Install the latest public release of Windows, the version 1803 and any up to date release of Firefox (60.0b16 here).

Actual results:

Multiple sound outputs are listed. The number is not related to the number of tabs.


Expected results:

Only one sound output should be listed.

Can confirm. Same build of FF

I'm on the slow lane of the windows insider preview program. 

Windows 10 Pro
Version: 1803
OS Build: 17134.1

You can see the effects of this problem by right cliking volume icon in the taskbar and selecting open volume mixer.

The same for Win 10 Pro Version 1709 and latest Firefox Nightly (61). Actually latest Nightly is even worse than latest release (59.0.3): with Nightly there are about 20 sliders while only 8 tabs opened, while with latest - about 10 sliders for the same 8 tabs.

Also it looks like Windows Server 2016 Version 1607 is not affected: with many tabs (40+) opened there is just one slider for the Firefox (latest - 59.0.3, not nightly).

Windows 10 Pro - 1803

I see this as well in Nightly and 60.0.1. It seems like Windows creates a volume slider for nearly every running process. But only in the new sound mixer. The old mixer doesn't have this amount of selection for me.

By comparison:

Microsoft Edge will create a mixer for every tab that has media in it.

Google Chrome will create a mixer for every tab that has media in it and give it the title of the source tab.

Chromium Based browsers all follow Chrome's lead.

Same problem. Is there a workaround other than deactivating multiple processes for Firefox (= setting browser.tabs.remote.autostart to False in about:config)?

Comment 6

[AngelOfDarkness]

There will be also multiple entries for Firefox in Windows 1803/1809 --> Preferences --> System --> Sound --> extended options.
But only one slider is active, the others are without any sound-function.

:jimm, 6 months have gone by since I set a NeedInfo flag for the assignee of bug 1358372, but he hasn't had a look at this. Any ideas to move this forward? In bug 1358372, comment 48, you said you still get multiple volume sliders, but don't know how to reproduce the issue. Does the STR below help?

STR:
In the Settings window, multiple entries are listed right off the bat:
1. Open Windows Settings → System → Sound → App volume and device preferences.

For the old volume mixer,
1. Open the Windows volume mixer from the taskbar icon.
2. In Firefox, open a YouTube channel's video listing page, e.g.
https://www.youtube.com/user/BadLipReading/videos
3. Ctrl+click a video to open it in a new tab, e.g.
https://www.youtube.com/watch?v=RKOZgQy8qrw
4. Switch to that tab. If the doorhanger prompt pops up, keep the "Remember…" option checked, then click "Allow".
5. Close that tab.
6. Ctrl+click another video to open it in a new tab, e.g.
https://www.youtube.com/watch?v=gCMw3AhWBkA
7. Switch to that tab.

Actual results:
There are 2 "Firefox Nightly" entries in the volume mixer.

Expected results:
1 "Firefox Nightly" entry in the volume mixer and "App volume and device preferences".

As note... the issue I'm reporting in 1500683 is that while the MIXER is LEFT OPEN, sliders are not being destroyed. If the volume mixer is closed and reopened the number of sliders is correct (at least as far as my observations went).

I'll find someone to take a look, thanks.

I can confirm this, exactly as you said.

I'll add that these sliders are remaining in volume mixer even after I close all instances of firefox.exe (confirmed with Process Explorer), no extensions enabled.
FWIW, if volume mixer was left open and showing sliders from Firefox after I closed Firefox, then the next time I open Firefox, one more more sliders are added to the (supposedly) orphaned sliders. It winds up creating many, many sliders, even if no tabs have any media activity.
Firefox v 66.0.1 (64-bit)
Windows 1809 17763.379
No extensions enabled

Good day all, I noticed the extra sliders for a while now. And since I have the SndVol menu open non stop I never considered it a session issue. Now I read this, I can confirm in Win 10 - 64bit, when reopening the window, doubles are gone.

Is this fixed on Nightly? bug 1430907 has been fixed.

I can no longer reproduce this based on the STR at comment 7 on Windows 10 1909. But I also can't reproduce it in my regular profile with Firefox 75, only in a brand new one.

[Jasper van Weerd]

Hey, I have no idea what an STR is,

But I can reproduce this bug very easy;

Just open Volume Mixer, open FF, close FF, open FF, then you get as shown.

Greetings.

Comment 14 asked if it's fixed in the latest Nightly, so please test that version.

Closing as a duplicate. If people can reproduce this in v76+ please open a new bug.
