The Acer C720 audio driver lets Windows communicate with the laptop’s sound hardware, enabling playback through its speakers and headphone connection. If your Acer C720 has missing sound or an unrecognized audio device after a Windows installation, a compatible driver may help restore normal operation.

Key Features

• Audio hardware recognition: Helps Windows identify the onboard audio device instead of leaving it listed as an unknown device in Device Manager.
• Speaker and headphone playback: Provides the software connection needed to send sound to supported audio outputs.
• Recording support: Enables microphone input where supported by the hardware and driver package.
• Windows sound integration: Makes supported playback and recording devices available through Windows audio settings for volume adjustment, device selection, and testing.

How to Install

1. Check your Windows version and hardware. Confirm whether you are running Windows 11, 10, 8, or 7, along with the system architecture. In Device Manager, check the audio device’s hardware IDs if you need to distinguish between available packages.
2. Verify the driver’s compatibility. Choose a package that explicitly matches your Acer C720 audio hardware and installed Windows version. The C720 was originally designed as a Chromebook, so Windows audio support may depend on community-developed drivers and additional platform components rather than an official Acer Windows package.
3. Prepare and extract the download. Create a restore point if System Protection is enabled, then extract the driver archive if necessary. Review any included instructions for prerequisites.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the relevant audio device, and select Update driver. Choose the option to browse your computer and point it to the extracted driver folder.
5. Restart and test sound. Select the intended output in Windows sound settings, play an audio sample, and test headphones and microphone input if available.

If sound remains unavailable, check for muted outputs and unresolved devices in Device Manager before trying another package. A driver intended for one Windows release is not automatically compatible with the others.

Common Issues and Fixes

• Install fails with Code 10/28 or “unsupported hardware”: confirm 64-bit Windows and correct legacy/custom UEFI boot for the C720 Chromebook; run the Acer/Intel chipset installer as administrator and disable Secure Boot only if required.
• Touchpad, keyboard, Wi-Fi, or audio not detected: install the Intel chipset/Serial IO package first, then the specific C720 module driver; check Device Manager for hidden/unknown devices and avoid generic Windows drivers for Chromebook hardware.
• Version conflicts after Windows Update: uninstall the old driver and delete its driver package, reboot, then install the matching Acer C720 Windows version; don’t mix 32/64-bit or Windows 10/11 packages, and use Device Manager rollback if a device breaks.
