This is intermittent because the previous cycle from the same changeset <http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1244269414.1244275060.11272.gz> did not show this failure.

I can reproduce this fairly consistently in a Vista VM with sound disabled.  Open the test in the browser, open Task Manager and position it over the browser window, start the test, quickly minimize and restore Task Manager by clicking on it in the task bar.

It probably relies on having the window animations enabled--it looks like the minimize/maximize animations cause the browser's event queue to starve for half a second or more each time.

Same test, different failure mode:
http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1246965117.1246969572.12417.gz
OS X 10.5.2 mozilla-central unit test on 2009/07/07 04:11:57  

ERROR TEST-UNEXPECTED-FAIL | /tests/content/media/test/test_bug468190_wav.html | Expect at least one playing event

Looks like in this case, the test somehow didn't get any onplaying events, but got the onfinished.
