I have a problem with Firefox Beta 52. It doesn't happen in Firefox ESR 45. Sometimes audio indicator disappears if page has sound, when I unmute tab (Ctrl+M). It happens unpredictably, however, I noticed one specific scenario when it happens 1. Open http://lagged.com/play/352/ , wait until advertisement finishes 2. Enable sound in the game 3. Mute tab, disable sound in the game, enable sound in the game, unmute tab Result: No audio indicator in tab Expected: Audio indicator in tab Other examples http://lagged.com/play/352/ http://lagged.com/play/535/ http://lagged.com/play/571/
Keywords: regression
Another bug happens on all examples above, filed as bug 1346880.
Regression range: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=32dcdde1fc64fc39a9065dc4218265dbc727673f&tochange=27dade5e0c8350189eeb6495d70a9fb25ce137a9 Suspect: ede7e1b58095 Alastor Wu — Bug 1192818 - part2 : only dispatch DOMAudioPlaybackStarted when there is audible sound. r=baku Reporter, I can't reproduce this problem in 52.0 & 52.0esr, please confirm again.
Status: UNCONFIRMED → NEW
Has Regression Range: --- → yes
Has STR: --- → yes
Ever confirmed: true
Summary: Audio indicator disappears after unmuting tab if page has sound (sometimes) → Audio indicator disappears after unmuting tab if Flash regain sound
Version: 52 Branch → 53 Branch
Yes, there was a mistake in the first comment, because I have 2 versions of Beta. Sorry. It doesn't happen in Firefox Beta 52, it was found in Firefox Beta 53.
[Tracking Requested - why for this release]: user-visible regression to a visible control. Makes it impossible to mute a tab.

Track 53+ as user-visible regression.
It is an html5 game drawn on <canvas>, and it doesn't use <audio> or <video>, it uses Web Audio https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API
Summary: Audio indicator disappears after unmuting tab if Flash regain sound → Audio indicator disappears after unmuting tab if an html5 page regains sound
An easier way to reproduce the bug: 1. Open https://mdn.github.io/webaudio-examples/decode-audio-data/ 2. Execute attached JavaScript code 3. Click "Play" button on the page. When audio starts, click "Reconnect" button on the page. 4. Mute tab, click "Mute" button on the page, click "Unmute" button on the page, unmute tab.
Can you reproduce this? Can we get it fixed in 53?
Flags: needinfo?(alwu)
Sure, I'm working on it now.

So the only case |mAudible| would be non-audible is when web audio is muted or suspended. How do you think? Thanks! [1] https://goo.gl/ABmwP2

Approval Request Comment [Feature/Bug causing the regression]: Regression by bug1192818. [User impact if declined]: The sound indicator couldn't display correctly [Is this code covered by automated tests?]: Yes [Has the fix been verified in Nightly?]: Yes [Needs manual test from QE? If yes, steps to reproduce]: No [List of other uplifts needed for the feature/fix]: No [Is the change risky?]: No [Why is the change risky/not risky?]: Won't affect the normal playback and it can make sound indicator showing correctly [String changes made/needed]: No

This seems like an ideal thing for manual testing since we have steps to reproduce it. Also, seems like a good idea to verify the fix, it doesn't seem trivial glancing over the code or from the discussion in this bug!

Comment on attachment 8853290 [details] [diff] [review] Bug 1346872 - notify audible state change for webaudio and NPAPI. (aurora-beta) This seems a bit risky to uplift late in beta (heading into beta 9, a week from the RC build) But since it is a regression from 53, it would be nice not to ship it to release. Andrei- can your team verify this once it lands in beta 9? Thanks.

had to back this out from beta and aurora for test failures like https://treeherder.mozilla.org/logviewer.html#?job_id=88264348&repo=mozilla-aurora

What if, instead, we back out the work from bug 1192818? With that removed, does the audio indicator work as expected ? Either way, we should aim to fix this for beta 10 later this week.

Alastor, Dão, what do you think about backing out bug 1192818 rather than landing this on beta 10?

I have reproduced this issue using Firefox 53.0b1 (2017.03.07) on Win 8.1 x64. I can confirm this issue is fixed, I verified using Firefox 55.0a1 on Win 8.1 x64, Mac OS X 10.11 and Ubuntu 16.04 x64.

Can confirm that bug 1192818 backs out cleanly from Beta. Just say the word :)
Gerry, this may still be a problem in 54.

Alastor, How should we do for 54? Still backout Bug 1192818?

I can confirm this issue is fixed, I verified using Firefox 53.0b10 on Win 8.1 x64, Mac OS X 10.11 and Ubuntu 14.04 x64.
We can also backout the bug 1192818 in 54.
