I followed this link : https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS and installed the package.
My Nvidia device has now moved from Card 2 to Card 1 and the system settings->sounds dialog now shows a HDMI/displayport 2 device. I no longer get random crashes of the kernel from snd_hda_intel module. Pulse audio no longer reports that it cannot initialise the device. Current error report from pulseaudio is: Apr 22 12:43:28 Feynmann pulseaudio[3089]: [pulseaudio] source.c: Default and alternate sample rates are the same.

Which does not look serious. However sound still does not work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1170315 Title: Sound device not detected on Nvidia card using nouveau driver Status in “pulseaudio” package in Ubuntu: New Bug description: I upgraded from 12.10 to 13.04. The HDMI device on my Nvidia graphics card disappeared. I have the following: - tried the Nvidia-310, Nvidia-304 drivers - reverted to the Nouveau driver - purged and re-installed pulseaudio. I also ran pavucontrol - this allowed me to specify the HDMI channel 3 (which corresponded to the Nvidia card) in the configuration and I then ran the Sound settings dialog from System Settings. Sound still did not work. Incidental issues which may or may not be important: - rebooting the PC is flaky - some times the system just hangs waiting for the network card to configure. - - I once had a kernel panic because of an illegal paging request from the snd-hda-intel driver ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: pulseaudio 1:3.0-0ubuntu5 ProcVersionSignature: Ubuntu 3.8.0-18.28-generic 3.8.6 Uname: Linux 3.8.0-18-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.9.2-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: paul 5631 F.... pulseaudio /dev/snd/controlC1: paul 5631 F.... pulseaudio Date: Thu Apr 18 12:14:43 2013 InstallationDate: Installed on 2012-12-10 (129 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MarkForUpload: True SourcePackage: pulseaudio Symptom: audio Symptom_Card: HDA-Intel - HDA NVidia Symptom_Jack: Digital Out, HDMI Title: [MotherBoard H67ITX-C-E, Nvidia GPU 0b HDMI/DP, Digital Out, HDMI] Pulseaudio fails to detect card UpgradeStatus: Upgraded to raring on 2013-04-15 (2 days ago) dmi.bios.date: 04/13/2012 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 4.6.4 dmi.board.asset.tag: NA dmi.board.name: H67ITX-C-E dmi.board.vendor: ZOTAC dmi.board.version: 02/03/05 dmi.chassis.asset.tag: NA dmi.chassis.type: 3 dmi.chassis.vendor: NA dmi.chassis.version: NA dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr4.6.4:bd04/13/2012:svnMotherBoardByZOTAC:pnMotherBoardH67ITX-C-E:pvrMotherBoard02/03/05:rvnZOTAC:rnH67ITX-C-E:rvr02/03/05:cvnNA:ct3:cvrNA: dmi.product.name: MotherBoard H67ITX-C-E dmi.product.version: MotherBoard 02/03/05 dmi.sys.vendor: MotherBoard By ZOTAC To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1170315/+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
