It seems there is a problem about connection. Only one channel was recorded. @kalin, can anyone help me check DUT in chromeos15-audiobox5-host1? Thanks!

I can see the following from stainless
https://stainless.corp.google.com/search?view=matrix&row=build&col=hostname&first_date=2018-07-06&last_date=2018-07-10&suite=chameleon_audio_perbuild&test=audio_AudioBasicHeadphone&board=peach_pi&exclude_cts=false&exclude_not_run=true&exclude_non_release=true&exclude_au=true&exclude_acts=true&exclude_retried=true&exclude_non_production=true

Which build are you referring to?

In build 10863.0.0, we can see chromeos15-audiobox5-host1 failed but chromeos2-row10-rack10-host3 passed at https://cros-goldeneye.corp.google.com/chromeos/healthmonitoring/testDetails?milestone=69&daysBack=30&testName=audio_AudioBasicHeadphone&board=peach_pi

I think there are some problems on chromeos15-audiobox5-host1. However, this DUT can pass test sometimes. Like in 10858.0.0, the test passed first but failed next time.

Thanks yuhsuan@. The audioboI see the results on stainless are much limited to final run of the test, and would not report the pre-final attempts results.

The audio box setup uses the audio jack plugger to mechanically plug the audio jack. Thus we have seen audio jack being dirty or broken, audio port on DUT not detecting etc. problems.

We'll check on the cleanliness and will replace cable(or DUT) if needed.

This bug has an owner, thus, it's been triaged. Changing status to "assigned".
