Audio Codec - Lullaby Test - Certification - Desktop

  • Article

This automated test verifies audio during power-state transitions. The test plays audio before, during, and after transitions into sleep and hibernate power states to verify the integrity of the audio pipeline.

Specifically, the test uses the Microsoft® DirectSound® and Wave APIs to play audio, calls Advanced Configuration and Power Interface (ACPI) functions to put the computer into a low-power state, and awakens the computer by using a wait able timer event. The test then verifies that audio still plays correctly.

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.

The test returns FAIL if it does not detect an audio device, if it cannot set the power state of the computer, or if the audio pipeline is in an inconsistent state. For specific information about failures, review the test results in the generated log file.

Depending on BIOS, the test might require user intervention. If BIOS does not support wake from sleep and wake from hibernate, you must bring the computer out of sleep states for the test to continue.
