The ASUS P7H55 M audio driver helps Windows communicate with the motherboard’s onboard sound hardware, enabling playback through speakers or headphones and recording through a microphone. Installing a compatible driver can resolve missing audio devices, restore jack detection, and make supported sound settings available.

Key Features

• Onboard audio support: Enables Windows to use the motherboard’s built-in audio hardware for everyday listening, voice calls, and recording.
• Playback and recording controls: Provides access to supported speaker, headphone, microphone, and line-input settings.
• Audio jack functionality: Helps compatible audio software recognize connected devices and configure available inputs and outputs.
• Troubleshooting support: Can address problems caused by a missing, damaged, or incorrectly matched audio driver, including an unidentified multimedia device in Device Manager.

How to Install

1. Confirm your motherboard and Windows version. Check that your board is the ASUS P7H55 M, rather than a similarly named variant. Identify whether you are running Windows 11, 10, 8, or 7, and check your system type before choosing a package.

1. Check the driver’s compatibility notes. Download only a package that matches the onboard audio hardware and explicitly supports your operating system. This is an older motherboard, so official driver availability may differ between Windows versions; do not assume a Windows 7 package is supported on Windows 10 or Windows 11.

1. Prepare the installation files. Extract the download if it is compressed, and close applications that are using audio. Creating a restore point is a useful precaution before replacing an existing driver.

1. Run the installer. Open the setup program and follow its prompts. If the package has no installer but includes driver files, open Device Manager, select the audio device, choose Update driver, and browse to the extracted folder.

1. Restart and test your sound. Reboot if requested, then select the correct playback and recording devices in Windows sound settings. Test your speakers or headphones and microphone. If sound is still missing, check cable connections, volume levels, and whether onboard audio is enabled in the BIOS.

For Windows 11 or Windows 10, a driver offered through Windows Update may be an alternative when no suitable ASUS package is available. Audio-driver compatibility alone does not establish that the motherboard meets the operating system’s overall requirements.

Common Issues and Fixes

• Chipset/INF install fails or rolls back: The ASUS P7H55 M’s Intel H55-era packages may not support Windows 10/11. Run the installer as Administrator in Windows 7 compatibility mode, install Intel Chipset INF before LAN/audio/VGA drivers, then reboot.
• Onboard LAN or audio not detected: Confirm in BIOS that onboard HD Audio and LAN are enabled. Install the ASUS P7H55 M-specific Realtek/Intel packages rather than generic drivers, then rescan Device Manager.
• Version conflicts after Windows Update: Windows may replace ASUS drivers with generic ones. Use Device Manager to roll back the driver, reinstall the correct ASUS P7H55 M package, and avoid mixing Intel INF/MEI versions from other H55 boards.
