Title: USB audio device is not recognized after startup in 16.04 Status in fwupdate-signed package in Ubuntu: Fix Released Status in fwupdate-signed source package in Xenial: Fix Released Status in fwupdate-signed source package in Yakkety: Fix Released Bug description: [Impact] High end USB audio devices don't work properly after fwupd is started from gnome-software. [Test case] Login to Ubuntu session and try to use a USB audio device. See if it works properly. If you are applying this upgrade and testing a regression it's important that the device isn't in a bad state to start. To guarantee this doesn't happen: 1) Apply the update 2) Power off your machine 3) Unplug device 4) Plug in device 5) Power on machine 6) Check if it works. [Regression Potential] This affects the DFU provider in Ubuntu. The fix is only made to that part of the fwupd stack. No firmware for DFU has been published to the LVFS yet, so this shouldn't have any regression risk to Ubuntu. [Original bug] Hi @all, I used the same USB audio device in all previous Ubuntu versions (Focusrite Scarlet 2i2). It is supposed to be class compliant and works an all distros flawless (even RPI2 and OSMC). After upgrading from 15.10 to 16.04 it stopped to work: after start-up it does not show up as an audio device at all (also not recognized by aplay -l). I can workaround this by unplugging it and plugging it in again after Ubuntu booted up (strangely 2 times unplug/re-plug). After 2nd time plugging it in again it shows up and works great without any further issues until next restart. Maybe worth to note that I recognized today that fwupd uses continuously 100% CPU load, so I just killed it today. My Hardware (Main-board/CPU) is a bit older (Intel E8400), so could probably be some compatibility issue... regards, Tobias ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.4.0-21.37-generic 4.4.6 Uname: Linux 4.4.0-21-generic i686 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC1D0p: tobias 1553 F...m pulseaudio /dev/snd/controlC1: tobias 1553 F.... pulseaudio /dev/snd/controlC0: tobias 1553 F.... pulseaudio /dev/snd/controlC2: tobias 1553 F.... pulseaudio CurrentDesktop: Unity Date: Sat Apr 23 20:09:04 2016 InstallationDate: Installed on 2015-09-19 (217 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release i386 (20150422) PackageArchitecture: all SourcePackage: alsa-driver UpgradeStatus: Upgraded to xenial on 2016-04-22 (0 days ago) dmi.bios.date: 09/30/2008 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 1238 dmi.board.asset.tag: To Be Filled By O.E.M. dmi.board.name: P5B-Deluxe dmi.board.vendor: ASUSTeK Computer INC. dmi.board.version: Rev 1.xx dmi.chassis.asset.tag: Asset-1234567890 dmi.chassis.type: 3 dmi.chassis.vendor: Chassis Manufacture dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr1238:bd09/30/2008:svnSystemmanufacturer:pnSystemProductName:pvrSystemVersion:rvnASUSTeKComputerINC.:rnP5B-Deluxe:rvrRev1.xx:cvnChassisManufacture:ct3:cvrChassisVersion: dmi.product.name: System Product Name dmi.product.version: System Version dmi.sys.vendor: System manufacturer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupdate-signed/+bug/1574079/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
