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 : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
