The AVerMedia AVerTV WDM Audio Capture (878) driver allows Windows to communicate with the audio capture component of a compatible AVerMedia TV tuner or capture card. It helps supported recording applications access incoming sound, making it an important part of a working TV viewing or video capture setup.

Key Features

• Audio capture support: Provides the connection between compatible AVerMedia hardware and software used to capture sound from a supported input.
• WDM integration: Uses the Windows Driver Model interface so compatible applications can recognize and access the audio capture device.
• Device identification: Helps Windows identify the audio component correctly rather than leaving it listed as an unknown or unconfigured device.
• Capture setup compatibility: Works alongside the appropriate video capture and tuner drivers; this audio driver alone does not configure every function of the card.

How to Install

1. Confirm your hardware and Windows version. Open Device Manager and check the device name or hardware IDs. Before downloading, verify that the package matches your AVerMedia card, your Windows edition, and its 32-bit or 64-bit architecture. For Windows 11, 10, 8, or 7, check the individual package’s compatibility details rather than assuming one legacy driver supports every system.
2. Download and prepare the driver. Save the matching package to your computer and extract it if it is compressed. Close any TV viewing or recording software before starting installation.
3. Run the installer or use Device Manager. If the package includes a setup program, follow its instructions. Otherwise, right-click the audio capture device in Device Manager, choose “Update driver,” and browse to the extracted driver folder.
4. Restart and check device status. Restart Windows if prompted, then confirm that AVerMedia AVerTV WDM Audio Capture (878) appears without a warning icon. If Windows rejects the driver as incompatible or unsigned, look for a suitable package instead of disabling security protections.
5. Test audio in your capture application. Select the appropriate audio capture device and input, check recording levels, and make a short test recording. If video works but sound is missing, review cable connections, input selection, and any additional drivers required by the card.

Common Issues and Fixes

• Install fails or rolls back: The 878 WDM package is old and may be unsigned or blocked on 64-bit Windows. Run the installer as administrator, use Compatibility Mode for the listed Windows version, and temporarily disable driver signature enforcement only if you trust the source.
• Device not detected: Check Device Manager for an unknown multimedia audio controller or code 10/28. Reseat the PCI card, rescan hardware, and install the matching WDM video capture driver first; the audio capture device often depends on the tuner/capture function being recognized.
• Version conflicts: Remove older AVerMedia/BT878 drivers, including hidden devices, with “Delete the driver software,” reboot, then install one matching package. Avoid mixing generic BT878 drivers with AVerMedia WDM audio.
