Some tests like audio_AudioBasicHeadphone should run on device with label test_audiojack.

But it seems that the following test on device 'link' in R67,
audio_AudioBasicHeadphone ran on the one without the label:

then we'll see tests failed on the device

When I looked into the dashboard,
I found that most of the failed tests on link are all b/c the wrong schedule settings. Please check the link below.

We need someone to fixed the test schedule settings.
Thanks!
