Gigabyte GA 78LMT USB3 6.0 Driver

The Gigabyte GA-78LMT-USB3 6.0 audio driver links the motherboard’s onboard sound controller to Windows, making playback through speakers, headphones, and microphone input work correctly. This package is intended for Gigabyte Technology’s AM3+ board and restores sound support after a fresh Windows installation, driver corruption, or a board replacement. It covers Windows 11, Windows 10, Windows 8, and Windows 7 environments.

Key Features

• Restores onboard HD Audio output for the Gigabyte GA-78LMT-USB3 6.0 after system setup or driver failure.
• Enables front-panel headphone and microphone jack detection along with automatic jack retasking.
• Supports stereo playback, microphone recording, and multi-channel speaker configurations where available.
• Provides consistent audio behavior across Windows 11, Windows 10, Windows 8, and Windows 7.

How to Install

1. Save the audio driver package for the Gigabyte GA-78LMT-USB3 6.0 to a local folder and extract it if the file is compressed.
2. Open Device Manager and remove any existing audio device under “Sound, video and game controllers” to prevent conflicts, then restart if prompted.
3. Run the driver setup file as administrator. If no installer is present, use Device Manager to update the audio device and browse to the extracted folder.
4. Follow the installation wizard until it finishes, then restart the computer even if Windows does not ask for a reboot.
5. After restarting, open Sound settings in your version of Windows, choose the correct playback and recording device, and test speaker or headphone audio.

Common Issues and Fixes

• Driver install fails or rolls back: Run the Gigabyte rev. 6.0 package as administrator and try Windows 7/8.1 compatibility mode on newer Windows. Install the AMD 760G/SB710 chipset driver first, reboot, then install USB 3.0, audio, and LAN drivers.
• USB 3.0 ports or controller not detected: Check Device Manager for an unknown “Etron EJ168 USB 3.0 Host Controller.” Enable the USB 3.0 controller in BIOS, use the rear ports directly, and install the correct Etron USB 3.0 driver before rescanning hardware.
• Version conflicts: Don’t layer old Gigabyte/AMD chipset or USB 3.0 packages over newer Windows in-box drivers. Uninstall the previous driver, reboot, and install the package matching the GA-78LMT-USB3 6.0 revision; mixing packages can cause dropped USB 3.0 speeds or yellow-marked devices.
