This is 100% reproducible for me on 2 sound hardwares (internal sound card and USB sound card). --- ApportVersion: 2.17.2-0ubuntu1.1 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC1D0p: tobias 1173 F...m pulseaudio /dev/snd/controlC1: tobias 1173 F.... pulseaudio /dev/snd/controlC0: tobias 1173 F.... pulseaudio /dev/snd/timer: tobias 1173 f.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 15.04 HibernationDevice: RESUME=UUID=10052815-dcd6-4bc3-92a9-6e0d17608236 InstallationDate: Installed on 2015-05-25 (47 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release i386 (20150422) MachineType: TOSHIBA Satellite Pro A100 NonfreeKernelModules: nvidia Package: linux (not installed) PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.19.0-22-generic root=UUID=2fa7face-9244-4946-945d-c5da6d4fcfc4 ro quiet splash ProcVersionSignature: Ubuntu 3.19.0-22.22-generic 3.19.8-ckt1 RelatedPackageVersions: linux-restricted-modules-3.19.0-22-generic N/A linux-backports-modules-3.19.0-22-generic N/A linux-firmware 1.143.1 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: vivid UdevLog: Error: [Errno 2] Datei oder Verzeichnis nicht gefunden: '/var/log/udev' Uname: Linux 3.19.0-22-generic i686 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 07/12/2007 dmi.bios.vendor: Phoenix Technologies LTD dmi.bios.version: 6.00 dmi.board.name: CAPELL VALLEY(NAPA) CRB dmi.board.vendor: Intel Corporation dmi.board.version: Not Applicable dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 1 dmi.chassis.vendor: No Enclosure dmi.chassis.version: N/A dmi.modalias: dmi:bvnPhoenixTechnologiesLTD:bvr6.00:bd07/12/2007:svnTOSHIBA:pnSatelliteProA100:pvrPSAASE-00H004GR:rvnIntelCorporation:rnCAPELLVALLEY(NAPA)CRB:rvrNotApplicable:cvnNoEnclosure:ct1:cvrN/A: dmi.product.name: Satellite Pro A100 dmi.product.version: PSAASE-00H004GR dmi.sys.vendor: TOSHIBA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1473649/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
