Public bug reported: Sound works normally on the standard speakers, but when I put on the headphone I notice that only the left side emits sound, so I go to the settings and notice that the audio balance slider is well to the left, I set it to The center and everything goes on working normally.
In many cases I also notice that the sound is only emitted on the left side, even though the slider is centered, so again in this case I take the slider and move it out of the center and then center it again, and the sound is properly balanced normally. I already checked if it was the plugs and jacks, and they are perfect, otherwise I would not be able to get around the problem by changing the "slider" ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.4.0-72.93-generic 4.4.49 Uname: Linux 4.4.0-72-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.20.1-0ubuntu2.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D0p: titan 2299 F...m pulseaudio /dev/snd/controlC0: titan 2299 F.... pulseaudio CurrentDesktop: GNOME Date: Sat Apr 15 23:30:18 2017 InstallationDate: Installed on 2017-01-28 (77 days ago) InstallationMedia: Ubuntu-GNOME 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160720) PackageArchitecture: all ProcEnviron: LANGUAGE=pt_BR:pt:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=pt_BR.UTF-8 SHELL=/bin/bash SourcePackage: alsa-driver Symptom: audio Symptom_Card: Áudio interno - HDA Intel PCH Symptom_Jack: Black Headphone Out, Left Symptom_Type: Volume slider, or mixer problems Title: [37722QP, Realtek ALC269VC, Black Headphone Out, Left] volume slider problem UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 11/21/2013 dmi.bios.vendor: LENOVO dmi.bios.version: H1ET82BX(1.21) dmi.board.asset.tag: Not Available dmi.board.name: 37722QP dmi.board.vendor: LENOVO dmi.board.version: Win8 STD EM DPK TPG dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrH1ET82BX(1.21):bd11/21/2013:svnLENOVO:pn37722QP:pvrLenovoB490:rvnLENOVO:rn37722QP:rvrWin8STDEMDPKTPG:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 37722QP dmi.product.version: Lenovo B490 dmi.sys.vendor: LENOVO ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug xenial -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1683096 Title: [37722QP, Realtek ALC269VC, Black Headphone Out, Left] audio balance slider problem Status in alsa-driver package in Ubuntu: New Bug description: Sound works normally on the standard speakers, but when I put on the headphone I notice that only the left side emits sound, so I go to the settings and notice that the audio balance slider is well to the left, I set it to The center and everything goes on working normally.
