I found the following: https://ubuntuforums.org/showthread.php?t=2421187
Based on that I edited /etc/modprobe.d/alsa-base.conf and added this to the end of the file: # Manual entry to allow audio via headphones because NVIDIA drivers break the built-in audio options snd-hda-intel model=clevo-p950 options snd-hda-intel probe_mask=0x1 with the probe_mask entry the headphones would work again. with the model entry the speakers also got to work. For people with other hardware and the same problem you can retrieve the codec of the system with $ cat /proc/asound/card0/codec* And check what model entry you need to use matching your codec in the following site: https://www.infradead.org/~mchehab/rst_conversion/sound/hd- audio/models.html This is in any case a workaround and it would be best if the update hadn't broken it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876499 Title: Using NVIDIA drivers 440 (tested) disables built-in laptop speakers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1876499/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
