How to Install C-Media CMI8738 Drivers on Windows 11 (64-Bit)
If you've just upgraded to Windows 11 and realized your trusted C-Media CMI8738 sound card is silent, you aren't alone. This classic PCI/PCI-e audio chip has been a staple for decades, but getting it to work on Microsoft's latest 64-bit OS requires a bit of a workaround since official support has technically ended.

Here is how you can breathe life back into your audio setup. The Challenge: Official Support Status
C-Media officially no longer provides dedicated Windows 11 drivers for the CMI873x or CMI876x series. However, because Windows 11 shares much of its underlying driver architecture with Windows 10 and Windows 8.1, you can often use older 64-bit drivers to restore functionality. Step-by-Step Installation Guide 1. Download the Right Driver
Your best bet is a Windows 10 64-bit driver (often version 8.1.8.1746 or 1.1.4.1111), which is typically compatible with Windows 11.
Official Sources: While the original manufacturer's site may be limited, reputable archives like the Microsoft Update Catalog or Driver Scape often host the necessary .cab or .zip files. 2. Manual Installation via Device Manager
Since there is no "Windows 11" installer, you must point the system to the driver manually: Right-click the Start button and select Device Manager.
Find your sound card (it might appear as "Multimedia Audio Controller" under "Other devices"). Right-click it and choose Update driver. Select Browse my computer for drivers.
Point the path to the unzipped folder containing your downloaded 64-bit driver. Ensure "Include subdirectories" is checked and click Next. 3. Handling Driver Signature Issues
Windows 11 requires digitally signed drivers. If the installation fails due to a signature error, you may need to:
Temporarily disable Driver Signature Enforcement through the Advanced Startup menu.
Note: Only do this if you are confident in the source of your driver. Alternatives: Compatibility Mode
If the manual update doesn't work, try running the setup.exe from an older Windows 7 or 8.1 driver package in Compatibility Mode: Right-click the setup file > Properties. Go to the Compatibility tab.
Check Run this program in compatibility mode for and select Windows 8 or Windows 7.
