Thanks Hui Wang for your reply. adding "options snd-hda-intel probe_mask=0x1" made a significant change: my headphones now work! However, there is still no sound coming out of my speakers... I'll keep investigating a bit more today before installing a new kernel...
Also, my sound card seems to be normally powered up now (see the attached codec.txt file). I'll keep you posted, but if you came to have any other ideas of things I could try to now make my speakers work, I'll be very happy to try it. ** Attachment added: "Output of cat /proc/asound/card0/codec*" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1833161/+attachment/5271315/+files/codec.txt -- 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/1833161 Title: [HDA-Intel - HDA Intel PCH, playback] No sound at all Status in alsa-driver package in Ubuntu: New Bug description: Hello to all, My Ubuntu version is 18.04.02 LTS and I've setup a dual-boot with windows 10. Speakers and audio jack work totally fine under Windows 10, but they never work with Ubuntu. List of some of the things I've tried: 1) I've tried all the steps from the "Sound Troubleshooting Procedure" 2) I've tried installing the "oem-audio-hda-daily-dkms" package; 3) I've tried to install/remove/reinstall alsa-base, alsa-utils, pulseaudio, pavucontrol many times 4) I've played with the options in the file /etc/modprobe.d/alsa-base.conf: a) I've tried to add "options snd-hda-intel model=auto" and I also tried different models: auto, clevo, laptop-eapd, clevo m-720, generic, basic and even z71v position_fix=1. 5) I've tried adding : Code: [General] description = Headphones + Digital Output (S/PDIF) in the file "/usr/share/pulseaudio/alsa-mixer/paths/iec958-stereo-output.conf" 6) I've even tried a live USB stick with Ubuntu 19.04 (after reading somewhere that this was fixed on 19.04), but I found out that there was no sound on Ubuntu 19.04 as well.
