Public bug reported: Sudden absence of a audio output device(s) after updates or misconfiguration is a quite popular error in many Ubuntu versions. The sound configuration panel in unity doesn't offer any support to automatically detect sound hardware and install necessary drivers. I'd be nice if it did including the following functions:
- Selection of backend. There's `alsa` and `jack` and possibly more and no reason to bother Ubuntu users with that except for one page in a guided dialog. - Auto-detection of hardware. Although non-deterministic because of "cheap" hardware which doesn't identify itself correctly as audio hardware, there should be a page in a guided dialog allowing selection for correctly identified hardware (including eventual workarounds for detection). - detection of necessary drivers and support for choice if there's more than one available ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: unity 7.4.0+16.04.20160415-0ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-22.39-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 NonfreeKernelModules: openafs .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 CompizPlugins: »/apps/compiz-1/general/screen0/options/active_plugins« wurde kein Wert zugewiesen CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Tue May 17 13:29:30 2016 DistUpgraded: 2016-03-14 15:43:39,246 DEBUG enabling apt cron job DistroCodename: xenial DistroVariant: ubuntu DkmsStatus: bbswitch, 0.8, 4.4.0-22-generic, x86_64: installed openafs, 1.6.15, 4.4.0-22-generic, x86_64: installed vboxhost, 5.0.20, 4.4.0-22-generic, x86_64: installed GraphicsCard: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo 3rd Gen Core processor Graphics Controller [17aa:3904] InstallationDate: Installed on 2015-12-12 (156 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Release amd64 (20151021) MachineType: LENOVO 20221 ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.4.0-22-generic root=UUID=791b47e7-915d-4d5a-bce0-d7e9b660a2ab ro rootflags=subvol=ubuntu-main-root SourcePackage: unity UpgradeStatus: Upgraded to xenial on 2016-03-14 (63 days ago) dmi.bios.date: 07/12/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 71CN51WW(V1.21) dmi.board.asset.tag: No Asset Tag dmi.board.name: INVALID dmi.board.vendor: LENOVO dmi.board.version: 31900003WIN8 STD MLT dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo IdeaPad Z500 Touch dmi.modalias: dmi:bvnLENOVO:bvr71CN51WW(V1.21):bd07/12/2013:svnLENOVO:pn20221:pvrLenovoIdeaPadZ500Touch:rvnLENOVO:rnINVALID:rvr31900003WIN8STDMLT:cvnLENOVO:ct10:cvrLenovoIdeaPadZ500Touch: dmi.product.name: 20221 dmi.product.version: Lenovo IdeaPad Z500 Touch dmi.sys.vendor: LENOVO upstart.unity-panel-service-lockscreen.log: (unity-panel-service:31881): GLib-CRITICAL **: Source ID 4294967295 was not found when attempting to remove it (unity-panel-service:5623): GLib-CRITICAL **: Source ID 4294967295 was not found when attempting to remove it version.compiz: compiz 1:0.9.12.2+16.04.20160415-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.67-1 version.libgl1-mesa-dri: libgl1-mesa-dri 11.2.0-1ubuntu2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.2.0-1ubuntu2 version.xserver-xorg-core: xserver-xorg-core 2:1.18.3-1ubuntu2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.1-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-1build2 xserver.bootTime: Tue May 17 12:10:01 2016 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 5557 vendor CMN xserver.version: 2:1.18.3-1ubuntu2 ** Affects: unity (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug compiz-0.9 ubuntu xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1582670 Title: Add auto-detect and -installation routine to sound configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1582670/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
