It looks like link is the device that mostly fails both tests audio_AudioBasicUSBPlayback and audio_AudioBasicUSBRecord

7 days view - https://screenshot.googleplex.com/gHw6nSmphxq

If we change the view for board link and present the host name, we see
https://screenshot.googleplex.com/nX8OnX9MKSD
that host chromeos2-row10-rack5-host11 is at fault, while the host chromeos15-audiobox4-host2(in audio box)works fine.

Host chromeos2-row10-rack5-host11 could be consistently failing b/c:
- unplugged USB cable, or bad chameleon (FPGA)
- by some reason the all time plugged audio jack setup for chameleon is affecting the USB connection

To find out
1) Will check on USB cable plugged status
2) will re-direct the perbuild tests to the another host in Atlantis(chromeos2)
3) will unplug audio jack and re-run the test.

Sridhar, please go over these checks.

Summary: [Test bed ]audio_AudioBasicUSBPlayback: TestFail: Wrong output node(s) selected ['HEADPHONE'] expected: ['USB'] (was: audio_AudioBasicUSBPlayback: TestFail: Wrong output node(s) selected ['HEADPHONE'] expected: ['USB'])

The USB tests on the nightly suite show chromeos2-row10-rack5-host13 does not have this issue. So I guess it is more of a specific host problem.

I guess 1) will resolve the issue.

USB connection issue (Bad cable).
Replacing USB cable fixed this issue.

Thanks Sridhar for fixing the test bed.
