Microsoft HD Audio Pin Config Test Guidelines
Microsoft Releases HD Audio Pin Configuration Test Guidelines
Microsoft has released a paper entitled Microsoft HD Audio Pin Configuration Implementation Test Procedure Guidelines. The paper describes how to use a Microsoft-supplied pin configuration utility to generate and validate a set of verb tables which is embedded in the system BIOS.
The verb table describes the audio configuration of the system. If the verb table is configured incorrectly, the UAA HD Audio class driver will not function properly and the Windows Vista logo tests will fail.
The white paper is posted at

The development of a verb table is a complex process, and often requires close cooperation between the following development team members:
- Audio Architect
- BIOS engineer
- Audio Test Engineer
- WHQL Test Engineer
- Audio Software Lead
- Audio Schematic and Layout Design Engineer
The pin configuration verb table embedded into the BIOS describes the audio endpoints that will be exposed in Windows Vista when using the UAA class driver. It is rigorously tested by the Vista logo test suite.
