Why is my System Failing Windows 7 Audio Logo Tests?
The audio logo tests have been updated and expanded for Windows 7, and many of the older tests that were no longer meaningful were removed from the test suite. New tests have been added which focus on achieving the best possible audio experience in Windows 7. These include tests for compliance with the Intel High Definition Audio 1.0 interface standard, as well as compliance with Unified Audio Architecture (UAA) hardware design requirements.
First of all, you must have the Driver Test Manager (DTM) set up properly, including an Audio Precision System 2 test set for labs which will be running the new audio fidelity tests. Optimal Sound provides training on setting up and validating the DTM with an Audio Precision Test set.
If your system is failing the pin configuration test, UAATEST.EXE, or if the class driver is producing a Code 10 error when it tries to load, then your system has an incorrect pin configuration.
Optimal Sound provides turnkey development service for pin configuration verb tables. Optimal Sound also provides training for your entire team on how to develop verb tables. Developing pin configuration verb tables is one of the new audio development steps in Windows Vista.
If you are not able to develop a verb table which will pass logo, then your system may not be UAA compliant. Optimal Sound provides schematic and layout review services.
Another likely point of failure are the audio fidelity tests. In some cases, the failures may be due to excessive noises induced by other components in the computer and coupled into the audio subsystem. Fixes to these types of failures often require changes to the layout of the motherboard, which is costly and time-consuming.
Use Optimal Sound to add an audio expert to your team, ensuring that your systems are easy to understand, functioning properly with Windows 7 and, of course, sounding great. Contact us for more info.
