Status: UNCONFIRMED

(Firefox :: Tabbed Browser, defect)

Description

[684sigma]

I have a problem with Firefox Beta 52. It doesn't happen in Firefox ESR 45.
Sometimes when I enable sound in tab without sound, it displays audio indicator.
It happens unpredictably, however, I noticed one specific scenario when it happens

1. Open http://youtube.com/watch?v=ZGqhhx8cxMg
2. Disable sound in tab, then stop the video, then enable sound in tab

Result: Audio indicator appears
Expected: No sound indicator

I guess this is due to bug 1232357, you have to wait a few seconds before it will hide.

yes, it's by design, there is a fading time.

My bug is not about fading time. It's about audio indicator shown in tab that never produced sound

So design is: when user disables "mute" function in a tab, to show audio indicator to demonstrate that the tab was producing sound (when in fact it wasn't)? Pls confirm.

Google Chrome doesn't do this.

Try the "2. Disable sound in tab, then stop the video, *then waiting for at least 5 seconds*, then enable sound in tab", the issue still exists?

There is a delay.
If you quickly mute the tab, pause the video and demute the tab, the sound icon stays briefly visible (the delay is here) then disappears because the video has been paused (i.e. no sound).

First of all, I went back, because the same bug happens in Chrome, so comment 4 is wrong.

This is not what I did. The issue still exists.

- I did not do anything "quickly". I several times disabled "mute" feature in tab, and it showed me audio indicator, while no sound was present. I simply provided a reliable scenario for you to reproduce.
- The sound icon is visible for a long time, this is all that matters. Several times I disabled "mute" feature in tab, saw audio indicator, thought that video stream is still playing, just that exact part of the video produces very silent sound, so I scrolled tab strip away to work with other tabs, expecting some more sound to come from the tab. I haven't seen that the icon disappears, otherwise I would enable music in another tab.

My bug is not about any delay. When I disable "mute" feature in tab, it gives me the information "there's sound in this tab". I didn't want to get any irrelevant information, and asked the confirmation, whether current design involves giving the user the false information. I'm asking you the 2nd time, please confirm that or reopen the bug
(I can do it myself, but I'm not doing it, because there seems to be some misunderstanding)

As I said, I can't reproduce it. NI flag cleared.
