while this is failing 21 times, keep in mind that this is only run during peak load once every 5th push, typically that means we are only seeing 25% of the possibly failures- I suspect the failure rate is 60-80 times in the last week if we ran this on every push.

This started up again on the 22nd, I just did some retriggers:
https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=linux x64 debug browser-chrome&tochange=6d631ae7ee675a4dff13cde60a8501191b3209ae&fromchange=1f6e4335dabb491e85ca1d89185a1e5d1ac04ca0&selectedJob=109019920

(most are bc3, but one instance is bc2)
Flags: needinfo?(alwu)
and the retriggers point out that bug 1374930 is the root cause!

:jw_wang, as you are the patch author of bug 1374930, can you get a quick resolution (this week) on fixing this intermittent which seems to be a side effect of one of the patches?
Flags: needinfo?(alwu) → needinfo?(jwwang)
I don't think this is a regression from bug 1374930:
1. bug 1374930 doesn't change audio channel code at all.
2. comment 1 indicates the issue went away without any fix.

So it is probably the code changes the timing to make it more likely to happen.

I added some logs for debugging:

https://hg.mozilla.org/try/rev/fa0162688950667449d6ddefc37562672dd83f86

JWW -- test 1
JWW Play(ErrorResult& aRv) mAudioChannelWrapper=0x7fe82b69c900
JWW IsTabActivated() ShouldBlockMedia=0
JWW IsPlaybackBlocked() IsTabActivated()
JWW PlayInternal()
JWW -- test 2

We should check why mAudioChannelAgent->ShouldBlockMedia() (which is expected to return true in this test) returns false in IsTabActivated().

Will check it later.

I don't see any occurrences of this failure on Beta for Fx55, but given the patch that landed, I figured I would at least check as to whether we want to let this ride the 56 train or nominate it for Beta approval for 55.

Since this failure was triggered by bug1374930 which was only landed on FF56, I think we don't need to uplift this change to FF55.
