The AVerMedia A336 Mini Card Hybrid ATSC QAM is an internal TV tuner that requires a driver to communicate with Windows and compatible television-viewing software. Installing the appropriate AverMedia driver helps your computer recognize the tuner and makes its supported reception functions available to your TV application.

Key Features

• Device recognition: Allows Windows to identify the A336 tuner correctly rather than listing it as an unknown multimedia device.
• ATSC and QAM tuner access: Enables compatible software to access supported digital TV reception modes. Channel availability depends on your antenna or cable connection, local broadcasts, and whether cable channels are unencrypted.
• TV application integration: Provides the hardware interface needed by compatible applications for watching and recording available broadcasts. TV software may require a separate installation.
• Windows driver support: When selecting a package for Windows 11, 10, 8, or 7, match it to your operating system and architecture. Older tuner hardware may require a system-specific driver, so confirm compatibility before installing.

How to Install

1. Check your system and hardware. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. Open Device Manager to verify that the installed tuner is the AVerMedia A336 Mini Card Hybrid ATSC QAM; check its hardware IDs if the name is not displayed.

1. Choose a matching driver package. Download a driver that explicitly supports your tuner and Windows version. For a tuner supplied inside a laptop or prebuilt PC, check the computer manufacturer’s compatibility guidance as well.

1. Extract and install the driver. Unzip the download if necessary, then run the installer with administrator privileges. If there is no installer, open Device Manager, right-click the tuner, select “Update driver,” and browse to the extracted driver folder.

1. Restart and verify detection. Restart your computer if prompted. Return to Device Manager and check that the tuner appears without a warning icon. If Windows rejects the package, use a compatible signed driver rather than disabling security checks.

1. Configure your TV software. Connect a suitable antenna or supported cable feed, open a compatible TV application, and select the A336 as the tuner. Choose the appropriate reception mode and run a channel scan. A successful driver installation alone does not guarantee channel reception.

Common Issues and Fixes

• Install fails or rolls back: Run the AVerMedia installer as administrator. For the legacy A336 package, use Windows driver-signature enforcement bypass only if required, remove other TV-tuner drivers, and reboot before retrying.
• Device not detected: Reseat the mini PCIe card and antenna connection. Check Device Manager for unknown or disabled entries, then manually update the driver via “Browse my computer” and reboot.
• Version conflicts or no channels: Uninstall old AVerMedia/Media Center tuner entries, delete hidden devices, and reboot. Rescan as ATSC for antenna or clear QAM for cable; encrypted QAM channels will not tune.
