Actually, I just realized this bug is likely fixed by:
https://lists.freedesktop.org/archives/igt-dev/2019-June/014453.html

I had similar logs when testing locally (the test saying the flatline is detected but failing).

    tests/kms_chamelium: fix read from uninitialized value in flatline audio test
    
    streak isn't initialized, which makes the test fail in the case in which it's
    not zero by chance. This bug has been seen in production™.

  No new failures caught with the new filter

The new failures seem like a different bug. It seems that DP audio tests are starting to pass instead of hitting the IsAudioStable issue. The fact that logs are truncated make it very difficult to understand what's going on.

Hopefully dynamic subtests will be able to help a little.

Should a new bug be opened?
