C-Media AC97 Audio Device Driver

The C-Media AC97 Audio Device driver enables Windows to communicate with compatible AC’97 audio hardware, supporting sound playback and microphone input. If you have reinstalled Windows, lost audio, or found an unidentified multimedia device in Device Manager, you may need to install the correct driver to restore sound.

Key Features

• Audio playback support: Allows compatible onboard audio hardware to deliver sound through connected speakers or headphones.
• Recording functionality: Enables microphone and line-in inputs where these connections are available on your computer.
• Windows audio integration: Helps Windows recognize the audio device and make its supported playback and recording controls accessible.
• Legacy system compatibility: Provides a driver option for older AC’97-based computers, provided the package matches the hardware, operating system, and system architecture.

Before choosing a C-Media AC97 Audio Device driver download for Windows, confirm your hardware details. Although this listing identifies Realtek as the vendor, C-Media and Realtek are different audio-chip manufacturers; their drivers should not be assumed interchangeable. Check the device’s hardware IDs in Device Manager or consult your computer manufacturer’s specifications.

How to Install C-Media AC97 Audio Device Driver

1. Identify your audio hardware. Open Device Manager, locate the audio or unknown multimedia device, and select Properties > Details > Hardware Ids. Use these identifiers to confirm that the download matches your device.
2. Check your Windows version. This listing covers Windows 10, 8.1, 7, Vista, and XP. Confirm that the individual package supports your version and its 32-bit or 64-bit architecture. For Windows 10/11 systems, do not assume Windows 11 compatibility from Windows 10 support.
3. Choose a compatible package. Look for the latest version approved for your specific hardware and Windows release. If selecting a free download, verify its source and compatibility notes before running it.
4. Install the driver. Extract the downloaded archive if necessary, then run its setup program. If no installer is included, use Device Manager > Update driver > Browse my computer for drivers and select the extracted folder.
5. Restart and test. Reboot your computer, check the default playback device in Windows sound settings, and test your speakers and microphone.

Keep a copy of your working driver before applying an update. A newer package may resolve specific audio problems, but compatibility matters more than version numbers—especially with legacy AC’97 hardware. If sound stops working after an update, use Device Manager’s Roll Back Driver option when available.
