I can confirm I'm having the same problem with a similar HP Pavilion model under Ubuntu 16.04.There is no audio from the built in speakers but pavucontrol shows audio is being played.
Headphone jack works as expected.It is muted until I plug headphones in then the speakers mute. Removing headphones unmutes the speakers but no sound through them. I also checked on alsamixer and nothing is muted (except as described above.) malangaman@Pavilion-Laptop:~$ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC295 Analog [ALC295 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0e card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 8: HDMI 2 [HDMI 2] Subdevices: 1/1 Subdevice #0: subdevice #0 -- 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/1726075 Title: [HP Pavilion Power Laptop 15-cb0xx, Realtek ALC295, Speaker, Internal] No sound at all Status in alsa-driver package in Ubuntu: New Bug description: I cannot hear anything without headphone, the speaker don't work at all, even though after i set the speaker volume bar in the alsamixer panel ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: alsa-base 1.0.25+dfsg-0ubuntu5 ProcVersionSignature: Ubuntu 4.4.0-97.120-generic 4.4.87 Uname: Linux 4.4.0-97-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2.10 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: remaincool 1862 F.... pulseaudio CurrentDesktop: Unity Date: Mon Oct 23 00:57:26 2017 InstallationDate: Installed on 2017-07-06 (108 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:PCH failed Symptom_Card: 内置音频 - HDA Intel PCH Symptom_DevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: remaincool 1862 F.... pulseaudio Symptom_Jack: Speaker, Internal Symptom_Type: No sound at all Title: [HP Pavilion Power Laptop 15-cb0xx, Realtek ALC295, Speaker, Internal] No sound at all UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 06/02/2017 dmi.bios.vendor: Insyde dmi.bios.version: F.09 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 836B dmi.board.vendor: HP dmi.board.version: 46.20 dmi.chassis.type: 10 dmi.chassis.vendor: HP dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.09:bd06/02/2017:svnHP:pnHPPavilionPowerLaptop15-cb0xx:pvrType1ProductConfigId:rvnHP:rn836B:rvr46.20:cvnHP:ct10:cvrChassisVersion: dmi.product.name: HP Pavilion Power Laptop 15-cb0xx dmi.product.version: Type1ProductConfigId dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1726075/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
