[Nils Ohlmeier [:drno]]

Assigning the default priority for intermittent test failure for now.

Paul can you please rate how important it is that the test hits this assertion even before starting (unfortunately Paul's status prevents NI during his PTO - but nobody else from the team has even touched this file::

Paul see comment #1: can you please have a look and verify the rating?

Comment 7

[Paul Adenot (:padenot)]

This means that a part of the graph thinks that we have audio flowing, whereas in fact, no audio has been written to the mixer.

This can be caused by the fact that something, an audio driver is forced, even if there is no audio track.

This code is becoming too complex, we should consider having a look and making it more simple. We need to touch it to fix the shutdown sequence anyways.

I don't believe this is a sec issue, it simply means no audio will be output, but that it's not expected: it breaks a graph invariant, that is, if an audio driver is present, there is at least a track that wants to output audio.

[Andreas Pehrson [:pehrsons] (PTO; back in Aug)]

I caught this one at a high failure rate recently (due to modified logging): https://treeherder.mozilla.org/#/jobs?repo=try&revision=d2f7b93656a5
On top of that this seems like a fix: https://treeherder.mozilla.org/#/jobs?repo=try&revision=0cfc1ddc844a

Hi Andreas, can you please request Beta approval on this when you get a chance (for 51, assuming that this won't get approved and landed before Monday's uplift)?

Bug 1292917 - Ended tracks should still keep the AudioCaptureStream going.

This approval request is for 51, whichever stage it might be in.

Approval Request Comment
[Feature/regressing bug #]: getUserMedia tab audio capture
[User impact if declined]: Intermittent assertions on try
[Describe test coverage new/current, TreeHerder]: this was caught by automation
[Risks and why]: Very low risk. On top of that it only affects a feature that is prefed off by default.
[String/UUID change made/needed]: None
