Meanwhile (new Kubuntu 14 installation & FF 51) I'm back where I began. The workaround with the "media.volume_scale" used to work, but now no more.
Every time I switch in FF to another video stream, volume is switched to 0%. Interestingly this does not happen, when I let the video play until the end. I even can jump through the video but I may not loose focus of the video tab but I may loose focus of the window. All other audio controls remain stable where I left them the last time. So now I just tried to play around with this setting and found out that – now – any value above 1.0 will kill the sound when switching to another video stream or loosing tab's focus. Setting any value blow or equal to 1.0 will reset the volume this value on switching. If I do not loose the videos focus (I guess, that's the point of it) the volume remains where it was set before and even through restarting FF or Kubuntu. So, this problem is a real paint is the a… !!! Could please someone fix that? Or does anyone have a better workaround? Or a better browser without loosing all those fine addons I got used to?

Only on one of these machines I had the problem, that I did not hear sound when playing videos with firefox, although the sound on that machine works (e.g. when watchting the same videos with mplayer from command line.) Which caused me a lot of headache and debugging time. I'fe finally found the problem. I need to use pavucontrol or pacmd , then identify the input stream from firefox (a firefox logo and named as CubebUtils , and set the volume from 0 to 100% or do something like pacmd set-sink-input-volume 1 65535 where 1 is the input number determined with e.g. pacmd list So it seems as if the sound driver of firefox lacks a proper volume setting, which might not cause any problems with most sound cards, however, my sound card (or it's driver) has a volume of 0. % lspci | fgrep Audio 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) regards ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: firefox 34.0+build2-0ubuntu0.14.04.1 ProcVersionSignature: Ubuntu 3.13.0-43.72-generic 3.13.11.11 Uname: Linux 3.13.0-43-generic x86_64 NonfreeKernelModules: zfs zunicode zavl zcommon znvpair AddonCompatCheckDisabled: False ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: hadmut 3307 F.... panel-12-mixer hadmut 3316 F.... pulseaudio /dev/snd/pcmC0D0p: hadmut 3316 F...m pulseaudio BuildID: 20141127111021 CRDA: Error: [Errno 2] Datei oder Verzeichnis nicht gefunden: 'iw' Channel: Unavailable CurrentDesktop: XFCE Date: Thu Dec 18 16:54:17 2014 Extensions: extensions.sqlite corrupt or missing ForcedLayersAccel: False IncompatibleExtensions: Unavailable (corrupt or non-existant compatibility.ini or extensions.sqlite) InstallationDate: Installed on 2014-08-06 (133 days ago) InstallationMedia: Ubuntu-Server 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.3) IpRoute: default via 192.168.164.1 dev p5p1 169.254.0.0/16 dev p5p1 scope link metric 1000 192.168.164.0/24 dev p5p1 proto kernel scope link src 192.168.164.100 192.168.200.0/24 dev vlan0 proto kernel scope link src 192.168.200.1 Locales: extensions.sqlite corrupt or missing Plugins: Windows Media Player Plug-in - /usr/lib/mozilla/plugins/gecko-mediaplayer-wmp.so (gecko-mediaplayer) RealPlayer 9 - /usr/lib/mozilla/plugins/gecko-mediaplayer-rm.so (gecko-mediaplayer) QuickTime Plug-in 7.6.9 - /usr/lib/mozilla/plugins/gecko-mediaplayer-qt.so (gecko-mediaplayer) DivX Browser Plug-In - /usr/lib/mozilla/plugins/gecko-mediaplayer-dvx.so (gecko-mediaplayer) mplayerplug-in is now gecko-mediaplayer 1.0.8 - /usr/lib/mozilla/plugins/gecko-mediaplayer.so (gecko-mediaplayer) PrefSources: prefs.js Profiles: Profile0 (Default) - LastVersion=34.0/20141127111021 (In use) RelatedPackageVersions: gecko-mediaplayer 1.0.8-4ubuntu1 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no RunningIncompatibleAddons: False SourcePackage: firefox Themes: extensions.sqlite corrupt or missing UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/12/2012 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: H61TIW08.111 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: H61H2-TI2 dmi.board.vendor: Medion dmi.board.version: 1.0 dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 3 dmi.chassis.vendor: Medion dmi.chassis.version: 1.0 dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrH61TIW08.111:bd10/12/2012:svnMedion:pnG24:pvr1.0:rvnMedion:rnH61H2-TI2:rvr1.0:cvnMedion:ct3:cvr1.0: dmi.product.name: G24 dmi.product.version: 1.0 dmi.sys.vendor: Medion To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1403938/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
