HD Audio is an end-to-end audio specification that defines the controller, link and board implementation of audio and modem hardware, both of which are required and operate on the same bus. It enables high-quality, home theater-like sound on multimedia/Media Center PCs.

It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed a wrong driver. Problems can arise when your hardware device is too old or not supported any longer.
