It also affects Linux Mint 19.3. I had problems with audio also, so i had to add two lines:
echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf After executing these two commands audio is present again but still no success with internal microphone. Fortunately i have detachable microphone in my Creative Fatality headphones so after i have inserted this microphone in microphone socket, microphone has appeared inside pavucontrol and i am now able to record voice using this site: https ://online-voice-recorder.com/pl/ for example. I have noticed that there are more discussions about this problem: - https://online-voice-recorder.com/pl/ - https://github.com/thesofproject/linux/issues/1877 P.S. I have also tried to manually remap pins using: hdajackretask but with no success. ** Bug watch added: github.com/thesofproject/linux/issues #1877 https://github.com/thesofproject/linux/issues/1877 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523100 Title: Alsa not detecting internal microphone [ALC255] (Realtek) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
