The AVerMedia AVerTV WDM Audio Capture (878) driver lets Windows communicate with the audio-capture component of compatible AverMedia TV tuner hardware. It helps supported recording and TV-viewing applications receive sound from the card. For Windows 11, 10, 8, or 7, check the individual driver package’s compatibility before installing, as this legacy hardware may not have a suitable driver for every version.

Key Features

• Audio-capture support: Provides the interface needed for compatible software to access the tuner card’s audio-capture functionality.
• WDM integration: Uses the Windows Driver Model to connect the capture device with applications that support WDM audio sources.
• Device identification: Allows Windows to recognize the audio-capture component when the correct driver is installed.
• Capture configuration: Makes supported audio controls available to compatible applications; the options depend on the hardware, driver, and software in use.

How to Install

1. Confirm the hardware match. Open Device Manager and locate the capture device, which may appear under “Sound, video and game controllers” or as an unidentified device. Check its hardware IDs in Properties if you are unsure whether it is the AVerMedia AVerTV WDM Audio Capture (878).

1. Check your Windows version. Confirm whether you use Windows 11, 10, 8, or 7 and whether the system is 32-bit or 64-bit. Select a package that explicitly supports both your device and operating system. An older driver should not be assumed to work on newer Windows releases.

1. Prepare the driver package. Download the matching package and extract it if it is compressed. Close any TV-viewing or capture applications before starting the installation.

1. Install the driver. Run the included setup program, if available, and follow its prompts. Alternatively, right-click the device in Device Manager, choose “Update driver,” select “Browse my computer for drivers,” and point Windows to the extracted folder. If Windows reports an incompatibility or signature problem, look for a supported package rather than bypassing security checks.

1. Restart and test audio capture. Restart if prompted, then check Device Manager for warnings. Open your capture application, select the appropriate audio source, and make a short test recording. If video works but sound is missing, verify the application’s audio settings and any audio connections required by the tuner card.

Common Issues and Fixes

• Install fails or driver is unsigned: The 878 WDM package is legacy, so Windows may reject it. Run the installer as administrator. If setup fails, update manually via Device Manager > Sound, video and game controllers > Have Disk and point to the INF. On 64-bit Windows, use compatibility mode or temporarily disable driver signature enforcement only for a trusted package.
• Device not detected: Check Device Manager for unknown or multimedia devices. Reseat the PCI card, try another slot, and confirm the tuner/audio function is enabled in BIOS if applicable. Reinstall motherboard chipset drivers before retrying.
• Version conflicts: Uninstall existing AVerMedia TV/audio drivers and software first, choose “Delete the driver software,” reboot, then install one matching WDM package. Avoid mixing generic Windows audio drivers with AVerMedia components.
