High Definition Audio Updates Made Easy

If you thought high definition only applied to television sets, think again.

The computer is becoming more and more integrated with entertainment systems with users now streaming digital music from their PCs to the stereos as well as watching digital movies right on their laptops. Better computer speakers are capable of producing truer sounds – if the sound card can handle the sound quality demands that these new systems and their audiophile users are now demanding. High definition audio addresses these demands.

The Universal Audio Architecture (UAA) initiative standardizes class driver architecture for audio devices running under a Windows environment. This initiative addressed inconsistent support for audio and created standards for audio devices. It’s a complex system that attempts to ensure that audio devices will be able to handle the audio demands under Windows as well as provide copyright (Digital Rights Management) support on an audio I/O basis.

All computers that ship with Windows Vista must provide a high definition audio device driver (UAA-compliant device) that works properly without additional drivers in order to bear the Windows logo.

The UAA’s goals include better system performance and stability, easier installation of devices and audio drivers, glitch-free audio, improved content security (Digital Rights Management), reduced vendor-supplied device drivers, a reduced need for updating device drivers, and guaranteed basic audio support for devices that are compliant with UAA.

If you have a Windows Vista computer, then you have a sound card on board that complies with the High Definition Audio Device Drivers UAA initiative. For example, you may have a Realtek High Definition audio device installed on your computer. Just because your audio device complies with the UAA, doesn’t mean that it will necessarily work as designed. One of the UAA’s goals is to reduce the need for device driver updates. However, if your device isn’t working as expected, you may need to reinstall the high definition audio device driver.

Before doing so, create a System Restore point on your computer so that if anything goes wrong, you can restore your settings and device drivers to a working configuration. System Restore doesn’t affect your data – just your system settings such as system files and device drivers. To access the System Restore utility, go to the Windows Start button, choose All Programs, Accessories, System Tools, System Restore, and then follow the instructions.

To determine which high definition audio card drivers to download, you must first determine which high definition audio device you have on your system. Do this by checking the Windows Device Manager. Simply go to the Control Panel, choose System, choose Device Manager, and then click the plus sign next to Sound, Video, and Game Controllers. You should see the various devices listed below. Look for the device that has the words “high definition audio device” in the description.

How to Update High Definition Audio Device Drivers

Double-click the device and choose the Driver tab. For there, you can select Update Driver. If you already have an updated device driver, choose “Browse My Computer.” If not, select the other option which automatically searches for approved device drivers. Follow the prompts to install the high definition audio device driver.

You can also download the high definition audio device driver for your particular device by visiting the device’s manufacturer’s web page. Most manufacturers make their updates available for free download directly on their website. It’s important that you pay attention to details when doing so because it’s common for device drivers of this nature to be operating system specific.

If you don’t like the results after installing the new device driver, you can either rollback the driver using the Roll Back Driver button found in Device Manager’s Driver tab or you can go into System Restore and restore your system to a previous state.

High Definition Audio device drivers are capable of better sound ...

and have become more stable thanks to the UAA initiative. Unfortunately, they still run into errors from time to time requiring the updated high definition audio device drivers. While updates aren’t required as frequently thanks to standardization, the occasional update can correct unexpected results, improve errors, and increase system performance.
