** Description changed: I noticed when i restarted my laptop (HP 630 after installing the latest stable linux kernel (linux-image-13.110.13-generic:amd64 13.11.0-13.20), there was no sound, i could not connect to the internet via either cable or wireless and the graphics was slow. On further inspection i found out no network manager displayed "network devices available" and there was a dummy output in sound settings. After searching the internet i came across this link ---> http://askubuntu.com/questions/294016/no-sound-in-ubuntu-13-04-only-dummy-output-device-listed After following the instruction and choosing an earlier version of kernel (3.11.0-12-generic), all the issues were resolved. I have ubuntu 13.10 installed. Below is the comment that helped. Hope this is helpful in some way to deal with the issue with the latest kernel. "I also had it - Does sound work before reboot after one update? If yes it is probably the same. It's bug related to kernel 3.8.0-18. Run uname -r to check your version of Kernel. If it is 3.8.0-18-generic - try next steps Reboot and in GRUB select Advanced options Chose Ubuntu with Kernel ... (Any before -18) Also you can subscribe this bug at Launchpad, I hope they will fix it soon" + --- + ApportVersion: 2.12.5-0ubuntu2.1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: akoshodi 2460 F.... pulseaudio + /dev/snd/controlC0: akoshodi 2460 F.... pulseaudio + DistroRelease: Ubuntu 13.10 + HibernationDevice: RESUME=UUID=81c678ce-b670-40a5-a31f-adab1f716c43 + InstallationDate: Installed on 2013-10-25 (17 days ago) + InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) + Lsusb: + Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + Bus 001 Device 002: ID 04f2:b2f4 Chicony Electronics Co., Ltd + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + MachineType: Hewlett-Packard HP 655 Notebook PC + MarkForUpload: True + Package: linux (not installed) + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.11.0-12-generic root=UUID=12b5056c-0b3a-4453-b2ef-a8a558fad324 ro quiet splash acpi_backlight=vendor vt.handoff=7 + ProcVersionSignature: Ubuntu 3.11.0-12.19-generic 3.11.3 + RelatedPackageVersions: + linux-restricted-modules-3.11.0-12-generic N/A + linux-backports-modules-3.11.0-12-generic N/A + linux-firmware 1.116 + Tags: saucy + Uname: Linux 3.11.0-12-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + dmi.bios.date: 04/27/2012 + dmi.bios.vendor: Insyde + dmi.bios.version: F.02 + dmi.board.asset.tag: Base Board Asset Tag + dmi.board.name: 1885 + dmi.board.vendor: Hewlett-Packard + dmi.board.version: 66.11 + dmi.chassis.asset.tag: Chassis Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: Hewlett-Packard + dmi.chassis.version: Chassis Version + dmi.modalias: dmi:bvnInsyde:bvrF.02:bd04/27/2012:svnHewlett-Packard:pnHP655NotebookPC:pvr0793100000205210002620100:rvnHewlett-Packard:rn1885:rvr66.11:cvnHewlett-Packard:ct10:cvrChassisVersion: + dmi.product.name: HP 655 Notebook PC + dmi.product.version: 0793100000205210002620100 + dmi.sys.vendor: Hewlett-Packard ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1250363/+attachment/3906172/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1250363 Title: Kernel causes HDMI Audio, network cards to stop working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1250363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
