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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791806 Title: alsa does not detech headphone output on Clevo P651RS laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791806/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
