The Conexant BTTUNER TVision WDM TvTuner driver helps Windows communicate with the TV-tuning hardware on a compatible capture card. It provides the Windows Driver Model (WDM) interface that supported television and capture applications use to access the tuner.

Key Features

• TV tuner recognition: Allows Windows to identify and communicate with the tuner component of a compatible Conexant-based card.
• WDM application support: Connects the hardware with software designed to work with WDM TV tuner devices.
• Tuning controls: Enables compatible applications to request channel and frequency changes, subject to the card’s capabilities and available broadcast signals.
• Integration with capture hardware: Works alongside any separate video-capture, audio, or crossbar drivers required by the complete TV card.

How to Install

1. Identify your hardware and Windows version. Open Device Manager and locate the tuner or unidentified multimedia device. Under Properties > Details, check its Hardware Ids. Also confirm whether your Windows installation is 32-bit or 64-bit.

1. Verify the driver package. Before downloading a Conexant BTTUNER TVision WDM TvTuner driver, check that its documentation matches your hardware ID and operating system. For Windows 11, 10, 8, or 7, compatibility depends on the specific package; a legacy WDM driver should not be assumed to support every listed version.

1. Extract and install the files. If the package includes an installer, run it and follow the prompts. Otherwise, extract the archive, right-click the device in Device Manager, choose Update driver, and select Browse my computer for drivers to locate the extracted folder.

1. Restart and check device status. Reboot if prompted, then return to Device Manager. Confirm that the tuner appears without a warning icon. If Windows rejects the driver as incompatible or unsigned, seek a supported package rather than disabling security protections.

1. Test with compatible TV software. Select the tuner in your application and configure the appropriate input and signal settings. If tuning works but video or audio is missing, check whether the card requires additional component drivers.

This is a TV tuner driver, not a graphics display driver. Installing it will not update your GPU or improve general graphics performance.

Common Issues and Fixes

• Install fails or rolls back: Use the correct 32/64-bit package for your Windows version. If setup stalls, disconnect the tuner, uninstall any existing Conexant TV tuner entries in Device Manager, reboot, then run the installer as administrator.
• Device not detected: Check that the BTTUNER TVision card is firmly seated and enabled in BIOS. In Device Manager, scan for hardware changes; if it appears with a warning, update the driver manually via “Browse my computer” and point to the extracted driver folder.
• Version conflicts: Remove older Conexant BTTUNER/WDM tuner drivers and related TV capture software before installing a new version. Avoid mixing drivers from different packages; reboot after uninstalling, then install one matching driver set and test in Device Manager.
