@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 Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1868319 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1868319/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
