Necessary driver for the High Definition Audio bus. Without it, programs such as 'SoundMAX' will not load.

This driver is on the High Definition Audio Bus and is essential to the Front Panel Audio operatation. If the front panel audio is improperly configured (ie. the wrong dongled pins are coneccted to the motherboard or the incorrect pci video device driver is installed then the hdaudbus.sys driver will cause problems when an audio jack is plugged into the front or rear jack). Setting bios to AC97 prevents BSOD when plugging into front jack but does not eliminate error when plugging into rear HD Jack. BSOD suggests disabling video adapter since driver is installed when video driver is install

This message is harmless- hd (high definition) aud (audio) bus (silver track on MB leads to 7.1-5.1 audio back panel). MoBo P5N-D at XP32pro startup, found new hardware "microsoft UAA cabinet file is needed" linked to Win OS. It's just asking for drivers for High Definition operation. Do you need HD operating? Plug in your SPDIF/ FibOpt or go to [http://support.microsoft.com/kb/888111 ] to request hot fix driver to be emailed to you to solve the UAA/hdaudbus issue either from popping up at startup or no audio sound.
