Conexant 2388x AVStream Crossbar (Blackbird - Dual Input) Driver

The Conexant 2388x AVStream Crossbar (Blackbird – Dual Input) driver helps Windows and compatible capture software route audio/video signals between the inputs on supported Conexant-based capture hardware. You may need it after reinstalling Windows, when a crossbar component appears as an unknown device, or when your capture application cannot select the correct input.

Key Features

• Input routing: Provides the crossbar interface used by compatible software to select available audio/video input paths.
• AVStream integration: Works as part of the capture device’s driver stack, helping Windows applications communicate with supported hardware.
• Dual-input support: Exposes input-routing options for compatible Blackbird dual-input hardware; available controls depend on the board and capture application.
• Legacy Windows coverage: Packages may support Windows 10, 8.1, 7, Vista, and XP. Check the individual package’s operating-system and architecture requirements before downloading.

How to Install Conexant 2388x AVStream Crossbar (Blackbird – Dual Input) Driver

1. Identify your hardware. Open Device Manager and locate the capture device or unrecognized component. Check Properties > Details > Hardware Ids, and note the capture card’s manufacturer and model. A matching Conexant chipset name alone does not guarantee compatibility.
2. Choose a matching package. Before starting your Conexant 2388x AVStream Crossbar (Blackbird – Dual Input) driver download for Windows, confirm that the package supports your hardware ID, Windows release, and 32-bit or 64-bit architecture. For Windows 10/11 systems, note that Windows 11 support is not established by the listed compatibility information.
3. Download and prepare. Select a trusted free download, preferably supplied by the capture-card manufacturer. Extract the archive if necessary, and create a restore point before replacing an existing driver.
4. Install the driver. Run the supplied installer and follow its instructions. If the package provides INF files instead, use Device Manager > Update driver > Browse my computer for drivers, then select the extracted folder. The crossbar component may install with the full capture-card driver package.
5. Restart and test. Restart Windows if prompted, then open your capture application. Confirm that the intended input is available and that audio/video routing works correctly.

Keep the driver updated when a compatible release addresses a problem or improves stability. The latest version is useful only if it matches your specific capture hardware and Windows installation; review compatibility notes before each update, and retain a working package in case you need to roll back.
