And I can't install an unsigned kernel too, as I'm using UEFI laptop, it won't let me install the unsigned kernel. ** Attachment added: "Screenshot from 2019-08-11 11-13-39.png" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100/+attachment/5281953/+files/Screenshot%20from%202019-08-11%2011-13-39.png -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
