This week I got updates for several packages apparently related with sound management, as well as a new kernel. After update and reboot, the headphones jack started to work again. Connection/disconnection was correctly managed in PulseAudio, and audio quality was very good.
However, like in the previous cases, as soon as I plugged in both the headphones jack and the mic jack I got a peak of noise in my headset, and everything stopped working again. Even connecting the headphones only Thus, maybe the key is some problem with *both the mic and headphones jacks* connected at the same time. Finally, my laptop support service provided this fix for turning off the S/PDIF red light in the headphones connection: mkdir -p ~/.config/autostart tee -a ~/.config/autostart/disable_optical_led.desktop Then, reboot. Nevertheless, I have not tested this yet, just in case that for some reason it may disconnect the complete headphones jack, preventing me to test any solution for this problem. -- 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
