KS Position Test

This automated test verifies that an audio device and driver accurately implement audio render position for stream synchronization.

This test requires that an audio device and driver are installed on a test system. The test targets the audio device and calls GetPosition on the kernel-streaming (KS) filter to make sure that the position is reported accurately.

The following table shows the details for this test.
