from your system.
Step 2: Uninstall the Corrupted Realtek Driver
If Realtek Audio appears with a yellow warning icon, you should remove the corrupted driver before installing the fresh driver.
Right-click on Realtek Audio and select Uninstall device. If you see an option that says Delete the driver software for this device, check that box and click on Uninstall.
This will remove the old corrupted driver from your computer.
After uninstalling the driver, restart your computer once. Restarting is important because Windows needs to refresh the audio device configuration before you install the new driver.
Step 3: Open the Official Realtek Website
Now we will download the official Realtek audio driver.
Open your browser and go to the official Realtek website using the link below.
Once the Realtek website opens, click on the three horizontal lines at the top and go to Downloads.
Now select Computer Peripheral ICs. From the drop-down menu, choose PC Audio Codecs.
Step 4: Select High Definition Audio Codecs
After opening the PC Audio Codecs section, you will see two main options:
- AC 97 Audio Codecs
- High Definition Audio Codecs
If you are using Windows 10 or Windows 11, choose High Definition Audio Codecs.
Do not select AC 97 for modern computers. AC 97 is for very old Windows XP-era systems and is not suitable for most modern Windows 10 or Windows 11 PCs.
Step 5: Open the Software Download Page
On the High Definition Audio Codecs page, you may see different ALC chip models like ALC888, ALC892, or similar models.
You do not need to worry too much about selecting your exact audio chip model. Click on Software next to the listed High Definition Audio Codec option. Realtek provides a High Definition Audio driver package that supports many common Realtek ALC audio chipsets.
Step 6: Download the Windows 64-bit Driver
On the software page, look for the latest Realtek High Definition Audio Driver package for Windows.
For most modern Windows 10 and Windows 11 computers, download the Windows 64-bit version. Most modern PCs use 64-bit Windows, so this is the correct option for most users.
Click on the download icon. Then accept the terms and conditions and click on Download this file. If a captcha appears, complete it to start the download.
Step 7: Install the Realtek Audio Driver
Once the driver file is downloaded, open the downloaded file. If it is a compressed file, extract it first. Then double-click on the setup file.
If you see a User Account Control prompt, click on Yes.
Now the Realtek installation wizard will open. Click on Next and follow the on-screen instructions.
The installation process may take some time. Do not close the installer while it is installing the driver.
Step 8: Restart Your Computer
After the installation is complete, the setup will ask you to restart your computer. Click on Restart or restart your system manually.
This step is important because the new audio driver will work properly only after Windows restarts and loads the Realtek audio service and driver files.
Step 9: Select Realtek Speakers in Sound Settings
After restarting your PC, right-click on the speaker icon in the taskbar and open Sound settings.
Under the Output section, make sure Speakers Realtek Audio or Realtek High Definition Audio is selected.
If your speaker or headphone is connected but another output device is selected, you may still not hear sound. So make sure the correct Realtek output device is selected.
Step 10: Confirm Realtek Audio in Device Manager
You can also confirm the installation from Device Manager.
Right-click on the Start button and open Device Manager. Expand Sound, video, and game controllers.
Now check if Realtek Audio or Realtek High Definition Audio is listed without any yellow warning icon.
If Realtek Audio is showing normally, that means the driver has been installed successfully.
What If Realtek Audio Still Does Not Work?
If your audio still does not work after installing the driver, try these fixes:
- Restart your computer again.
- Check if the correct output device is selected in Sound settings.
- Disconnect and reconnect your speaker or headphone.
- Run the Windows audio troubleshooter.
- Check if audio is muted from the speaker icon.
- Try installing the audio driver from your laptop or motherboard manufacturer’s official support page.
- Check Windows Update for optional driver updates.
For branded laptops like Dell, HP, Lenovo, Acer, Asus, or MSI, the manufacturer’s support page may sometimes provide a more customized Realtek driver for your exact model. So if the generic Realtek driver does not work properly, try the official driver from your device manufacturer.
Final Words
This is how you can download and install the official Realtek Audio Driver on Windows 10 and Windows 11. If your Realtek audio driver was missing, corrupted, or showing a yellow warning icon in Device Manager, reinstalling the official driver can help restore sound on your computer.
Always use the official Realtek website or your device manufacturer’s support page for driver downloads. Avoid third-party driver tools and unknown websites because they can be risky and may install the wrong driver.
After installing the driver, restart your PC, select the correct Realtek output device in Sound settings, and confirm that Realtek Audio is listed properly in Device Manager.
