Executing the following command afterwards solves the problem. $ pactl set-sink-volume <SINK-NUM> +0 Attached is three outputs of `pactl list`: 1) "hdmi-before" : taken when HDMI output is working as it should 2) "hdmi-after" : this is taken after changing away from the HDMI output (to laptop speaker), and back to HDMI again -- reported volume level is 50%, but real output level is 100%. 3) "hdmi-after-adjust" : taken after executing the command listed above (which sets real output level to 50%) If it has any interest, I used the built in system settings to change sound output (even though the same problem occurs when doing so from the command line). ---- I'm using Ubuntu 14.04.1 $ pulseaudio --version pulseaudio 4.0 $ pactl --version pactl 4.0 Compiled with libpulse 4.0.0 Linked with libpulse 4.0.0 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: pulseaudio 1:4.0-0ubuntu11 ProcVersionSignature: Ubuntu 3.13.0-36.63-generic 3.13.11.6 Uname: Linux 3.13.0-36-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: rasmus 2685 F.... pulseaudio /dev/snd/pcmC0D0c: rasmus 2685 F...m pulseaudio /dev/snd/pcmC0D3p: rasmus 2685 F...m pulseaudio CurrentDesktop: Unity Date: Wed Oct 8 19:49:58 2014 InstallationDate: Installed on 2014-05-23 (138 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) SourcePackage: pulseaudio UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 07/04/2012 dmi.bios.vendor: LENOVO dmi.bios.version: GAET35WW (1.12 ) dmi.board.asset.tag: Not Available dmi.board.name: 33643EG dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGAET35WW(1.12):bd07/04/2012:svnLENOVO:pn33643EG:pvrThinkPadEdgeS430:rvnLENOVO:rn33643EG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 33643EG dmi.product.version: ThinkPad Edge S430 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1378969/+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
