The ASUS Xonar DSX Audio Device driver connects your ASUS sound card to Windows, enabling audio playback, recording, and access to supported sound settings. Installing a compatible driver can help resolve missing audio devices, unavailable inputs or outputs, and problems caused by an incomplete installation.

Key Features

• Sound card recognition: Allows Windows to identify the ASUS Xonar DSX correctly and use its playback and recording capabilities.
• Playback and input support: Enables compatible speakers, headphones, microphones, and other connected audio equipment through the card’s available connections.
• Audio configuration: Depending on the driver package, provides access to settings such as speaker layout, volume levels, and supported audio effects.
• Reliable device communication: Supplies the software interface needed for applications and Windows to communicate with the sound card.

How to Install

1. Check your Windows version. Confirm whether your PC runs Windows 11, 10, 8, or 7, and check its system type. Choose a package explicitly compatible with your operating system and architecture; compatibility and available controls may vary between releases.

1. Download the matching driver. Verify that the package is intended for the ASUS Xonar DSX Audio Device, rather than another Xonar model. Save it to a convenient folder and extract the contents if it comes in a compressed archive.

1. Prepare for installation. Close games, media players, and other applications using audio. If you are replacing a problematic driver, follow the package’s instructions for removing the previous version before proceeding.

1. Run the installer. Open the setup program, approve the Windows permission prompt, and follow the on-screen instructions. If the package has no installer, use Device Manager, select the sound card, choose “Update driver,” and browse to the extracted driver folder.

1. Restart and test the sound card. Restart your PC when prompted, then open Windows sound settings and select the Xonar DSX as the playback device. Test your speakers or headphones and check the recording input if you use a microphone.

If audio remains unavailable, check the physical connections, mute settings, and selected output device before reinstalling. On systems with built-in motherboard audio, Windows may still be sending sound to a different device.

Common Issues and Fixes

• Install fails or rolls back: Run the ASUS Xonar DSX setup as administrator and try Windows 7/8 compatibility mode for older packages. Remove any previous Xonar driver first; if using a legacy unsigned driver, disable driver signature enforcement only for that install, then re-enable it.
• Device not detected: Reseat the DSX PCIe card, try another PCIe slot, and check Device Manager for an unknown/multimedia device. Disable onboard audio in BIOS and confirm the card is enabled.
• Version conflicts or dropouts: Uninstall old ASUS Xonar, C-Media, and Realtek audio drivers (delete driver files), reboot, then install the DSX package. Set Xonar DSX as default playback and disable unused onboard audio.
