@David, Your machine is a coffeelake platform, there is no sof-firmware for this platform in the 19.10. you could use a workaround to let sound work with legacy hda driver: edit /etc/modprobe.d/alsa-base.conf, add "options snd-hda-intel dmic_detect=0", reboot.
Or you could manually symbollink a firmware for coffeelake: cd /lib/firmware/intel/sof;sudo ln -s cnl/intel/sof-cnl-v1.3-0f73628.ri sof-cfl.ri;reboot If it still doesn't work after generating link, please upload the dmesg and upload the output of 'ls -la /lib/firmware/intel/sof' thx. -- 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/1868319 Title: PCI/internal sound card not detected Status in alsa-driver package in Ubuntu: Confirmed Bug description: Any time now, the sound card was deactivated, and it appears as a "Dummy device".
