Audio Codec - AC3 Test - Certification - Desktop

  • Article

This automated test verifies that audio devices that support the AC-3 format comply with Windows requirements.

This test makes sure that each enumerated KSCATEGORY_AUDIO and KSCATEGORY_RENDER filter that exposes AC-3 format pins complies with the Microsoft Driver Development Kit documentation that is related to implementing AC-3 format pins. Also, this test makes sure that the filter does not prevent support for AC-3 streaming through the Wave and Microsoft DirectSound APIs.

Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: Audio Device Testing Prerequisites.

Troubleshooting

For generic troubleshooting of HLK test failures, see Troubleshooting Windows HLK Test Failures.

For troubleshooting information, see Troubleshooting Audio Testing.

All test cases return PASS or FAIL. To review test details, review the test log from Windows Hardware Lab Kit (Windows HLK) Studio. The test might return SKIP, which you should consider to be PASS for the overall test if no AC-3-compatible devices are present on the system. If the test does not detect AC-3 devices and the hardware does support them, a problem exists with the way that the pin in the filter of the specific device advertises itself.
