Hi brian, Your BIOS is broken, because it does not tell us where the different connectors are connected on the codec chip. Later kernels rely more heavily on this information.
Here's the recommended way to get the information Raymond (and I) are asking for. First you need the snd-hda-tools package: sudo add-apt-repository ppa:diwic/hda sudo apt-get update sudo apt-get install snd-hda-tools It looks like the Gateway E4300 has a mic and headphone in the front and three jacks in the back, is this correct? Plug something into the first jack and execute: sudo hda-jack-sense-test -a Notice that one of the lines should say "present = yes". Now unplug the first jack and plug in the second jack. Execute "sudo hda-jack-sense- test -a" again, and repeat for all five jacks. Given the output of hda-jack-sense-test, you should be able to figure out what pin is connected to which jack. E g, maybe pin 0x0a is front headphone and 0x0b is rear mic, etc. This is the information we need to know. ** Summary changed: - alc880 - no sound after 12.10 upgrade, only "dummy output" appears + [Gateway E4300] alc880 - no sound after 12.10 upgrade, only "dummy output" appears ** Changed in: alsa-driver (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1106334 Title: [Gateway E4300] alc880 - no sound after 12.10 upgrade, only "dummy output" appears Status in “alsa-driver” package in Ubuntu: Incomplete Bug description: after upgrading to 12.10 my audio stopped working. nope, it's not just muted, checked alsamixer for system muting, no problem there. the audio card isn't showing up in pulseaudio, just the dummy output ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: pulseaudio 1:2.1-0ubuntu4 ProcVersionSignature: Ubuntu 3.5.0-22.34-generic 3.5.7.2 Uname: Linux 3.5.0-22-generic i686 ApportVersion: 2.6.1-0ubuntu9 Architecture: i386 AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/by-path', '/dev/snd/controlC0', '/dev/snd/hwC0D2', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Sat Jan 26 12:58:11 2013 InstallationDate: Installed on 2012-03-29 (303 days ago) InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MarkForUpload: True ProcEnviron: TERM=xterm PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: pulseaudio Symptom: audio Symptom_Card: HDA-Intel - HDA Intel Symptom_Jack: Line Out, Front Title: [E4300, Realtek ALC880, Line Out, Front] Pulseaudio fails to detect card UpgradeStatus: Upgraded to quantal on 2013-01-26 (0 days ago) dmi.bios.date: 02/15/2005 dmi.bios.vendor: Intel Corp. dmi.bios.version: SE91510J.15A.2300.2005.0215.1823 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: D915GUX dmi.board.vendor: Intel Corporation dmi.board.version: AAC85199-202 dmi.chassis.asset.tag: NONE dmi.chassis.type: 3 dmi.chassis.vendor: Gateway dmi.chassis.version: WTN01A01 dmi.modalias: dmi:bvnIntelCorp.:bvrSE91510J.15A.2300.2005.0215.1823:bd02/15/2005:svnGateway:pnE4300:pvr4000983:rvnIntelCorporation:rnD915GUX:rvrAAC85199-202:cvnGateway:ct3:cvrWTN01A01: dmi.product.name: E4300 dmi.product.version: 4000983 dmi.sys.vendor: Gateway To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1106334/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
