While tracking down the cause of test failures from the patch in Bug 1149930, it seems that the <audio> element cannot play OGG or MP3 files on Treeherder in the Gaia integration tests for Music. This does not reproduce when running marionette-js locally on Linux unless you specify the `PULSE_AUDIO=":"` flag. If you run the Gaia integration tests for Music with the `PULSE_AUDIO=":"` flag on a local Linux machine, the exact same test failures are reported as on Treeherder. The only thing the patch in Bug 1149930 does is listens for the 'error' event on the <audio> element and skips ahead to the next song in the queue if it is encountered. When running on Linux with the `PULSE_AUDIO=":"` flag, the 'error' event is thrown for every song played which causes unpredictable state in the integration tests.

Treeherder is a dashboard for displaying results. It has nothing to do with how said results were created :). Moving this over to the Taskcluster product since it sounds like a machine config issue.

See gaia try run here: https://treeherder.mozilla.org/#/jobs?repo=gaia&author=nullaus@github.taskcluster.net Things looking really good. Will remove :justindarc's commit before pushing.

What did you change? I recently discovered in bug 1214809 that pulseaudio doesn't actually start in the taskcluster/tester image. Did you do something to fix that?

Will remove :justindarc's commit before pushing. Actually, still really broken. Trying some other avenues now.

Any update here?

These tests are running as root, correct? If not, I discovered in bug 1214809 that using 'su' to drop root privileges causes pulseaudio to crash docker, and 'sudo -E -u worker' works a lot better.

Marking it a P1 as it blocks a P1 bug for 2.5+

Any update on this?

Sorry Justin, I'm completely swamped, I currently have no idea when I'll get to this.
