Update: as per request from my laptop vendor, I updated the BIOS firmware of my computer(Clevo P650HP), then reinstalled Ubuntu 18.04.1.
After this process I was able to trace the source (or one of them) of this bug: - Right after the fresh install, the headphones jack and line-out jack work fine (both). - When I attempt to connect a gaming headset with headphones + mic connectors, that is, when I plug in the headphones and the mic jacks simultaneously, the headphones jack stops working. - From that point on, I cannot recover the auto-detection of headphones connection when I plug in the jack in the connector. PulseAudio does not switch to headphones out, it remainst at speakers. Alsamixer does not mute all other channels except for the headphones. Hope this helps. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1791806 Title: alsa does not detech headphone output on Clevo P651RS laptop Status in linux package in Ubuntu: Confirmed Bug description: Even though there is a duplex S/Pdif + Headphones out output the following line is observed: [ 13.617774] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC898: line_outs=1 (0x17/0x0/0x0/0x0/0x0) type:line [ 13.617776] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=1 (0x14/0x0/0x0/0x0/0x0) [ 13.617778] snd_hda_codec_realtek hdaudioC0D0: hp_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 13.617779] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ 13.617780] snd_hda_codec_realtek hdaudioC0D0: dig-out=0x1e/0x0 [ 13.617781] snd_hda_codec_realtek hdaudioC0D0: inputs: [ 13.617782] snd_hda_codec_realtek hdaudioC0D0: Mic=0x18 [ 13.617783] snd_hda_codec_realtek hdaudioC0D0: Internal Mic=0x12 [ 13.632784] input: HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1f.3/sound/card0/input19 [ 13.632851] input: HDA Intel PCH Line Out as /devices/pci0000:00/0000:00:1f.3/sound/card0/input20 [ 13.632905] input: HDA Intel PCH HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input21 [ 13.632953] input: HDA Intel PCH HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input22 [ 13.632989] input: HDA Intel PCH HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input23 [ 13.633108] input: HDA Intel PCH HDMI/DP,pcm=9 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input24 [ 13.633291] input: HDA Intel PCH HDMI/DP,pcm=10 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input25 --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: lehel 1673 F.... pulseaudio CurrentDesktop: XFCE DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=14306ed9-327a-44fd-8c4d-2eba92aa55c0 InstallationDate: Installed on 2017-04-30 (499 days ago) InstallationMedia: Xubuntu 17.04 "Zesty Zapus" - Release amd64 (20170412) MachineType: Notebook P65_67RSRP Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-34-lowlatency root=/dev/mapper/xubuntu--vg-root ro noquiet nosplash i915.modeset=1 acpi_osi=!
