Ho @LX2035 Accordino to the logs, the endpoint argument is required for this test:

PYTHON_TEST | 2026-03-17 10:57:39.056498 | mobly.signals.TestFailure: Details=
PYTHON_TEST | 2026-03-17 10:57:39.057627 | The --endpoint flag is required for this test.

You can configure the endpoint in project config screen as bellow:

"test_parameters": {
      "endpoint": 1
    }

In addition, please follow the instructions in the '13. Matter Test Harness Cameras' section of the User Guide for camera testing.

Thank you for your reply. After modifying this, we can now test it normally. However, I still feel that there are some issues. Our device's audio source is 16k opus, single channel, but the sound cannot be played. On the other hand, the sound recorded from the browser can be played back on my end. Therefore, I suspect that the audio playback parameters here are written incorrectly. Could you please help confirm? Thank you!
