Public bug reported: After recent update to linux-image-3.19.0-21-generic, sound volume control keys stopped working. It kind of works, I still can assign them in System Settings -> Keyboard -> Shortcuts, but it does not control sound volume.
xev output shows correct keybindings: $ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p' keycode 36 = (keysym 0xff0d, Return), state = 0x0 keycode 123 = (keysym 0x1008ff13, XF86AudioRaiseVolume), state = 0x0 keycode 122 = (keysym 0x1008ff11, XF86AudioLowerVolume), state = 0x0 ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: alsa-base 1.0.25+dfsg-0ubuntu4 ProcVersionSignature: Ubuntu 3.19.0-21.21-generic 3.19.8 Uname: Linux 3.19.0-21-generic i686 ApportVersion: 2.17.2-0ubuntu1.1 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: egoisto 3581 F.... pulseaudio CurrentDesktop: Unity Date: Mon Jun 29 23:25:25 2015 InstallationDate: Installed on 2011-12-21 (1285 days ago) InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_Card: Built-in Audio - HDA Intel PCH Symptom_Jack: Speaker, Internal Symptom_Type: Volume slider, or mixer problems Title: [Aspire V5-572G, Realtek ALC282, Speaker, Internal] volume slider problem UpgradeStatus: Upgraded to vivid on 2015-05-10 (50 days ago) dmi.bios.date: 05/22/2013 dmi.bios.vendor: Insyde Corp. dmi.bios.version: V2.06 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: Dazzle_CX dmi.board.vendor: Acer dmi.board.version: Type2 - A01 Board Version dmi.chassis.type: 10 dmi.chassis.vendor: Chassis Manufacturer dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsydeCorp.:bvrV2.06:bd05/22/2013:svnAcer:pnAspireV5-572G:pvrV2.06:rvnAcer:rnDazzle_CX:rvrType2-A01BoardVersion:cvnChassisManufacturer:ct10:cvrChassisVersion: dmi.product.name: Aspire V5-572G dmi.product.version: V2.06 dmi.sys.vendor: Acer ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 vivid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1469837 Title: [Aspire V5-572G, Realtek ALC282] sound volume control keys stopped working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1469837/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
