@David, No need to change alsa-base.conf after every update. And from -42, it enabled the dmic_detect by default. And it introduced a regression from stable patches. It is fixed in the -46.
Even in 18.04, you could still try with the symbollink. Please edit alsa-base.conf to remove the dmic_detect=0, then generate link as #10, please test it and upload the dmesg. After that, you could delete that symbollink and restore the dmic_detect=0 in the alsa-base.conf. 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
