The ASUS Xonar DX Audio Device driver enables Windows to communicate with your ASUS sound card for audio playback and recording. Installing the appropriate driver helps restore missing sound, recognize the card correctly, and make its audio controls available. For Windows 11, 10, 8, or 7, check the individual driver package’s compatibility before downloading, as support can vary by release.

Key Features

• Sound card detection: Allows Windows and audio applications to recognize the Xonar DX and use its playback and recording connections.
• Multichannel audio configuration: Provides access to supported speaker layouts, including surround sound, when used with compatible speakers and content.
• Playback and recording controls: Enables settings for output levels, input selection, and other supported audio options through Windows or the included ASUS audio utility.
• Device-specific functionality: Supplies the software needed to use the card’s supported audio processing features, with available controls depending on the driver package.

How to Install

1. Check your Windows version. Confirm whether your computer runs Windows 11, 10, 8, or 7, and whether it uses a 32-bit or 64-bit system. Select a package that explicitly lists compatibility with your configuration and the ASUS Xonar DX Audio Device.

1. Download and extract the driver. Save the installation package to a convenient folder. If it comes as a compressed archive, extract its contents before running setup. Review any included instructions for prerequisites or compatibility limitations.

1. Prepare for installation. Close audio players, games, and recording software. If you are replacing a problematic driver, follow the package’s guidance on removing the previous version first; avoid uninstalling unrelated audio devices.

1. Run the installer. Launch the setup program and approve the administrator prompt if requested. Follow the on-screen instructions, then restart Windows when prompted. If no installer is supplied, use Device Manager to update the sound card’s driver from the extracted folder.

1. Select and test the output. Open Windows sound settings and choose the Xonar DX as your playback device. Check the speaker configuration, play a test sound, and verify microphone or line-in recording if needed. If there is no audio, confirm the cable connections and output selection before reinstalling.

Common Issues and Fixes

• Installer fails or rolls back: Run the ASUS setup as administrator, temporarily disable antivirus, and use the package matching your Windows version. Remove existing Xonar/C-Media audio drivers in Device Manager, reboot, then reinstall.
• Card not detected: Power off, reseat the Xonar DX in its PCIe slot, and check Device Manager under Sound, video and game controllers. Disable onboard audio in BIOS if it takes priority; try another PCIe slot if needed.
• Version conflicts or no sound after update: Uninstall old ASUS Xonar and C-Media components, reboot, and install only one driver version. Avoid mixing Windows Update audio drivers with the ASUS package; roll back in Device Manager if playback breaks.
