According to the information providedin the report, there are multiple HDMI connections, at least according to pulse. How do you have your speakers connected to your system? If you are using external speakers, please make sure that the analog line-out/headphones out is selected in MATE's sound settings.
If that still doesn't help, try updating the ALSA drivers, as outlined at https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1604497 Title: Pulseaudio does not start Status in pulseaudio package in Ubuntu: New Bug description: I'm using Ubuntu Mate 16.04 with the current updates. When I start the computer, pulseaudio is not working after I've logged in. If I type: start-pulseaudio-x11 from the command line, I get "Connection failure: Connection refused pa_context_connect() failed: Connection refused" and I cannot play any sound. If I type pulseaudio& on the command line, I can get sound in some applications (e.g. Audacity) but not others (e.g. Firefox or other browsers). At some point a command line message appears that says: "E: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." I'm not clear why there's a reference to bluez5-util, since I don't have bluetooth on my machine. pulseaudio: Installed: 1:8.0-0ubuntu3 Candidate: 1:8.0-0ubuntu3 Version table: *** 1:8.0-0ubuntu3 500 500 http://gb.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.4.0-31.50-generic 4.4.13 Uname: Linux 4.4.0-31-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 CurrentDesktop: MATE Date: Tue Jul 19 17:43:11 2016 InstallationDate: Installed on 2016-05-10 (70 days ago) InstallationMedia: Ubuntu-MATE 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:NVidia failed Symptom_Card: GK208 HDMI/DP Audio Controller - HDA NVidia Symptom_Jack: Digital Out, HDMI Symptom_Type: No sound at all Title: [Z97X-UD3H, Nvidia GPU 51 HDMI/DP, Digital Out, HDMI] No sound at all UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/21/2015 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: F8 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: Z97X-UD3H-CF dmi.board.vendor: Gigabyte Technology Co., Ltd. dmi.board.version: x.x dmi.chassis.asset.tag: To Be Filled By O.E.M. dmi.chassis.type: 3 dmi.chassis.vendor: Gigabyte Technology Co., Ltd. dmi.chassis.version: To Be Filled By O.E.M. dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrF8:bd04/21/2015:svnGigabyteTechnologyCo.,Ltd.:pnZ97X-UD3H:pvrTobefilledbyO.E.M.:rvnGigabyteTechnologyCo.,Ltd.:rnZ97X-UD3H-CF:rvrx.x:cvnGigabyteTechnologyCo.,Ltd.:ct3:cvrToBeFilledByO.E.M.: dmi.product.name: Z97X-UD3H dmi.product.version: To be filled by O.E.M. dmi.sys.vendor: Gigabyte Technology Co., Ltd.
